Plant Growth Database (14 August 2018)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Wheat (Asif et al., 2017). To access the entire database, click here.

The Relationship Between Diurnal Temperature Range and Mortality in Hefei, China (13 August 2018)
As the diurnal temperature range (DTR) falls, so too does the relative risk of non-accidental, cardiovascular and respiratory mortality. And since the DTR has been falling in recent decades, it would appear that global climate change is saving lives!...

Another Example of Corals Being Capable of Biologically-Mediating their Calcification to Overcome Ocean Acidification (10 August 2018)
As concluded by the authors of this new paper, "although the role of calcium concentrations within the coral calcifying fluid in driving calcification has often been neglected, increasing [it] may be a key mechanism enabling more resistant corals to cope with ocean acidification and continue to build calcium carbonate skeletons in a high-CO2 world." And that great news suggests that horror stories of corals being driven to extinction because of ocean acidification are far from certain -- if they contain any truth at all!...

A Global Warming Hiatus in Northeast China (9 August 2018)
Over the past two decades temperatures in this region have not only failed to warm as the climate models project they should, they have cooled. And that cooling, if it continues, poses a significant threat to agricultural production in this region...

Plant Growth Database (7 August 2018)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Soybean (Li et al., 2017). To access the entire database, click here.

Elevated Temperature Mitigates the Negative Impacts of Ocean Acidification on Porites Calcification (6 August 2018)
According to the authors of this study, at high seawater pCO2, a 3°C increase in temperature substantially mitigates the effects of ocean acidification on calcification: "at 25°C the mean Porites spp. calcification rate at seawater pCO2 750 µatm is ~40% of the rate observed at 180 µatm. In contrast, at 28°C this figure is ~100%"...

The Combined Impacts of Elevated CO2, Salinity and Vapor Pressure Deficit on Cucumber (5 August 2018)
Elevated CO2 increased plant photosynthesis and growth, fully ameliorating the negative impacts of vapor pressure deficit and salinity on these two parameters. Thus, in the future, if the air gets a little dryer or the soils a little saltier, as long as the air's CO2 content continues to rise, cucumber growth should be maintained or increase relative to that of today...

The Resilience of a Caribbean Inshore Patch Reef to Temperature Stress (3 August 2018)
Despite experiencing a more severe thermal stress event in 2015, the degree and severity of coral bleaching among 4234 colonies on this Caribbean reef was much less than that observed following a bleaching event in 2014...

A 230-Year Record of Drought in Kazakhstan (2 August 2018)
One characteristic of this reconstruction is rather obvious: there is nothing unusual, unnatural or unprecedented about the drought record of the past few decades, except perhaps that it appears to be less variable and less severe. Thus, if there has been a CO2-induced influence on the drought record, it surely has been a favorable one...

The Effects of CO2 and Temperature on Rice Yields (1 August 2018)
Who would imagine that a small, 60 ppm, increase in atmospheric CO2 would be sufficient to significantly boost rice yields and ameliorate growth-reducing effects of elevated temperature?...

Plant Growth Database (31 July 2018)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Stevia (Hussin et al., 2017). To access the entire database, click here.

Elevated CO2 Overpowers the Effects of Drought in Wheat (30 July 2018)
Rising concentrations of atmospheric carbon dioxide will increase the yield of wheat, even during times of moderate to severe drought (relative to well-watered and ambient CO2 conditions of today). And on those rare instances of extreme drought, wheat yields of tomorrow should still be similar to those observed under well-watered conditions of today, thanks to the incredible molecule -- CO2 -- that we like to call the elixir of life!...

The Outer Reefs of Moorea Island: Back From the Dead! (27 July 2018)
Despite suffering two major disturbance outbreaks over the past three decades, coral cover on the outer reef slope has remarkably recovered to pre-disturbance levels...

The Combined Effects of Elevated CO2 and Water Deficit on Cacao (26 July 2018)
According to the authors of this study, the "positive effect of CO2 may ameliorate growth reductions caused by water limitation in the future," which "could potentially improve pod yields [of cacao] by supporting a larger number of pods per tree." And that is sweet news for the farmers who grow -- and the consumers who utilize -- cacao for its confectionary delights!...

Elevated CO2 Alleviates the Negative Effects of Drought Stress in Cucumbers (25 July 2018)
By improving photosynthetic performance and inducing changes in leaf tissue structure, elevated CO2 reduces the negative effects of drought in this important crop...
