Effects of Elevated CO2 and Heat Stress on Tomato Seedlings
(29 June 2020)
Higher levels of CO2 impacted genes associated with hydrogen peroxide accumulation that helped decrease stomatal aperture, which ultimately "played a crucial role in elevated CO2-induced heat tolerance by maintaining a balance between water retention and heat loss"...
Transgenerational Plasticity of Marine Bivalves to Ocean Acidification (26 June 2020)
A recent review paper examining the impacts of ocean acidification on five bivalve species reveals that each species experienced positive transgenerational responses to an elevated pCO2 scenario projected for the year 2100...

Interactive Effects of CO2 and Temperature on Cassava (24 June 2020)
This study puts to rest alarmist concerns that cassava plants will contain greater (and potentially deadly) concentrations of cyanide in the future because of rising atmospheric CO2....

The Response of Two Maize Varieties to CO2 Enrichment
(22 June 2020)
Climate alarmists have long claimed that C4 plants like maize are unresponsive to CO2 enrichment, yet more and more research -- like that observed here -- is falsifying that narrative, showing that yields of many C4 crops will likely experience significant gains in the future...
Long-term Carbon Accumulation Rates of Two Alaska Peatlands (19 June 2020)
Global warming alarmists contend rising temperatures should be degrading permafrost peatlands and releasing long-sequestered carbon back into the atmosphere. Real-world data based on the work of Taylor et al. reveal the opposite is occurring -- carbon accumulation rates have increased three-fold during the era of modern warming...

Plant Growth Database (18 June 2020)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for White Mangrove (Jacotot et al., 2018). To access the entire database, click here.

A 423-year Moisture Reconstruction for San Luis Potosi, Mexico
(17 June 2020)
In examining the record, its observed cyclic nature, coupled with what appears to be an absence of any trend in the data, suggests that rising concentrations of atmospheric CO2 have had no measurable impact on droughts or pluvials in the region...

No Response of a Toxic Algae to Ocean Acidification and Warming (15 June 2020)
Neither increased temperature nor elevated pCO2 seawater had an effect on the growth of this harmful microalgae, either alone or in combination...

Gross Primary Productivity Trends in China (1982-2015)
(12 June 2020)
Vegetation all across China is in the midst of a long period of great productivity gains and those gains are primarily linked to the very factor climate alarmists contend should be causing vegetative dieback, i.e., rising temperature. Climate alarmists couldn't be more wrong!...

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

Combined Effects of Elevated CO2 and Temperature on Eastern Cottonwood
(10 June 2020)
Higher levels of both CO2 and temperature initiate differential expression of genes that act to improve photosynthesis and growth of this poplar species...

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

Observed vs Predicted Trends in Northern Hemisphere Snow Cover
(8 June 2020)
A detailed analysis of trends in Northern Hemisphere snow cover over the period 1967-2018 reveal climate models have a long way to go to accurately predict this parameter...

The Combined Impacts of CO2 Fertilization and Nitrogen Supply on Wheat
(5 June 2020)
The results of this study suggests that protein and other micronutrient declines that are sometimes observed in crops at higher CO2 concentrations can be overcome by providing the right balance of nitrogen-supplied fertilizer...
