Methane is the second most important greenhouse gas as it has so far caused about 1/3 of the rise in global temperature. As it is a 28 times stronger greenhouse gas than CO2 and further temperature increases will cause permafrost to melt so that more methane will be released, it is important to control methane levels and reduce methane emissions urgently. This can be achieved by doing more research to understand and find methane sources so that appropriate action can be taken. Also, regulations need to be put in place to prevent methane emissions. Additionally, wetlands need to be protected and farmers need to feed their cattle differently and deal with manure differently so that less methane is emitted into the atmosphere.
