Among the many climate-alarmist fears of CO2-induced global warming is the concern that the productivity of the biosphere will decline if global temperatures rise to the extent predicted by computer models. Because of such concern, several researchers have investigated the relationship between temperature, atmospheric CO2, and biospheric productivity across a range of spatial and temporal scales. In this review we examine what has been learned about the subject for locations in Europe.
The recent rise in atmospheric CO2 may already have had significant impacts on productivity, structure and water relations of sclerophyllous shrub vegetation, which tended to offset the detrimental effects of climate change in the region.
In contrast to model predictions, no single alpine plant species has become extinct, neither in Scandinavia nor in any other part of the world in response to climate warming over the past century.
Considering the results in their totality, the Dutch and Spanish researchers concluded that, over the last two decades of the 20th century, "Europe as a whole has a tendency to greening," and much of it is "seeing an increase in its wood land proportion."
In considering each of the studies conducted in Europe that are listed above, we note that within the context of today's obsession with the ongoing rise in the atmosphere's CO2 content, as well as the many environmental catastrophes it has been predicted to produce, the overwhelmingly positive results that have been obtained are truly remarkable. And this assessment is even more remarkable in light of the fact that the world's climate alarmists claim the warming of the past quarter-century was unprecedented over the last two millennia or more, and that this phenomenon is the greatest threat ever to be faced by the planet. Apparently, the plants of Europe just don't understand the seriousness of the situation.
