The NASA Worldview satellite image below shows Arctic sea ice on June 29, 2023, with the North Pole on the left.  The Uni of Bremen image below shows Arctic sea ice thickness on June 28, 2023. The danger is that, as El Niño strengthens, there will be massive loss of Arctic sea ice over the coming months, with water in the Arctic Ocean heating up strongly due to loss of the latent heat buffer and loss of albedo , while huge amounts of ocean heat keep entering the Arctic Ocean from the Atlantic Ocean and the Pacific Ocean. The image below shows that the North Atlantic sea surface temperature was 23.5°C on June 28, 2023 (on the black line), 0.9°C higher than the 22.6°C on June 28, 2022 (on the orange line). A record high of 24.9°C was reached on Sept. 4, 2022, even while La Niña was suppressing the temperature. This time, there's an El Niño.  The image below, adapted from NOAA , shows ocean heat moving toward the Arctic along the path of the Gulf Stream on June 25, 2023, while ...

The image below, created by Eliot Jacobson , shows the North Atlantic sea surface temperature anomaly through June 20, 2023 (versus 1982-2023 mean). The image below, created by  Eliot Jacobson , shows the North Atlantic sea surface temperature on June 21, for the years 1982-2023. The image below shows that the North Atlantic sea surface temperature was 23.3°C on June 21, 2023 (on the black line), 0.9°C higher than the 22.4°C on June 21, 2022 (on the orange line). A record high of 24.9°C was reached on September 4, 2022, even while La Niña then was suppressing the temperature, whereas now there's an El Niño. [ click on images to enlarge ] Global sea ice extent was at a record low for the time of year on June 23, 2023, i.e. only 21.57 million km², as illustrated by the image below. [ click on images to enlarge ] Contributing to this is very low Antarctic sea ice extent. The image below shows Antarctic sea ice extent up to June 23, 2023. Values in the column on the left are...

The NASA Worldview satellite image below shows Arctic sea ice on June 18, 2023. While the sea ice on much of the picture is shrouded in clouds, Arctic sea ice clearly is in a poor condition, even close to the North Pole (on the bottom left of the image below).  The Uni of Bremen image below shows Arctic sea ice thickness on June 18, 2023. The danger is that, as El Niño strengthens, there will be massive loss of Arctic sea ice over the coming months, with water in the Arctic Ocean heating up strongly due to loss of the latent heat buffer and loss of albedo , while huge amounts of ocean heat keep entering the Arctic Ocean from the Atlantic Ocean and the Pacific Ocean. The image below shows that the North Atlantic sea surface temperature was 23.1°C on June 18, 2023 (on the black line), 0.8°C higher than the 22.3°C on June 18, 2022 (on the orange line). A record high of 24.9°C was reached on Sept. 4, 2022, even while La Niña was suppressing the temperature. This time, there's an El N...

The NASA Worldview satellite image below shows Arctic sea ice in a poor condition on June 16, 2023, all the way up to the North Pole (on the bottom left of the image below). There is open water near the Franz Josef Archipelago, some 1000 km from the North Pole (on the right side of the image below). Clouds prevent a clearer view of the sea ice. The Uni of Bremen image below shows Arctic sea ice thickness on June 15, 2023. The danger is that, as El Niño strengthens, there will be massive loss of Arctic sea ice over the coming months, with water in the Arctic Ocean heating up strongly due to loss of the latent heat buffer and loss of albedo , while huge amounts of ocean heat keep entering the Arctic Ocean from the Atlantic Ocean and the Pacific Ocean. Furthermore, the Jet Stream is strongly deformed, threatening to result in heatwaves that extend over the Arctic Ocean and that cause hot water from rivers to enter the Arctic Ocean, while storms accelerate the flow of ocean heat in...

The World daily 2-meter Air Temperature (90-90°N, 0-360°E) was 16.77°C on June 9, 2023, an anomaly of 0.9°C for that day. The highest temperature on record is 16.92°C, and it was reached on August 14, 2016, and the anomaly for that day was only 0.75°C.  The record high of 16.92° actually was a tie between August 13, 2016, August 14, 2016, and July 24, 2022. That latter date is important, since the record high temperature was reached even while there was a strong La Niña, suppressing the temperature. This time, we're in an El Niño , so we can expect even higher temperatures over the next few weeks. The highest anomaly on record was reached on February 28, 2016, when there was a strong El Niño and the anomaly was 1.15°C. Note that these anomalies are compared to the mean temperature for that day in NOAA's NCEP CFSv2 .  The above image, from an earlier post , uses monthly NASA Land+Ocean temperature anomalies versus 1886-1915 that are further adjusted by 0.99°C to reflect ocea...

The above image shows high temperature anomalies over the Arctic on June 3, 2023.  The above image shows sea surface temperature on the North Atlantic (0-60N, 0-80W) depicted as anomalies, reaching 1.04°C above 1982-2023 on June 8, 2023.  The situation is especially critical in the North Atlantic, as vast amounts of ocean heat in the North Atlantic are moving toward the Arctic, threatening to cause rapid melting of Arctic sea ice and thawing of permafrost. The above image shows the same data for sea surface temperature on the North Atlantic (0-60N, 0-80W) reaching 22.5°C on June 7, 2023 (on the black line), 0.6°C higher than the 21.9°C on June 7, 2022 (on the orange line).  The comparison with 2022 is important, as the North Atlantic sea surface temperature reached a record 24.9°C on Sept. 4, 2022, even while there was a strong La Niña, suppressing the temperature. This time, we have an El Niño, as illustrated by the NOAA image on the right.  [ click on images to en...
