New research suggests that global warming could cause temperature swings to get unusually extreme. And the regions where the biggest swings will occur are among the poorest in the world — and the least responsible for the greenhouse gas emissions that cause global warming.
Climate scientists already know that as the planet warms, there's a bigger chance of extreme weather: bigger hurricanes, for example, or heavier rainfall.
But a temperature roller coaster could be on the way as well, according to the study, which appears in the journal Science Advances.
Sebastian Bathiany at Wankeningen University in the Netherlands says his calculations indicate that variations in temperature will increase - the normal swings between high and low temperatures will get wider. The variations aren't apparent yet but will be in coming decades, Bathiany says.
This won't happen everywhere, because different conditions affect temperature in different parts of the world. In the tropics, soil moisture plays a big role in moderating or "buffering" temperature swings, according to Bathiany. It's kind of like the so-called Goldilocks effect — moisture keeps temperatures somewhere in between very hot and very cold.
But a warming atmosphere dries out the soil. "And when you have drier conditions," says Bathiany, "then the temperature fluctuations are not buffered as much any more, so you have larger temperature variability."
Bathiany says if the planet continues to warm, temperature variability will be especially pronounced in the Amazon Basin and parts of Africa and Southeast Asia — wet places where a warming climate is drying things out.
Many countries in these regions "are not only poorer to deal with the impacts," he says, "but also in this case the impacts will be worse" than in other parts of the world.
Worse because temperature variation in places like Europe and the U.S. isn't expected to change much. Variation in northern latitudes isn't dependent so much on soil moisture but on atmospheric weather patterns. In fact, temperature variability may actually decrease in those regions and in the Arctic — but with a notable exception: Summertime in the U.S. could see more temperature extremes.
Extremes, in fact, seem to be part of what a warmer world will bring. Another new study found that California will see more extreme wet and dry periods this century. They're calling that the "whiplash" effect of global warming.
Poor women and children hurt first.
“The variations aren’t apparent yet but will be in coming decades”
DECADES????? from now? They can’t accurately predict tomorrow’s local weather. LITERALLY!
Cliche? Sure, but true.
It would be great to see Trump organize a public debate on Global Warming and make sure that ALL relevant data is allowed and peer-reviewed. Drain this section of the swamp once and for all. If Mann wants to submit his findings but not his calculations, he can pound sand.
35 Monday morning in southern MD, high 80’s Wednesday afternoon.. going back to the low 70’s for the highs by Saturday. Is it global warming or is it HAARP?... hmmmm. lets make the left giddy.. Its Trumps fault! He’s screwing the little guy....
I’ve noticed a new tactic. Blame climate change for “the crazy weather we are having”. So now when the global warming crap doesn’t hold because, well it’s cold, they can say climate change is causing that too.
Global Warming? But I was told on May 1 we had the 3rd coldest April on record here in Ohio.
Yeah, its all big yucks until the politicians join in the game. “They’ll put yer eye out, kid!”
So true. Put a school like Harvard or MIT by the scientist’s name and watch the research grants and instant credibility one gets in this “field” of scientific inquiry!
Global Warming/Cooling. Oh no!!
Also, the sky is falling.
“Could be” ... or not.
It might get hotter, or colder, or wetter, or dryer, or windier, or calmer.
And it's all your fault.
“This won’t happen everywhere, because different conditions affect temperature in different parts of the world.”
I seem to remember them telling us these regional variations are just weather. I’m so confused.
They must be seeing the same cooling real scientist are seeing so it’s time to once again revamp the story line to fit the agenda. I think this is number four or five in the last 10 years.
And yet, when the weather is normal, and we point that out, they sniff, "You don't know the difference between weather and climate." It's like witchcraft: it's to blame for whatever you want it to be.
Climate scientists already know that as the planet warms, there’s a bigger chance of extreme weather: bigger hurricanes, for example, or heavier rainfall.
This is a false statement. The assertion is hotly disputed.
Many reputable scientists say there is *no* evidence of more extreme climate events.
This is simply false.
It began....”research suggests”...
Well prove it and then we’ll talk............good grief they are relentless and desperate to get the revenues by charging carbon taxes!...........and this so they can force western nations to accept population relocations of 3rd world countries.
New research suggests that global warming could cause...
Also, WHAT global warming?
“A Temperature Roller Coaster”
WTF! That is the norm for Michigan weather. They ought to spend a few years in the SE part of the Lower Peninsula before they start talking about temperature roller coasters as though it’s something new.
NPR is for people who are mentally still in the 9th grade, but think they are smart.
Global warming is a hoax. Al Gore made $100M in 8 years after he got of office. The UN wants to use the hoax to gain power over the world energy sector, raise money with energy taxes and gain great power worldwide.
