The new DOE Climate Report claims that "natural climate signals" like the Pacific Decadal Oscillation (PDO) could have affected global temperatures, but a new study shows that the observed PDO trend since the 1980s is human-caused by greenhouse gas emissions.

Climate models reveal how human activity may be locking the Southwest into permanent drought
The drought has been linked to the Pacific Decadal Oscillation, a natural climate pattern. A new study finds global warming is now influencing that natural phenomenon.

Big new modeling study finds climate change may have locked temperatures in the Pacific Ocean into a pattern could drive drought in the western US for decades. More broadly, this suggests climate models may generally underestimate how much our emissions influence longterm cycles of ocean temps.🧪
Pacific Ocean changes may 'lock in' US megadrought for decades
A major cycle of Pacific Ocean temperatures is shifting due to climate change, and that could drive decades of megadrought in the western US

In July, the Pacific Decadal Oscillation hit its lowest monthly value in **171 years** of data. The current string of negative readings is the longest on record.
How does this related to major research just out on climate change and prolonged SW US drought? 1/4

An unrelenting megadrought has sapped water supplies, ravaged farms and ranches, and fueled wildfires across the American Southwest for about 25 years. Relief might still be decades away, according to new research.
The West’s Megadrought Might Not Let Up for Decades, Study Suggests
Clues from another dry spell 6,000 years ago are helping scientists understand what’s driving the latest one, and why it’s been so unrelenting.
