Sr Bleher says:
“I think that global warming is 100 times worse than what we are told”
Someone please tell me how is that statement in any way objective or quantifiable, especially coming from someone that wants you to believe that he knows what he is talking about?
100X worse rain? 100X higher temperature? More floods? 100X more bacon?
Unsupportable gross exaggerations like this are like steroids for AGW skepticism and only really serves to undermine all the real researchers and scientists who actually work on these questions.
Sr Bleher provides another misleading photo showing a full river “ before the water receded”
I would suggest it was taken at a different time of year/different season, and the 2 photos are 7 years apart in different specific localities.
Massive inundation and massive draining is the norm for this place. Around Manaus the Rio Negro and the Amazon itself normally rise and fall about 20 meters/65 feet each year. You can check this kind of data yourself on google.com
The waters of the Madeira, Purus and Jurua come mostly from Andean snow melt. Just look on a map

While global warming is a good direct candidate for influencing ( rapid melting of) the Andean snows and hence water levels of those rivers fed from that source, Amazon deforestation is not such a direct candidate.
Theses rivers’ massively variable flow volumes are seasonal and always have been.
The trees do play a very important role in the water cycle. They are responsible for transpiration, returning massive amounts of water to the atmosphere. The deforestation is more to blame for the increasingly deeper and longer record floods during the ‘wet’ season.
History shows there was a similar terrible drought in 1915 and several others almost as bad since that time, notably in 2005. But in 1915 deforestation had hardly begun anywhere in the Tropical world compared to subsequent annual totals so it cannot solely be blamed for these droughts. Global warming skeptics love that kind of apparent contradiction, attributing the wrong cause to the wrong effect.
