‘We are perilously close to the point of no return’: climate scientist on Amazon rainforest’s future | Amazon rainforest

1. Didnt they cut down rainforest to have a climate meeting?

   AI say this.

   Yes, deforestation is indeed occurring in the Amazon rainforest to prepare for the COP30 climate summit in Belém, Brazil. A new four-lane highway is being built through previously protected areas, and this has raised concerns about the environmental impact

2. We are all completely and hopelessly doomed.

3. We are close to the point of no return. Unfortunately our view of it is in the rear view mirror.

4. This headline might have applied 15 years ago.  We are long  past there point of no return. 

5. “And I let myself rest in that moment, when it was clear that we would not avert our fate, due to our own inaction.”

6. Read The Ministry for the Future. I had no hope until I read that book – now I see things can change and we can have an incredible future in balance with nature. Unfortunately, I don’t yet see any nation moving in the right direction

7. Cry all we want it’s not going to change, too late. The kind of change that needs to happen so that everyone is able to do better about it would take decades in this world’s pace.

   It’s happening, make peace with it

8. This is why zohrans win is so important. A genuine revolution can turn this around so quick

9. Stop saying that each time. We are already pass no return 

10. Siemens can’t make gas powered turbines fast enough to keep up with demand for data centers.

11. The world’s leaders have seemingly unanimously agreed that keeping a livable biosphere is less important than ensuring the richest people get a little richer.

12. It’s over bro. Plan accordingly.

13. Do we all wait for the point of no return when it won’t matter anyway, or do we strip the people in power of their power and start fixing things before then? Tune in next year to find out… 🙄

14. >Brazil is one of the world’s biggest agricultural exporters. How would a tipping point affect global food security?

    >Almost 50% of the water vapour that comes into the region from the Atlantic through trade winds is exported back out of the Amazon on what we call “flying rivers”. I was the first to calculate the huge volume of these flows: 200,000 cubic metres of water vapour per second. My former PhD student, Prof Marina Hirota, calculated that tropical forests and Indigenous territories account for more than 50% of the rainfall in the Paraná River basin in the far south of Brazil, which is a major food-growing area. These flying rivers also provide water for crops in the Cerrado, Mato Grosso, Mato Grosso do Sul, Goiás, Paraná, Santa Catarina, Rio Grande do Sul, Paraguay, Uruguay, and all that northern Argentina agricultural area. So if we lose the Amazon, we are going to reduce the rainfall there by more than 40%. Then you can forget agricultural production at today’s levels. And that would also contribute to converting portions of the tropical savannah south of the Amazon into semi-arid vegetation.

    LAMF moment.

15. Actually, we have passed it. When the permafrost starts melting (which it is) it releases massive amounts of methane which is on order of magnitude worse than CO2. If we were to stop burning fossil fuels today it would take like 50 years for it to start to reverse. But Drill baby drill, let’s burn some more beautiful coal, stop the wind turbines. We are doomed, just can’t admit it-
