Cattle generate twice as much methane as the EPA supposed, according to a new report. The study's findings may also change assumptions about the safety of extracting natural gas, which consists primarily of methane.

Two different areas of Antarctica tell two very different stories about how climate change might be affecting ice melt. The data appear to confirm that climate change impacts can be very local.
A new study from Chinese and Canadian researchers links the burning of fossil fuels to China's rise in its daily temperature spikes. China emits more greenhouse gas than the next two biggest carbon polluters – the US and India – combined.
Transatlantic flights will be bumpier by 2050 because of rising CO2 emissions, a new study finds. Turbulent episodes could double and the average strength of turbulence would also rise 10 to 40 percent.
The study, which also found the magnitude of the global temperature rise to be unmatched in 4,000 years, suggests that the current warming trend cannot be explained by naturally occurring temperature fluctuations.
Add to the long-studied global-warming perils of drought, insects, and wildfires, a new potential threat to the pinyon pine: dramatically lower production of seed-bearing cones.
A study suggests that human-caused and natural global warming episodes affect rainfall rates differently. The finding could help scientists better forecast what's ahead.
A tornado threat was posted Tuesday. Tornadoes are unusual in winter, but a large swath of the country was under a tornado watch, with some areas facing a tornado warning.
Andes glaciers, a vital source of fresh water for tens of millions of South Americans, are retreating at their fastest rates in more than 300 years, according to the most comprehensive review of Andes ice loss so far.
Global warming 'has had a role' in making 2012 the hottest ever recorded in the lower 48 states, says a US climatologist. The average temperature was 54.3 degrees F., a full degree higher than the previous annual record.
Average temperatures in West Antarctica rise 4.3 degrees since 1950s. The region's warming is nearly twice as much as expected and one of the most rapid on the planet.
