Even if we stopped all greenhouse gas emmisions right now, the amount of heat stored in the ocean isn't going to lower any time soon.

To add to this there's also a massive El Nino about to happen and a potentially double Blue Ocean Event.

So with increasingly hot and highly acidic oceans now expelling Co2 (while also dissolving all the vitally important oxygen producing phytoplankton), and fuck all ice cover at the poles to reflect the radiation from the sun, the earth will continue to heat faster and faster.

We're also going to run out of fresh water reserves globally very soon, and arable land is still looking to be 90% depleted by 2050, so massive global famines will kill billions in the next few decades.

And this isn't even taking into account the feriliser shortage and El Nino induced crop die off we're expecting in the next year, which while it might lessen the impact of further greenhouse gasses on our planet by killing a lot of people, is only going to speed up the soil degredation issue we're facing.

Considering our current course of action is basically 'business as usual', the planet might not even be habitable to any life whatsoever once we're done with these feedback loops. 'Venus by Tuesday' is an exaggeration when it comes to timescale, but a very real possibility otherwise.
