[ discussed at facebook ] The above image illustrates how much hotter October 2023 was in the Northern Hemisphere, compared to October in other years. The temperature in October 2023 was more than 2°C above October in 1880-1920, in the Northern Hemisphere, even with 3 years smoothing. Note that 1880-1920 is not pre-industrial, when using…
The bold black line at the top of the image below, adapted from Climate Reanalyzer, shows extremely high sea surface temperatures up to September 13, 2023, much higher than in any previous year on record. The image below, created with NASA data, shows why these extremely high sea surface temperatures are so worrying. The image…
The above image, adapted from Climate Reanalyzer, shows that on September 8, 2023, the North Atlantic sea surface reached a new record high temperature, of 25.4°C, even higher than the record reached the day before. The situation is critical! More heat entering the Arctic Ocean threatens to destabilize hydrates and cause huge amounts of methane…
The Blob is a large mass of water with relatively high heat content, floating at the surface and underneath the surface of the North Pacific Ocean. The Blob did appear several times before, including in 2016, which was a strong El Niño year. The above image shows high sea surface temperature anomalies in the North Pacific…
Arctic Ocean heating up There are at least five mechanisms that cause the water of the Arctic Ocean to heat up, as described below. 1. Direct Heat. Heat from sunlight directly reaches the surface, i.e. the sea ice or the water of the Arctic Ocean. The August 8, 2023, image on the right, from Climate…
On July 25, 2023, the North Atlantic sea surface reached a record high temperature of 24.9°C. The previous record was in early September 2022, when the temperature peaked at 24.89°C, according to NOAA scientist Xungang Yin and as illustrated by the image below. In previous years, a La Niña was suppressing temperatures, whereas El Niño is…
World temperatures during each of the past 16 days have been higher than they have been for millions of years. Moreover, the temperature is now rising faster than during any period before, and could rise 18.44°C (versus pre-industrial) by the year 2026. In each of the past 16 days, the temperature has been higher than the peak temperature…
