The developing world is the one suffering from the impacts of global warming. Several countries in Africa are suffering from wars worsened by climate change driven migrations. Countries like India have a mix of cities running out of water, cities flooded by water and cities drowning in pollution which is almost certainly gonna erase years of people's lives eliminating any improvements caused by better medicine.
Cheap oil, or expensive oil, are both bad for developing countries. It's literally not possible to give the hundreds of millions of people in developing countries a better future with fossil fuel driven growth.
All our thinking and planning has to start from that basic fact.
