As we learned more we removed the outlier scenarios on both ends
The new scenarios have no pathway as optimistic as the lowest emissions scenario from the last round of major climate projections. That scenario—SSP1-1.9—envisaged strong climate action and rapid cuts to emissions, leading to global warming peaking at around 1.5°C.
So basically the latest report says that while we wont hit the worst case scenario we also won’t hit the 1.5°C scenario either and likely end up with between 2-3°C of warming.
Climate change deniers would like to paint this as some great victory. It is better than the worst case scenarios where we do nothing and greatly increase fossil fuel use, but it’s no great cause for celebration.
