This has been a sensationally hot summer for America, with records breaking daily. But Greenland seems to have just claimed the heat-related phenomenon crown, with 97 percent of its ice sheet turning to slush. The even stranger part? It might be completely normal--at least for now.
The Northeast U.S. has been taking the brunt of rising sea levels not just in the country but in the world, with waters rising three to four times faster than the global average, according to new data. But that doesn't spare the West Coast; in a decade, rising sea levels could flood the San Francisco International Airport.
When we think of rising sea levels, we think of global climate change and melting ice caps. Yet there's a disparity in the raw data. During the second half of the last century, global sea levels rose 1.8 millimeters per year, according to tide gauges. But it's been determined that melting ice caps and glaciers have only contributed to 1.1 millimeters per year of that. So where did the other 0.7 millimeters come from? A new study has a remarkably simple answer: from you.
Stunning images show the science of global climate change

Gavin Schmidt, NASA climate scientist and one of the nonsense-dispelling bloggers at RealClimate, teamed up with photographer Joshua Wolfe to create the new book Climate Change: Picturing the Science. According to its creators, the book illustrates climate change science through "arresting images and lucid explanations of the science of global warming and the pursuit of global cooperation in adopting new, sustainable ways of living."

A new study released by the University of Colorado at Boulder claims that a global sea rise of more than six feet by the year 2100 is nearly impossible.
The researchers used conservative, medium, and extreme scenarios for Greenland, Antarctica, and the world's smaller glaciers and ice caps. Each scenario produced a result from two feet of sea rise to no more than six feet of sea rise. When factoring in thermal expansion due to warming waters, the team concluded that the most plausible scenario would result in a total sea rise of roughly three feet to six feet by 2100.
