Ocean Acidification Impacts on a Marine Diatom (28 February 2019)
Multiple growth-related parameters remained unchanged in Skeletonema pseudocostatum in response to reduced seawater pH. In addition, there appeared to be no impact on the nutritional quality of this diatom as a primary producer in the marine food web...

Attributable Fraction of Temperature-Related Cardiorespiratory Deaths in the USA (27 February 2019)
For the USA as a whole, human mortality due to cold weather is more than sixteen times larger than that due to warm weather. And so it is that perhaps we should all pray for a little more global warming...

Plant Growth Database (26 February 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 (Uddin et al., 2018). To access the entire database, click here.

The Net Photosynthetic Response of Nine Taro Genotypes to Elevated CO2 (25 February 2019)
Photosynthetic increases of 61 to 113 percent were observed in all genotypes at 1000 ppm CO2 compared to ambient concentrations (400 ppm)...

Elevated CO2 is Enhancing Global Terrestrial Net Ecosystem Production (22 February 2019)
Over the period 1995 to 2014, global net ecosystem production increased by 117 to 178 Tg C per year depending on calculations utilized. And the vast majority of that increase (~90%) was due to the aerial fertilization effect of rising atmospheric CO2...

Elevated CO2 Mitigates the Stress of Waterlogging in Sweet Cherry (21 February 2019)
Higher levels of atmospheric CO2 ameliorate growing-related stresses of waterlogging, which is yet another benefit in the long list of benefits of atmospheric CO2 enrichment on plants...

A 119-Year Temperature Reconstruction for the South China Sea (20 February 2019)
It appears that the proxy temperature record of the South China Sea does not support the narrative that rising atmospheric CO2 is causing dangerous climate change...

Plant Growth Database (19 February 2019)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Cucumber (Liu et al., 2018). To access the entire database, click here.

The Impact of Ocean Acidification on Phytoplankton Fatty Acid Production (18 February 2019)
Observed increases in polyunsaturated and monounsaturated fatty acids under ocean acidification in the three phytoplankton species examined reveal increased nutritional value for zooplankton and other higher-level animals in the marine food web...

Atoll Island Stability in the Face of Climate Change (15 February 2019)
Despite model-based claims to the contrary, small island States are in no danger of drowning from rapidly rising seas caused by CO2-induced global warming...

The Impact of Elevated CO2 on a Red Macroaglae Under Low Light Conditions (14 February 2019)
Results of this study reveal that "ocean acidification can alleviate the negative effect of low light conditions on the growth of P. yezoensis, suggesting that the primary productivity of this algae will benefit from the increase in CO2 in the future"...

The Interaction Between Elevated CO2 and Drought on Sweet Potato (13 February 2019)
It should come as no surprise to regular readers of CO2 Science that elevated CO2 ameliorates the adverse effects of drought stress on this key food crop...

Plant Growth Database (12 February 2019)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Cacao Tree (Lahive et al., 2018). To access the entire database, click here.

Future Forest Response to Rising Atmospheric CO2 and Climate Change in Northwest China (11 February 2019)
Forest managers should be excited about the 37% increase in forest net primary productivity predicted for this region of northwest China by 2050, courtesy of rising atmospheric CO2 concentrations and forecasted accompanying changes in climate...

Transgenerational Acclimation to Warming of a Reef Fish (8 February 2019)
It is becoming ever so clear that predictions of widespread animal extinctions due to global warming are unlikely to occur. Millions of years of evolution have given them the inherent ability to adapt to almost any environmental change they could realistically face...

A CO2-Induced Enhancement of Peatland Carbon Sequestration (7 February 2019)
A 400 ppm enhancement of atmospheric CO2 boosted the biomass production of three Sphagnum species by 43, 101 and 130 percent, while simultaneously increasing their CO2 sink strength by a factor of three...

Improved Water Use of Four Desert Species Under Elevated CO2 (6 February 2019)
Atmospheric CO2 enrichment up to 1600 ppm improved plant water use efficiencies by up to a whopping 412 percent!...

Plant Growth Database (5 February 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.

The Impact of Diurnal Temperature Range on Stroke Mortality in China (4 February 2019)
The percent increase in stroke mortality from a one degree rise in diurnal temperature range on cold days is more than five times greater than that observed on hot days...

Response of a Mediterranean Red Algae to Ocean Acidification (1 February 2019)
Relative growth rates of this calcifying macroalgae increased by nearly 50% in the low seawater pH treatment, suggesting that ocean acidification will not negatively impact this particular species...
