Well, there was that one really big war in the 1940s...
- jonhohle 3y agoDoesn’t that suggest sea transportation may be a bigger contributor than greenhouse gasses? Industrial production was at its limits during that period, but I would imagine cross ocean cargo was down significantly. It would be interesting to see what pandemic years looked like with thousands of ships sitting for months off shore. Edit: there might be something to that idea - https://arctic.noaa.gov/Report-Card/Report-Card-2022/ArtMID/8054/ArticleID/988/Sea-Surface-Temperature#:~:text=Highlights,observed%20in%20the%20Chukchi%20Sea https://arctic.noaa.gov/Report-Card/Report-Card-2022/ArtMID/.... maybe globalism is the issue. One more edit: container ships are effectively giant heat sinks with a ton (literally tons) of surface area (corrugated containers), sucking heat from the air and dumping it into the ocean. If that hypothesis has merit, I would expect the LA ports to have an increase in temperature during that same period.

- jonhohle 3y agoThat’s definitely possible, but complexity makes errors more likely. According to Google^TM, it takes 20-200 years for CO2 in the air to dissolve in the oceans and yet there are immediate effects during WW2 and COVID.
