The globe has warmed 1 degree Celsius since the 1970, basically in 45 years the earth has warmed so if we think about a couple of hundred years ahead with the technology enhancements that we’re discovering, and with he population increasing more and more energy will needed to supply those people with power and currently oil prices is low which makes it cheaper to burn oil then switch to cleaner alternative energy such as solar. to get earth to stop at 2 degree Celsius the developed countries need to reduce fossil fuels by at least 80%. But the developed countries are ignorant since climate most affect them like it would other 2nd and 3rd world countries. with the deforestation that’s going on around he world is another huge cause due them releasing large amounts of carbon and because there is no more trees to absorb said carbon it just stays in the atmosphere. the developed countries need to switch to cleaner alternative energy before the damage becomes irreversible.
