Plant Growth Database (28 October 2016)
Our latest posting of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for well-fertilized barley plants (cv, Bambina) grown in controlled environment chambers under a reduced (33% less) supply of water (Schmid et al., 2016).

Continental Energy Storage in CMIP5 Climate Change Simulations (27 October 2016)
The current generation of GCMs does not perform well in calculating the change in the continental component of heat storage in Earth's terrestrial surfaces...

Searching for a Greenhouse Gas Signal in Guatemalan Drought Records (26 October 2016)
The authors of this study state that "the expected signal of anthropogenic influence on the precipitation regime of the region has not unambiguously emerged," which is the politically-correct way of saying that their observations do not align with model projections for this region...

Rising CO2 Enhances the Growth of Eighteen Blackgram Genotypes (25 October 2016)
Five morphological, six dry weight and eight yield traits examined by the authors of this study were found to benefit from higher levels of atmospheric CO2...

The Rapid Evolutionary Response of an Important Soil Invertebrate (24 October 2016)
Although annelid worms may currently not move from place to place very fast, they need not worry too much about it, as they can successfully evolve to be able to meet the need to do so...

A Portrayal of Inter-El Niño Variability in CMIP5 Climate Models (21 October 2016)
The result reveals another real-world example of the difficulty of mankind's ability to reduce one of nature's unique climatic phenomena to a set of mathematical equations that would have the ability to foretell the future...

Plant Growth Database (21 October 2016)
Our latest posting of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Wheat (Xu et al., 2015). To access the entire database, click here.

How High-Arctic Reindeer Respond to Extreme Weather Events (20 October 2016)
Like what might be expected of any such noble four-legged species, when the going gets tough, the tough get going...

Malaria Transmission: Helped or Hindered in a Warming World? (19 October 2016)

Extreme Precipitation Events As Represented in CMIP5 Models (18 October 2016)
Once again, today's best climate models are demonstrated to still have a considerable way to go before they can be used to adequately project the frequency and magnitude of weather events of this nature...

Atmospheric CO2 Enrichment Helps Plants to Deal with Drought (17 October 2016)
Another experiment demonstrates that the unwanted negative consequences of a common environmental stressor - which is often experienced throughout the world - may be largely thwarted by the ongoing rise in the air's CO2 content...

The Diversity and Abundance of Reef Fish Help to Sustain Them (14 October 2016)
Nature, it would appear, best helps those species of reef fish that help themselves...

Modelling Both Water and Ice Clouds: How Goes the Worthy Effort? (13 October 2016)

Plant Growth Database (13 October 2016)
Our latest posting of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Mango (Schaffer et al., 1997). To access the entire database, click here.

Fifty-five Years of Trends of High-Impact Weather Events in China (12 October 2016)
Climate alarmists continually and contentiously claim that rising atmospheric CO2 concentrations lead to more frequent and serious weather events throughout the world. But is this really the case?...

A team of 17 European researchers comes together to actually show experimentally how it is done...

Plant Root Loss to Herbivores Reduced by Aerial CO2 Enrichment (10 October 2016)
Atmospheric CO2 enrichment sometimes has its greatest positive impact belowground on plant root growth and maintenance...

Problems in CMIP5 Modeling of Atlantic Multi-Decadal Variability (7 October 2016)
As up-to-date as they are, and as highly hyped as they are, CMIP5 models still fall short - and way short in this instance - in properly modeling multi-decadal fluctuations of the North Atlantic Ocean and their impacts on winter climate...

Outbreaks of Insects and the Severity of Subsequent Forest Fires (6 October 2016)
A new study suggests that outbreaks of vegetation-devouring insects can actually promote something as beneficial as the reduction of the severity of regional forest fires...

Effects of Night Warming on Leaves and Roots of Coniferous Trees (5 October 2016)
Even in the dead of night, warming - whether CO2-induced or otherwise - has the ability to produce a number of very positive tree responses...

Plant Growth Database (5 October 2016)

Current Plant Distributions Fail to Represent their Potential Ranges (4 October 2016)
Why is this fact so significant? Because certain climate modelers suggest that many plants are currently at the thermal limits of their geographical ranges, when studies such as the one reviewed here suggest otherwise. And that is good news for the biosphere...
