What can we do to stop rising levels of methane?

Recent research shows that levels of Methane gas in the
atmosphere are rising rapidly. It is over 80 times more potent as
a greenhouse gas than carbon dioxide so poses a major threat to
the world’s goal of limiting global warming to 1.5 C. At COP26,
over 100 countries signed a Global Methane Pledge to reduce
man-made emissions by 2030 – experts say cutting methane
emissions is ‘the most powerful lever we have for reducing
warming... over the next 30 years’. So what can be done to stop
the levels rising further? We hear how farmers in Bangladesh,
along with other parts of Asia, are using wetting and drying
techniques in rice paddies to reduce emissions; how cows are
being fed special dietary supplements with a surprising
ingredient: seaweed, but why naturally occurring wetlands are a
cause for concern.
