🔥 Methane vs CO2: Global Warming Potential Over Time

Release an equal-mass pulse of methane and CO2 at year zero and watch two live radiative-forcing curves: methane spikes hard then decays over roughly a decade (11.8-year atmospheric lifetime), while CO2 is weaker per ton but persists almost flat for centuries. Drag the time-horizon marker to see the cumulative-warming-area ratio between the two gases shift from about 80x at 20 years down to about 28x at 100 years, showing why the 'GWP' multiplier is not a fixed number.
