Most troubling of all: Some scientists suggest the Amazon may already be nearing a tipping point. The region has been so degraded that even a small uptick in deforestation could send the forest hurtling toward a transition to something resembling a woodland savanna, according to an analysis earlier this year by two top scientists. In addition to forever destroying huge sections of the world's largest rainforest, that shift would release tremendous quantities of planet-warming greenhouse gases, which could hasten the decline of whatever forest remained.
"We are already in a very critical situation in terms of climate change," says Adriane Esquivel-Muelbert, a native Brazilian who studies tropical forests at the University of Leeds in the United Kingdom. She's the lead author on a study published this month showing that the mix of tree species across the forest is already shifting in response to rising temperatures.
"If we mess up with the Amazon, carbon dioxide emissions will increase so massively that everyone will suffer," she adds.
By some accounts, it could happen quite fast.
Instead of sucking CO2 from the sky, a deforested Amazon could instead begin releasing stored greenhouse gases. If 60 percent of the forest were to degrade to a savanna, Nobre says, that could unleash the equivalent of five or six years’ worth of global fossil-fuel emissions.
Michael Mann, a climate scientist and director of the Earth System Science Center at Pennsylvania State University, called it "another aggravating climate feedback" loop, where drying rainforest leads to less absorption of CO2, which in turn promotes more climate change, drying more forest.
"We depend quite a bit on the continued functioning of key carbon sinks," he says. "That’s just one of the many things that makes climate change a global problem."
Apparently that new Brazilian president wants to deforest the Amazon. He needs to be shot.
Friendly reminder that the biggest cause of Amazon deforestation is cattle ranching and feedstock production.
I was listening to a right wing podcast and a caller was pretty optimistic about him, even saying he's better than what we have with here in the US.
Now that's some fucking worrying shit right there
You all can rest assured that Bolsonaro will do his damndest to accelerate this process as much as possible. He's a puppet of Brazil's rural oligarchy, and they will not rest until the last human being alive suffocates in the trash heap of a planet we'll leave behind.
Then that rural oligarchy will have made a grave mistake, when they're publicly tortured and executed along with all the other rich and powerful after civilization goes poof.
that's very naive of you considering how much resources the rich have put in to doomsday prepping
There's going to be billions of the have-nots and a few tens of thousands of the haves. After the end there's still going to be a lot of mining and construction equipment laying around, explosives and military
arsenals too.
And the few that are hungry and want to feed THEIR families will sign up to work FOR these people to ensure the survival of their loved ones. There is no “escape clause”, desperate people will do anything to feed their children.
Then I hope those rich cunts are fucking happy their going to inherit a barren rock that doesn't give a shit about how much money they have.
Holy shit wow, does amazon.com have that much money they can just buy forests?
@Sam @Ragekipz hey you seem really vested in this guy, what's your thoughts on this?
In other news the biologist Ismael Nobre (the guy who is taking care of the environment until a ministry is appointed) says that they are aiming to make amazon more valuable than soy and cattle. Which already is, I guess. They're aiming for a middle ground between preservation and exploration.
I think they should crack down on illegal deforestation.
If they're untouchable then I hope they get fucking depressed or something.
Fucking, there isn't even a POINT to cutting down the rainforest. The original reason they did it was to create more farm spaces but the farms can't even get their food to the table because the food spoils because of Brazil's shit infrastructure.
Cutting down forests to own the LIBS
Just fucking kill everyone and everything, including yourself. That'll show those damn LIBCUCKS for wanting their species to not go extinct. Ha!
Match-heads in a flaming box ignite just like the one held in hand.
