Remember:

1. Global crop failures by 2°C.
2. Most humans dead by 4°C.
3. Earth uninhabitable by 6°C.
4. We risk 2°C by 2035.
5. We risk 4°C by 2065.
6. We risk 6°C by 2095.

One tweet is worth a million newspaper front pages.

1. It will never be too late to try to limit the damage/suffering of the expanding ecological-climate catastrophe by challenging media silence, destructlive growth & short-term profit maximization.

We need economic system change action now to avoid 3-4C by 2050-2100.

2. 'Risks of simultaneous crop failure.. increase disproportionately between 1.5 and 2°C'

Over 1.5°C represents 'a threat to global food security'

'Agriculture is already at moderate risk, which becomes high risk around 2 degrees' vox.com/platform/amp/s…

3. Meta-analysis: 70% of studies show declines in crop yields by the 2030s (half indicate 10–50% declines):

We are in the danger zone.

2°C will hit as early as 2034-2038 without stunning emissions cuts towards zero in the 2020s.

4. Scientists still hope to stay below 2.5C but it would take a 'herculean effort' to avoid 4C, at which point 'mass death' would be likely:

And from 2009: 4C by the 2060s if emissions don't peak & plummet by the 2030s:

5. This recent study confirms 3-4°C looks increasingly likely by 2050-2100 as emissions continue to rise, and that >5C by the end of the century is beyond catastrophic for humanity, and entirely possible.

We must change everything to protect everybody.

6. This is tough information to take in. I feel better when I try to take action to support the Climate Justice Movement which has known for decades that capitalism must be transformed and replaced for decent survival. Individual-collective action is possible. Keep going.

7. Just to add, here's a thread full of key info on parts per million of CO2 (ppm) in the atmosphere and 'CO2-e' which includes all greenhouse gases and forcings. The thread has two more sources on 5-6°C being enough to make the planet uninhabitable.

8. Because the statements in the tweet are so extraordinary, I have to concentrate on extensive explanatory details which back them up as convincingly as possible in the thread.

It's also important to suggest actions, so here is a thread of ideas:

9. A video on 6C:

10. Some interesting quotations from high-profile scientists here, and see conversations under the tweet for further debate/discussion.
