Warming
* Ecosystems severely damaged at +1C
* Abrupt extinction events from +1.25C
* Planet's liveability at risk by +1.5C
* Global crop failure fears +1.75C
* Impacts we can't adapt to +2C
* Hothouse Earth zone? +2.25C
* Survival is hard before +2.5C
+2.5C likely by 2050-2075
Ocean extinctions:
'The first completely global bleaching event was in 1998. That was a wake-up call for people here in Australia, because that was the first time ever that the Great Barrier Reef had bleached.'
99% of tropical corals will be doomed at
Many already endangered species are now at risk of suddenly becoming extinct as extreme events
'going past 1.5C is dicing with the planet's liveability. And the 1.5C temperature "guard rail" could be exceeded in just 12 years, in 2030.'
Or even in the
'Even if warming was limited to 1.5 K, all major producing countries would still face notable warming-induced yield reduction.'
1.5C looks like it could deliver major crises. Risks to crops appear set to grow immensely from
