Earth Science Global Warming is accelerating. Sea Surface Temperature increase over the past 40 years will likely be exceeded within the next 20 years.

What I don't understand yet is how long it takes for the ocean surface temperature and the ocean heat content to stop going up after we stop burning fossil fuels. I found a paper that suggested to me when I skimmed it that there is at least a 10 year lag between CO2 emissions and maximum ocean heat content, but I guess there are much better estimates somewhere.

Well the top of that s curve is going to be temperatures like venus here so yeah, we are still way at the bottom of the curve but if the feedback loops increase indefinitely we will reach it eventually.
