Newt Gingrich was a little off-message during CNN's climate change debate Monday night. He was supposed to be pointing to the record-breaking cold temperatures as evidence that global warming is a hoax, like his fellow climate deniers.
But in lieu of wasting time denying the rise of global temperatures, the former House speaker and self-proclaimed "amateur paleontologist" instead chose a different tack: suggesting that it's arrogant of humans to act like we can or should control Earth's thermostat.
Small volcanic eruptions account for part of the global warming slowdown since 2000, a new study suggests.
Until now, the climate impacts of small volcanic blasts were overlooked because their planet-cooling particles cluster below the reach of satellites, scientists reported Oct. 31 in the journal Geophysical Research Letters. It turns out, satellites were missing about 30 percent of these particles, called aerosols, the study found.
