The Atlantic Ocean is cooling at an exponential rate, and nobody is sure why. It's been more than a year of record-high global sea temperatures, including being close to
the collapse of the AMOC. Despite those troubles, though, the Atlantic is now experiencing something quite baffling-temperatures are cooling, and scientists are scrambling to figure out what's going on.
It is the potential of two La Niñas that has scientists so intrigued about what the climate and ocean temperatures will look like for the rest of the year, especially since the record-high temperatures have gone on for so long. There's also a lot of unpredictability here that has left scientists scrambling, too, and while a La Niña in the Atlantic isn't wholly unexpected, scientists don't seem to have been expecting it this year.
And with the Atlantic's cooling rate already speeding up and the Pacific set to start cooling off in the next couple of months, we're likely going to end up with a bit of a "tug of war" between the two oceans as they fight to cool themselves off,
scientists say.
On Tuesday, July 30, 2024, the
Greenland ice sheet posted a remarkable ≈3 Gigaton July gain. Data from the Danish Meteorological Institute (DMI) show this to be one of the highest daily summer additions since records began in 1981. This figure is only bested by the ≈4 Gigaton set at the beginning of the month on July 1, 2024.
On August 14, 2024, temperatures in Antarctica hit extreme lows, with Dome Fuji AWS registering -73.5C (-100.3F) and Vostok dropping to -75.5C (-103.9F). Accompanying the anomalously cold, Antarctic sea ice is up 1.5 million square kilometers compared to the same date last year—
an area more than twice the size of Texas.
There has been no statistically significant increase in the frequency of heatwaves in the U.S. since 1895. There is a slight downward trend.
Much of South America, including Brazil, is grappling with a fierce
cold wave that has meteorologists reaching for the record books.
