Aaron Putnam’s research in the California Sierras is part of an effort to study glaciers around the world—in Europe’s Alps, the Himalayas, Mongolia, Patagonia, New Zealand. He’s working on an important piece of the worldwide climate puzzle that can help us understand what’s ahead in a warming world.
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.
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.
With the phrase “climate change” disappearing from U.S. federal government websites and increased talk of regulatory overreach, it is obvious that protecting the environment will continue to be a fault line in American political ideology. However, though ideology will shape the nature and speed of response, the environmental problem is real and cannot be ignored.
Researchers studying the West Antarctic Peninsula marine ecosystem will recognize President Obama’s efforts to combat global warming by collecting climate data at an oceanographic station they named for the 44th president.
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.
Rainfall patterns in the Sahara during the six-thousand-year “Green Sahara” period have been revealed by analyzing marine sediments, according to new research.
Many people are concerned that the Republican-controlled Congress and Trump’s administration will stop or reverse the progress the Obama administration has made on climate change. Here’s what you can do about it.
James Hansen, director of the Program on Climate Science, Awareness and Solutions at the Earth Institute and former director of the NASA Goddard Institute for Space Studies, is being honored with the BBVA Foundation Frontiers of Knowledge Award in Climate Change.
Climate change is already affecting New York, and these changes will have profound effects on its ecosystems, plants and animals. What are the implications of these projected changes?
