Dangerous Assumptions
1. CO₂ sucking machines will soon work
2. Economic growth isn't destructive
3. Global warming of 2°C won't break us
4. Arctic summer sea ice loss isn't key
5. Permafrost thaw isn't yet a worry
6. Sea level won't rise 0.22m by 2035

We should work on the assumption that CCS, DAC, BECCS won't work soon, though the IPCC suggests they should be up and running well by now.
This means 'net zero 2050' must be rejected and replaced by 'real zero 2025-2030'.

Economic growth is destructive. The economy is causing a mass extinction and the collapse of Earth's major ecosystems. Degrowth looks like the only logical alternative if we want decent survival.

The destruction of summer Arctic sea ice by 2035 give or take 14 years will have global implications, that much is agreed upon by most climate scientists it seems.
How bad will they be?

Sea level rise is already a threat to coastal ecosystems, island nations and some megacities. By the 2030s the disruption will be enormous. Island nations will likely succumb by mid-century. By 2065-2095 most major cities could be wrecked.

A "realistic range" of sea-level rise
With the current global temperature level and rate of temperature increase 'we could get 5 to 10 feet' before 2100.
'impacts would be truly dangerous & destabilizing' even at 3-4 feet.

Antarctica appears to have hit irreversible collapse. How rapidly will it occur?

See the two @PaulHBeckwith videos here for 0.22m by 2035.
Sea level rise and subsidence will severely damage or even begin to wreck major cities from 2035 onwards.
What kind of extreme, exponential sea level rise might we see?
+1.75m by 2056?
