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. The image on the right shows that Mauna Loa's CO₂ hourly average level was above 413 ppm recently. The daily average CO₂ level reached 412.37 ppm on April 23, 2018.

Fires are raging near the Amur River in East Siberia, with associated high emissions, as illustrated by the images below.

Above image shows CO₂ levels reaching as high as 973 ppm on April 18, 2018. As the image below shows, carbon monoxide levels at that spot were as high as 43,240 ppb on April 18, 2018.

The NASA satellite image below shows smoke plumes of the fires and burn scars on April 19, 2018.
