(PhysOrg.com) -- A new study led by the U.S, National Oceanic and Atmospheric Administration (NOAA) shows that tiny particles that make their way all the way up into the stratosphere may be offsetting a global rise in temperatures due to carbon emissions. And while scientists cannot yet say with any certainty where exactly the particles are coming from, they are saying that they have confidence that such particles have likely muted global temperature gains by as much as a third of what they would have been. They team, led by John Daniel, a physicist at the NOAA Earth System Research Laboratory (ESRL) in Boulder, CO, has published their results in Science.

Did a comet wipe out woolly mammoths and an ancient Indian culture almost 13,000 years ago? Geologists have fiercely debated the topic since 2007. Now a new study says an extraterrestrial impact wasn't to blame, though the scientists who originally proposed the impact idea still aren't convinced.
