What Biden has not done: stop issuing drilling permits or impose export restrictions on fossil fuels. The former has some serious limits because of how the courts treat the right to drill as a property right once you hold a drilling lease, and the latter is simply untested.
Let's burn some more fossil fuels!! Whoo hoo,!! I doubt developing countries will stop it as their reasoning is absolutely correct. Developed countries already polluted the environment during the industrial stage and now they are in better position so they shouldn't be the one lecturing about climate change.
Only way to overcome this is by supporting each other financially but as we know human beings are greedy AF so let it burrrrnnnnnn!!
The technological landscape that developing countries have today is very different from what it was a century ago. Wind and solar power are cheap in a way that they weren't then, so there's the possibility of a green industrialization, where they don't have to go down the road the US and Europe and China did.
Everyone is a keyboard warrior, but not all of us have a point - do you?
TL;DR of your citation: Developing nations are a drop in the ocean, fossil fuels have significant downsides, and it wouldn't be fair to put this burden on them - even if it threatens their existence more than most.
None of that disagrees meaningfully with anything I've said. Renewables are a cheaper solution all of us should be using.
The issue is mostly availability and infrastructure. Wind and solar only produce energy when there's wind and solar. However new renewable energy is cheaper to produce but is inconsistent and not as reliable as a coal burning plant.
You can do something like Australia did with their huge Tesla battery to store the renewables but that's not very economically feasible for developing nations, but they should still be building out new renewables for energy and filling the gaps with fossil fuels instead of just sticking with fossil fuels entirely.
