Three Decades of Aboveground Net Primary Productivity on the Eurasian Steppe (29 December 2017)
Over the period 1982-2013, the productivity of this vast grassland has increased by 16 percent despite all the natural and anthropogenic pressures to the contrary, once again revealing the great greening of the planet that has been observed in recent decades all across the Earth...

Recent Stability of Bird Populations in the Pacific Northwest, USA (28 December 2017)
Climate alarmists and their models claim that these birds should be suffering the effects of CO2-induced climate change. Real-world data, however, indicate otherwise...

Elevated CO2-induced Increases in both Rice and Maize (26 December 2017)
The growth and yield of both rice and maize, a C3 and C4 crop, respectively, respond positively to increases in the air's CO2 content...

Plant Growth Database (25 December 2017)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Concord Grape (da Silva et al., 2017). To access the entire database, click here.

A 341-year Temperature Reconstruction for Southwest China (23 December 2017)
In a location that is projected to show large-scale and rapid warming in response to increasing emissions of CO2 into the atmosphere, real-world data show that warming is just not happening...

CO2 Fertilization Negates the Negative Impacts of Climate Change on Brazilian Coffee Yield (21 December 2017)
Modelers and policy makers the world over would be wise to start embracing the benefits of atmospheric CO2 enrichment and include them in all future studies that predict the impacts of climate change on agricultural yields, and correspondingly, food security...

A Five-century Streamflow Reconstruction from China (20 December 2017)
There appears to be nothing unusual, unnatural or unprecedented about this streamflow record, which appears to have regularly oscillated between periods of above- and below-average flow, keeping within the realm of natural variability...

Plant Growth Database (19 December 2017)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Cotton (Zhang et al., 2017). To access the entire database, click here.

A Two-Century Reconstruction of Vapor Pressure Deficit and its Impact on a Boreal Forest (18 December 2017)
Climate warming appears to have not impacted the vapor pressure deficit; nor has it led to drought-induced reductions in forest growth, as these authors initially hypothesized...

The Interactive Effects of Elevated CO2, Phosphorus and Cyanobacteria Seed Inoculation on Mungbean (15 December 2017)
The enhanced growth and yield of mungbean at higher levels of atmospheric CO2 can be further augmented by the application of phosphorus and cyanobacteria seed inoculation...

The Response of Two Branching Corals to Ocean Acidification (14 December 2017)
It appears that they maintain an ability to phenotypically adapt so as to cope with projected declines in oceanic pH...

Elevated CO2 Reduces the Growth-inhibiting Impacts of Potassium Deficiency on Soybean (13 December 2017)
Soybean plants grown in areas of the world that are experiencing K deficiency will benefit considerably from the ongoing rise in the air's CO2 content...

Declining Trends in Recent Australian Fire Activity (12 December 2017)
Contrary to alarmist projections, the number of fires in Australia is on the decline...

Growth and Water Use Benefits for Rice Under Enhanced CO2 Conditions (8 December 2017)
In the future, not only will the biomass of rice increase as the air's CO2 concentration rises, but it will produce more biomass per unit of water applied, which enhanced growth and water savings are both win-wins for the agricultural sector...

Recent Trends in Regional Sea Level Rise Near Taiwan (7 December 2017)
Does the trend support climate alarmist concerns of a dangerous acceleration in sea level rise? In a word, NO!...

The Relationship Between CO2-induced Plant Growth Stimulation and Nitrogen Acquisition (6 December 2017)
The progressive nitrogen limitation (PNL) hypothesis has long been championed by climate alarmists, who claim that low concentrations of soil nitrogen will curtail the ability of the productivity-enhancing effect of rising atmospheric CO2 concentrations to maintain increased plant growth and ecosystem carbon sequestration rates over the long term. Results from an important meta-analysis, however, reveal such limitation is not taking place...

Plant Growth Database (5 December 2017)

Ocean Acidification is Not Detrimental to Two Macroalgae Species (4 December 2017)
A new study of the early life of two kelp species reveals that a reduction in seawater pH (i.e., ocean acidification) will improve their growth and development...

The Attenuation of Corn Yield Sensitivity to Rising Temperatures (1 December 2017)
Statistical analyses reveal that the decline in corn yields due to a 1 °C rise in temperature has lessened with time: from a 7% decline to a nonsignificant 2.4% reduction over past 30 years...
