More carbon dioxide in the atmosphere also makes the oceans more acidic — and that's bad news for many marine creatures that rely on calcium carbonate shells to survive. But it's not that simple, scientists are discovering: Not all shell-building creatures respond the same way to acidifying seawater.

As the climate changes, warmer conditions are creeping northward — and termites, among other creatures, are likely to expand their territories into higher latitudes. Those areas, however, are currently ill-equipped to handle termites, which could cause billions of dollars in property damages.

Washington, D.C., has been buried in snow over the last week, prompting many people to ask what that means about global warming. The answer? Nothing: It’s weather, not climate.

Climatologist Michael Mann met the press today at the American Geophysical Union's fall meeting to answer questions about "Climategate" and what those hacked emails really said about climate science.

Is the developed world outsourcing its carbon dioxide emissions? And if so — should we help pay for them?

Sequestering carbon dioxide in underground aquifers may be one way to remove it from the atmosphere. But, once stored underground, will the greenhouse gas stay put? Evidence suggests that the gas mainly dissolves in the water, not the rock — but that should still keep it secure.

Scientists are exploring a range of ways to capture carbon dioxide emitted by smokestacks and sequester it underground. One new solution may lie in a circular, bowl-shaped compound that draws carbon dioxide right out of the air.

The first climate report from Barack Obama's presidency synthesizes existing scientific data and has a strong message: Climate change isn't coming; it's already here. The next question: What the country should do about it.gdmfu52rxt

Many glaciers in the American West are shrinking — but some are advancing, while others have retreated little since the 1970s. So what controls their fate? Temperature, topography, precipitation and location all play a role in how glaciers respond to climate change.

Climate change policy isn't just about science — it has to consider economics, legal and social issues. By glossing over those, researchers say, scientists are having trouble getting their message across.

A new U.S. Climate Change Science Program report states that abrupt climate change is unlikely to happen over the next century, scientists announced Tuesday at the annual meeting of the American Geophysical Union. But the consequences could still be severe.

The Montreal Protocol, signed in 1987, helped keep the ozone hole over Antarctica from growing. Now, new research suggests that the treaty also prevented significant regional climate change.

With sea levels projected to rise, the tiny island nation of Maldives is in desperate straits. So its new president has announced a radical plan — to use tourist dollars to buy a new homeland.

Arctic soils may contain more organic carbon than once thought — and that carbon could escape to the atmosphere as temperatures warm.
