26 February 2018, Sydney Morning Herald, ‘Really extreme’ global weather event leaves scientists aghast. Climate scientists are used to seeing the range of weather extremes stretched by global warming but few episodes appear as remarkable as this week’s unusual heat over the Arctic. Zack Labe, a researcher at the University of California at Irvine, said average daily temperatures above the northern latitude of 80 degrees have broken away from any previous recordings in the past 60 years.

17 February 2018, Independent, Global sea ice hits record low for January as the annual polar melting period expanded. The world’s sea ice shrank to a record January low last month as the annual polar melting period expanded, experts say. The 5.04 million square miles of ice in the Arctic was 525,000 square miles below the 1981-to-2010 ice cover average, making it the lowest January total in satellite records, according to the US National Snow and Ice Data Center (NSIDC). Combined with low levels in the Antarctic, global sea ice amounted to a record low for any first month of the year, the organisation concluded. The news comes just days after researchers from the University of Colorado Boulder said the rate at which sea levels are rising was increasing every year, driven mostly by accelerated melting in Greenland and Antarctica. The NSIDC, a respected authority on the Earth’s frozen regions, which researches and analyses snow, glaciers and ice sheets among other features, said that ice in the Arctic Ocean hit “a new record low” at both the start and end of last month. In an online post, the group said: “January of 2018 began and ended with satellite-era record lows in Arctic sea ice extent, resulting in a new record low for the month. Combined with low ice extent in the Antarctic, global sea ice extent is also at a record low.” Read More here

13 February 2018, NASA Goddard Institute, The rate of global sea level rise has been accelerating in recent decades, rather than increasing steadily, according to a new study based on 25 years of NASA and European satellite data. This acceleration, driven … Continue reading →

11 January 2018, Yale Climate Connections, Bomb-cyclone’ weather in a warming world. This month’s Yale Climate Connections ‘This is not Cool’ video offers a plain-English science-based response to the inevitable ‘So much for climate change’ weather riddle. With New England, much of the middle Atlantic region, and parts of the southeast extending well into Florida suffering through late December-, early January-punishing cold temperatures, and in a number of places, record night-time lows and heavy snowfalls – the inevitable “so much for global warming” argument seemed certain to arise. On the one hand there were analytical news stories such as The Washington Post’s Capital Weather Gang’s story headlined “Historic ‘bomb cyclone’ unleashes blizzard conditions from coastal Virginia to New England. Frigid air to follow.” There also was President Trump’s “we could use a little more of that good old global warming” tweet from his “balmy Mar a Lago” residence looking forward to a frigidly cold New Years Eve dropping of the 2018 ball at Times Square in New York City. So how then to explain such not-at-all-unusual experience of cold weather temperatures even as the global temperatures continue rising? (One can safely anticipate having to explain cool summer-time daily temperatures in some places as the world continues warming.) To some extent, it’s a simple question of needing to repeatedly explain the difference between weather (short term and local) and climate (long term and global). Read More here
