ANCHORAGE – 
 
 A 101-year-old record was broken in Alaska Thursday — a high of 71 degrees was recorded in southeast Alaska, beating a record set in 1915. 
 
 The high temperature was recorded in Klawock, located northwest of Ketchikan on Prince of Wales Island. 
 
 The National Weather Service called it the “warmest official temp in Alaska in March.” The previous record was 69 degrees in Ketchikan. 
 
 Klawock wasn’t the only spot in the southeast Alaska setting records Thursday. 
 
 Juneau, Yakutat, Sitka and Ketchikan all set new record high temperatures for March 31, ranging from 65 degrees in Ketchikan to 57 degrees in Yakutat. 
 
 March 2016 had the warmest monthly average temperature on record for Juneau, Sitka, Klawock, Haines, Petersburg, Skagway and Ketchikan. 
 
 The high today of 71F at Klawock is, preliminarily, the warmest official temp in Alaska in March.

The sun had set for the season, temperatures were dropping, ice was growing rapidly. Winter was coming, right on schedule. And then, a few days ago, everything came screeching to a halt. Ice stopped forming. And then it actually started to melt, thanks to a sudden heat wave that blistered the region with temperatures 20 to 30 degrees Fahrenheit above average. For now, the mass of warm air doesn’t appear to be going anywhere. 
 
 That’s bad news for sea ice. Coverage in the Arctic was already at its lowest levels since researchers began using satellite data to measure it back in 1978. And as of November 19, Arctic sea ice was nearly 350,000 square miles below its extent in 2012, the last record-low year. The extreme weather has scientists scrambling to figure out what’s causing the historical temperatures, and more importantly, what their long-term impacts could be.

 “It’s absurdly warm over the Arctic Ocean right now and the question is, where the heck is all that heat in the ocean coming from?,” says Mark Serreze, director of the National Snow and Ice Data Center in Boulder, CO. “No one has a real handle on that yet.” 
 
 There are a few likely explanations. At this time of year, without the sun’s rays, the ocean begins to lose its heat in the form of infrared radiation. On its way to outer space, the radiation has to pass through the atmosphere, and water vapor and carbon dioxide and other greenhouse gases trap and absorb some of that radiation, heating up in the process. 
 
 That’s all pretty normal. But this year, atmospheric circulation patterns are bringing more warmth to the Arctic than usual. Last month, an unusually high pressure system centered over Scandinavia brought in a flow of warm southerly air between Greenland and Norway. At the same time, in the Pacific, an abnormally low pressure system formed just east of Russia, along the Kamchatka Peninsula. That drew in warm heat from the mainland up toward Alaska and the Bering Sea. With their powers combined, they blasted the Arctic with a heavy, sweaty dose of hot air. 
 
 This wouldn’t be such a big deal on its own, but warmer and more humid air increases the greenhouse effect. It becomes more and more difficult for the ocean to transmit heat away from its surface, and more and more difficult for ice to form. Which is one explanation for why Arctic sea ice cover continues to run at record low levels this late into the year. 
 
 The effects are being felt far below the 66th parallel. States in the Upper Midwest experienced their warmest falls ever, with temperatures running about 15 degrees warmer than average through the second week of November. Minnesota experienced the longest growing season ever recorded: 220 days. And the Twin Cities set a record for the latest frost in history. 
 
 On his weather nerd cult blog the Updraft, Minnesota Public Radio chief meteorologist Paul Huttner said that the Arctic “was broken.” Normally, northwest winds blow down from the Arctic over snow-covered ground and iced-over lakes before reaching the US. But this year bare ground all the way up the Arctic circle allowed the sun to warm the upstream air mass more efficiently (no snow means no albedo effect). “The Arctic is North America’s refrigerator,” Huttner says. “If it stops getting as cold as it should, the effects are felt far and wide. I always say that the Arctic is no Las Vegas. Whatever happens in the Arctic, doesn’t stay in the Arctic.” 
 
 Which is why climate scientists are gathering data points to try to understand what this anomaly means for the future. It’s too soon to tell if the extreme temperatures are part of a pattern or just an outlier, Serreze says. But if there’s one thing history teaches us, it’s that the Arctic is not as resilient as it once was. Thick layers of old sea ice are the Arctic’s buffer against rare weather events—and that kind of ice has been rapidly disappearing. In the 1980s, multiyear ice made up 20 percent of sea ice cover; today, it’s only 3 percent. As those numbers decline, the Arctic becomes more vulnerable to wide temperature fluctuations. 
 
 “Had that same pattern set up in 1980, the sea ice could have taken the punch,” say Serreze. “Now it can’t. And what we’ve learned is that the response of the ice to these extreme events is changing, and with it so are the odds. It loads the dice.” 
 
 Dear Arctic, may the odds be ever in your favor. ||||| Skip in Skip x Embed x Share CLOSE According to the National Weather Service, the average temperature for Death Valley in July was a blistering 107.4 degrees. Video provided by Newsy Newslook

 Hell on Earth: With an average temperature of 107.39 degrees in July, Death Valley set the record for hottest month at a single location in U.S. history. 
 
 Keep in mind that that number is an average of all the high and low temperatures. The average daily high temperature was an unbearable 119.6 degrees. 
 
 “It should be noted that this is the hottest average monthly temperature ever measured in the U.S. or, for that matter, anywhere in the Western Hemisphere,” Weather Underground weather historian Christopher Burt told the Capital Weather Gang. 
 
 It was not a world record, however: Climatologist Brian Brettschneider said the world record warm month was in August 2015, when King Khaled, Saudi Arabia, measured an average temperature of 107.44 degrees.

 And nights were no bargain in Death Valley last month: The temperature didn't drop below 89 degrees the entire month of July, the National Weather Service said. Three days, the overnight low temperature was over 100 degrees. 
 
 July's hottest day was the 7th, when Death Valley hit 127 degrees. It was also 127 on two June days. 
 
 Death Valley is a national park with no permanent residents except for a few park service staff and rangers. It is the hottest, driest and lowest of all U.S. national parks. 
 
 Several other cities set record warm months in the West, as did Miami, the weather service said. 
 
 We broke a record this July--the hottest month ever for Death Valley! 🔥🌡️ https://t.co/vBDMd2q1j7 — Death Valley NP (@DeathValleyNPS) August 2, 2017

– Alaska has experienced some unusual natural phenomena lately—including a burping volcano and a desperate need for snow—and it just took another turn into some more weather-related weirdness. Per the Alaska Dispatch News, the mercury at an airport in Southeast Alaska registered at 71 degrees on Thursday, which University of Alaska Fairbanks climate scientist Brian Brettschneider says set a record high for temps in March, beating out a peak of 69 degrees set in March 1915. "The fact that it's March—it's pretty amazing," a National Weather Service meteorologist in Juneau says. "It's a big deal." What scientists say has brought on this thermometer-busting breach in Klawock, which KTVA notes is northwest of Ketchikan on Prince of Wales Island, is a high-pressure ridge that Brettschneider tells the Dispatch News is "basically [like we] had a June or July air mass move in in March. If we had June or July sun, it would have been 80 degrees, but we didn't." Other towns have similarly recorded record highs, and the warm weather is, as of now, anticipated to continue through May. (Alaska also just had the weirdest murder plot in a while.)
