Looming El Nino Getting More Likely To Become "Super" It Means Ever More Extreme Weather On Climate-Fatigued Planet

Scientists have been telling us for months now that a new El Nino global pattern is about to start. That type of thing tends to warm up the world. Combine an El Nino with climate change, and you can take the global climate to new, hot, heights. 

Now, we're being told this could well turn into a "Super El Nino" and that makes the news even more potentially grim. At least if you're not a fan of punishing droughts, super storms and dangerous, record smashing heat waves.

Yes, that sort of thing is going on already, but a Super El Nino could make things much, much worse.   

Per the Washington Post: 

"During a typical El Nino, a warming patch of water in the equatorial Pacific Ocean influences what regions experience droughts, floods, extreme heat, hurricanes and declining sea ice. During relatively rare super El Nino events, happening once every 10 to 15 years on average, the effects may be stronger, more persistent and more widespread."

The Washington Post reports;

This El Nino "could break the record for El Nino intensity set in December, 20125, when sea temperatures in the central equatorial Pacific reached 2.8 degrees Celsius (5.04 degrees Fahrenheit) above average."

Each El Nino is different, because underlying natural weather patterns can affect it. And climate change makes the effects of El Nino even less certain. The effects of El Nino will probably peak during the upcoming winter. Overall,  some of those effects include:

Drought:

Sone tropical countries, like the Caribbean and Indonesia, could face serious droughts.  So could central and northern India, where a super El Nino can disrupt and even stop the annual monsoon season. Serious droughts have an excellent shot at developing in portions of Central Africa, Australia, the Philippines, Central America and northern Brazil.

The  El Nino could be really bad news for the western United States. Coming off a record warm winter, and unprecedented March heat that has already set the stage of water shortages, the El Nino could create an especially hot, dry summer in the West. 

However, El Ninos can cause unusual humidity in the West. That could lead to some beneficial rains, but also severe storms that would extend into the Plains.  Usually, the worst of the United States severe weather season usually tapers off in June, but this year, it could help extend the season longer, if the El Nino develops fast enough. 

While certain areas of the world would get much drier under a super El Nino, the overall threat of flooding in the world would increase due to higher levels of atmospheric moisture brought on by the el Nion

Storms and Hurricanes

On the bright side, the potential Caribbean and Central African droughts would be related to a suppressed Atlantic hurricane season.  Disturbances coming off the west coast of Africa would be weaker and less frequent, lessening the chances that any of them would develop into hurricanes. 

Much more importantly, El Nino would contribute to strong upper level winds in areas of the tropical Atlantic. Those strong upper winds cut wannabe hurricanes off at the pass, destroying tall thunderstorms before they can organize into a tropical storm.  

The U.S. got a break last year with no landfalling hurricanes. An El Nino could make us lucky for the second year in a row. But that comes with a big caveat. El Ninos tend to reduce the number of hurricanes. But it doesn't eliminate them. It takes only one hurricane to cause a cataclysm. We're not entirely safe. 

There will be enough cataclysms with or without hurricanes anyway. Next winter, if the strong El Nino develops, the South, including Florida, would become cool and stormy, with the risk of wintertime severe storms and tornado outbreaks. 

We'd also see an increase in flooding across Peru and Ecuador, sections of northern and eastern Africa and in the Middle East. 

Heat Waves

Virtually every place on Earth would be at risk for punishing, record heat waves. Africa, parts of the Middle East, Africa, Europe, the southern U.S. and possibly Australia would be most at risk. 

If this super El Nino does in fact get underway, 2027 has an excellent shot of becoming the hottest year on record, even besting the especially torrid 2024, the current record holder. Because of a lag between the development of an El Nino and how it affects global weather patterns, I doubt this year will be the world's warmest. 

Climate change has created a sort of step-up trend in which pretty much every El Nino creates a new record for global warmth. Between El Ninos and during La Ninas, which should cool the Earth, global temperatures tend to just level off.

"Due to the increasing concentration of greenhouse gases, the climate system cannot effectively exhaust the heat released in a major El Nino event before the next El Nino comes along an pushes the baseline upward again," Defense Department meteorologist Eric Webb said in the Washington Post. 

 VERMONT EFFECTS

It's always nearly impossible to tease out what effects an El Nino might have on a pinpoint area like Vermont. But we can give some general thoughts that aren't exactly a forecast, based on what we've seen in past super- El Ninos

The most noticeable effects here are warm winters. During the 2016 super El Nino, Burlington what was its warnest and second warmest winters on record in 2015-16 and 2016-17.  (The warmest winter is now 2023-24)

The 2015 El Nino might have helped contribute to the hottest December readings in Vermont that year, breaking records set December, 1998 during a previous strong El Nino. 

Chances are next winter won't be the kind of long, drawn out, persistently cold affair we endured this year. 

As for storms, it seems that Vermont is at a higher risk of trouble, but no guarantees. It's hard to know whether El Nino had anything to do with it, ut the Great Ice storm of January, 1998 and serious flooding in June and July of that year were doing a super El-Nino.

I also recall some spring floods during the 1982-83 El Nino, mostly along Lake Champlain due to persistent rains and snows in April and May, 1983. 

Although we had some notably wet months during the 2015-16 El Nino in Vermont, there wasn't really much in the way of serious flooding, though there were some local flash floods in the warmer months.
