Futurology

We've been geoengineering for some time without knowing it. That geoengineering project has masked atmospheric heating. Now we have to pay the piper

An interesting concept I hadn't considered, that we can take the iodized salt/calcium enriched milk/fluoride toothpaste approach to geoengineering. Put small amounts of something into fuels and it'll get pumped out worldwide without needing infrastructure to support it. Wacky that we were doing that by accident with the sulphur

Also the oceans:

Prof Eliot Jacobson has the decadal increase at 0.32°C/Decade, which given we are at 1.5°C now means ~2.5°C around 2050 and ~4°C by 2100

However, he also thinks the trend isn't linear and is quadratic, meaning an increasing rate of change, so that 4°C could be low
