<!-- DRAFT: PFCs (CF4 and C2F6) have an even higher potency if looking at the ultra-long term (hundreds of thousands of years). If we emit too many PFCs,{{qn}} it might become impossible to maintain normal atmospheric temperatures without somehow removing so much CO2 from the atmosphere that plants can't grow (which would be bad, for obvious reasons). --> | <!-- DRAFT: PFCs (CF4 and C2F6) have an even higher potency if looking at the ultra-long term (hundreds of thousands of years).

<!-- TALK: ultra-longtermist perspective: | |||
We shouid define GWP<sub>longterm</sub> as: relative_potency * half_life / half_life_of_CO2 | |||
This would matter for the "immortal" fluoride compounds in thousands of years from now, if humanity never finds a way to scrub them faster from the atmosphere. | |||
