Gore- he was wrong and over-hyped the issue. It got people to pay attention at the expense of the rising tide of anti-science Republicans who could look in the mirror and lie to themselves every day about most any issue.
Gore blew it (as did the Nobel people by honoring his over-blown predictions).
The expense of that was the actual issue: The freaking ocean, which everyone ignores, including the OP. The ocean is the real issue.
Note the headline on this report from 2014. It is warmest year on land and Sea Surface temperature combined...

So, for those blabbering about the temperature outside, that isn't half the equation.
Gore was dumb and you people are dumber.
