Greenhouse gases hit record high

Despite everything, there are now record quantities of greenhouse gases in the atmosphere, according to UN agency the World Meteorological Organization.

BEST study fails to satisfy global warming skeptics

A research project founded by a climate change skeptic has concluded that the planet is getting warmer, with land temperatures rising by one degree Celcius since the 1950s.

Forests soak up more CO2 than thought

North American forests might be more use than expected at slowing the pace of climate change.

CIA classified global warming as top secret

Global warming is simply not happening, folks, and if it is, then it's classified information that must be kept secret by the CIA at all costs.

CO2 emissions reach record levels

There's been a sharp rise in global CO2 emissions over the last ten years, despite reductions by industrialized countries.

Deep oceans store heat from global warming - for a while

The deep oceans can absorb enough heat to mask the effect of global warming for a decade at a time, say scientists at the National Center for Atmospheric Research (NCAR).

Extreme weather events on the rise, says climate group

Climate change is loading the dice in favor of extreme weather events like Huricane Irene, a new report suggests.

Cutting soot emissions could be climate quick fix

Reducing soot emissions from diesel engines and other sources could be the fastest, most economical way to slow the melting of Arctic sea ice, researchers say.

Melting permafrost could ramp up global warming

Thawing permafrost could release billions of tons of carbon into the atmosphere by the end of this century, further accelerating global warming.

Global warming 'could trigger alien attack'

Maybe NASA believes that the little green men really are green - one of its scientists has collaborated on a report suggesting that the Earth's rising levels of greenhouse gases could provoke an alien attack.

Al Gore flips out over global warming

South Park fans probably knew this day was inevitable. Yes, Al "ManBearPig" Gore has finally flipped out in public about his very favorite topic: global warming.

Atmospheric aerosols slow global warming by a third

Airborne particles from volcanoes and the burning of fossil fuels have reflected enough sunlight to offset about a third of the current climate warming caused by carbon dioxide over the past decade, says the NOAA.

Soil microbes amplify global warming

As carbon dioxide in the atmosphere increases, the soil releases ever more of two other potent greenhouse gases, new research has found.

Chinese coal use slows global warming

The decrease in global warming between 1998 and 2008 - often cited as evidence against man-made climate change - was actually caused by an increase in coal use in China, a study has found.

Santorum spouts off on climate change

Former Pennsylvania GOP senator Rick Santorum wants you to know he doesn't believe in any of that "junk science" global warming stuff.

Global warming may help trees store more carbon

It's been known for a while that global warming speeds the decomposition of organic matter in soil, speeding up carbon dioxide release.

Greenhouse gases threaten mass mortality in oceans

High levels of greenhouse gases could kill off life in the oceans in the same way as happened during prehistoric times, geologists warn.

Is global warming a bigger threat than Skynet?

Well, hey now! Al "ManBearPig" Gore must be on vacation, because Avatar director James Cameron has taken it upon himself to warn humankind about the dangers of global warming.

Contrails warm world more than CO2 emissions

Aircraft contrails do more to warm the planet than their exhaust fumes, a new study has found.

Intense global warming was frequent in ancient past

Frequent periods of intense global warming took place in the distant past, say researchers at UC San Diego's Scripps Institution of Oceanography.
