Incredibly, we’re on track to 0.5C above pre-industrial by around 2050

Surprisingly, we’re on track to get down to around 0.5C above pre-industrial global temperature. Within around 30 years.

If you factor in the current, actual (hyper-)adoption rates of green tech. And of course we should, these are mainstream, non-fad roll-outs underway right now by both utilities and consumers.

This is incredible.

Because that represents essentially a trivial amount of global warming.

And nobody is talking about it.

Yes, on the way there, we’ll hit around 1.5C above baseline during the mid-2030s. And a CO2 concentration of around 450ppm, around 170ppm above the pre-industrial baseline.

But the big news is how fast we can ditch around half the extra CO2 after we stop making it.

A global rise by 2C avoided

At the rate of electrification today we’re likely to hit 80–90% carbon neutral by 2042, thus leading to actual temperature and concentration drops in those mid-2030s.

This time forecast is the implication of estimates by ReThinkX and Tesla for calculation of humanity’s energy usage consistent with our current transition rate to renewables.
