   Over the years, the IPCC tells us in all their assessment reports how many times more powerful methane is at trapping heat than CO2. Here’s the list:

   AR# GWP
   AR1 63
   AR2 56
   AR3 62
   AR4 72
   AR5 85
   AR6 82.5

   The Global Warming Potential (GWP) is now 82.5 times more powerful than CO2.

   By 2100 atmospheric methane will probably be at least ~2500 ppb but we are NEVER told how much global warming that will cause. The reason for that is it will be a nearly unmeasurable amount. If anyone says it’s more than 0.1°C they should show their work or provide the source. It’s probably less than 0.05°C.

   The scientific warming potential of methane is 7.2 times that of CO2.
   Here is the proof with a lot of math by a Phd level chemist.
