The Paris Agreement set a target of no more than 2°C global warming above pre-industrial temperatures, but also an aspirational target of no more than 1.5°C.
That’s because many participating countries – especially island nations particularly vulnerable to sea level rise – felt that even 2°C global warming is too dangerous.
But there hadn’t been a lot of research into the climate impacts at 1.5°C vs. 2°C, and so the UN asked the IPCC to publish a special report summarizing what it would take to achieve the 1.5°C limit and what the consequences would be missing of it.
