Wetter Climate Likely to Intensify Global Warming Due to Increased CO2 Release by Microbes
Greater tropical rainfall may increase microbes’ release of CO2 from soils into air. A study in the May 6, 2020, issue of Nature indicates the…
For 7 Years Proba-V Monitored the Daily Growth of All Earth’s Vegetation – Now It Has a New Mission
ESA’s cubic-meter-sized Proba-V minisatellite will soon end its nearly seven-year global mission to monitor the daily growth of all Earth’s vegetation. As Copernicus Sentinel-3 takes…
Cold Air Rises – How Wrong Are Our Global Climate Models?
The lightness of water vapor buffers climate warming in the tropics. Conventional knowledge has it that warm air rises while cold air sinks. But a…
