Sea levels are rising 60 per cent faster than the UN's climate panel forecast, scientists warn. Satellite measurements show that sea levels are actually rising at an alarming rate of 3.2 mm a year compared to the estimate of 2 mm a year in the Intergovernmental Panel on Climate Change's fourth assessment report (AR4), researchers said.

In an opinion piece in Saturday’s New York Times titled “The Conversion of a Climate-Change Skeptic,” Muller writes: “Three years ago I identified problems in previous climate studies that, in my mind, threw doubt on the very existence of global warming. Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I’m now going a step further: Humans are almost entirely the cause.”

If you want a glimpse of some of the worst of global warming, scientists suggest taking a look at U.S. weather in recent weeks. Horrendous wildfires. Oppressive heat waves. Devastating droughts. Flooding from giant deluges. And a powerful freak wind storm called a derecho. These are the kinds of extremes climate scientists have predicted will come with climate change, although it's far too early to say that is the cause. Nor will they say global warming is the reason 3,215 daily high temperature records were set in the month of June.

New research provides compelling evidence that the last ice age was ended by a rise in temperature driven by an increase in atmospheric carbon dioxide.

Some states have introduced education standards requiring teachers to defend the denial of man-made global warming. A national watchdog group says it will start monitoring classrooms.

For the clueless or cynical diehards who deny global warming, it’s getting awfully cold out there. The latest icy blast of reality comes from an eminent scientist whom the climate-change skeptics once lauded as one of their own. Richard Muller, a respected physicist at the University of California, Berkeley, used to dismiss alarmist climate research as being “polluted by political and activist frenzy.” Frustrated at what he considered shoddy science, Muller launched his own comprehensive study to set the record straight. Instead, the record set him straight.

Many of Earth's species appear to be shrinking in size, a new study reports, and its authors think that's probably due to global warming.

New pictures reveal the extent to which a huge glacier in northern Greenland has broken up in just two years, claims a glaciologist.

China acknowledged on Tuesday it is the world's biggest emitter of greenhouse gases stoking global warming, confirming what scientists have said for years but defending its right to keep growing emissions.

The first decade of the 21st century was the warmest ever on Earth according to data released by scientists at NASA.
