    “Last year was the second hottest year on record worldwide, behind 2016, according to a European Union climate monitoring program.” (Yale School of Forestry & Environmental Studies) http://e360.yale.edu/digest/its-official-2017-was-the-second-hottest-year-on-record Comparable results have been obtained by C3S from a reanalysis dataset produced by the Japan Meteorological Agency (JMA). “While 2016’s temperatures were boosted by an intense El Niño event in the Pacific Ocean, C3S said that 2017 saw very little influence from that event. Rather, “2017 was close to the warmest year on record despite cooling La Niña conditions both early and late in the year” https://climate.copernicus.eu/news-and-media/press-room/press-releases/2017-extends-period-exceptionally-warm-years-first-complete

    National Weather Service Boston 10:50 AM – 4 Jan 2018: “We do not recommend going out and floating on icebergs; this is a very dangerous situation along the coastline with major flooding ongoing, peoples homes & other infrastructure becoming inundated and damaged; please observe should you have to from a safe location” https://twitter.com/NWSBoston/status/948990004327526402
    Get used to saying ‘bomb cyclone’ : Wild storms like this week’s massive coastal cyclone will be part of winters in the Anthropocene.” http://grist.org/article/get-used-to-saying-bomb-cyclone-this-is-our-climate-now/ “…Atlantic Ocean temperatures right offshore were as much as 7 degrees Fahrenheit warmer than normal for early January, causing hurricane-force winds and snow squalls so intense they fired off lightning bolts over parts of New York and Rhode Island. Forecasters dispatched a Hurricane Hunter airplane to investigate the storm.
    All this atmospheric drama overshadowed two other storms underway at the same time. A sprawling cyclone even stronger than the “bomb cyclone” plowed past Alaska, where the ocean should be covered in ice this time of year. In Europe, a powerful ocean storm made landfall in the British Isles. It arrived with a cold front whose strong winds fanned midwinter wildfires on the French Mediterranean island of Corsica and closed down ski slopes in the Alps for fear of avalanches.
    For some, all this evidence of an overheating world is too much to accept.”

    “NOAA recaps 2017’s near-biblical collection of weather extremes” https://arstechnica.com/science/2018/01/noaa-weather-events-made-2017-a-year-of-extremes/ The figures for 2017’s global temperatures aren’t out yet, but data from earlier months indicate it will involve a small drop after two years of record-setting heat. NOAA, however, has run the numbers on 2017’s impact on the US, finding it to be the third warmest on record and associated with lots of extreme weather events. Amazingly, NOAA’s brief report on 2017’s climate managed to mention all of this without once mentioning climate change.

    “Jet stream changes since 1960s linked to more extreme weather” (University of Arizona 1/12/18) https://www.eurekalert.org/pub_releases/2018-01/uoa-jsc011118.php “…The heat waves and drought that are related to such jet stream extremes happen on top of already increasing temperatures and global warming — it’s a double whammy.”
    Extreme summer weather events in the American Midwest are also associated with extreme northward or southward movements of the jet stream, the authors write. “We studied the summer position of the North Atlantic jet. What we’re experiencing now in North America is part of the same jet stream system,” Trouet said. This winter’s extreme cold and snow in the North American Northeast and extreme warmth and dryness in California and the American Southwest are related to the winter position of the North Pacific Jet, she said.
    The paper, “Recent enhanced high-summer North Atlantic Jet variability emerges from three-century context” is scheduled for publication in Nature Communications on Jan. 12.
