Plant Growth Database (18 February 2020)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Grey Mangrove (Jacotot et al., 2019). To access the entire database, click here.
Testing for a Temperature Effect on Homicides in New York and London (17 February 2020)
When proper methods are utilized, there is no evidence of a relationship between temperature and homicides over the period 1895-2015...

Observed Rates of Arctic Warming Fail to Validate Model-based Projections
(14 February 2020)
An important new study has determined that climate models are over-predicting rates of Arctic warming based on an analysis between observed and model-predicted temperatures in this key far north region. At present, the discrepancy amounts to a 67% over-prediction in warming that is increasing every year. Such failure of the models is yet another reason to abandon policies that call for the regulation of CO2 emissions...

Plant Growth Database (13 February 2020)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Wheat (Li et al., 2019). To access the entire database, click here.

Elevated CO2 Improves the Growth, Yield and Water Use Efficiency of Two Grape Cultivars
(12 February 2020)
It is quite remarkable that a small (79 ppm) increase in atmospheric CO2 is capable of providing significant growth and yield-related benefits to the viticulture industry...
Rising CO2 and Increased N Fertilization Improve Maize Defense of the Asian Corn Borer (11 February 2020)
As the air's CO2 concentration rises in the years and decades ahead, farmers who utilize N fertilization in the production of maize will promote its resistance to the Asian corn borer crop pest. And that will translate to greater yields to be consumed by an ever-increasing planetary population...

Plant Growth Database (11 February 2020)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Soybean (Bencke-Malato et al., 2019). To access the entire database, click here.

Elevated CO2 Improves Phytoremediation of Cadmium Contaminated Soils
(10 February 2020)
Higher levels of atmospheric CO2 increased the amount of Cadmium uptake by an Asian herb by as much as 261%...

Plant Growth Database (6 February 2020)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Andiroba (Oliveira and Marenco, 2019b). To access the entire database, click here.
Addendum to a Research Report Challenging the EPA's CO2 Endangerment Finding (5 February 2020)
A June 2017 Research Report provided ample evidence that the Global Average Surface Temperature (GAST) dataset was invalidated for use in climate modelling and climate change policy analysis purposes, such as the EPA's 2009 CO2 Endangerment Finding. However, there was one key science argument the original report did not make, which is made in this newly-released Addendum. Read the original 2017 report here.

Five Decades of Severe Storm and Hail Days in the Tibetan Plateau
(5 February 2020)
Despite significant global warming that has occurred in this region since the 1950s, the frequency of these two severe weather events has declined, and it stark fashion. And that observation led the authors of this study to conclude that "global warming is likely to cause a decrease in the conditions required for severe thunderstorm and hail formation in the Tibetan Plateau over the next century"...

Plant Growth Database (4 February 2020)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Rice (Hasegawa et al., 2019). To access the entire database, click here.

A Recent Analysis of Ecosystem Water Use Efficiency Trends in an Old-growth Forest
(3 February 2020)
Water use efficiency increased by approximately 26% over the 18-year period 1998-2015, which increase was largely driven by rising levels of atmospheric CO2...

Plant Growth Database (31 January 2020)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Blackeyed Pea (Dey et al., 2019). To access the entire database, click here.
Yellowtail Kingfish Response to Ocean Acidification and Warming (30 January 2020)
A new study investigating the effects of ocean acidification and warming on the organ health and development of larval kingfish finds no measurable impacts. Instead this species is determined to be robust to these so-called "twin environmental evils"...
