Professor Myles Allen:

I could calculate it for the Deputy but the point is that for the general discussion one has to think about what would happen if the world did what we are doing. If the world was to reduce methane emissions by 20% it would have a substantial impact. This is why I believe that Ireland could play an outsized role by showing the world how to do it, how to measure it and how to document its success in affecting global temperatures by showing the world how to capture the warming impact of its actions on global temperature.
