NOAA Climate Analyses and Statistics

Did you know that NOAA regularly publishes articles that summarize recent weather events and the state of the climate ( https://www.noaa.gov/topic-tags/climate-analyses-and-statistics )? Generally, articles are released about twice or three times a month, and contain information about significant weather events, climate statistics for the United States for the previous month, and notes about significant studies or papers which have been published about the state of the climate. See below for details about some recent articles!

Arctic Report Card: 12/10/2019

The Arctic Report Card is published annually and contains summaries of observations which are taken in this part of the globe which appears to be undergoing rapid changes. The parameters tracked are surface air temperature, snow cover, the Greenland Ice sheet, sea surface temperature, sea ice, Arctic Ocean Primary Productivity, and tundra greenness. The most recent report found that, among other things: there was near-record ice loss (measured in extent and magnitude) of the Greenland ice sheet, Arctic sea ice extent was at its second lowest level since satellite observations began tracking this in 1979, and changes in the habits of certain Arctic fish species have been observed.

Climate change and extreme weather

A NOAA report dated December 9, 2019 summarized a paper published in the Bulletin of the American Meteorological Society which discusses whether extreme weather events of 2018 were linked to human-induced climate change. The paper summarizes 20 peer-reviewed publications which analyze extreme weather events around the globe and use both observations and modelling to determine whether a changing climate influenced these events.
