But methane’s role in atmospheric chemistry and as a source of stratospheric water vapour means that it has a bigger effect on climate than just the direct effect of its concentration. Before we go any further though, we need to understand that the effective perturbation time for CO 2 and CH 4 in the atmosphere are very different.
