2023 SkS Weekly Climate Change & Global Warming News Roundup #36

Posted on 9 September 2023 by John Hartz

A chronological listing of news and opinion articles posted on the Skeptical Science Facebook Page during the past week: Sun, Sep 3, 2023 thru Sat, Sep 9, 2023.

Story of the Week

Lee adds to a growing trend of intense hurricanes powered by warmer oceans

Hurricane Lee rapidly intensified at a historic pace into a Category 5 storm Thursday night, adding to a spate of extremely intense hurricanes this year and in recent decades which experts say is a symptom of the climate crisis.

Lee is now the eighth Category 5 storm in the North Atlantic since 2016, which means 20% of Category 5 hurricanes on record in the basin have occurred in the last seven years, a CNN analysis of NOAA’s hurricane database shows.

This year alone, Category 5 storms have already appeared in all seven ocean basins where tropical cyclones form, including Hurricane Jova, which also rapidly strengthened into a Category 5 storm earlier this week.

“The increase in Category 4 or 5 storms, especially that we’ve seen over the last couple years due to the increase in rapid intensification, is a telltale sign of climate change, which is exactly what we expect to see in a warmer world,” Kevin Reed, a hurricane expert and professor at Stony Brook University’s school of marine and atmospheric sciences, told CNN.

Comments 1 to 2:

  1. The Guardian had an article about Powis et al 2023.  This paper shows that heat waves hot enough to kill humans will spread to many locations with 2C of warming.  They use a lower wet bulb temperature of 31.5C where previous studies of extreme heat used 35C wet bulb .  Recent studies have found the 31.5C wet bulb temperature is fatal without fans or AC.  

    I have not seen a similar article that discusses when agriculturatal animals like cattle and goats will begin to be killed by heat.  Obviously it will be impossible to air condition pastures.  If the heat cannot be withstood by animals even occasionally, it will be very difficult to keep animals in those areas.  Imagine if they could not raise cattle in Texas for the entire summer!!   At 2C warming large areas of the world are too hot for humans (and presumably agricultural animals) (sorry, I could not copy the diagrams showing where the heat would be too hot for humans)

    Does anyone have a link for the threat of extreme heat to agricultural animals?

  2.  Extreme heat is forcing America’s farmers to go nocturnal

    "Rising temperatures in key agricultural regions across the United States are leading more farmers to harvest in the middle of the night to safeguard the quality of their crops.
    Heat has become a major economic threat to the agriculture industry, and it’s only expected to get worse. By the end of the century, climate change could lead to worldwide crop damage five to 10 times greater than conventional climate models have predicted, according to a 2021 study published in the Journal of the European Economic Association."
