Trump: 'Nobody Really Knows' If Climate Change Is Real

This statement actually rings pretty true. The feedbacks in the climate are not properly understood. This is why the climate sensitivity estimates for a doubling of Co2 haven't really changed from 3C + or - 1.5C since I think 1992.

Also, this is just one factor. The Earth's climate is incredibly complex. We know that Co2 causes warming but the rest is really up in the air (pardon the pun).

They are slowly narrowing things down the more we learn and the more research is done, but overall Trump is right: nobody really knows to a point where we should be legislating on this stuff.

Wouldn't it make sense to err on the side of caution though? 

If you only had one car for the rest of your life and I said the radiator might be overheating and if it overheats it might destroy the entire car if you don't get it fixed ... what would you do? 

Common sense says get the radiator swapped out or at least looked at and not just keep driving around assuming nothing is probably going to happen. 

Not knowing for certain isn't an excuse for complete inaction given what's at stake. 

Action would be foolish though without a proper understanding of what needs to be done, if anything. Especially any action (such as the UN's solution) which is to take money from all the wealthy countries and give that money without accountability to the leaders of hopelessly corrupt nations.
