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.”
Anne Hidalgo, the mayor of Paris, will join dozens of other leaders in government, business and the non-profit world at the Women4Climate conference at Columbia University on March 15.
While President Trump has promised to pull the U.S. out of the Paris climate accord, China’s President Xi Jinxing has vowed to continue to tackle climate change and honor his country’s obligations. Will China become the global leader in combating climate change?
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.
