The Science of Carbon Dioxide and Climate

The vast majority of scientists around the world agree that our climate is changing at a faster rate than ever recorded in human history because of our use of fuels such as coal and oil, so-called fossil fuels. The conclusion rests on basic physics known since the early 1800s, when physical scientists first recognized that carbon dioxide, then a recently discovered gas, could act as a sort of greenhouse, preventing heat introduced by the sun from escaping back into space – the “greenhouse effect.”

Grasslands More Sensitive to Dryness than Rainfall, Study Says

A new study shows that dryness of the atmosphere affects U.S. grassland productivity more than rainfall does. The findings could have important implications for predicting how plants will respond to warming climate conditions.

Shifting Monsoon Altered Early Cultures in China, Study Says

The annual summer monsoon that drops rain onto East Asia has shifted dramatically, at times moving northward by as much as 400 km and doubling rainfall in that northern reach. The monsoon’s changes over the past 10,000 years likely altered the course of early human cultures in China, say the authors of a new study.

Scientists Say They Now Know Why Antarctic Meltwater Stays Below Ocean Surface

Up to now, it has been a mystery why much of the fresh water resulting from the melting of Antarctic ice shelves ends up in the depths instead of floating above saltier, denser ocean waters. Scientists working along one major ice shelf believe they have found the answer.

2016 Sets Another Record for Warmth

The news doesn’t come as a surprise to scientists and others who’ve been watching, but marks a milestone nonetheless: 2016 was the warmest year on record, dating back to the start of modern record keeping in 1880.

Radar Reveals Meltwater’s Year-Round Life Under Greenland Ice

An improved technique developed by a graduate student at Lamont-Doherty Earth Observatory and her colleagues is making it possible to use airborne ice-penetrating radar to reveal meltwater’s life under the ice throughout the year.

Exploring Our Changing Earth, in Real Time

Lamont-Doherty Earth Observatory scientists are loading drones with high-tech instruments and using satellites and undersea cables that are interacting with sensors in some of the most remote locations on Earth to gather data in real time and uncover the secrets of our planet.
