Data from NASA's Curiosity rover has revealed the Martian environment lacks methane. This is a surprise to researchers because previous data reported by U.S. and international scientists indicated positive detections. The roving laboratory performed extensive tests to search for traces of Martian methane.
Methane is everywhere, and that’s pretty bad news for our planet. Thanks to gassy cows, the natural gas boom, and lots and lots of garbage rotting in our landfills, the amount of methane in the atmosphere has more than doubled since the industrial revolution.
Researchers say they've conducted the first reconnaissance of a distant planetary system, collecting the spectra of four red exoplanets which orbit a star 128 light years away from Earth.
It could take as little as a 1.5 degree rise in global temperature to thaw Siberia permanently, potentially releasing catastrophic levels of cartbon dioxide and methane from the soil.
The permafrost covering almost a quarter of the northern hemisphere contains twice as much carbon as is currently in the atmosphere, and could significantly amplify global warming should thawing accelerate as expected.
Data from NASA's Curiosity rover is helping to explain how Mars may have lost much of its original atmosphere, leaving it with 100 times less than Earth.
Human beings have been pumping methane into the atmosphere since Roman times, in enough quantity for it to show up in the Greenland ice sheet.
Scientists say they've finally established where the ocean's methane is coming from.
A massive reservoir of the greenhouse gas methane could be lying hidden beneath the Antarctic Ice Sheet, in a ticking time bomb for climate change.
NASA's Cassini spacecraft has come up with strng evidence that Saturn's moon Titan is hiding a layer of liquid water under its ice shell.
Disappointingly, scientists say they've been able to establish where the methane on Mars comes from - and it's not from living organisms.
British scientists have calculated that the amount of methane produced by farting dinosaurs would have affected the planet's atmosphere - and noticeably warmed the climate.
Saturn's giant moon Titan conceals a thick, smoggy atmosphere that is believed to be one of the most complex chemical environments in the solar system.
NASA scientists have detected large releases of methane - a highly potent greenhouse gas - from the crumbling Arctic sea ice.
Despite everything, there are now record quantities of greenhouse gases in the atmosphere, according to UN agency the World Meteorological Organization.
Thawing permafrost could release billions of tons of carbon into the atmosphere by the end of this century, further accelerating global warming.
Well, the UFOlogists won't like it, but UCLA scienstists have come up with an explanation for the giant white arrow observed on the surface of Titan, Saturn's largest moon - and it's not an 'X marks the spot' from aliens.
There was a leveling off of the amount of methane in the atmosphere towards the end of the last century - and scientists can't agree on why it happened.
As carbon dioxide in the atmosphere increases, the soil releases ever more of two other potent greenhouse gases, new research has found.
Liquid methane has been raining down on Titan, say NASA scientists, who have observed the equatorial weather on Saturn's largest moon for the first time.
