In a remote desert region around Kenya’s Lake Turkana, paleoecologist and geochemist Kevin Uno collects fossils and sediments, searching for evidence about past climate, vegetation, animals, and water. His goal: to understand how climate affected our ancestors millions of years ago.
Some towns and cities can get soaked even when the skies are dry—and these so-called sunny day floods are on the rise thanks to climate change.
Students from the MPA in Environmental Science and Policy program at SIPA have produced a podcast called “Greener on the Other Side,” on sustainability, climate change, and the environment.
The Rosetta team made two big accomplishments this week: Our lidar returned some beautiful 3D images of the sea ice topography, which can be used to study small details of the ice. And our own Chloe Gustafson won first place in the Antarctic Turkey Trot. She now holds the honor of being the first woman to win the race!
Seismologist Lynn Sykes has been working for more than 50 years to halt the testing of nuclear bombs. In his forthcoming book, Silencing the Bomb: One Scientist’s Quest to Halt Nuclear Testing, Sykes provides an insider’s look at the science behind detecting explosions, and international efforts to establish a series of treaties.
They’re rare but can be dangerous, as demonstrated by Medicane Numa’s destruction in Greece last week.
The theme of the past week has been the weather. Weather is of course always happening, but in the lingo of McMurdo Station, ‘weather’ means ‘bad weather.’
Tightly packed sediments help the Cascadia Subduction Zone generate large earthquakes, and could boost its ability to trigger a large tsunami.
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.
Two solar arrays in Upstate New York will be up and ready at the end of November, poised to provide power and to help to reduce the Lamont campus’ carbon footprint.
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.
