Suppose we say, "We have a climate emergency going on, there's no way we're going to decarbonize our economies fast enough, to hell with biodiversity, we are going to drain the swamps". What happens then, after implementing such a policy on a global scale? Why is draining wetlands not a good idea, climate-wise? They are responsible for 1/5 of the world's methane emissions, the latest IPCC report says

    $\begingroup$ Swamps are carbon sinks, since plants there rot slowly or not at all, due to the wet conditions. Remove the water, replace it with oxygen, and you get normal decomposition of plants, cue CO2 emissions. $\endgroup$

  • $\begingroup$ Look up CO2 emissions from drained peatlands. They are much higher (per area) than methane emissions from wetlands. $\endgroup$

  • $\begingroup$ @roland do you mean in co2 equivalent? $\endgroup$ Nov 18 '21 at 15:35
