Five Ozone-Depleting CFCs Increased Globally From 2010-2020

A new paper in Nature Geoscience written by an international team of scientists led by Dr. Luke Western of the National Oceanic and Atmospheric Administration (NOAA) shows that atmospheric abundances and emissions of five chlorofluorocarbons (CFCs) increased between 2010 and 2020, despite the 2010 Montreal Protocol that banned CFC production for dispersive use.

Warming Makes Droughts, Extreme Wet Events More Frequent, Intense

Scientists have predicted that droughts and floods will become more frequent and severe as our planet warms and climate changes, but detecting this on regional and continental scales has proven difficult. Now a new UMD and NASA study confirms that major droughts and pluvials – periods of excessive precipitation and water storage on land – have indeed been occurring more often.

Virtual Workshop on “Precipitation Estimation from LEO Satellites: Retrieval and Applications”

Last week, NOAA NESDIS held a two-day virtual workshop on “Precipitation Estimation from LEO Satellites: Retrieval and Applications”. The workshop was organized by CISESS Consortium Scientist Kuolin Hsu at University of California, Irvine through a task funded by NESDIS’ Joint Polar Satellite System (JPSS) Program Office. The primary goal of the workshop was to determine future satellite observation requirements for global precipitation. The workshop had nearly 100 participants for each of the four sessions that spanned two days.
