Resilience of Central Pacific Corals to Repeated Heat Stress Events (24 June 2019)
Despite similar episodes of temperature stress caused by El Niño events only five years apart, coral bleaching severity was lower in the latter episode, suggesting the corals experience some degree of physiological acclimation to temperature-induced stress...

Elevated CO2 Improves Soybean Growth and Mitigates the Impact of Water Deficit (21 June 2019)
Not only did elevated CO2 increase soybean photosynthesis and growth in this experiment, but it helped improve plant water use efficiency so as to maintain photosynthetic rates under conditions of short-term water deficit...

Analyzing the Effects of Temperature on Human Mortality in China (12 June 2019)
Two key findings are illuminated in this study: (1) cold weather is much more deadly than warm weather, (2) temperature-related mortality rates are higher in regions with lower GDP. A welcomed solution to this health crisis, where the annual deaths due to cold weather events exceed mortality due to leukemia and brain tumors, would be for China to continue its onward trend toward modernization by continuing its policy of utilizing its vast fossil fuel resources to produce abundant and cheap energy...
