Scientists:

1. Great Barrier Reef 'dead' by 2035
2. Amazon Rainforest 'dead' by 2048
3. E. Himilayan glaciers gone: 2035
4. Caribbean corals dead by 2034
5. no Arctic summer sea ice by 2028
6. simultaneous global crop failures and water scarcity crisis from 2029

It's very hard to project, but recent studies suggest 2023 as possible, with the early to mid 2030s likely.

My educated guess: 2026-2028.
Simultaneous catastrophes will certainly have begun to occur around 2C of global warming. The earliest scientific projection for 2C I've seen is 2030, but the risk of simultaneous crop failures will simply increase and increase from now on as we pass 1.5C. https://twitter.com/ClimateBen/status/1226103077163425792?s=19
This thread suggests crop failure catastrophe is entirely possible before 2029. Read to the end: https://twitter.com/ClimateBen/status/1205577540531838977?s=19
4 billion suffer water scarcity today for at least one month of the year and the UN suggests this will become a global issue year round within a decade.

This has been understood for years.
