The Importance of the Oceans and Topography in Climate Simulations (19 Apr 2011)

Wilson et al. (2010) use a coupled atmosphere-ocean general circulation model to examine the impact of mountains and the oceans in simulating the regular occurrence of our planet’s cyclonic storm systems. They find that in order to achieve more faithful model simulations of climate, a dynamic ocean and the proper representation of topography are crucial ... Read More

Growth Response of Radish to Super Atmospheric CO2 Enrichment (19 Apr 2011)

How high can the plant’s growth rate possibly rise??? ... Read More

The Climatic History of the European North Atlantic Seaboard (19 Apr 2011)

“Since tree-limits in Scandinavia or elsewhere in the world have not reestablished at their Medieval levels, it is still possible that today’s climate, despite centennial net warming, is within its natural limits” ... Read More

Central Pacific El Niño Events (19 Apr 2011)

The authors of this study conclude that “we cannot exclude the possibility that an increasing of occurrence frequency of CP El Niño during recent decades in the observation could be a part of natural variability in the tropical climate system” ... Read More

A New-and-Improved 457-Year History of ENSO Variability (19 Apr 2011)

Contrary to the projections of many climate models that have been made over a period of many years, Braganza et al. were unable to discern any unusual behavior in ENSO activity during the transition from what was the coldest period of the current interglacial to just before what the world’s climate alarmists claim was the warmest period of the past two millennia, which finding raises further questions about the validity of the model projections ...

Nitrous Oxide (N2O) Fluxes from Temperate Grasslands in a Warmer, Wetter and CO2-Enriched World (19 Apr 2011)

How do the three oft-predicted environmental changes impact natural emissions of the powerful greenhouse gas?. ... Read More

Regional Climate Change: How Well to the IPCC Models Really Perform? (20 Apr 2011)

It is well known that climate models have difficulty in not only projecting future climate, but in replicating the past climate. In addition to inadequate model physics or a lack of data, there is a naturally inherent uncertainty in models that fluid dynamicists generically call chaos. One way to overcome these problems is to run the models many times and generate a range of possibilities called scenarios. Such a strategy would be useful if models could replicate climate adequately. Anagnostopoulos et al. (2010) demonstrate using a statistical approach that dynamic modeling alone should not be used to project future climate ... Read More

Catastrophic Superstorms of the French Mediterranean Coast (20 Apr 2011)

The two periods of most frequent superstorm strikes in the Aigues-Mortes Gulf coincide with two of the coldest periods in Europe during the late Holocene ... Read More

Aquatic Herbivores in a CO2-Enriched World of the Future (20 Apr 2011)

Will they fare as well as they do today? ... Read More

The Impact of Warming on Fungal Epidemics in Lakes (20 Apr 2011)

The authors’ findings present “a scenario that runs counter to the general expectation of a ‘warmer hence sicker world’” ... Read More

A Twentieth-Century Rainfall History of India (20 Apr 2011)

Contrary to the implications of global climate models employed by the IPCC, the global warming of the past century has not led to any significant concomitant change in the mean annual rainfall of all of India or that of any of its four sub-regions ... Read More

How a Long-Term CO2-Induced Increase in Forest Productivity is Maintained on a Nitrogen-Impoverished Soil (20 Apr 2011)

The key to the phenomenon may reside in the type of fungi colonizing the trees’ roots ... Read More
