By evaluating historical climate records, observational and projection data, an international team of researchers found a “pushing and triggering” mechanism that has driven the Arctic climate system to a new state, which will likely see consistently increased frequency and intensity of extreme events across all system components – the atmosphere, ocean and cryosphere – this […]
KAKTOVIK, ALASKA —In the Arctic, the impact of climate change is happening at an accelerated pace, with temperatures rising two to four times faster than the global average. “It’s called the polar amplification,” explains Vladimir Romanovsky, a geophysicist at the University of Alaska in Fairbanks. “Snow and ice reflect lots of energy back to space […]
The Arctic has experienced the warming effects of global climate change faster than any other region on the planet. Scientists at the Scripps Institution of Oceanography have developed a new theory aided by computer simulations and observations that helps explain why this occurs. A team led by Scripps researcher Emma Beer observed the changes taking place […]
