A 12-year pause in global warming, after 20 years of rapidly rising surface temperatures, has scientists probing for the reason. Volcanic eruptions and undersea heat storage are emerging as likely explanations.

New York City Mayor Michael Bloomberg laid out a multimillion dollar plan Tuesday to guard New York City against storms and the effects of global warming. Fueled by Superstorm Sandy last fall, the sweeping proposals for New York represent a sizeable step up in scale and urgency for Mayor Bloomberg.
A monitoring station in Hawaii has measured carbon dioxide levels of 400 parts per million, a concentration not seen on Earth since the Pleistocene Era.
An international study used tree rings and pollen to build the first record of global climate change, continent by continent, over 2,000 years.
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.
