Apparently there was a drought in the Amazon in 2023 which the World Weather Ambulance Chasers naturally blamed on climate change because such things obviously never used to happen. And apparently climate change causes droughts even though the Amazon experienced record floods in 2012 and 2021 and such things too are blamed on climate change. But of course none of this variability in weather is new. With a h/t to Ryan Maue we learned of a 2023 study by two climate scientists who reconstructed the precipitation history of the Amazon from 1790 to 2016 by combining tree-ring data with an exhaustive search through online archives of historical Brazilian news records. The reconstructed record shows that the Amazon regularly cycles between floods and droughts, that the worst drought on record was in 1865 (followed by an extended severe drought in 1875-1877) and exceptional floods were common in the 1800s, especially in 1818 and 1892.
The wet season rainfall reconstruction looks like this:
The authors found that an approximately 35-year cycle fits remarkably well on the data, meaning the climate system cycles back and forth on its own without greenhouse gases driving the process. The horizontal lines over the first 110 years of the graph show the cutoffs for wet and dry extremes. 1818 was exceptionally wet while 1865 was exceptionally dry. But there were regular episodes of extreme flooding or drought, and the authors quote from contemporary news reports that confirm the pattern they found in the tree ring records.
Of course the World Weather Accusation crowd pay no attention to these things, which is why we predict that within a few years there will be a great flood in the Amazon and they’ll rush out a press release saying you’re to blame for that too.
All of this accurate data is being used to encourage climate change deniers...shame on you. BTW my Brother in Law called me a climate denier
when I pointed out that New Orleans was flooded because Democrat politicians stole all of the money that was supposed to be used to maintain le levies around New Orleans. Shame on me too! That's it #MeToo....or is that taken?
Again,I'm amazed how cyclical(and natural and normal) these climate cycles really are!And like Florida(or California with earthquakes),if you live in these places,you sorta know that these events happen on a fairly regular basis.Though not necessarily on a predictable basis,particularly with earthquakes(which have nothing to do with your SUV or gas furnace.)
