CMIP5 Modeling of Extreme Precipitation in Europe

Published September 20, 2013

Van Haren et al. conclude their report by declaring that “it is important that we improve our understanding of circulation changes, in particular related to the cause of the apparent mismatch between observed and modeled circulation trends over the past century,” citing Haarsma et al. (2013); for if the models don’t improve in this regard, neither will their precipitation predictions improve… Read More

Climate Change Reconsidered II- Physical Science Is Released
On September 17, the Nongovernmental International Panel on Climate Change released Climate Change Reconsidered II: Physical Science, more than 1,000 pages documenting the evidence that anthropogenic carbon dioxide emissions are not causing a global warming crisis. The report contains literally thousands of citations to the peer-reviewed literature. A downloadable PDF is available online at climatechangereconsidered.org, where you will also find previous volumes in the series, media coverage of the new volume’s release, and more.

Feeding China’s Giant Pandas: Is There a Role for Rising CO2? (17 Sep 2013)
The ultimate conclusion of this study is that rising temperatures and elevated CO2 “will be beneficial” for dwarf bamboo that the pandas feed upon, as it will lead to the production of more equally-nutritious dwarf bamboo tissue… Read More

Evolutionary Adaptation to Rising Atmospheric CO2 Concentration (17 Sep 2013)
The authors of this new study “were able to reveal a dimension of plant-environment feedbacks, which is currently insufficiently investigated and described for the response of plants to future CO2 concentrations,” and that dimension reveals a promising future for Earth’s plant life… Read More

CMIP5 Earth System Models: Trying to Model Soil Carbon Stocks (17 Sep 2013)
The results of this analysis reveal that only some Earth System Models “simulated soil carbon stocks consistent with empirical estimates at the global and biome scales” and that all of the models “had difficulty representing soil carbon at the 1° scale,” indicating that “despite similar overall structures, the models do not agree well among themselves or with empirical data on the global distribution of soil carbon”… Read More

Epigenetic Phenomena May Help Trees Cope with Global Warming (18 Sep 2013)
It seems that the deeper we peer into the internal workings of Earth’s plant life, the more we learn about the wealth of sensory, evaluative and decision-making capabilities they appear to possess, which is likely why they are still with us here today … and why we can expect them to be here tomorrow as well… Read More

The Repetitive Bleaching of Corals: Can Any Good Come from It? (18 Sep 2013)
In spite of the presence of similar thermal stress, the authors of this report found that “the bleaching intensity was lower in 2007 (25-49%) than in 2002 (39-72%),” and that “the response to elevated temperature was delayed in the latter year,” adding that “it is likely that the observed decrease in stress response was the result of acclimatization of the coral/algal holobionts … or an influx of thermo-tolerant colonies between 2002 and 2007″… Read More

Purple Sea Urchins: Primed for Rapid Evolution in Acidifying Seas (18 Sep 2013)
The results of this study “demonstrate the capacity for rapid evolution in the face of ocean acidification and show that standing genetic variation could be a reservoir of resilience to climate change in this coastal upwelling ecosystem”… Read More
