Impacts of Elevated CO2 on a Freshwater Algae (30 June 2018)
Rising atmospheric CO2 will not only improve the photosynthesis and growth rate of this aquatic species, it will strengthen its defenses against predation, thereby helping to stabilize the aquatic food web...

The Impact of Rising Atmospheric CO2 on Spruce Tree Growth in Southwestern China (29 June 2018)
The modern rise in atmospheric CO2 stimulated the growth of spruce trees by 46.6% and their intrinsic water use efficiency by 30.4% since 1851...

A 4000-Year Record of Climate and War in China (28 June 2018)
A new chironomid-based temperature reconstruction from the northeastern margin of the Chinese Loess Plateau reveals the presence of multiple warm and cold epochs over the past four millennia, the latter of which (cold periods) tended to produce more episodes of social unrest and war...

Can the Quantity of Crop Yields Increase Under Elevated CO2 Without Sacrificing Food Quality? (27 June 2018)
According to the results of this study, it appears that when it comes to rising atmospheric CO2, there is a way that we can have our proverbial cake and eat it too, enjoying both the forecasted increases in crop yields to feed the ever-growing world population without sacrificing plant nutritional quality. And that is great news worth reporting!...
