The hottest day on record

There have been numerous temperature records set in recent years.  Apart from record high temperatures for many places around the world, there were 13 consecutive monthly temperature records set for the planet since the previous summer.

According to NASA data, July 22, 2024, was the hottest day on record.  July 21st and 23rd also exceeded the previous daily record, which was set in July last year.  The new record was 17.16 degrees Celsius, or about 63 degrees Fahrenheit.

We are not used to thinking in terms of the global average temperature.  That is the number that keeps climbing and that climate goals seek to keep from getting too high.  The global average temperature is about 59 degrees Fahrenheit.  So, on July 22nd, the Earth was about 4 degrees warmer than usual.  That may not seem like much, but it takes an enormous amount of energy to raise the temperature of the planet by that amount.

The NASA report shows the global daily temperature throughout the year for the years 1980 to 2024.  It clearly shows how much warmer temperatures are now compared with the previous decades.

In many places, people experienced persistent hot weather during the month of July. New York’s Capital Region saw relentless hot and humid weather.  There were 9 days with high temperatures in the 90s.   July in Albany had a monthly mean temperature of 77.3 degrees, which was the highest in any current resident’s lifetime.  This is more than 4 degrees higher than the average over the past 30 years.  The last time the average temperature was over 77 was in 1887.  July was hot.
