Hashtags won't fix this. At some point we need to take action, to stand up and be counted against the brute force of the oil companies, lobbyists and politicians who willingly pollute our climate system.

To make a complex story simple, polar bears are threatened by habitat loss. We may hold onto polar bears as a species to the end of the century, but this is predicated on many hopeful elements.

There is no contradiction for global warming to cause dramatic sea ice loss in the Arctic and a slight expansion in the Antarctic. There is no doubt in my mind that the implications for polar bears habitat loss are serious and sobering.

This summer's record low sea ice extent has prompted speculation about how polar bears will be affected. Because polar bears depend on sea ice to catch seals, less sea ice can only be bad for polar bears. But it's not just this year's record low that is cause for concern.

WASHINGTON (AP) — The ice goes on seemingly forever in a white pancake-flat landscape, stretching farther than ever before. And yet in this confound...

If greenhouse gases continue to rise, all models predict that the planet is headed to a future with an Arctic that is ice-free in the summer. The predictions of when this will occur vary by model, from as soon as a decade or two from now to closer to the end of the century.

It's now official: The 2012 Arctic summer sea ice melt blows past the previous record low. According to the National Snow and Ice Data Center, "Arctic...

There are many questions to be asked about why our demand for hydrocarbon-based fuels is so great that we are now drilling for hydrocarbons in some of the most harsh conditions in the world.

Melting, cracking, splitting and calving in Earth's cryosphere may be the most dramatic embodiments of the climatic change. Why should all this melting ice matter to us? Here are a few reasons.

Climate change spares no one. Not even the adorable.

As of January 10, 2012 only 14.7 percent of the U.S. was covered by snow compared to 61.7 percent at the same time last year.

Has the warming trend slowed in the 2000s? Yes and no.

It all really boils down to a simple equation: sea ice + seals on the sea ice = healthy polar bear populations. Take away the ice and polar bears can't hunt seals and their populations decline.

You have probably heard about melting Arctic ice and the drastic decrease in glacier size. And while you may be aware that the increase in greenhouse gases is to blame, at least in large part, you may not realize that a substance called black carbon is an accomplice.
