What We Know About Effects of Climate Change on Amphibians (24 October 2014)
It's actually not all that much, yet "evidence that climate change is directly contributing to amphibian declines is weak"...

The Response of a Coral Reef Sea Urchin to Ocean Acidification (24 October 2014)
A new mesocosm study probes the subject and effectively dismantles metabolism-based concerns for this marine species under conditions of elevated CO2...

Two Thousand Years of Cyclical Drought in New Mexico, USA (24 October 2014)
Solar variations appear to be the primary cause of periods of drought in northern New Mexico over the past two millennia. Inferring they are caused by anything else, including CO2-induced global warming, is a far-fetched stretch...

Plant Growth Database (24 October 2014)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Bamboo (Grombone-Guaratini et al., 2013)...

Effects of CO2 on the Growth & Flavonoids of Two Medicinal Plants (22 October 2014)
The yield and pharmaceutical quality of Scutellaria species can be enhanced "with controlled environment production and CO2 enrichment"...

Why 2014 Won’t Be the Warmest Year on Record (21 October 2014)
Much is being made of the “global” surface thermometer data, which three-quarters the way through 2014 is now suggesting the global average this year will be the warmest in the modern instrumental record. Dr. Roy Spencer explains why he feels this is wrong...

Sea Level Rates-of-Rise Along Europe's North Sea Coastline (21 October 2014)
Have they accelerated as the air's CO2 concentration has continued its upward climb?...

Gene Expression Plasticity Evolution in Threespine Stickleback Fish (21 October 2014)
A new study finds extremely compelling support for it, and that is encouraging news for those concerned about animal range expansions or shifts caused by climate change...

Mid- and High-Latitude Forests Respond to Environmental Change (20 October 2014)
To "reduce the uncertainties in predicting future carbon dynamics in forest ecosystems, land surface models should not only consider land-use history, but also account for key physiological processes governing the fate of carbon sequestration in forest ecosystems, such as the effects of CO2 fertilization, nitrogen deposition, and climate warming on vegetation growth."...

Historical Diurnal Temperature Range Trends in CMIP5 Models (20 October 2014)
It would seem that "ubiquitous model deficiencies in cloud cover and land surface processes that impact the accurate simulation of regional minimum or maximum temperature changes" are likely responsible for the inability of the models to simulate real-world DTR observations...

Effects of Elevated CO2 on Eucalypt Growth and Leaf-Spot Severity (18 October 2014)
In going from the lowest to the highest atmospheric CO2 concentrations, shoot dry weight increased by 47% and root dry weight by 24%, while leaf-spot disease incidence declined by 36% and its severity by 57%...

Twentieth Century Changes in California's Sierra Nevada Forests (18 October 2014)
If the CO2 emitted to the atmosphere by the burning of fossil fuels over the past century or so has been having an effect on the forests of California's Sierra Nevada, that effect has been not only positive, but hugely positive...

CMIP5 Simulations of the North American Monsoon System (17 October 2014)
In how many ways are the current best models still falling short of reality?...

Plant Growth Database (17 October 2014)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Garden Bean (Bunce, 2014)...

Alleviating Phosphorus Limitations in a Future Acidified Ocean (15 October 2014)
Once again, we have another example of a marine organism that will likely benefit from so-called ocean acidification, even in the face of an important resource limitation...
