The American West’s megadrought deepened so much last year that it is now the driest in at least 1,200 years and is a worst-case climate change scenario playing out live, a new study finds.
A dramatic drying in 2021 — about as dry as 2002 and one of the driest years ever recorded for the region — pushed the 22-year drought past the previous record-holder for megadroughts in the late 1500s and shows no signs of easing in the near future, according to a study Monday in the journal Nature Climate Change.
The study calculated that 42% of this megadrought can be attributed to human-caused climate change.
“Climate change is changing the baseline conditions toward a drier, gradually drier state in the West and that means the worst-case scenario keeps getting worse,” said study lead author Park Williams, a climate hydrologist at UCLA. “This is right in line with what people were thinking of in the 1900s as a worst-case scenario. But today I think we need to be even preparing for conditions in the future that are far worse than this.”
Williams used 29 models to create a hypothetical world with no human-caused warming then compared it to what happened in real life — the scientifically accepted way to check if an extreme weather event is due to climate change.

1200 Years???!!!???
What, did they pick that number out of a hat???
Or perhaps there is a written record of the drought 1200 years ago????
Or perhaps, like everything else the democommunists publish, this is just another made up number, designed to scare the population that have voluntarily chosen to live in a desert?
Yes, dendrochronology is a pretty decent proxy for ancient native American meteorologists. Who may have been making observations, but weren’t good at writing things down.
Uh, it’s AP. Notice that ALL major networks are broadcasting this today, almost as if it’s a coordinated effort.
AP, clown show manned (or woman’d) by journalism majors.
Sure, I get my “science” from them. After all, look at the superb job they did on COVID.
Well, that’s rather interesting since the mountains are loaded with deep snow this winter and nobody was around to keep records 1200 years ago.
But… narrative über alles.
Not 40%. Not 45%.
42% folks. Better listen up - THATS how certain these professionals are.
We have scarce written records in North America before the Europeans got here. All we have for written records here are the past 5 centuries, which includes the Little Ice Age and the Current Warm Period. And the western most part of the U.S. was sparsely populated during the Little Ice Age.
But we have plenty of recorded history in much the rest of the world for the past 3,000 years. And that backs up ClearCase_guy's statement. During the Little Ice Age, Sub-saharan Africa had not just years of droughts, but decades. It was during the Dark Age cooling period that the Huns' rain patterns were unlivable, forcing them to move south into the land of the Gothic tribes, which forced the Goths to move south and takeover what was left of the Roman Empire and keep moving south to force my ancestors, the Anglos out of modern day Germany. It was during the Little Ice Age that many indigenous American tribes fought each over in part to take over each other's land to eek out more food (though there were other motivations too, like revenge wars in the northeast).
“...the worst-case scenario keeps getting worse...”

Well then, I guess it wasn’t the worst-case after all.
Geoengineeringwatch.org is a DANE WIGGINGTON promotion production. Years ago I spent days and days reviewing all his science reports, studies and examples of the wild claims he makes and finally concluded that he subscribes to the tenet that “if you can’t convince them with simple facts, baffle them with a plethora overload of nonsense, disconnected BS.”
The guy has no degree for anything I could find, worked for the power company once (which his pages touted) but one could only include it was as some kind of installer (IMO).
Alex Jones used to tout him regularly on Chem Trails, HAARP and other conspiracy stuff. IMO, he’s a huckster.
Earth’s orbit changes on a reoccurring pattern as does its axis tilt. Both of those caused the Sahara to green then dry out.
Heres the science

They could always try to build some dams and save up water for emergencies like this instead of tearing them out.

Yes, and geologic record (soils analysis).
dendrochronology, when paired with carbon isotopic ratios and oxygen isotopic ratio analysis gives a accurate account of the local humidity levels, rainfall levels and co2 levels. The O16/18 ratios show how much evaporation is coming from ocean water with O16 evaporating more than O18.
The dendrochronology in the desert southwest shows periods where droughts lasted for centuries. The wet period of the 1920 and 30s was far far from the normal for that region all the water compacts are based on outlier data that won’t repeat for centuries more. The long term avg flow of the Colorado river is 7 million acre feet or less per year when you look back over the last three thousand years. This is evident in the sedimentary record along the river channels and its erosional down cutting vs stratagrafic record as well.
And, yes, their are juniper trees more than 2000 years old out west.
Of course, proving that puny little man caused climate change is a whole different matter.
As long as the phrase “climate change” is in the first sentence, we have an award winning article./s
You have to have river flows to dam up. That region has periods lasting centuries where river flows will be half to kne quarter what they were during the dam building era of the 1930s the Colorado river system has more dam capacity that it can possibly fill already it was built for 14 million acre feet per year the multi century avg flow of that river is half that value no amounts of dams will fix that. Desalination will be needed, both ocean water and saline groundwater desal will be needed
Such posing, How about the record snows in Donner Pass this past December? We are fools to even read this nonsense.
Total BS. Colorado is having a very wet winter. Record snowfalls and snowpack.
So how about ditching the 200 billion dollar boondoggle “bullet train” to Fresno and building some desalination plants?
I guess that will solve the rising oceans crisis.
