For anyone interested in what 1.5C represents, I can't recommend enough the Climate Fresk [1] exercise. It's not just the droughts and floods, the heatwaves, the changes in birds, insects, crop yields, … Include permafrost melting and releasing greenhouse gasses, civil unrest in populated areas that won't be livable anymore, unstable food production, and quite a few other causes and consequences. It's a feedback loop…
Overstating impact is detrimental to the cause. > decimated 1.5C will be bad, but it won’t directly kill 800+ million people in a short timeframe. People simply don’t respond to harm spread across 100 years the way they react to harm concentrated into a few large events.
This take is seriously dangerous.
"1.5C is not so bad, chill people"
When the fact is - we don't know the impact - if we go beyond 1.5.
What we do know (because it's already very much measurable) is that much of the worlds glaciers will melt, causing drought.
What we do know is that eventually the sea levels will rise and drown many extremely valuable coastal areas.
