#AGU15 Accidental Geoengineering? Airline traffic may help create an icy haze that’s brightening U.S. skies

SAN FRANCISCO, CALIFORNIA —The data just didn’t seem to make sense. That’s often the story right before scientists make a leap in understanding. In this case, scientists had some evidence that skies in the continental United States have been brightening, after several decades of so-called “dimming.” Brightening and dimming are overly simplified words that signify…

#AGU15 NASA suggests El Niño will lead to "stronger, wetter" atmospheric rivers to ease California's drought

The above images are of Sea Surface Temperature Anomalies (SSTA) of the 1997 (left) and 2015 (right) El Niño. The SSTA are derived from the Advanced Very High Resolution Radiometer (AVHRR) Optimally Interpolated SST that are provided by the Group for High Resolution Sea Surface Temperature (GHRSST) and also use NOAA’s National Center for Environmental…

#AGU15 New NASA satellite maps show humans have less of a fingerprint on global air quality compared to 10 years ago

From the NASA/GODDARD SPACE FLIGHT CENTER Using new, high-resolution global satellite maps of air quality indicators, NASA scientists tracked air pollution trends over the last decade in various regions and 195 cities around the globe. The findings were presented Monday at the American Geophysical Union meeting in San Francisco and published in the Journal of Geophysical…

Reporting from #AGU15

I’m in San Francisco at the American Geophysical Union convention and I will be reporting from here all week. Postings may be a bit erratic, as I have to juggle attendance and time for writing, but I will be live Tweeting regularly from my Twitter feed from the sessions. https://twitter.com/wattsupwiththat The headlines here have already been…
