Elevated CO2 Improves Rice Yields Under Both Well-watered and Water-stressed Conditions (19 January 2018)
In the future, rising atmospheric CO2 concentrations will increase rice yields under normal watering conditions (needing less water to do so), while under water-deficit conditions it will help to mitigate (and potentially overcome) yield losses...

Ocean Acidification Fails to Impact the Behavior and Body Size of a Common Copepod (18 January 2018)
Another study reveals an absence of negative impacts under either acute or long-term exposure to reduced seawater pH...

Two Decades of Forest Productivity Enhancement (17 January 2018)
A study of 23 temperate and boreal ecosystems reveals a respectable 19 percent increase in gross primary production and an impressive 31 percent increase in net ecosystem production, courtesy of the beneficial impacts of atmospheric CO2 fertilization...

Plant Growth Database (16 January 2018)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Tobacco (Ruiz-Vera et al., 2017). To access the entire database, click here.

Six Decades of Glacial Advance in the Western Ross Sea, Antarctica (15 January 2018)
Over the past 60 years glaciers along the western Ross Sea in Antarctica have not been behaving like the canary in the coal mine they are supposed to represent...

The Interaction Between Salinity and Short-term CO2 Enrichment of a Perennial Herb (12 January 2018)
Short-term CO2 enrichment helps a perennial herb with multiple therapeutic benefits withstand the detrimental effects of a saline growing environment...

Elevated CO2 Improves Photosynthesis and Growth in an Endemic Antarctic Macroalga Species (11 January 2018)
Under every possible combination of temperature and irradiance treatment levels examined by the authors of this study, elevated CO2 concentrations at 1000 ppm stimulated net photosynthesis and growth of this macroalga species by 30-50 percent compared to what was observed under ambient CO2 conditions (380 ppm)...

The Impact of the Diurnal Temperature Range on Human Mortality in China (10 January 2018)
An increase in the diurnal temperature range (DTR) increases non-accidental and cardiovascular mortality, while a decrease in DTR saves lives. Fortunately, over the past few decades the DTR has been declining in China as temperatures have warmed, which warming has resulted in a saving of lives!...

Plant Growth Database (9 January 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 (Sanz-Sáez et al., 2017). To access the entire database, click here.

CO2-enhanced Heat Tolerance of a C4 Perennial Grass Species (9 January 2018)
Following four weeks of heat stress, elevated CO2 suppressed heat-induced damages and improved the heat tolerance of bermudagrass...

Barley Yield and Belowground Rhizosphere Response to Atmospheric CO2 Enrichment (8 January 2018)
It looks to be a win-win situation. Elevated CO2 increases barley yield and stimulates the belowground input of plant-derived nutrient compounds that benefit the rhizosphere prokaryotic community, which feeds upon them...

Plant Growth Database (4 January 2018)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Chinese Yam (Thinh et al., 2017). To access the entire database, click here.

The Combined Impact of Hypoxia and Ocean Acidification on Four Estuarine Fishes (3 January 2018)
The authors report finding no evidence of a CO2 effect on the survival or stress of the fish despite experimental pH concentrations reaching levels as low as 6.8, which correspond to CO2 levels of 12,000 ppm...

Elevated CO2 Promotes a Rhizosphere-driven Increase in Nitrogen and Phosphorus Availability (2 January 2018)
New research suggests that plants can shape the composition of their rhizosphere microbiomes, enhancing soil organic matter decomposition and nutrient availability under elevated concentrations of atmospheric CO2, which is great news for nutrient-poor ecosystems...

Plant Growth Database (1 January 2018)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Rice (Nakano et al., 2017). To access the entire database, click here.
