The Cost of inaction on emissions from coal etc.
+Short term impacts
+Long term Impacts
According the the Trump press release, Trump has determined that the Paris emissions deal was bad for the US economy,
This is a good opportunity to point out that it may well be good for the US economy if they stay in as the jobs created by investments in electric cars etc is massive ,
Trump is also overlooking the fact that climate change denial is not part of the equation because... it would make the leader of the richest nation on earth a fruit loop.
Clearly pulling out of the emissions deal would be even worse for the US economy as the long term effects of rapid and almost unstoppable global warming of the planet make the cost of staying in the Paris climate deal minuscule in comparison.
