Do we have sea temperature data from before 1982? Like, thousands of years'?

"The true heavyweights for reconstructing ancient seawater temperatures are the microorganisms. Foraminifera, single-celled organisms roughly the size of the period ending this sentence, occur nearly everywhere in the oceans and have an exquisite fossil record."

Is the frog boiling yet? Can we start doing something about all this now please?

Do what, exactly?

It's December 7, 1941. The Japanese have just attacked Pearl Harbor. Suddenly, most people realize the status quo has changed. The economy needs to make a major transition. Things need to be built at an unprecedented rate. Sacrifices will need to be made at every level because survival is on the line. Victory is possible but it will be a long and difficult fight.

Do we throw up our collective hands and say "it's too hard, the job is too big, not enough people are willing, we surrender"?

Or do we shut up and get to work?

The transition away from a carbon-emitting economy can be done if we have the will, and we will come out of it stronger than ever. We just need to stop saying we can't, and start building.

I'll bite. For start

- stop fossil fuels in transport & energy, minimize plastic production

- stop subsidizing meat & dairy, reform agriculture (pollution, eutrophication, soils)

- reforest / rewild pastures, stop overfishing (carbon capture, biodiversity)

- degrowth & basic income, remove financial drivers of exponential growth (prevent repetition)

ASAP everything, 2050 is too late.

We have reasonably accurate sea surface temperature data from 1945 to present, about 78 years. We have less accurate measurements back to the 1880s. Finally, we have proxy records going back thousands of years, based on isotope fractionation ratios and other paleoclimate data.

This is silly. How can you possibly make such a sweeping statement? How can you possibly believe 7 billion people would feverishly begin working towards something with no sense of plan or intentionally?

Yes, plenty of alternative energy technologies will emit too much carbon during the transition to make them viable. Right now, whenever we build something, we have GHG byproducts all over the place, so we have to really do the math first. A lot of needles will have to be threaded in the coming years if our civilization as we know it is going to survive.

But that doesn't mean we should just give up. And half measures are no longer an option.
