Remember:
🔺Greenhouse gas emissions had to peak and start falling sharply by August 2019 to avoid catastrophe.
🔺Emissions are accelerating.
🔺Feedback loops are beyond our control.
🔺Billions dead by 2050s at 4°C.
🔺Your government knows this.theguardian.com/environment/20…

⚠️ From 2009 ⚠️:
❗"We've always talked about these very severe impacts only affecting future generations, but people alive today could live to see a 4°C rise."
❗"People will say it's an extreme scenario, and it is an extreme scenario, but it's also a plausible scenario."

How soon is now?
⚠️ From Sept 2009: ⚠️
'a 4C rise could come by 2060 or 2070, depending on the feedbacks. Betts said: "It's important to stress it's not a doomsday scenario, we do have time to stop it happening if we cut greenhouse gas emissions soon."'
Do we still have time?

Do we still have time?
From 2009:
"In the 1990s, these scenarios all assumed political will or other phenomena would have brought about the reduction in greenhouse gas emissions by this point. In fact, CO2 emissions from fossil-fuel burning and industrial processes have been accelerating"
And now? 👇

Accelerating towards a death toll of billions:
Global fossil CO₂ emissions? A new record high of 37.1 billion tonnes.
CO₂ emissions likely to increase further in 2019.⚠️

Turning the corner on emissions remains nowhere in sight.

Back to the 2009 article:
🔺A poll of 200 climate experts for the Guardian a decade ago found that most of them expected a temperature rise of 3C-4C by 2099
I wonder how many of those experts would now expect a temperature rise of 3°C as early as 2029?👇

2°C is locked in and looks likely to hit within the next ~15yrs.
3°C is also locked in. I would guess it will hit this century.
4°C is possible by the 2040s. This would be total catastrophe. See recent peer-reviewed science:
