Zack Labe quoted in CBS News story about California rains

From record-shattering snow and relentless rain to astounding extreme events around the globe, it's been a week of unprecedented weather. Climate scientists say these extreme events are becoming more common in our warming world.

The wicked weather along the West Coast has been dominating the U.S. headlines this week. In what has become a repeating pattern this winter, another Atmospheric River has set up shop across California.

Jin-Yi Yu's paper one of most cited papers in Geophysical Research Letters

Subtle but important differences are identified between the 1997/1998 and 2015/2016 extreme El Niños that reflect fundamental differences in their underlying dynamics. The 1997/1998 event is found to evolve following the eastern Pacific El Niño dynamics that relies on basin‐wide thermocline variations, whereas the 2015/2016 event involves additionally the central Pacific (CP) El Niño dynamics that depends on subtropical forcing. The stronger CP dynamics during the 2015/2016 event resulted in its sea surface temperature (SST) anomalies lingering around the International Date Line during the decaying phase, which is in contrast to the retreat of the anomalies toward the South American Coast during the decaying phase of the 1997/1998 event. The different SST evolution excited different wave trains resulting in the western U.S. not receiving the same above‐normal rainfall during the 2015/2016 El Niño as it did during the 1997/1998 El Niño. Ensemble model experiments are conducted to confirm the different climate impacts of the two El Niños.

Benis Egoh joins the ESS Department as an Assistant Professor

This January, Dr. Benis Egoh joined the Earth System Science Department as an Assistant Professor. Her research interests include the mapping and valuing of ecosystem services to understanding the economic consequences of land degradation on human well-being; understanding links between ecosystem services and underpinning biodiversity; and the implementation of current policies related to biodiversity and ecosystem services and options that exist to safeguard or restore priority areas important for both.

Eric Rignot's new research subject of New York Times piece

The Thwaites Glacier on Antarctica’s western coast has long been considered one of the most unstable on the continent. Now, scientists are worried about the discovery of an enormous underwater cavity that will probably speed up the glacier’s decay.

There are plenty of reasons why PG&E is facing bankruptcy, but they all point to one clear solution.

It’s time for Gov. Gavin Newsom to take over this failing investor-owned company and create a thriving public utility in its place.

Eric Rignot interviewed on Science Friday about Antarctic ice melts

Researchers monitoring the condition of the Antarctic ice sheet report that not only is the ice melting, but that the rate of ice loss is increasing rapidly. According to their estimates, around 40 gigatons of ice were lost per year in the 1980s. By the 2010s, that rate of loss had increased to more than 250 gigatons of ice per year. That melting ice has caused sea levels around the world to rise by more than half an inch, the researchers say.

Eric Rignot, climate scientist at the University of California-Irvine and one of the authors of the report, joins Ira to discuss the trends in the ice sheet and what they portend for sea level rise.
