Arctic sea ice coverage reached a record low last month
Earth continues to sweat it out, and last month was no exception. April 2019 was the second-hottest April on the record, which dates to 1880. The Arctic region wasn’t spared either, as sea ice coverage shrunk to a record low for the month.
Here are highlights from NOAA’s latest monthly global climate report:
Climate by the numbers
The average global temperature in April was 1.67 degrees F above the 20th-century average of 56.7 degrees F, making it the second-hottest April in the 140-year record behind April 2016. Last month also was the 43rd consecutive April and 412 consecutive month that saw above-average global temperatures.
Year to date I January through April
The period from January through April produced a global temperature 1.62 degrees F above the average of 54.8 degrees, which is the third-hottest YTD on record. The record-warm temperatures for the fourth-month period were registered in parts of Australia, southeastern Brazil, central Asia, the southern Atlantic and southwestern Indian oceans and the Barents, East China and Tasman seas.
More notable stats
Sea ice shrinks markedly at both poles: Average Arctic sea ice coverage (extent) in April was 8.4 percent below the 1981-2010 average – the lowest for April on record. The Antarctic sea ice extent was 16.6 percent below average, the third smallest for April on record.
Canadian coolness reached southward: Cooler-than-average temperatures were logged from January through April across much of Canada and the north-central U.S., about 3.6 degrees F below average.
