A green grid supplying EV’s and home heating is enough to dramatically extend the window of time to deal with the other sources. I am not saying it’s the only issue, just that everything else is largely meaningless in comparison.

Methane gas leaks are front loaded they don’t have long term impact as long as we quickly stop using it. In the short term it’s a problem but long term methane is effectively identical to CO2 because 1 atom of CH4 produces water and 1 atom of CO2.
