While U.S. action on climate change remains stalled, four south Florida counties have joined forces to plan for how to deal with the impacts — some of which are already being felt — of rising seas, higher temperatures, and more torrential rains.
Some skeptics have suggested the real culprit behind rising temperatures is increased solar activity. But a wide variety of data and experiments still provide no solid evidence to refute the scientific consensus that greenhouse gas emissions are the major reason the planet is heating up.
Forecasting what the Earth’s climate might look like a century from now has long presented a huge challenge to climate scientists. But better understanding of the climate system, improved observations of the current climate, and rapidly improving computing power are slowly leading to more reliable methods.
As climate scientists wrestle with the complexities of how the planet will react to rising greenhouse-gas levels, no variable is more difficult to decipher than the impact of clouds. But thanks to new satellite data and other technologies, clues are emerging that may help solve the puzzle.
The surest sign of a warming Earth is the steady melting of its ice zones, from disappearing sea ice in the Arctic to shrinking glaciers worldwide. Now, scientists are using increasingly sophisticated satellite technology to measure the extent, thickness, and height of ice, assembling an essential picture of a planet in transition.
As the world warms, sea levels could easily rise three to six feet this century. But increases will vary widely by region, with prevailing winds, powerful ocean currents, and even the gravitational pull of the polar ice sheets determining whether some coastal areas will be inundated while others stay dry.
For more than 40 years, scientists have dreamed of collecting the sun’s energy in space and beaming it back to Earth. Now, a host of technological advances, coupled with interest from the U.S. military, may be bringing that vision close to reality.
A new U.S. government report paints a disturbing picture of the current and future effects of climate change and offers a glimpse of what the nation’s climate will be like by century’s end.
Princeton physicist Freeman Dyson has been roundly criticized for insisting global warming is not an urgent problem, with many climate scientists dismissing him as woefully ill-informed. In an interview with Yale Environment 360, Dyson explains his iconoclastic views and why he believes they have stirred such controversy.
Issued less than two years ago, the report from the Intergovernmental Panel on Climate Change was a voluminous and impressive document. Yet key portions of the report are already out of date, as evidence shows the impacts of warming intensifying from the Arctic to Antarctica.
