One Response to Troubling Methane

  1. Steve Case says:

    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.
