Sure the number jumped, but how much is 15 parts per billion worth?

With Russian built Gas pipelines going in all over Europe? Gas is part of the big transition away from GW emissions. It reminds me of the Montreal Protocol where they successfully eliminated Ozone depleting CFC gases from refrigerants and underarm sprays by replacing them with nasty HFCs.

Another piece of the puzzle. Sulfur hexafluoride (SF6)

There is a huge amount of carbon stored in permafrost. Right now, the Earth's atmosphere contains about 850 gigatons of carbon. (A gigaton is one billion tons—about the weight of one hundred thousand school buses). We estimate that there are about 1,400 gigatons of carbon frozen in permafrost. So the carbon frozen in permafrost is greater than the amount of carbon that is already in the atmosphere today. That doesn't mean that all of the carbon will decay and end up in the atmosphere.
we place total oceanic CH4 emissions between 6–12TgCH4yr−1, narrowing the range adopted by recent atmospheric budgets (5–25TgCH4yr−1) by a factor of three. The global flux is dominated by shallow near-shore environments, where CH4 released from the seafloor can escape to the atmosphere before oxidation. In the open ocean, our models reveal a significant relationship between ∆CH4 and primary production that is consistent with hypothesized pathways of in situ methane production during organic matter cycling.
