An About-face on the Impact of Landcover Change on Historic Temperatures (18 January 2019)
The IPCC has incorrectly assumed the magnitude and even sign of the temperature forcing associated with historical landcover change. Consequently, one is left wondering just how much of the 20th century warming is really due to rising atmospheric CO2 and other greenhouse gases once the correct impact of landcover change is factored in...

The Interaction of Elevated CO2 and Drought on Canola (17 January 2019)
Under well-watered or drought conditions, elevated CO2 induces a positive enhancement to canola seed yield, which in the case of one of the two cultivars examined in this study, is large enough to fully ameliorate the negative impacts of drought on this parameter...

The Impacts of a Warming Climate on Human Health in Ningbo, China (16 January 2019)
Annual years of life lost (YLL) due to cold weather for the elderly are 16.77 times higher than those lost from hot weather. And future projections indicate that a warming climate will yield a net savings in YLL from 7 to 27%, depending on the future greenhouse gas emissions scenario used...

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

Impacts of Elevated CO2 on a Perennial Grass Species During Drought (14 January 2019)
The results of this study reveal that future increases in atmospheric CO2 concentrations will likely benefit creeping bentgrass and other stoloniferous plant species, especially during times of drought...

Reef-dwelling Fish Resilience Despite Widespread Coral Bleaching (11 January 2019)
A new study shows fish are able to persist at bleached locations devoid of live coral and/or inundated with cyanobacteria despite previous projections to the contrary...

More Evidence for the Positive Impacts of Elevated CO2 on Wheat (10 January 2019)
Atmospheric CO2 enrichment improves wheat growth and yield, even when growing conditions are less than ideal. Such is the conclusion gleaned from data presented in this new study, where elevated CO2 still elicited positive growth responses despite three simulated heat waves with temperatures of 7-15°C above normal...

A Two-century Reconstruction of Summer Temperatures on the Southeastern Tibetan Plateau (9 January 2019)
Of the twelve extremely warm years identified in this record, eleven occurred in the 1800s, leaving only one such event over the past 100-plus years!...

Plant Growth Database (8 January 2019)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Thale Cress (Dhami et al., 2018). To access the entire database, click here.

Elevated CO2 and the Growth Response of Three Rice Cultivars (7 January 2019)
Elevated CO2 approximately doubled the tiller number, leaf number, leaf area and fresh biomass of the rice plants examined in this study...

The Interactive Effects of Temperature, Ammonium and Ocean Acidification on a Coastal Seagrass (4 January 2019)
Based on their findings, the authors of this study say "it seems that climate change and to some extent nutrient enrichment in coastal areas may not be so detrimental to seagrasses as previously believed"...

Temperature-induced Cardiovascular Disease Deaths in Iran (3 January 2019)
The risk of death due to cardiovascular-related diseases is more severe in cold versus warm weather...

Elevated CO2 and Weed Herbicide Effectiveness (2 January 2019)
Not only does elevated CO2 tend to not enhance weed biomass, it does not seem to alter herbicide effectiveness either. And that is good news for those concerned about the future management and control of weeds...

Plant Growth Database (1 January 2019)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Basil (Al Jaouni et al., 2018). To access the entire database, click here.

The Interactive Effects of Elevated CO2 and Drought on Cassava (31 December 2018)
Under well-watered conditions the tuberous root production of cassava was enhanced by 17% in this study, whereas under water-deficit conditions it was enhanced by a whopping 112%!...
