Here Are 10 Striking Images of Future Sea Levels

You may have heard that the world could be in for 20 feet of sea level rise if the past is any indication according to new research. And if you haven't heard, feel free to get caught up over here. We'll wait. That rise would vastly reshape coastlines around the world and endanger millions of people unless efforts are made to both reduce greenhouse … Read More

Sea Levels Could Rise At Least 20 Feet

Even if world manages to limit global warming to 2°C — the target number for current climate negotiations — sea levels may still rise at least 6 meters (20 feet) above their current heights, radically reshaping the world’s coastline and affecting millions in the process. That finding comes from a new paper published on Thursday in Science that … Read More

Two Maps Show Greenland’s Sudden Melt Season Onset

Two Maps Show Greenland’s Sudden Melt Season Onset

It appears that Greenland’s melt season is making up for lost time. After a cool spring kept Greenland’s massive ice sheet mostly solid, a (comparatively) warm late June and early July have turned half the ice sheet’s surface into liquid, well outside the range of normal for this time of year. Despite the ice sheet’s remote location, its slushy… Read More

Twitter Could Shape Flood Disaster Response

Twitter Could Shape Flood Disaster Response

First the rains came. Then the floods. Then the tweets. In late January 2014, Jakarta was inundated with heavy rain. So much rain fell that the region saw 16 inches more rainfall than normal for the month. Rivers rose and punctured their banks, spilling onto the streets of the Indonesian capital. Flood waters reached over 6 feet in some areas and … Read More

Here’s Why the Global Warming Hiatus Might Not Exist

Here’s Why the Global Warming Hiatus Might Not Exist

The global warming hiatus — a decade-plus slowdown in warming — could be chalked up to some buoys, a few extra years of data and a couple buckets of seawater. That’s the finding of a new study published on Thursday in Science, which uses updated information about how temperature is recorded, particularly at sea, to take a second look at the global … Read More

Climate Change Poses a Brewing Problem for Tea

Climate Change Poses a Brewing Problem for Tea

A myth ties the origins of tea to an errant gust of wind that blew tea leaves into a Chinese emperor’s hot water more than 4,700 years ago. Since that lucky first brewing, tea has become the second most popular beverage in the world (behind water, of course). The industry has grown into a $20 billion behemoth that sells everything from pedestrian … Read More
