New ESS Publication: Undercutting of marine-terminating glaciers in West Greenland

Marine-terminating glaciers control most of Greenland's ice discharge into the ocean, but little is known about the geometry of their frontal regions. Here we use side-looking, multibeam echo sounding observations to reveal that their frontal ice cliffs are grounded deeper below sea level than previously measured and their ice faces are neither vertical nor smooth but often undercut by the ocean and rough. Deep glacier grounding enables contact with subsurface, warm, salty Atlantic waters (AW) which melts ice at rates of meters per day.

GLACIER Conference to Address Climate Change Impacts in the Arctic

"GLACIER will focus the world’s attention on the most urgent issues facing the Arctic today and provide an unprecedented opportunity for foreign ministers and key stakeholders to define the region’s most crucial challenges; highlight innovative ways in which these challenges can be addressed at the local, national and international levels; and broaden global awareness of the impacts of Arctic climate change."

2015 Amazon Fire Forecast

"Scientists at NASA and the University of California, Irvine, project fire risk for South America's Amazon Basin in 2015 to fall along an east-west divide. According to their model, based on multiple satellite datasets, the forests of the western Amazon will experience average or below-average fire risk, while those in the eastern Amazon will see above-average risk."

UCI News: Economic slump, not natural gas boom, responsible for drop in CO2 emissions

Steve Davis

Irvine, Calif., July 21, 2015 – The 11 percent decrease in climate change-causing carbon dioxide emissions in the U.S. between 2007 and 2013 was caused by the global financial recession – not the reduced use of coal, research from the University of California Irvine, the University of Maryland, and the International Institute for Applied Systems Analysis shows.
