And sensible people will notice that, even drawn like that, it's only
a ~0.6 deg increase across ~30 years. Hardly statistically
significant, given that weather patterns have been known to follow
cycles at least that long. But that's nothing to do with drawing lines
through points, and more to do with how much data you collect before
you announce a conclusion, and how easily a graph can prove any point
you like.

Statistical analysis is a huge science. So is lying. And I'm not sure
most people can pick one from the other.
