Firestorm of Fake News: “convenient” global hysteria about Amazon based on nothing but twitter pics

Look who’s feeding the fake news?

Global Fire Data shows this year is unequivocally a low fire season in the Amazon. But social media tears and outrage is running at 1000% driven by old photos and fake facts of the Amazon producing “20% of our planet’s oxygen”.

And the media experts reported the house was on fire in the lungs of the world, or something to that effect. They didn’t check the data, didn’t ask hard questions.

Based on hyperbolic twitter pics French leader Macron is threatening to cancel a foreign trade deal. The hype serves the purpose of attacking the right wing Brazilian leader Jair Bolsonaro in the lead up to a G7 summit this week…

Who’s feeding the twitter flames?

@EmmanuelMacron

The photo he used? It’s a stock photo from Loren McIntyre, a photographer who died in 2003.   h/t  @Desesquerdizada

Funding cuts have created plenty of enemies

Amazon River produces monster levels of “pollution”. The dilemma. Should we stop the river?

The mouth of the Amazon is the worst source of “pollution”.

Bad news for fans of The Amazon River. A new study shows that while the Amazon rain forest is the Lungs of The Planet, pulling down gigatonnes of CO2, the river undoes all the good the trees do, and pours all the CO2 back into the sky. Damn that river eh? Lucky it only discharges one fifth of the worlds freshwater.

Apparently most researchers thought bacteria couldn’t digest the tough woody lignin of tree debris fast enough to prevent it getting to the ocean*. Underestimating microbial life seems a common affliction, and we hear was a big surprise that only 5% of the lignin actually ends up reaching the ocean where it might sink to the floor and be sequestered. The rest is broken down by bacteria and released into the air. The clues were there for years that the Amazon was giving off lots more CO2 than people expected, but the consensus was that it “didn’t add up”. So much for that consensus.

Yet another victory for observations over opinions.

Until recently, people believed much of the rain forest’s carbon floated down the Amazon River and ended [...]
