Proof that man made global warming is a farce? Oh sure.... how about the scientist who invented the term recanting his prior studies and amending them to include ocean currents... oops.... his bad ... when he did... poof ... global warming disappeared from his data.
We are in a cooling trend that will last about another two decades. The drop in temp has already more than compensated what Al Gore said we have caused with carbon.
One more problem.... there is no correlation with carbon levels and global mean temperature. It's the sun and the oceans which dictate the global climate .. not man.
