Any Way You Look at It, This Government Report on Climate Change Is Really Bad News
The National Oceanic and Atmospheric Administration and the American Meteorological Society say that even if greenhouse gas emissions ended immediately the oceans would continue to warm for centuries.
Hungry Polar Bears Are Getting Screwed by Shrinking Arctic Sea Ice
Scientists thought hungry polar bears went into 'walking hibernation' if they couldn't find food — but new research says that's not the case.
It May Be Even Worse for the Polar Bears Than Previously Thought
Two new US government reports paint a very bad picture for polar bears, which are under threat due to diminished sea ice extent in the Arctic, a region that is warming at twice the rate as the rest of the world.

Temperatures for the month were over seven degrees warmer than the 20th-century average — the latest in a two-year streak of broken temperature and precipitation records.
It Was Warmer in Antarctica Than in New York City Last Week — and That's Not Even the Bad News
Rates of sea ice melt are higher than previously seen and could bring about dangerous levels of sea-level rise.
The Extent of Winter Sea Ice in the Arctic Hit a Record Low This Year
Less Arctic ice means more dark, open-ocean water that absorbs additional heat, melting yet more ice, and so on in what is a quintessential climate change feedback loop.
Animation Shows Alarming Trend in the Arctic Ocean
The amount of sea ice in the Arctic that is more than a year old has been decreasing since the mid-1980s, meaning the ice pack is becoming more vulnerable to warming ocean temperatures.
Why Global Warming Means a Snowier Eurasia
It may seem like a paradox, but a hotter Arctic can lead to colder winters across Eurasia.
