An alarming new report reveals the last five years have been the region's hottest in recorded history.
Scientists grapple with whether a vast submarine wall in front of an unstable glacier could prevent dangerous sea level rise or everyone should just move away from coastal areas.
Sea ice has hit record lows for this time of year, data also show. "It's just crazy, crazy stuff," says a scientist who has been studying the polar region since 1982.
From the Himalayas to Switzerland, glaciers are melting, threatening vital water supplies and increasing the risk of sea-level rise.
Climate change has shrunk Bolivian glaciers and left cities without water.
Summer water shortages caused by the reduction of glacier ice mass could be alleviated by dams constructed to contain springtime runoff from melting snow.
Back in 1962, the fossil fuels giant was bragging about its ability to heat up the Arctic.
The speed at which the warming climate is melting glaciers in Central Asia may ruin the water supply of millions of people within 50 years.
Scientists say tens of thousands of glaciers are melting faster than ever -- and many will continue to do so even if climate change can be stabilized.
Global temperatures have risen by 1 degree Celsius (nearly 34 degrees Fahrenheit) in the past 150 years, and one scientist says a doubling of that could unleash catastrophic sea-level rise this century.
