The Dubai’s COP-out denial conference – by Andrew Glikson – The issue, betrayed, is nothing more and nothing less than the future of a multitude of species on Earth, including Homo sapiens. Global temperature (relative to 1880-1920 mean for each month) for the 1997-98, 2015-16 and 2023-24El Ninos. The impact of El Nino on global…
[ discussed at facebook – click on images to enlarge ] The above image, created with Climate Reanalyzer data, shows the temperature anomaly (in °C) compared to the 1979-2000 mean. In blue are the years 1979-2022 and in black and white is the year 2023 through December 3, 2023. A trend is added in pink…
[ 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 above image, adapted from NASA and the image below, adapted from Climate Reanalyzer and using the same baseline, illustrate the September 2023 temperature anomaly. September 2023 was the month with the highest temperature anomaly on record. What contributed to this? El Niño The temperature rose about 0.5°C from November 2022 to March 2023, and this occurred…
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…
Temperatures are high Globally, temperatures have been at record high levels for the time of year for some time in 2023, as illustrated by the image below, adapted from Climate Reanalyzer. On August 25, 2023, the world temperature was 16.99°C, 0.94°C higher than it was on that day in 1979-2000. Extreme heat stress alert High…
The image below, adapted from Climate Reanalyzer, shows that the World Sea Surface Temperature (60°South – 60°North) was at a record high of 21.1°C or 69.98°F for the third day in a row on August 23, 2023. As the image also shows, sea surface temperatures over the past few months have been much higher for…
