Strong evidence suggests that mountain areas are warming more quickly than lower elevations—with serious consequences for water supplies. But historical weather observations from mountain ranges are limited, leaving scientists with plenty of questions.
While many of us were wrapped up in March Madness this spring, Alaska residents and people across the globe participated in a different kind of competition.
In northern Alaska, ponds are shrinking and disappearing as the frozen ground beneath them thaws. The loss may have serious consequences for migratory birds and the subsistence hunters that depend on them.

A map of snow depth across Alaska on March 9 shows the reason for the re-route of the historic sled dog race.
Thanks to back-to-back storms over the last month, most of the Midwest and North-Atlantic regions are covered by snow. But when was the last time there was snow on the ground in all fifty states—even our most tropical destinations, Florida and Hawaii?

Just for fun, we asked the experts at the Rutgers Snow Lab to show us what their data (based on NOAA satellite images) had to say about whether the number of snow-covered days during the week of Christmas has changed at all across the U.S. in the past 50 years.
April snow extent was record low across Europe and Asia, and in June, the entire Northern Hemisphere was below average for the tenth year in a row. Spring snow is disappearing even more rapidly than Arctic sea ice in summer.
