World The Arctic Is Warming Nearly Four Times Faster Than the Rest of the World
“There were tears”: Kylie Minogue’s emotional post after Neighbours finale rumours were finally debunked
Kylie Minogue has revealed “there were tears” as she filmed and watched the emotional Neighbours finale last week. Australia's pop princess returned to her breakout role as Charlene Robinson for the 90-minute special episode, which saw the soap come to an end after 37 years. Reflecting on the finale and all the years of TV leading up to it, Kylie said the show will always hold a special place in her heart. © Provided by Are Media Pty Ltd Kylie Minogue shared a stunning collage of moments from her Neighbours history.
The Arctic is warming like never before, nearly four times faster than the rest of Earth—and twice as fast as scientists previously thought. Finnish researchers drew from observed climate data from the past four decades and published their discovery of this systematic undercount.
“Numerous recent studies report the Arctic having warmed either almost twice, about twice, or more than twice as fast as the global average. However, the warming ratios reported in these
Beluga whale spotted in France's Seine river
A Beluga whale, a protected species usually found in cold Arctic waters, has been seen in France's Seine river, with authorities urging people to keep their distance to avoid distressing the animal. Officials in the Eure department of Normandy said late Wednesday that images suggested it was a beluga separated from its pod, though they did not specify its size nor where exactly it was seen. An adult beluga can reach up to four metres (13 feet) in length, and while they migrate away from the Arctic in the autumn to feed as ice forms, they rarely venture so far south.
and many other studies have usually been only referenced from older, possibly outdated, estimates and have not included recent observations,” the authors wrote in the study.
The reason the Arctic warms faster than the rest of the globe—a phenomenon known as—has to do with a number of factors we’re still trying to understand. Theorized about as early as 1896, Arctic amplification seems to rely in part on sea ice melting. When the bright ice gives way to darker-colored water, polar environments are less able to reflect heat from the sun and end up absorbing it at higher rates. Other factors that may contribute to Arctic amplification include a lack of heat-absorbing thunderstorms, the on snow, and increases in .
Frozen US-China cooperation presents new hitch for global warming
Beijing is freezing its cooperation with Washington on global warming, but experts are hoping that, for the sake of humanity, the cold spell between the world's two largest emitters is only temporary. The temporary US withdrawal has nonetheless been accompanied by backtracking on domestic and foreign climate policy, experts say. China's announcement, on the other hand, is "certainly not a withdrawal from the world stage on climate issues or a rejection of climate action," David Waskow, director of the World Resources Institute's international climate initiative, told AFP.
In the recent study, the researchers averaged observed temperatures over time from four different sources in a range of Arctic locations. Depending on where they considered the southern bound of the Arctic to be, their estimates for the average rate of warming compared to the rest of the globe varied from three to four times as fast. But they found the region of the Arctic Ocean near Svalbard to be warming seven times faster than the rest of the world, or up to 1.25ºC per decade.
By comparing the observed data to simulations from standard climate models, the researchers made another disquieting discovery: The models struggled to simulate four-fold Arctic amplification.run on massive supercomputers and are updated every few years to more realistically simulate Earth’s conditions. Based on their results, the researchers proposed that tomorrow’s models should aim to understand and more accurately simulate Arctic amplification.
But one change can be made immediately: The old metric that suggested Arctic warming was only two times faster than the rest of the planet, the researchers wrote, “clearly underestimates the situation during the recent 43 years.”
