Mid- and High-Latitude Forests Respond to Environmental Change (18 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 (18 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...

The Diverse Impacts of Ocean Acidification on Marine N2 Fixers (15 October 2014)
They range from negative to neutral to positive. Guess which one predominates...

Impacts of Warming and Cooling Trends on Swedish Alpine Flora (14 October 2014)
By what means and how well have the plants dealt with these two climatic challenges?...

Some Incompatibilities of Global and Regional Climate Models (14 October 2014)
Regional- to local-scale predictions of GCMs can often be misleading; and corrections imposed by RCM downscaling can also be misleading...

Modelling Features of the Indian Summer Monsoon via ECHAM5 (14 October 2014)
This study illustrates the fact that in spite of all that the world's climate modelers have accomplished in many different areas, they have only just begun to traverse the long-and-winding road that leads to ultimate climate modeling success; for as they learn ever more about the various facets of Earth's climatic system, they begin to discover there is even more out there in the 'great beyond' that they must successfully reduce to functionally-correct mathematical expressions that can be incorporated into their computer-driven models...

The Impacts of Hot Days with Night Warming on Small Insect Pests (10 October 2014)
The take-home message of this new work is that although many average or mean temperature models predict increasing pest outbreaks in a warming world, the results of Zhao et al. suggest that "outbreaks of some species might decrease due to the effects of night warming on population dynamics." But try getting a climate alarmist to admit that!...

Plant Growth Database (10 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 Mung Bean (Mishra and Agrawal, 2014)...

Impacts of Future pH Reductions on the Early Life of Reef Corals (9 October 2014)
Wave upon wave of new reef coral "youngsters" might well have a significant period of time during which they - and their descendants' descendants - could conceivably better learn to cope with slowly declining-pH seawater...

Six Decades of Northeast Atlantic Phytoplankton Productivity (9 October 2014)
Despite what climate alarmists refer to as an unprecedented rise in temperatures and CO2 over the past few decades, phytoplankton of the Northeast Atlantic are no worse for the wear. In fact, truth be told, they are faring far better!...
