1/ Arctic sea ice is a tipping element, right?
'an overwhelming majority of Arctic ice experts say that recent data offer powerful evidence that summer sea ice has passed a point of no return.'

'Tipping point risks are now much higher than earlier estimates, while urgency relates to how fast it takes to act to reduce risk.
Nine active tipping points:
1. Arctic sea ice'

'nonlinear dynamics could generate “tipping points,” or thresholds after which a system changes irreversibly. Polar sea ice is an important example, with positive ice-albedo feedback contributing to the recent decline in Arctic ice.'

'While we do not identify a so-called “tipping point”, the increasing instability is a cause for concern.'

Are you surprised that the IPCC doesn't think it likely that the Arctic will be ice-free in the summer until we're moving to 3°C?
Looking at the observed changes since the the 1970s, it seems fair to suggest there is a major risk between 1°C and 2°C.

The scientific community is struggling to acknowledge the major risk of an ice-free Arctic in the summer in the 2020s, or even the strong possibility of this occuring between 2030 and 2035...
