Arctic temperatures soar 45 degrees above normal, flooded by extremely mild air on all sides

SOURCE: Washington Post DATE: February 22, 2018 SNIP: While the Eastern United States simmered in some of its warmest February weather ever recorded Tuesday and Wednesday, the Arctic is also stewing in temperatures more than 45 degrees above normal. This latest huge temperature spike in the Arctic is another striking indicator of its rapidly transforming climate. On Monday and Tuesday, the northernmost weather station in the world, Cape Morris Jesup at the northern tip of Greenland, experienced more than 24 hours of temperatures above freezing according to the Danish Meteorological Institute. The Danish Meteorological Institute wrote that only twice before had it measured temperatures this high during February at this location, in 2011 and 2017. It is a mere 400 miles from the North Pole. The warmth over Alaska occurred as almost one-third of the ice covering the Bering Sea off Alaska’s West Coast vanished in just over a week during the middle of February, InsideClimateNews reported. Brian Brettschneider, a climatologist based in Alaska, posted that the overall sea ice extent on Feb. 20 was the lowest on a record by a long shot. As of Friday, the whole region had spiked more than 35 degrees (20 Celsius) above normal, which Labe called a “truly remarkable event” and the warmest in February ever...
Astounding Warmth In the Eastern U.S. and Across the Arctic

Astounding Warmth In the Eastern U.S. and Across the Arctic

SOURCE: AGU DATE: February 22, 2018 SNIP: The big weather story in February has not been snow, but the astounding heat. The Danish Meteorological Institute has a station on the Arctic Ocean in Northern Greenland. While in total darkness, and just 400 miles from the North Pole, the temperature there climbed above freezing Tuesday [Feb 20, 2018]! And then there’s the global sea ice extent, which has continued to track at the lowest levels measured for most of the NH winter. The Arctic sea ice is also at record lows at the time of maximum winter extent, and it’s not even a close call on that record.Temperatures north of 80° have been as warm as 10-15 °C ABOVE normal since the beginning of the...
Every Other Summer Will Shatter Heat Records Within a Decade

Every Other Summer Will Shatter Heat Records Within a Decade

SOURCE: Motherboard and Earth’s Future Open Access Journal DATE: November 1, 2017 SNIP: Think of the stickiest, record-hot summer you’ve ever experienced, whether you’re 30 or 60 years old. In 10 years or less, that miserable summer will happen every second year across most of the US and Canada, the Mediterranean, and much of Asia. By the 2030s, every second summer over almost all of the entire Northern hemisphere will be hotter than any record-setting hot summer of the past 40 years, the study found. By 2050, virtually every summer will be hotter than anything we’ve experienced to date. Record hot summers are now 70 times more likely than they were in the past 40 years over the entire Northern hemisphere, the peer-reviewed study...
Warm winters, scorching summers: New maps project impact of climate change

Warm winters, scorching summers: New maps project impact of climate change

SOURCE: National Post DATE: October 26, 2017 SNIP: Is this the end of the Great Canadian winter? A new report says that even if greenhouse gas emissions are reduced, all of Canada is projected to get warmer by the end of the century, while the number of 30 C plus days per year are predicted to “explode” under the current global warming trajectory. Overall, the globe is projected to warm by two to three degrees Celsius by 2051 to 2080, compared to 12 degrees or more for some places in the Canadian High Arctic, assuming the high-carbon future we’re trending towards, Smith said in an email. Toronto’s summers are projected to warm by four degrees Celsius by 2051 to 2080 in a high-carbon scenario; in comparison, its winters are projected to warm five degrees Celsius. Churchill summers will warm by 3.5 degrees Celsius; its winters by nine...
Australian cities to have 50C summer days by 2040, study says

Australian cities to have 50C summer days by 2040, study says

SOURCE: The Guardian DATE: October 3, 2017 SNIP: Even if the Paris agreement to limit the global temperature rise to below 2C is met, summer heatwaves in major Australian cities are likely to reach highs of 50C by 2040, a study published on Wednesday warns. The lead author of the study, the climate scientist Dr Sophie Lewis, said Sydney and Melbourne could expect unprecedented summer temperatures of 50C under two degrees of global warming. Governments needed to start thinking about how the public transport system would cope during peak hour in extreme temperatures, how emergency departments would respond to increased demand from elderly people and others vulnerable to heatstroke, and how energy requirements would be met during peak temperatures, she said. “I don’t think we have any plans in place that would be adequate to withstand days of 50 degrees and it is another urgent warning to our leaders and all levels of government that we need a strong plan to cut commissions and deal with climate...
