Dear all
Although I am aware that methane is a more powerful 'greenhouse gas' than CO2 I had not previously heard of the problem of methane leakage which could have a large role, and cutting emissions by 45% by 2030 would prevent 0.3 C of warming by itself.

In 2021, the last year for which full data is available, methane reached 1,908 parts per billion, 2.6 times higher than before human activity started transforming the atmosphere. Its role in global heating is often overlooked, but human-caused methane emissions are responsible for about a third of the rise in global temperatures seen over the last century. Today, the impact remains large, with the methane in the atmosphere responsible for about 25% of the heat trapped by all greenhouse gases.
Fast action would dramatically slow global heating as methane is short-lived in the atmosphere. An emissions cut of 45% by 2030, which the UN says is possible, would prevent 0.3C of temperature rise. Methane emissions therefore present both a grave threat to humanity, but also a golden opportunity to decisively act on the climate crisis.
