Climate sensitivity = when C02 doubles, what the temperature will be.Most likely 4° C.We will hit 2X C02 by 2050, but maybe not 4° C by then.
Peter Wadhams says we are already locked in to 2° C, it’s just the time lag from lock-in to realization is uncertain.
All greenhouse gases together = 500 ppm C02.
Many say we will hit 2° C by 2030.
Bitcoin will burn the planet, but how fast? – Wired
Bitcoin = 17.0 Megajoules/dollar, Copper = 4.0 Megajoules/dollar
Copper ore grades = 0.5% = more energy waste and more going forward.
Bitcoin alone could push global warming above 2°C in 15 years
From *Nature Climate Change*, which is not too prone to bullshit.
Uncounted fracking emissions means 2°C by 2030
Frack emissions = 4X higher than reported.
Air conditioning will consume 100% of renewable energy by 2050.
If you can live without AC now, you won’t in the future.
Economics + Population + Energy = 2° C by 2030
2018 – 2050 = 6X more energy/person
1950 – 2018 = 2X more energy/person
Still doubtful? Don’t be, the climate doesn’t operate in a political or ecological vacuum. There are too many inputs of everything to predict anything. The only thing we do know is that the hottest climate models are the most accurate.
From 1950 to now energy doubled.
From now to 2050 energy will quadruple.
This is because we will use more energy just to tread water.
In 1950, you didn’t need an air conditioner like you do now.
In 1950, if you needed oil or gas you just stuck a hole in the ground, you didn’t need to blast the shit out of it.
In 1950, you could find copper nuggets as big as your fist, now 0.05% of all the rock we dig.
