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 sea s
