Carbon Emission Reduction Strategies May Undermine Tropical Biodiversity Conservation

ScienceDaily (Nov. 25, 2010)Conservationists have warned that carbon emission reduction strategies such as REDD may undermine, not enhance, long-term prospects for biodiversity conservation in the tropics.

Their warning comes only days ahead of the Cancun COP 16 climate change talks (Nov. 29 to Dec. 10, 2010).
REDD is a United Nations designed mechanism for carbon emission trading that provides financial compensation to developing countries for improved management and protection of their forest resources. If it works, REDD could strengthen the global fight against climate change, and create an opportunity for carbon-rich tropical countries to protect threatened biodiversity as a co-benefit of maintaining forests and the carbon they store.

Writing in the journal Carbon Balance and Management, a network of conservation scientists, including University of Kent's Dr Matthew Struebig, use data for Indonesia, a species-rich tropical country and the world's third largest source of carbon emissions, to highlight ways in which emission reduction strategies could turn sour for wildlife.

Global Warming Improves Biodiversity

Several recent alarmist news reports have claimed 'biodiversity" is the latest eco-scare:
Adding to the scientific and common sense evidence that global warming is beneficial to biodiversity is this new paper showing how global cooling causes extinction and that biodiversity decreases towards the poles almost everywhere in the world.

Disappearing Glaciers Enhanced Biodiversity

ScienceDaily (Oct. 4, 2010) — Biodiversity decreases towards the poles almost everywhere in the world, except along the South American Pacific coast. Investigating fossil clams and snails Steffen Kiel and Sven Nielsen at the Christian-Albrechts-Universität zu Kiel (CAU) could show that this unusual pattern originated at the end of the last ice age, 20.000 to 100.000 years ago. The retreating glaciers created a mosaic landscape of countless islands, bays and fiords in which new species developed rapidly -- geologically speaking. The ancestors of the species survived the ice age in the warmer Chilean north.

The exceptional biodiversity of the southern Chilean coast is known for a long time. More than 500 species of clams and snails are known from this area, twice as many as at comparable latitudes in the northern hemisphere. The reasons for this diversity were so far speculative, report Kiel and Nielsen in the current issue of the scientific journal Geology: "Opinions include that southern Chile is a museum of diversity where species survived for millions of years in addition to new arrivals; or that Antarctic species colonized this area from the south." Their analysis of around 35.000 fossil clams and snails, belonging to about 400 species, allowed the paleontologists to draw some more precise conclusions: "Our fossils reject both hypotheses. Biodiversity in this area always decreased toward the south in the geologic past, and we didn't find any intruders from Antarctica," explains Steffen Kiel. In addition, the researchers found that the vast majority of species and genera that lived in that area only 16 million years ago had become extinct. "This area is certainly not a museum of biodiversity," adds Kiel.

The most species-rich groups of animals in the southern Chilean fiordlands are those inhabiting rocky shores. This is exactly the habitat that was created when the glacier retreated from their marine termini. "Molecular biologic investigations on phylogenetic relationships of these species show that they are geologically very young and descended from North Chilean ancestors. This agrees well with our results," says Sven Nielsen, who has been working on Chilean fossils for many years. "Charles Darwin, who was the first to discover fossils in this area during his voyage on the 'Beagle', would have been fascinated."

This research shows that for species conservation not only single, exceptional habitats need to be protected, but that a diversity of habitats needs be conserved to maintain a healthy biodiversity.

Paper: Global Warming Improves Biodiversity

Several recent alarmist news reports have documented 'biodiversity" as the latest eco-scare:
However, a recent paper finds that back when the entire earth was like the modern tropics today, as Al Gore tells us we are headed again due to our own sins, biodiversity exploded around the entire planet, with crocodiles and palm trees in the high arctic... 

Tropical Biodiversity Explained by Steady Temperatures 
By OurAmazingPlanet Staff 25 July 2010 02:15 pm ET

        The astounding array of species that call the tropics home is the result of the near-constant year-round temperatures found in these areas, a new study suggests.
        The study, which surveyed insect diversity at a variety of latitudes and points in Earth's history, answers a question that has bugged biologists for centuries. It also shows that the exceptional biodiversity of the tropics is not a result of higher temperatures or more sunlight, as once assumed.
        The findings, detailed in the August issue of the journal Paleobiology, also suggest, intriguingly, the world is likely far less diverse today than it was tens of millions of years ago, when the entire Earth had consistent year-round temperatures, much like the modern tropics.

Debunking the latest asinine warmist claim: 'We're going to end up with just one kind of butterfly'

According to 'journalist' David Biello of 'Scientific' American, "We're going to end up with just one kind of butterfly," due to an alleged man-made biodiversity crisis. While Biello and others attempt to make butterflies the new poster child of global warming, many peer-reviewed studies instead document an increase in overall land and marine biodiversity with warming. It is well known that global warming greatly increased biodiversity in the past. Furthermore, conservationists have warned that carbon emission reduction strategies may undermine tropical biodiversity. As to butterflies specifically, multiple studies have found that all-species population counts and biodiversity are stable to increasing since the ice age scare of the 1970's.

Humans need to adapt if planet is to survive technology 

By Tanya Lewis LiveScience 9/13/13



Butterflies are doing just fine


WASHINGTON — Charles Dickens could have been talking about the 21st century when he wrote the lines: "These are the best of times, these are the worst of times." Technology can extend human life and take us into space, but it is also destroying the environment and threatening the survival of other species and humanity.

Moving forward, what parts of nature should humans preserve? What will the future look like? Will we develop a stable, long-term relationship with technology? These were some of the issues a group of scientists and humanists tackled Thursday in a symposium held here at the Library of Congress.

"The hallmark of the human species is great adaptability," said David Grinspoon, the Baruch S. Blumberg NASA/Library of Congress chair in astrobiology at the Kluge Center, who led the conversation.

The question is, he said, "Can we keep it going?"

The anthropocene era

Humans may not be able to predict the future of civilization, but we can gain insight from scientific models, history and human imagination, Grinspoon said. [The 10 Scariest Sci-Fi Series]

A number of scientists have begun using the term "anthropocene" to describe the geologic period of Earth's history in which human activities are having a significant impact on the planet's ecosystems.

One problem humanity faces is the loss of biodiversity. Everyone's familiar with the threat to charismatic megafauna, such as rhinos and tigers, but what about less obvious biological casualties? As journalist and discussion participant David Biello of Scientific American said, "We're going to end up with just one kind of butterfly."

The butterfly became a recurring theme in the conversation, as panelists debated the purpose of preserving a species. "Does the butterfly have the right to exist just because it's there?" said materials scientist Odile Madden of the Smithsonian's Museum Conservation Institute.


Humanity must save the genetic information that represents butterflies and other organisms, Biello said. But that's not enough. "The genome is necessary, but not sufficient," he said, adding that the information about how a species interacts with its ecosystem must also be preserved.

Tragedy of the commons


Human adaptability and ability to modify our surroundings have kept our species alive thus far. But in order to make it through the next century, humanity must view itself as one species, the panelists said.

"There's an immense need for a planetary narrative," said paleoanthropologist Rick Potts, director of the Smithsonian's Human Origins Program and curator of anthropology at the National Museum of Natural History. We also need moral responsibility, Potts added.

Potts likened the lack of responsibility to "the tragedy of the commons," a concept in economics in which people disregard the depletion of a shared resource, acting in their own self-interest rather than that of the group.

The question of whether we will survive in the face of an increasingly technical culture comes down to what is meant by the term "we."

Humans have made a division between the natural world and the human world, Potts said, "but the evolution of human culture is a natural phenomenon."

New paper finds biodiversity was greatest during Roman & Current Warming Periods

A paper published today in The Holocene examines biodiversity in Romania over the Holocene [the past 11,500 years] and finds the periods with the greatest biodiversity were during the Roman Warm Period 2000 years ago, and over the past 500 years during the current warming period. Once again, the data demonstrates warming is beneficial to plant and animal life. According to the authors, "Most distinct episodes of enhanced floristic richness are evident during the Roman Period (2000 cal. yr before the present), and over the last 500 calendar years before the present."

Abstract

An understanding of contemporary and likely future biodiversity requires knowledge of how past human societies have shaped diversity patterns. Here, we use long-term pollen data sets extending from lowlands to subalpine environment in the Carpathian region (Romania) with the aim of exploring the relationship between landscape openness, anthropogenic disturbance, elevation and vegetation richness over the Holocene. We found that landscape openness represents a significant driver of pollen richness: The more open sites from mid (440–750 m) and high elevations (1550–1850 m) showed on average greater diversity than more forested upland sites (1050–1360 m). For the first time, our results show pollen richness patterns along elevation gradients that remain constant over the Holocene. Although significant only over the last 3000 cal. yr BP, these elevational patterns become accentuated with stronger evidence of anthropogenic impact. We also found a strong link between diversity change and major land use strategies of prehistoric societies, demonstrating the potential of pollen richness to be used as a tool to depict the ecological impact of human disturbance on diversity. Most distinct episodes of enhanced floristic richness are evident during the Roman Period (2000 cal. yr BP), and over the last 500 cal. yr BP. Recent anthropogenic activity negatively impacted diversity in mountainous areas mainly through plantations; the lack of sites in agriculture landscapes however limits our inference for this type of setting. The maintenance of habitat diversity is key to maintaining high levels of diversity. While there is temporal consistency in the diversity pattern in records from similar climate and vegetation settings, comparison of diversity from different vegetation assemblages and levels landscapes openness should be interpreted cautiously.

Biodiversity alarmism on the brink

The September 2011 edition of Nature Climate Change claims biodiversity is on the brink and that we "cannot wait for greater certainty in our estimates of extant biodiversity and predictions of its fate." The same article admits we are not even close to being able to measure biodiversity, with only 2 million species identified out of a total of "5.5 million to tens of millions" of species yet to be identified. Furthermore, the article admits "assessing the extent to which regional changes in biodiversity are caused by greenhouse-gas warming has proven particularly intractable, not least because of the need to disentangle the effects of climate change from those of other drivers such as pollution or overexploitation." Nonetheless, the article claims "one in every species could face extinction by 2100 from climate change alone" and that this "startling figure may well be conservative."

This highly-speculative conclusion is based on subdividing each species based upon differences in mitochondrial DNA. In this same sense, one could say "one in the Homo sapiens species could face extinction by 2100," since just like the genome is unique to each human, the DNA of human mitochondria is also highly variable between individuals. For example, a study found biodiversity of mitochondrial DNA between 105 randomly selected Croatians was 95% just based on looking at only 2 regions within the mitochondrial DNA genome itself. The biodiversity of the mitochondrial DNA of other species is also highly diverse and thus, the claim "one in every species could face extinction by 2100" is another example of pseudo-science feeding the alarmist mantra.

New study confirms global warming increases marine fish biodiversity

In another blow to the biodiversity eco-scare movement, a paper published last week confirms that global warming results in a net increase in marine fish biodiversity, even in areas of "low connectivity" such as the Baltic Sea. 

What is the effect of climate change on marine fish biodiversity in an area of low connectivity, the Baltic Sea?

Jan Geert Hiddink, Chris Coleby

ABSTRACT:
Aim  Climate change could result in an increase in species richness because large-scale biogeography suggests that more species could be gained from equatorial regions than may be lost pole-ward. However, the colonization of newly available habitat may lag behind the rate dictated by climatic warming if there exists of a lack of connectivity between ‘donor’ and receiving areas. The objective of this study was to compare how regional warming affected the biodiversity of marine fish in areas that differed in their connectivity in the Baltic Sea.

Location  North-east Atlantic, Kattegat and Baltic Sea.

Methods  The total species richness and the mean species richness from scientific surveys were related to changes in temperature and salinity. Changes in the extent of the distribution of individual fish species were related to the latitudinal distribution, salinity tolerance, maximum body size and exploitation status to assess to what extent climate change and fishing impacts could explain changes in species richness in the Baltic.

ResultsRising temperatures in the well-connected Kattegat correlated to an increase in the species richness of fish, due to an increase in low-latitude species. Unexpectedly, species richness in the poorly connected Baltic Sea also increased. However, the increase seems to be related to higher salinity rather than temperature and there was no influx of low-latitude species.

Main conclusions  These results do not support the hypothesis that low-connectivity areas are less likely to see increases in species richness in response to warming. This indicates that the effect of climate change on biodiversity may be more difficult to predict in areas of low connectivity than in well-connected areas.

The Lemur Demur

The alarmist pronouncement today,  Biodiversity Hot Spots More Vulnerable to Global Warming Than Thought, turns out to be a very far-fetched hypothesis based on the disproven notion that global warming causes more frequent El Niños, which then might cause more heavy rains in Madagascar, which then might "anecdotally knock fruit off the trees when lactating lemurs need it most, and may even kill trees outright, " and thus might malnurish lemur babies...

To further 'support' this outlandish theory, the article states, "Not only that, cyclones making landfall have a direct negative effect on the fecundity -- or potential reproductive capacity -- of lemurs. The team also discovered that fecundity "was negatively affected when El Niño occurred in the period before conception, perhaps altering ovulation, or during the second six months of life, possibly reducing infant survival during weaning." Note to team: There has been no increase in frequency or magnitude of El Niño events since 1856, and these events have occurred in a normal distribution despite steadily rising CO2 levels, and tropical cyclone activity is at a 30 year low.  In addition, global warming has been shown to cause an explosive increase in biodiversity.

This is another study which makes one wonder whether it is possible for scientists to get funding for anything in which the grant proposal does not mention a link to anthropogenic global warming.

ScienceDaily (Aug. 12, 2010) — Global warming may present a threat to animal and plant life even in biodiversity hot spots once thought less likely to suffer from climate change, according to a new study from Rice University.
      Research by Amy Dunham, a Rice assistant professor of ecology and evolutionary biology, detailed for the first time a direct correlation between the frequency of El Niño and a threat to life in Madagascar, a tropical island that acts as a refuge for many unique species that exist nowhere else in the world. In this case, the lemur plays the role of the canary in the coal mine.

Only global poverty can save the planet, insists WWF




Analysis Extremist green campaigning group WWF - endorsed by no less a body than the European Space Agency - has stated that economic growth should be abandoned, that citizens of the world's wealthy nations should prepare for poverty and that all the human race's energy should be produced as renewable electricity within 38 years from now.

Most astonishingly of all, the green hardliners demand that the enormous numbers of wind farms, tidal barriers and solar powerplants required under their plans should somehow be built while at the same time severely rationing supplies of concrete, steel, copper and glass.

The WWF presents these demands in its just-issued [1] Living Planet Report for 2012. It's a remarkable document, not least for the fact that it is formally endorsed for the first time by the European Space Agency (ESA) - an organisation which would cease to exist in any meaningful form if the document's recommendations were to be carried out.

The report is also unusual in that it seeks to set policy on economics and energy, but doesn't anywhere give any figures expressed in units of energy (watt-hours, joules etc) or currency (dollars, euros or what have you). Instead the WWF activists prefer to base their argument on various indices invented either by themselves or by other international non- or quasi-governmental organisations.

For instance one key figure used in the report is the Living Planet Index, invented by the WWF, which apparently shows "trends in the overall state of global biodiversity".

It does this by examining the number of individuals (or sometimes pairs) in various local populations of 2,688 selected species - of vertebrates only. Every two years WWF changes what species and populations are included, in large numbers: and anyone would acknowledge that a limited, localised picture of a couple of thousand vertebrate-only species is an utterly minuscule, extremely selective pinpoint on the picture of all the Earth's life.

Nonetheless WWF think that their LPI number offers conclusive proof that "biodiversity has decreased globally".

This is bad, because:
Biodiversity is vital for human health and livelihoods ...
All human activities make use of ecosystem services – but can also put pressure on the biodiversity that supports these systems.
If that's not enough for you, the document is liberally spattered with case studies showing how various animal populations have plunged. For instance there are now many fewer wild tigers than there were in 1970, which is plainly a bad thing for human health and livelihoods.

The report then assumes that global resources in general are limited, which is easily achieved by measuring them in terms of "biocapacity" expressed in hectares of Earth surface, and further stipulating that no resources can come from beyond Earth (which seems an odd idea for a major space agency to endorse, but there). WWF goes on to assign numbers showing how much of these hectare-resources everyone is using, their "ecological footprint".

In these terms, the only people on Earth who are living within their means are those in the poorest nations - their "footprint" exactly matches the "biocapacity" in their countries (doubtless a coincidence) offering a picture of the sort of life all human beings could aspire to in a WWF-run world. Middle-income nations use more "biocapacity" than they actually have, and high-income ones - all the ones where you as a Register reader are most likely to live - use nearly twice as many eco-resources as they produce.
What does this mean?
The Earth’s natural capital – biodiversity, ecosystems and ecosystem services – is limited ...
Human demands on the planet exceed supply.
The WWF eco-nomists also argue that human beings actually don't - or anyway, shouldn't - want to get richer, as people getting rich means economic growth and that (regardless of what all world governments and almost all economists think, especially right now) is a Bad Thing as it leads to consumer demand which leads to resources and energy being used.

"We need to measure success beyond GDP," says WWF, an argument they've made before [2]. In particular the organisation argues that "human development" or the still-flakier metric "inequality adjusted human development" is a far better one than GDP per capita. (One may note that under the normal HDI (Human Development Index) [3] it is better to live in Ireland, Hong Kong, Israel, Korea, Slovenia, Spain, Italy or the Czech Republic than in the UK.)

As the green hardliners note:
In countries with a low level of development, [HDI] development level is independent of per capita [ecological] Footprint.
As development increases beyond a certain level, so does per person Footprint — eventually to the point where small gains in development come at the cost of very large Footprint increases.
Or, paraphrased, provided that development and consumption are both miserably low, you can achieve some development without noticeably increasing consumption. Of course only a cynic would suggest that the very design of the "human development" index - whether adjusted for inequality or not - ensures that there will come a point where only tiny increases in development can be achieved no matter the resources used. This is because the Human Development is on a scale from zero to 1, with 1 being unachievable.

It's not just resources that are limited, in the WWF's view: human potential itself is up against a hard limit beyond which the race cannot ever advance. Even progress thus far, as seen in the wealthy nations, has been achieved only by an unfair and wasteful over-use of precious resources: we rich Westerners are already beyond the practical limits that humans should ever aspire to achieve in terms of health, wealth - and even of education.

That's not economics - that's religion. And not very nice religion either.

All this is followed up with some standard rehashing of the standard carbon-driven apocalypse arguments, so setting the stage for WWF's policy agenda. Some of it is relatively uncontroversial: creation of nature reserves, efforts to control overfishing, efforts to ease deforestation.

But then we get onto the big stuff. First up, there must be an "immediate focus" on "drastically shrinking the ecological footprint of high income populations".

That means you, Reg reader: you are to accept a massively lower standard of living, in order to reduce your "footprint" to match your nation's "biocapacity". Then you'll have to take another cut, because your nation - being rich - has more "biocapacity" than a poor country does (despite their claim that planetary resources are finite, WWF acknowledges that new "biocapacity" can be created in the form of cropland, forests etc), but this should be shared with the poorer lands under "equitable resource governance".
That means less heating when it's cold - no cooling at all, probably, when it's hot. It means sharply limited hot water: so dirtier clothes, dirtier bedding and a dirtier you - which will be nice as you will also have to live in a smaller home and travel almost exclusively on crowded buses or trains along with similar smelly fellow eco-citizens. Food will be scarcer and realistically much less nutritious (milk for kids will be a luxury, let alone meat, fruit, coffee, that sort of stuff. Get ready to eat a lot of turnips, if you're a Brit.)

Windfarms, tide barriers, solar panels to power EVERYTHING. But you can't have any concrete or steel or iron or copper. Or glass. Or shipping either. Get on with it!

All this means more disease, and there will also be less health care (only rich nations can afford proper health care for all or most).

Everything - everything - will be a lot more expensive: materials, tools, books, booze, gadgets, clothes. Holidays will be bus trips to the seaside if you're lucky, not trips overseas by plane or car. So it goes on.
Even this grim poverty-stricken dystopia, though, is not the biggest of the WWF demands. The real biggy is that by the year 2050 all energy is to be supplied in the form of renewables-generated electricity, that is by means of windfarms, solar plants, tidal barriers and so forth. Foralmost all of human history and prehistory [4] we have burned things to generate energy - it is one of the things that makes us human - but now, within a single generation, that is to almost completely stop. After a million years, the fires will go out.

That won't be simple. At the moment, the great bulk of energy used by humanity is not electrical at all - it is generated directly by burning fossil fuels (a little, by burning biofuel such as wood). What electrical energy there is (only a tenth of the total even in countries like the UK) is also mostly fossil-generated right now, and the small proportion of this small proportion which isn't fossil is mainly nuclear, not renewable - presumably to disappear for some reason under the WWF plan.

Then, regardless of the impression one gets from the media, it is not perhaps-dispensable things like aviation or gadgets which use most of our energy. Overwhelmingly, energy is used either in the home, by industries - including for example the health [5] and construction industries - and for ordinary everyday forms of transportation.

And as even WWF acknowledges, billions of people worldwide have no access to any electricity grid at all.

Yet nonetheless - without giving any specifics as to how - WWF considers that just about everyone on Earth can be hooked up to an electrical grid and that these grids can be entirely powered by renewables; and the transport sector can be pretty much entirely electrified; and all of industry, all the mines and smelters and refineries and factories, all of it, can go electric. All this, within 38 years.
There will need to be quite a lot of industry remaining. Even quite limited renewable power goals - for instance (pdf) [6] getting the US onto 20 per cent wind electricity by say 2030 (in other words achieving roughly 2 per cent renewables power for the US) would require every year:
About 6.8 million metric tons of concrete, 1.5 million metric tons of steel, 310,000 metric tons of cast iron, 40,000 metric tons of copper, and 380 metric tons of the rare-earth element neodymium.
Even this equates to 3 per cent of current US domestic consumption of steel, iron and copper - much more in the case of neodymium. To achieve full renewable power you would be talking about doubling or tripling production of concrete, steel and copper. At the moment these materials are produced by burning vast amounts of fossil fuels, so even if you managed to slash use of energy in all other sectors then huge increases in energy demand for materials to build the windmills would cause a massive further demand for more windmills and more materials for them and so on. And all this stuff would have to be hauled all over the place, as renewable plants normally have to be built in inaccessible locations - hauled by electric transport!

But in the WWF cloud-cuckoo-land all this steel and concrete and copper is probably, somehow, unnecessary. The 2012 report says that there must be:
Ambitious energy demand management, especially in sectors with limited renewable options that are likely to be dependent on bioenergy. (Aviation, shipping and high heat industrial applications are likely to be among these.)
"Demand management" is eco-nomics code for "rationing, or making mostly illegal". Rationed aviation is not a big deal except socially (no flying means a return to the days when only the rich and powerful ever got to travel other than for war and migration).

But rationed shipping, in a world which needs to shift gigatonnes of iron and concrete and steel and copper about, is fantasy - the more so as much of the new infrastructure would have to be situated offshore.

And far worse still, "ambitiously" rationing "high heat industrial applications" means that you basically can't have much concrete. Or steel, or copper. Or carbon fibre for your wind-turbine blades. Or glass for your possible solar plants either.

No: the whole plan is plain and simple barking lunacy, based on comedy made-up numbers that signify nothing.

And yet WWF is big stuff. Reports of this type get picked up not just by the mass media but by the Intergovernmental Panel on Climate Change and used in official UN doom warnings (often much to the UN's subsequent embarrassment, as in the cases of the non-melting glaciers [7] and the non-burning rainforests [8]). WWF turns over half a billion dollars a year: not much money in some contexts, but a very big budget in marketing or PR terms. WWF can sign up the ESA, for goodness' sake. ESA astronaut André Kuipers - now in space aboard the ISS - is an official WWF ambassador, and his signature is in the front of Living Planet 2012. He writes:
Looking out of my window and watching Earth from space comes with my job as an astronaut. Nevertheless, I feel I am privileged ... I will live on the International Space Station for five months ...
Seeing Earth from space provides a unique perspective. Our planet is a beautiful and fragile place, protected only by a very thin layer of atmosphere essential for life on our planet. And seemingly large forests turned out to be small and passed by very quickly. It was this perspective, and realization, that lie behind my motivation to become a WWF ambassador.
And yet the hundreds of billions it took to build the ISS, the lesser but still enormous sums that sent Kuipers up to live aboard it - there isn't the slightest prospect that these resources would have been available in a world of the sort that WWF advocates. In a world where governments cared nothing for GDP and economic growth and surpluses, where rich nations or populations able to afford proper space programmes had been outlawed (and poor nations with small space programmes, like India, no longer got aid payments from rich ones) ... in that world, Kuipers would never have got the chance to look down on Earth. With WWF-mandated rationing on aircraft, most of his previous career as an aviation-medicine expert and airforce officer would also not have happened.

But people have a strange blind spot about WWF. They think it's still the cuddly old World Wildlife Fund (CNN does [9], anyway - and so indeed does the ESA [10]). But it's not the WWF any more, nobly trying to save the whale and the dolphin and the tiger. It has transformed into simply WWF - the initials, like those of global arms multinational BAE Systems, no longer stand for anything [11].

Today's WWF is not really about tigers and dolphins any more, though they make excellent figureheads for fundraising. Just to show how much they aren't, in fact, in step with everyone else, the organisation's activists would be very happy if the present desperate efforts to end global recession were to fail; and this just as a prelude to making you (perhaps still more) miserably poor and launching a frankly insane effort to stop the human race using fire in just 38 years - by building windmills without steel or carbon, tide barrages without concrete and solar panels without glass [12].

Think about it, next time one of your kids asks if you can sponsor a dolphin [13], or the next time you hear "WWF says ..." on the news. ®

New study says extinction fears are "alarmist"

Fears that most of the Earth's species will become extinct before they have even been discovered by science are "alarmist", according to an international study released on Friday. The study also put extinction rates at less than one percent a decade, one-fifth the level of previous estimates.

Extinction fears 'alarmist': study
by Staff WritersWellington (AFP) Jan 25, 2013




Fears that most of the Earth's species will become extinct before they have even been discovered by science are "alarmist", according to an international study released on Friday.

Researchers set out to examine estimates that there were 100 million species globally and they were dying out at a rate of five percent every decade, meaning many would disappear before scientists had a chance to discover them.
Writing in the journal Science, the researchers from New Zealand, Australia and Britain said the estimates were based on a massive over-estimation of how many species were still unknown.

They said about 1.5 million species of animals and plants had already been catalogued and statistical modelling showed the total number in existence was closer to five million than 100 million.

The study, released Friday, also put extinction rates at less than one percent a decade, one-fifth the level of previous estimates.

"Our findings are potentially good news for the conservation of global biodiversity," lead author Mark Costello from the University of Auckland said.

"Over-estimates of the number of species on Earth are self-defeating because they can make attempts to discover and conserve biodiversity appear to be hopeless. Our work suggests this is far from the case."

He said the research raised the prospect that all of Earth's species could be identified within the next 50 years, particularly since the number of taxonomists, scientists who describe new species, was increasing.

"Naming a species gives formal recognition to its existence, making its conservation far easier," Costello said.

The paper conceded that Earth was in the midst of a "human-caused mass extinction phase" but reached more optimistic conclusions on biodiversity than other researchers, such as those at the California Academy of Sciences.

In 2011, the academy said: "Despite intensive efforts to document life on Earth, scientists estimate that more than 90 percent of the species on this planet have yet to be discovered.
"In the face of large-scale habitat loss and degradation, many of these species are disappearing before we even know they exist."

Costello and his colleagues said any meeting of biologists or conservationists was "hardly complete" without similar worries being raised.

But they said the development of science in biological hotspots such as Asia and South America meant more researchers than ever were working to identify new species.
"Some people despair that most species will go extinct before they are discovered," the study said.

"However, such worries result from over-estimates of how many species may exist, beliefs that the expertise to describe species is decreasing and alarmist estimates of extinction rates."

New paper finds 'tropical species not as vulnerable to climate change extinction'

A new paper finds computer models of extinction risk failed to consider that tropical species can adapt to climate change and that the models have therefore exaggerated extinction risks. Alarmists, such as James Hansen, have claimed that 21-52% of species could become extinct due to global warming, but this new paper suggests computer models have exaggerated risks of extinction by not considering species adaptation.

  Tropical species 'not as vulnerable' to climate change extinctionby Staff WritersLondon, UK (SPX) Aug 20, 2012

Ectotherms, such as lizards and insects, have evolved a specialist physiology to flourish in a stable tropical environment.





In the face of a changing climate many species must adapt or perish. Ecologists studying evolutionary responses to climate change forecast that cold-blooded tropical species are not as vulnerable to extinction as previously thought. The study, published in the British Ecological Society's Functional Ecology, considers how fast species can evolve and adapt to compensate for a rise in temperature.

The research, carried out at the University of Zurich, was led by Dr Richard Walters, now at Reading University, alongside David Berger now at Uppsala University and Wolf Blanckenhorn, Professor of Evolutionary Ecology at Zurich.
"Forecasting the fate of any species is difficult, but it is essential for conserving biodiversity and managing natural resources," said lead author Dr Walters.

"It is believed that climate change poses a greater risk to tropical cold-blooded organisms (ectotherms), than temperate or polar species. However, as potential adaptation to climate change has not been considered in previous extinction models we tested this theory with a model forecasting evolutionary responses."

Ectotherms, such as lizards and insects, have evolved a specialist physiology to flourish in a stable tropical environment. Unlike species which live in varied habitats tropical species operate within a narrow range of temperatures, leading to increased dangers if those temperatures change.

"When its environment changes an organism can respond by moving away, adapting its physiology over time or, over generations, evolving," said Walters. "The first two responses are easy to identify, but a species' ability to adapt quick enough to respond to climate change is an important and unresolved question for ecologists."

The team explored the idea that there are also evolutionary advantages for species adapted to warmer environments. The 'hotter is better' theory suggests that species which live in high temperatures will have higher fitness, resulting from a shorter generation time. This may allow them to evolve relatively quicker than species in temperate environments.

The team sought to directly compare the increased risk of extinction associated with lower genetic variance, owing to temperature specialisation, with the lowered risk of extinction associated with a shorter generation time.

"Our model shows that the evolutionary advantage of a shorter generation time should compensate species which are adapted to narrow temperature ranges," said Walters. "We forecast that the relative risk of extinction is likely to be lower for tropical species than temperate ones."

"The tropics are home to the greatest biodiversity on earth, so it imperative that the risk of extinction caused by climate change is understood," concluded Walters. "While many questions remain, our theoretical predictions suggest tropical species may not be as vulnerable to climate warming as previously thought."

New book says Earth is too cold for maximum development of the biosphere

A new book by Professor of Earth Sciences Toby Tyrell "finds that the Earth is actually too cold for the maximum development of the biosphere." A review of the book published today in Nature Climate Change states, "Using net primary production and biodiversity as metrics, Tyrell finds that the Earth is actually too cold for the maximum development of the biosphere" and "the climate and biogeochemical cycles of the Holocene [the past ~11,000 years] have been unusually stable."

On Gaia: A Critical Investigation of the Relationship between Life and Earth

Gaia, the brainchild of James Lovelock, was born in 1972. The historical constancy of Earth's chemical conditions and climate seemed just too much for chance alone. In Gaia it is postulated that the Earth's conditions were determined by the biosphere and regulated for the further benefit of life's persistence and activity. Gaia has motivated a huge number of biogeochemists to think about ecology on the planetary scale, and to examine what causes the movement and transformation of elements in global cycles. The theory has survived withering criticism and numerous international conventions — some to extend its reach and others to bandage a wounded Gaia with modifications and caveats. Even now, when students read Lovelock's first book on Gaia they engage with his insights enthusiastically.
In this book, Toby Tyrell — a professor of Earth science at the University of Southampton — offers a systematic, dispassionate, retrospective examination of Gaia. It will be hard to ignore the flaws in Gaia, illustrated nicely in a table showing the success and failure of Gaia relative to some alternative theories based on the geosciences and coevolution. In the face of data, Gaia fails in its idea that the Earth is held at conditions optimal for life. Using net primary production and biodiversity as metrics, Tyrell finds that the Earth is actually too cold for the maximum development of the biosphere. Gaia also fails in its postulate that the Earth is held at relatively stable conditions. True, the climate and biogeochemical cycles of the Holocene [the past ~11,000 years] have been unusually stable, but over longer periods of time the biosphere has been buffeted by events that have dealt it quite a blow. What is remarkable is that life persisted at all — a statement of the power of evolution to rebuild the biosphere everywhere as long as life has endured somewhere...

New paper finds global warming is not a threat to humanity & GDP will be highest under the warmest scenario

A new paper published in Wiley Interdisciplinary Reviews: Climate Change "challenges claims that global warming outranks other threats facing humanity through the foreseeable future (assumed to be 2085–2100)." According to the author,
"World Health Organization and British government-sponsored global impact studies indicate that, relative to other factors, global warming's impact on key determinants of human and environmental well-being should be small through 2085 even under the warmest Intergovernmental Panel on Climate Change (IPCC) scenario. Specifically, over 20 other health risks currently contribute more to death and disease worldwide than global warming."
Furthermore,
"warming should reduce future global population at risk of water stress, and pressures on ecosystems and biodiversity (by increasing net biome productivity and decreasing habitat conversion)."

"For both developing and industrialized countries, net GDP per capita—albeit an imperfect surrogate for human well-being—should be (1) double the current US level by 2100 under the warmest scenario, and (2) lowest under the poorest IPCC scenario but highest under the warmest scenario through 2200. The warmest world, being wealthier, should also have greater capacity to address any problem, including warming. Therefore, other problems and, specifically, lowered economic development are greater threats to humanity than global warming."


Is climate change the number one threat to humanity?

Abstract:


This paper challenges claims that global warming outranks other threats facing humanity through the foreseeable future (assumed to be 2085–2100). World Health Organization and British government-sponsored global impact studies indicate that, relative to other factors, global warming's impact on key determinants of human and environmental well-being should be small through 2085 even under the warmest Intergovernmental Panel on Climate Change (IPCC) scenario. Specifically, over 20 other health risks currently contribute more to death and disease worldwide than global warming. Through 2085, only 13% of mortality from hunger, malaria, and extreme weather events (including coastal flooding from sea level rise) should be from warming. Moreover, warming should reduce future global population at risk of water stress, and pressures on ecosystems and biodiversity (by increasing net biome productivity and decreasing habitat conversion). That warming is not fundamental to human well-being is reinforced by lower bound estimates of net gross domestic product (GDP) per capita. This measure adjusts GDP downward to account for damages from warming due to market, health, and environmental impacts, and risk of catastrophe. For both developing and industrialized countries, net GDP per capita—albeit an imperfect surrogate for human well-being—should be (1) double the current US level by 2100 under the warmest scenario, and (2) lowest under the poorest IPCC scenario but highest under the warmest scenario through 2200. The warmest world, being wealthier, should also have greater capacity to address any problem, including warming. Therefore, other problems and, specifically, lowered economic development are greater threats to humanity than global warming. WIREs Clim Change 2012. doi: 10.1002/wcc.194
