NASA’s Latest Hit: Ice Show from Space
If you don’t know what causes the seasons, you’re not alone: a mini-documentary made in the 1980’s showed that lots of Harvard grads don’t, either. For the record, the reason is that Earth’s spin axis is slightly tilted. In the months surrounding June, the Northern Hemisphere leans toward the Sun. There’s more sunlight, days are longer, and the … Read More
Long-Range Ice Forecast: Things Could Get Very Grim
The best guess now is that a worst-case rise of 2 feet is no longer in the cards. The likely increase in sea level by 2100 now stands at 3 feet, with worst-case scenarios going as high as 6 feet. Three feet would threaten many coastal cities around the world with frequent, powerful floods, as the mildest of storms could send water coursing through … Read More
Image of the Day: ‘Come See Glaciers Before They Melt’
Greenland has been taking center stage in the talks about climate change, with its ice caps and glaciers melting at a rapid pace. And while the conversation is troubling, the attention has proved to be a good thing for Greenland as its tourism is booming… Read More
Image of the Day: Northern Lights in a Dazzling Display
In a photo taken by NASA by the Expedition 30 crew on March 28 from the International Space Station, aurora borealis is seen lighting up the sky next to a sunrise over Ireland and the UK.… Read More
Now You Sea It, Now You Don’t: Watch Arctic Sea Ice Melt
Sea ice extent has declined as the globe has warmed, but the ice cover has thinned as well. Thinner sea ice melts more easily, and as multiyear sea ice is lost, Arctic sea ice has declined more rapidly.… Read More
Going Out on a Limb: Forecasting Snowier Winters?
Global warming-related Arctic sea ice loss may be contributing to snowier winters in parts of the Northern Hemisphere, according to a recent study published in the Proceedings of the National Academy of Sciences. The study takes a look at how Arctic sea ice loss is impacting snowfall in the Midwest, eastern U.S. and parts of Europe and Asia.… Read More
Image of the Day: Greenland Ice Sheet Melting Faster
The Greenland ice sheet is melting quicker than anyone previously thought. A new estimate lowers the amount of heat necessary, and thus the time needed, to melt the Greenland ice sheet, according to Nature Climate Change… Read More
“Chasing Ice” Catches Up to Earth’s Changing Climate
It’s probably hard to imagine all of Manhattan tumbling into the Hudson River and washing away in less than five minutes, but that’s the equivalent of what you’ll see in the film “Chasing Ice,” as a city’s worth of towering icebergs collapse violently into the ocean… Read More
