An uodate on Arctic ice - April 24, 2018

Arctic ice: April 2018 Update

24 April, 2018




On April 22nd, 2018, Arctic sea ice extent was only 13.552 million km², a record low for the time of year. In 1987, by comparison, sea ice extent wasn't below 13.574 million km² even on May 22nd.

Meanwhile, CO₂ (carbon dioxide) levels are rising, as illustrated by the image on the right, showing that hourly levels were above 413 ppm at Mauna Loa recently.

Fires are raging near the Amur River in East Siberia, where CO₂ levels reached as high as 973 ppm on April 18, 2018, as illustrated by the image below.


As the image below shows, carbon monoxide levels at that spot were as high as 43,240 ppb on April 18, 2018.


The NASA Worldview image below shows the fires and burn scars on April 19, 2018.
