Today’s outlook for climate trends is a good-news, bad-news situation for the Pacific Northwest.
First, the bad news: NASA and the National Oceanic and Atmospheric Administration say 2016 ranked as the hottest year on record in terms of global mean temperatures.
NOAA said the year’s average temperature across global land and ocean surfaces was 58.69 degrees Fahrenheit, which is 1.69 degrees F above the 20th-century average and 0.07 degrees F above the previous record, set in 2015.
NASA used a slightly different set of figures, including more readings from the Arctic, to determine that last year’s global average was 1.78 degrees above the 20th-century average and 0.22 degrees above 2015. By either measure, the average is the highest since modern recordkeeping began in 1880.
