Elevated CO2 Improves the Nitrogen Resorption Efficiency of Red Maple (20 September 2019)
A doubling of CO2 increased nitrogen resorption efficiency (NRE) by approximately 50%. Thus, by remobilizing nitrogen from senescent leaves and transporting it to other plant parts, elevated CO2 is helping NRE to become an increasingly important N source for the early growth of red maple the following year...

The Effect of CO2 and Temperature on Soybean Seed Nutrition (13 September 2019)
From a nutritional perspective, as concluded by the authors of this study, "the potential threat to human nutrition by increasing CO2 concentration may not be realized." Cue the cursing and gnashing of teeth by climate alarmists!...
Negligible Effects of Ocean Acidification on a Juvenile Coral Reef Fish (12 September 2019)
