A 5th grader here in Massachusetts relayed some information learned from a (unionized government-paid) teacher: Donald Trump is the worst president when it comes to accelerating global warming.
If we do want to worship presidents as modern-day gods on Earth, which president can be considered to have done the most to fight CO2 emissions and global warming?
How about Jimmy Carter? By presiding over a period of recession, he slowed down economic activity in the U.S. and therefore emissions.
Or Richard Nixon, whose “guns and butter” policies generated the inflation that led to the inflation and recession for which Jimmy Carter got blamed. Nixon created the Environmental Protection Agency, whose regulations have led to reduced emissions compared to the 1960s.
Barack Obama? He raised taxes and thereby slowed the economy.
(Separately, is it fair to say that Donald Trump has accelerated global warming? He has been trying to cut back on immigration from poor countries with low per-capita CO2 emissions. Every time someone from a poor country arrives in the U.S., worldwide CO2 emissions should go up. Wikipedia shows that U.S. emissions are roughly 17 tons per person. In Honduras, on the other hand, emissions are only 1 ton per person. Thus, if Donald Trump were to be successful in reducing migration from Honduras to the U.S., CO2 emissions would also be reduced.)
