The Interaction of CO2 and Temperature on Yields in a Double Rice Rotation
(1 April 2020)
The future looks incredibly bright for rice yields as data from a four-year field study show yield enhancements of up to 29% in response to a 2°C rise in temperature and a meager 60 ppm increase in atmospheric CO2...

A 167-year Precipitation Record from the Lower Yangtze River Basin
(30 March 2020)
Based on the data presented in this study, it would thus appear that late 20th century and early 21st century warming had a mitigating impact on the frequency of anomalous precipitation events in the lower Yangtze River basin, which conclusion is opposite that typically expected by climate alarmists...

Historic iWUE Trends in Far Northeastern China
(25 March 2020)
Since 1900, the intrinsic water use efficiencies of larch and pine trees have risen by 22.7% and 31.8%, thanks to the supposed twin evils of the radical environmental movement: rising temperatures and rising atmospheric CO2. How ironic is that?...
