As El Nino Was Brewing, May Was World's Second Hottest On Record

May, 2026 was the world's second hottest on record.
An El Nino has started, which is expected to work 
with climate change to bring global temperatures
 to new and dangerous heights. 

 We're closing in on the end of June, and I realize I never did do my monthly fever check of the world in May 2026. 

As has been the case for years now under the onslaught of climate change, the world continues to run a very high fever.

May, 2026 was the world's second hottest on record, trailing only 2024, the NOAA's National Centers for Environment Information tells us. If you are under the age of 50, you have never seen a May in which the world was even a little cooler than average. 

Climate change has been with us for half a century, and in the past couple of decades, that has gotten more and more obvious.

The warmest places relative to average were much of the Arctic and Antarctica, central Canada and the northwest United States, western Russian, much of southwestern Asia and parts of the North Pacific.

The Pacific Ocean off the west coasts of Mexico and northwestern South American were very warm. That was a sign that El Nino was building. 

Officials declared this month that El Nino is underway. It's forecast to reach record intensity. Since El Ninos tend to warm the climate, a combination of an extreme El Nino and climate change is bad news for the next several months at least. El Nino is expected to peak this winter. 

More intense and longer heat waves, intense droughts and storms are on the horizon for many parts of Earth. Buckle your seat belts, it's going to be a rough ride. 

As usual, you could find a few cooler spots around the world. Those included centra South amerce, northeast Russia, western Australia, Southern Africa, eastern Antarctica and a portion of the North Atlantic south of Greenland. 

That "cold blob" south of Greenland is ominous, too. It's a sign that fresh water from melting glaciers in Greenland is messing with the currents in the Atlantic Ocean. If the warm currents that keep western Europe mild collapse, there could be sudden and extreme changes to the climate in Europe and elsewhere. Nobody is prepared for these changes. 

So yeah, I'm full of good news with this post.

Let's move on to how the United States has been doing. 

UNITED STATES

May, 2026 was warm out West and a little cooler
but not extremely so in the East. 

May was the 28th warmest, or 105 coolest, if you want to look at it that way, says NOAA's National Centers for Environmental Information. 

As had been the case all winter and early spring the west was on the warm side while eastern states were somewhat cooler. Three states - Washington, Oregon and Florida, had one of their top ten Mays on record. 

No state had a particularly cool May. The state that came closest to a chilly May was West Virginia, which had the 39th coolest May out of the past 131 years. Here in Vermont, it was the 51st coolest out of the past 131 years. 

The United States had its  55th driest on record, or 78th wettest May on record NCEI says. Idaho, Minnesota, Wisconsin and Michigan had one of their top ten driest Mays on record. On the other hand, top 10 wettest May honors for 2026 go to Alabama, Georgia, and Louisiana. 

Vermont, as you might remember, was also on the damp side. The Green Mountain State had its 19 wettest May out of the past 131 years. 

It won't be long until we have our June summary to see how the start of El Nino is affecting us and the rest o the world. That report should come out in mid-July.
