Arctic Posts Second Warmest Year On Record In 2018, NOAA Says (reuters.com)
According to a new report released on Tuesday by the U.S. National Oceanographic and Atmospheric Administration, the Arctic had its second-hottest year on record in 2018. "Arctic air temperatures for the past five years have exceeded all previous records since 1900," according to the annual NOAA study, the 2018 Arctic Report Card, which said the year was second only to 2016 in overall warmth in the region. Reuters reports: The study said the Arctic warming continues at about double the rate of the rest of the planet, and that the trend appears to be altering the shape and strength of the jet stream air current that influences weather in the Northern Hemisphere. "Growing atmospheric warmth in the Arctic results in a sluggish and unusually wavy jet-stream that coincided with abnormal weather events," it said, noting that the changing patterns have often brought unusually frigid temperatures to areas south of the Arctic Circle. Some examples are "a swarm of severe winter storms in the eastern United States in 2018, and the extreme cold outbreak in Europe in March 2018 known as 'the Beast from the East.'"
The medieval warm period. Really. C'mon. Don't want to go back to the dinosaurs as usual to show just how warm earth can be and still sustain life?
But ok. The MWP. First of all, even during the MWP it wasn't as warm as it is today. It was about 0.2 to 0.4 degrees Celsius warmer than before. Today we're at about 1.0 degrees warmer than it was in the 800s. Second, the MWP was not an uniform climate change as we experience today. It was mostly a localized phenomenon with various areas experiencing warmer periods during different times in those 300ish years.
In other words, there's a reason why even the most harebrained deniers don't use it. Stick with the dinosaurs, back then it was at least warmer than it is today.
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
