It will still be an issue, but it's solved to an extent that it isn't discussed. The solution is pretty much in the economics of nuclear and solar power which become much cheaper than burning coal or oil.
Even if you shut down all coal/oil/gas/biofuel powerplants by the end of the decade, add in a 3rd "new technology" (e.g. fusion) ready in 1 year, find and deploy perfectly efficient battery technologies for rewables, decrease the cost of renewables by 50%, electrify cars and buildings (i.e. move off gas) at the maximum rate while finding huge increases in their efficiences as well all while taxing carbon emissions like crazy...
Global warming still ends up being a problem and the temperature continues to rise. Please don't think "we just need to wait for <x> to be solved in the next 10 years and the problem will go away!", we need <a> through <z> to happen not have enormous climate change impact by 2100.
