Exercise is one of the top benefits for cyclists, but the health effects of air pollution on riders is less well-known. Scientists including Lamont-Doherty's Steven Chillrud are trying to figure out what those health effects might be to help create a safer commute.
In a video, Lamont-Doherty geophysicist Chris Small discusses his work that led to a 2015 Golden Goose Award, presented at the Library of Congress.
Lamont's Steve Chillrud and Columbia Public Health's Darby Jack are outfitting New York City cyclists with air-monitoring equipment to determine how the intensity of their workouts affects the amount of pollution they inhale and the impact pollution has on their cardiovascular systems.
“The prospect that somebody else was turning rocks into cutting instruments half a million years before our earliest known ancestors were walking around northern Africa rewrites the book on everything we thought we knew about early tool usage,” said Lamont geologist Christopher Lepre.
Lamont's Taro Takahashi used Exxon's tanker records to conclude that the oceans absorb only about 20 percent of the CO2 from the burning of fossil fuels and other human activities. The paper earned Takahashi a "Champions of the Earth" prize from the United Nations.
Congressman Mark Pocan of Wisconsin honored Lamont-Doherty's Chris Small from the floor of the U.S. House for his work that won a 2015 Golden Goose Award.
Newly updated ship and satellite data analyzed by Lamont's Taro Takahashi show that CO2 uptake started growing again in 2002, and that the Southern Ocean is now absorbing proportionately as much CO2 as ever.
Sen. Ed Markey of Massachusetts joined colleagues in praising the winners of the 2015 Golden Goose Award, including Lamont-Doherty geophysicist Chris Small.
California is in the fourth year of a severe drought with temperatures so high and precipitation so low that rain and snow evaporate almost as soon as they hit the ground. Cites research by Lamont's Park Williams.
“This really highlights the need for more tree ring data for the Sierra Nevada," says Lamont's Park Williams.
Lamont-Doherty geochemist Steven Chillrud describes his study underway that is fitting cyclists across New York with sensors to map out air quality around the city.
Lamont geophysicist Chris Small has won a 2015 Golden Goose Award for his work on how human populations are distributed with respect to altitude. The award was created by a coalition of business, university, and scientific organizations.
Lamont Scientist Chris Small's curiosity about altitudes where people live has led to advances in cancer research, semiconductor manufacturing, food marketing, and more.
Two decades ago two curious scientists from very different fields wondered how many people live at various altitudes. Aided by federal funding, their inquiries have helped in area ranging from disaster preparedness to cancer research. Focuses on research by Lamont's Chris Small.
WNYC talks with a member of the Bicycle Brigade, a group of cyclists helping Lamont's Steven Chillrud and Columbia Public Health's Darby Jack track the effects of pollution on riders throughout New York City.
A new project involving Lamont's Nicolas Young will study how rising temperatures and altered Arctic precipitation patterns could affect the Greenland Ice Sheet.
Urban bicycling has many benefits, but it comes with risks, including inhaling air pollutants. Lamont-Doherty's Steven Chillrud and Columbia Health's Darby Jack set out to measure what riders are exposed to, how much actually gets into their bodies, and whether it affects riders’ health.
A study from Lamont-Doherty's Richard Seager found that global warming doubled to tripled the risk of a crippling drought in the Fertile Crescent as severe as the one that occurred shortly before the fighting broke out.
Global warming does not cause the conflicts that have caused mass movement of people, but it would be wrong to say it does not contribute. Cites research by Lamont-Doherty's Richard Seager.
Lamont geophysicists Maya Tolstoy and Delwayne Bohnenstiehl used recordings from three underwater microphones to determine the speed at which the earth tore: almost 3 kilometers per second.
