CU Boulder ice experts report: Arctic sea ice at lowest maximum for second consecutive year

Arctic sea ice was at a record low maximum extent for the second straight year, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder and NASA. "I've never see such a warm, crazy winter in the Arctic,” said NSIDC director Mark Serreze. “The heat was relentless." Air temperatures over the Arctic Ocean for the months of December, January, and February were 2 to 6 degrees Celsius (4 to 11 degrees Fahrenheit) above average in nearly every region. Sea ice extent over the Arctic Ocean averaged 14.52 million square kilometers (5.607 million … [Read more...]

“Hot Spot” Near Four Corners Produces Largest Methane Concentration in the U.S.

Scientists at NASA and the University of Michigan have published a new study showing that an area at the intersection of Colorado, New Mexico, Arizona and Nevada is a "hot spot" for methane emissions. In each of the seven years studied from 2003 to 2009, the area released about 0.59 million metric tons of methane into the atmosphere. This is almost 3.5 times the estimate for the same area in the European Union's widely used Emissions Database for Global Atmospheric Research. The gas measured in the study comes from leaks in processing equipment, and is not attributed to fracking, … [Read more...]
