Looks like we’ve taken another step towards the feedback cycle in the destabilisation of our previous climate balance. The BBC is reporting that parts of the ocean are now emitting methane from ruptures in the seabed, which is bad news for a number of reasons:
- Oceans constitute a considerable sink for greenhouse gasses. This will likely use up that spare sink capacity much faster, and speed up the point at which the oceans start to heat up enough to release the carbon they already contain.
- Methane is a much more potent greenhouse gas than CO2, so if it doesn’t get absorbed by the oceans before it reaches the surface, that means we need to be a lot more aggressive in combatting climate change.
- This means that our predictions from the IPCC are even more conservative, and thus more likely to give politicians and businesses an excuse not to do enough.
