Methane Leak from melting ice

Even if we agree 1) that global warming exists and 2) that humans "caused" it, we still have the problem of how do we humans fix it fast enough that will counteract the release of so much methane at once? Is anyone going to be able with authority to tell us that the earth needs to cool by 4 degrees and the only way to do that is to basically kill all humans?

Is someone going to be able to say that the amount of methane emissions here is equivalent to the amount of methane released (and therefore we should cap it) by production of x human widgets? What if this amount of methane is significantly more than what humans produce?

I'm not taking this lightly. I'm not being a denier. I am simply asking: "How do we humans who aren't scientists deal with the information presented here in a proactive manner?"

This article doesn't tell us that this amount of methane is x ppm vs y ppm that humans (or cows?) produce. It does, however, say a specific *type* of carbon production leads to global warming. Good thing. We're hearing that Carbon is bad. We need to stop buying diamonds, procreating, breathing, producing flatulence, driving, and burning anything. We need to start planting more trees and stop building and making stuff. And until everyone basically stops breathing, they can buy carbon offset credits to make them feel better about their polution.
