Mark Flanner at the University of Michigan and his collaborators used satellite data to measure how much changes in snow and ice in the Northern Hemisphere have contributed to rising temperatures in the last 30 years. The loss of snow and ice warmed the planet more than models predicted it would. Snow and ice help [...]

Pakistani rains of 2010 washed away high snowfields of the Hindu Kush
These Modis Modis Terra satellite “before and afters” drop down in 3 steps toward Pakistan and the Indus Valley. That is the Hindu Kush. They are from July 26, 2010 , and August 16, 2010. The average altitude of these mountains is 14,700 feet. When it was raining in the valleys it also was raining [...]
Snow cover season decreasing 5 days/decade
Spatial and temporal patterns in the onset, offset, and length of the snow season across Northern Hemisphere continents are examined for the period from 1967 to 2008. Full snow seasons (FSS) and core snow seasons (CSS) are defined based on the consistency of snow cover within a location over the course of the cold season. [...]
