A meteor or comet impact near Quebec heaved a rain of hot melted rock along the Atlantic Coast about 12,900 years ago, a new study claims. The new research impacts a controversial theory about a big climate shift called the Younger Dryas.

Cooling sea-surface temperatures over the tropical Pacific Ocean — part of a natural warm and cold cycle — may explain why global average temperatures have stabilized in recent years, even as greenhouse gas emissions have been warming the planet.

When rain falls on Australia's vast inland plains, the continent soaks up water like a sponge instead of sending surface runoff back out to sea via streams and rivers. For an 18-month period starting in early 2010, so much rain fell over Australia that gl

The Arctic is losing about 30,000 square miles (78,000 square kilometers) — an area roughly equivalent to the state of Maine — of sea ice each year, NASA scientists say.

This animation shows changes in Arctic sea ice cover between May 2013 and August 2013. The sea ice cap, which has significantly thinned over the past decade, can be seen retreating quickly during the first half of July.

The results run contrary to previous studies that found increases in Antarctic penguin populations during warmer climates and decreases during colder climates, providing insight into how penguins may respond to climate change.

Humans are most likely to blame for warming temperatures across the globe in recent decades, according to an international committee of scientists. These findings are part of an impending report from the Intergovernmental Panel on Climate Change.

Coastal areas around the globe could see $1 trillion in damage a year by 2050 if no mitigating steps are taken, but planning ahead could dramatically reduce the damage, new research suggests.

Cities in North America and Asia are most vulnerable to coastal flooding, new research suggests.

Manmade global warming could lead to the melting of Earth's ice caps, which could cause rapid sea level rise. The shift in water onto the margins of the continents could cause underwater landslides that themselves can trigger tsunamis.

Is climate changing too quickly for ecosystems to keep pace?

What happens under Greenland's ice sheet, where water, ice and rock meet, is key to predicting how its glaciers will react to global warming. Beneath the island's mysterious middle, where the ice is thick and the bottom bedrock hard to reach, meltwater fl

The modern meltdown of the Antarctic Ice Sheet mirrors the frozen continent's big thaw after the last ice age ended 20,000 years ago, a new study finds. New ice core records from West Antarctica show the huge ice sheet started heating up about 20,000 to 2

Superstorm Sandy was not only a vivid demonstration of the effects of climate change, but of the sociological issue of how society views risk. The public focus has shifted to national security at the expense of preparation for extreme weather events.

The hole in the planet's ozone layer may be shifting wind patterns and cloud cover over Antarctica in a way that could be triggering slightly warmer global temperatures, a new study finds.

2012 was a year of climate records, from temperatures to ice melt to sea level rise, a newly released report on the state of the global climate says. Even though natural climate cycles have slowed the planet's rising temperature, 2012 was one of the 10 ho

A new study points to an armada of icebergs or meltwater from Greenland as a possible cause for the sudden climate change called the Younger Dryas, or the Big Freeze. Starting roughly 12,900 years ago, the Big Freeze halted the Northern Hemisphere's trans

A polar bear named Tasul at the Oregon Zoo has been wearing a collar cam that shows what the world looks like through the Arctic animal’s eyes. Researchers will use data collected from Tasul's everyday movements to study the species' wild behavior.
