A Transcriptome-based Analysis of the Interactive Effects of Elevated CO2 and Herbivory Attack on Grapevine (22 August 2019)
Grapevine leaves growing in a CO2-enrichment environment and subjected to herbivore attack from the European grapevine moth show a higher-fold change in gene expression patterns related to plant defense mechanisms than leaves under similar attack and growing in an ambient CO2 environment...

A 2000-Year History of Temperature on the Southern Tibetan Plateau (21 August 2019)
There have been multiple times during the past two millennia when temperatures were warmer than present, including the 400 year period from 850-1250 AD, despite their being 50% less CO2 in the atmosphere than there is today...

Why CO2 is Not the Control Knob of Global Temperature and Observational Proof it is Not Causing Dangerous Warming (20 August 2019)
There is much debate on whether or not the modern increase in atmospheric CO2 has caused, or is presently causing, dangerous global warming, warming so severe that it is threatening life all across the planet. Read this article posted on our sister website the Institute for the Human Environment to find out why a rise in the atmospheric trace gas should not be feared...

Plant Growth Database (20 August 2019)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Red Ironbark (Duan et al., 2018). To access the entire database, click here.

Elevated CO2 Improves the Growth of Two Mangrove Tree Species (19 August 2019)
According to the scientists who conducted this study, "future climate changes may enhance the productivity of mangrove seedlings by increasing their growth, which may in turn increase the carbon storage potential of mangroves"...

Elevated Temperature and CO2 Reduce Potato Virus Y Transmission Rates (16 August 2019)
Rising levels of atmospheric CO2 and a warmer climate will significantly reduce aphid transmission rates of potato virus Y to Nicotiana benthamiana...

Plant Growth Database (15 August 2019)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Wheat (Macabuhay et al., 2018; grain yield). To access the entire database, click here.

Grassland Productivity Responses to Elevated CO2 (14 August 2019)
A 250 ppm increase in atmospheric CO2 boosted the aboveground net primary productivity of native Texas grasslands by 49%, 84% and 38% that were grown on sandy loam, silty clay and clay soil type treatments, respectively...

Plant Growth Database (13 August 2019)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Rice (Zhao et al., 2018). To access the entire database, click here.

The Interactive Effects of CO2, Phosphorus Supply and Cyanobacterial Inoculation on Cowpea (12 August 2019)
A small, 150 ppm, increase in atmospheric CO2 is sufficient to raise yields of this important leguminous crop by approximately 26 percent. And those yield improvements can be augmented further via application of soil phosphorus and cyanobacterial inoculation...

Plant Growth Database (9 August 2019)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Flat-topped Bogmoss (Newman et al., 2018). To access the entire database, click here.

The Positive Impact of Fossil Fuel Use on Terrestrial Net Primary Productivity (8 August 2019)
Global terrestrial net primary productivity increased from 56.2 to 66.0 Pg C/year since 1901 and fossil fuel combustion was the reason for that improvement...

Real-world Evidence that CO2 Emissions and Fossil Energy Enhance the Human Environment (2 August 2019)
Watch a video or read the text of a presentation given by Dr. Craig Idso at the 13th International Climate Conference.

Plant Growth Database (2 August 2019)

The Response of Four Woody Ecosystems to Atmospheric CO2 Enrichment (29 July 2019)
Based on an analysis of four long term (decade-long) CO2 enrichment experiments (to 550-700 ppm), the authors of this study calculated a decadal increase in ecosystem biomass due to CO2 of 29%, whereas the net primary productivity changed by a more modest 22.9%...
