Even if we are close to peaking emissions, we must consider the phenomenon of accumulation. Given that CO2 has an effective lifespan of around 100 years and methane about 10 years in the atmosphere, reductions in emissions now will still result in these gases accumulating and impacting the climate for decades to come.
- hollerith 2y agoWhere you have "accumulating", you mean persisting.
- voxelghost 2y agoNo, even if you emit less, you are still 'accumulating', but at a slower rate. And previously released methane is still converting to co2 in the atmosphere, for decades to come.
- hollerith 2y agoOK. It's too late for me to retract my comment, though.
- marcosdumay 2y agoIf you cut all methane emissions right now, the Earth would immediately start to cool down, and do it for a decade or 2. That is half-lives work.
