An area of Arctic sea ice bigger than the United States melted this year, according the UN weather agency, which said the dramatic decline illustrates that climate change is happening "before our eyes."
The massive release of methane and other gases from the Arctic will make it tougher to meet human greenhouse gas cuts, but the scale of the problem will still be determined by how much fossil fuel is burned by humans over coming decades, scientists say.
Warming permafrost can also radically change ecosystems and cause costly infrastructural damage due to increasingly unstable ground.
In the northern hardwood forest, climate change is poised to reduce the viability of the maple syrup industry, spread wildlife diseases and tree pests, and change timber resources.
Earth's atmosphere may be more sensitive to carbon dioxide than previously thought, which means that extreme weather events could become more frequent.
Climate scientists avoid blaming any single weather event like Sandy on global warming. But many say that climate change may well have played an important role in Sandy’s destruction, as well as other recent extreme weather events.
A number of climate factors such as wind, humidity, precipitation and evaporation can affect how glaciers behave.
What do Arctic warming, Hurricane Sandy, and Naval records from the Victorian Age have in common? Everything.
Scientists have shed light on why, unlike the dramatic losses reported in the Arctic, the Antarctic sea ice cover has increased under the effects of climate change.
The new model shows how a melting would alter the topography of "one of the world's refrigerators," potentially affecting adjacent ocean circulation and salinity, and speeding further melting.
Global warming is bad news for winter sports. But that's not the only way climate change will mean culture change, too.
A project to help track Arctic climate change using volunteers to transcribe U.S. ship logs online was launched on Wednesday by the National Archives and the National Oceanic and Atmospheric Administration (NOAA).
National Academy of Sciences recommends crash course for analysts on preparing for rise in sea level and food shortages.
Scientists from NERC's British Antarctic Survey (BAS) and NASA's Jet Propulsion Laboratory (JPL), Pasadena California explain why, unlike the dramatic losses reported in the Arctic, the Antarctic sea ice cover has increased under the effects of climate change.
Global warming could cause frequent and severe failures of the Indian summer monsoon in the next two centuries.
Some scientists say that the key to Sandy's impact may be an extremely rare clash of weather systems.
