The word “crevasse” sends shivers down the spine of anyone who works on a glacier. Sometimes hundreds of feet deep and hidden beneath a thin layer of snow, these cracks have claimed the lives of many polar explorers and scientists. They also appear quite frequently in our sensors as we fly our survey flights for Rosetta-Ice.
This phenomenon can cause major changes in climate patterns. See what’s in store for your region.
Concurrent with the announcement that human carbon emissions reached a new peak this year, Galen McKinley, a researcher at Columbia University’s Lamont-Doherty Earth Observatory, discusses the difficulties of tracking the sources and destinations of carbon dioxide.
For scientists mapping Antarctica’s Ross Ice Shelf, data collection flights require a demanding schedule: The day starts at 4am and sometimes continues throughout the night.
Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. But it not directly measurable from space, due to the abundance of ozone higher in the atmosphere, which masks the surface. Now, researchers have devised a way to use satellite measurements of the precursor gases that contribute to ozone formation to predict when and where ozone will form.
Every four years Congress is provided with a state-of-the-art report on the impacts of climate change on the United States. The next National Climate Assessment is scheduled for 2018, but its scientific findings are scheduled to be published today. Here, two of its authors explain what to expect.
Even though our tent is within a short drive of McMurdo (a small town with most of the safety and logistical equipment on the entire continent), we still need to prepare ourselves for sudden, extreme weather. Every time we leave the relative safety of McMurdo, we carry our Extreme Cold Weather equipment and our tent has emergency food and sleeping equipment.
A new study says that storms of intensities seen today, combined with a few meters increase in sea level, were enough to transport coastal boulders weighing hundreds of tons more than 100,000 year ago.
During a show at the Hayden Planetarium, seismologist Ben Holtzman explains how he turns earthquake data into captivating sounds and visualizations.
