Despite everything, there are now record quantities of greenhouse gases in the atmosphere, according to UN agency the World Meteorological Organization.
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.
North American forests might be more use than expected at slowing the pace of climate change.
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.
There's been a sharp rise in global CO2 emissions over the last ten years, despite reductions by industrialized countries.
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).
Climate change is loading the dice in favor of extreme weather events like Huricane Irene, a new report suggests.
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.
Thawing permafrost could release billions of tons of carbon into the atmosphere by the end of this century, further accelerating global warming.
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.
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.
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.
As carbon dioxide in the atmosphere increases, the soil releases ever more of two other potent greenhouse gases, new research has found.
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.
Former Pennsylvania GOP senator Rick Santorum wants you to know he doesn't believe in any of that "junk science" global warming stuff.
It's been known for a while that global warming speeds the decomposition of organic matter in soil, speeding up carbon dioxide release.
High levels of greenhouse gases could kill off life in the oceans in the same way as happened during prehistoric times, geologists warn.
