The Pace Of Climate Change Is Accelerating. Will El Nino Make Things Worse?

The pace of climate change on Earth has quickened in
recent years. Will the faster pace get even faster, or
will things revert back to a more manageable pace.
That will have a lot of repercussions as how
we deal with a hotter planet.

 Now that it looks more likely an El Nino will set in later this year, scientists are debating how hot it will get. 

The three most recent years have been by far the world's hottest on record. El Ninos tend to make the world even hotter.

That's not good news. 

Since we're starting from such an already overheated position, will a new El Nino put ups on a  dangerous new trajectory in which the world will heat up at a new, faster pace. 

Or was it a hiccup, and we'll revert to a somewhat more relaxed but still scary increase in global heat?

Both options are bad, but the rapid heat up version is obviously most frightening, as we'd quickly enter a world where heat waves blow far past anything previously recorded and storms would make Hurricane Melissa look like a refreshing tropical shower. 

In the past decade or two, the past of global heating has accelerated. Which makes people wonder it were at the start of an era when things really spiral out of control.

WHERE WE ARE

A Washington Post analysis found that although the Earth has been warming for a century or more by now, the fastest rate of warming has been over the past 30 years. 

Per WaPo

"For about 40 years -- from 1970 to 2010 - global warming proceeded at a fairly steady rate. As humans continued to pump massive amounts of greenhouse gas into the atmosphere, the world warmed about 0.19 degrees Celsius per decade or around 0.34 degrees Fahrenheit. 

Then, that rate began to shift. The warming rate ticked up a notch. Temperatures over the past decade increased buy close to 0.27 degrees  C per decade - about a 42 percent increase." 

In matters of climate, a decade is a really short period. So this new intense rate of warming might be a big deal. Or it could be a blip caused by factors other than fossil fuel emissions.

Ominously, a number of climate scientists are leaning toward the idea that this is a real acceleration that will last, especially since it's been so robust.

 "There is a greater acceptance now that there is a detectable acceleration of warming," said climate scientist Zeke Hausfather.  

Many people in the eastern half of the United States can be forgiven if they think climate change is sputtering, since it's been so cold there. 

However overall, January was the world's fifth hottest on record. (I'll have more details on January in a separate post). 

While the eastern U.S. froze many other parts or the world were ablaze with unseasonable heat. Much of the western third of the United States has had a record warm winter. Nuuk, Greenland ran an incredible 20 degrees warmer than normal during January. And are plenty of other examples. '

In other words, the recent cold weather was just a temporary fluke. 

EL NINO URGENCY

This idea that climate change might be accelerating isn't all that new. The buzz began in earnest when 2024 became the hottest year on record. This, after 2023 absolutely obliterated 2016 as the previous worldwide record for hot year.

But as we went through 2025, a La Nina pattern that usually cools the Earth barely moved the needle downward. Last year was the third warmest on record, barely behind he previous two years. Now that La Nina is fading, we're starting at that high base line for when El Nino roasts the planet toward more records,.

The cooler La Nina was fading fast this month. NOAA's Climate Prediction Center last week said we'd go into neutral conditions soon (neither La Nina or El Nino). El Nino would probable wait until autumn to arrive. 

 Since El Nino is starting later this year, climatologists are beginning to make 2026 seems unlikely to become the hottest year.  

The UK Met Office is predicting 2026 will end up as second warmest, behind 2024. Which means it will be slightly warmer than the hot years of 2023 and 2024

Hausfather thinks 2026 will be among the top four hottest on record.

 The year to watch is 2027 when, if trends continue, the unprecedented global heat could turn especially intolerable.

WHY IS THIS HAPPENING?

So why didn't the La Nina we just experienced over the past year or so fail to cool the world down noticeably?

One explanation for the added warming is pollution controls. We've seen news on this before, too. Asian nations, and the shipping industry have cut back on sulfur pollutions. Those environmental laws have removed particles called sulfate aerosols from the atmosphere. 

That allows the sun to shine stronger and brighter, heating the world even more.  

However, as WaPo explains, the missing sulfate aerosols in the atmosphere doesn't  explain all the recent warming.  Neither does natural variability.

Scientists, said they've notice low-lying cloud cover has decreased. Those clouds reflect sunlight. Fewer clouds mean more heat. 

One question is why are the clouds disappearing?  Clouds tend to form around particles. A lack of sulfate in the atmosphere might mean fewer particles for clouds to develop. This could create a feedback loop. Fewer clouds mean more heating. That additional heat makes still fewer clouds form, and it all feeds on itself from there.  

The Washington Post explains the question

"If most of the current record warmth is due to changing amounts of aerosol pollution, the acceleration would stop once aerosol pollutants reach zero - and the planet would return to its previous, slower rate.

But if it's due to a cloud feedback loop, the acceleration is likely to continue - and bring with it worsening heat waves, storms and droughts. 'If there is a strengthening cloud feedback - a positive cloud feedback associated with warming - that's going to persist,' Hausfather said."

The  bottom line is, we're playing with fire. The faster climate change moves, the harder it will be to adapt to it, and the more damage and suffering we'll encounter. 

This should be a sign we ought to double down on reducing fossil fuel emissions, and quickly. Humankind has barely been able to manage the changing climate so far. If things go a lot faster than they are now, god help us.
