In For All Mankind), fusion reactors are developed around 1986. In the season premier last night hurricane Katrina was just a tropical depression. This is just some basic modeling (literally called "Very Simple Climate Model"). Play around with the input parameters here: https://molab.marimo.io/notebooks/nb_f76e5ZpYmnmpnhd1kwqqJH/app

Even if you turned off CO2 production today, the oceans would keep heating the atmosphere for a long time just because of all the stored heat energy in the oceans (it’s a big ole heat/CO2 buffer). I don’t think your model accounts for that.
That is assuming fusion doesn’t pile out on top of existing past energy source like what happened for all energies.
Here’s another idea: how much CO2 could have been avoided if all OECD had had the gCO2/kWh of France [all along](https://i.imgur.com/sSTpTud.png). We we have been talking about climate change in 1984?
(you can update my [old numbers](https://old.reddit.com/r/TrueReddit/comments/57yuzo/how_fear_of_nuclear_power_is_hurting_the/d8wu97p/))
Large fusion reactors producing electricity means the grid still needs built out to convert fuel based industries to electrical.
This means scaling up the grid a dozen times or more in many places.
Vehicles are another problem, neither road vehicles or ships or aeroplanes can be reasonably powered by electricity (especially in the 80s when batteries were terrible).
This problem only really resolves if you have ‘Mr Fusion’ class devices that work down to the vehicle scale.
