The sun is it. The sun's magnetic field strength is reflected in the sun spot activity. High sun spots/magnetic field, blocks cosmic rays from the earth. Low sun spots/ magnetic field allow increased cosmic ray bombardment of earth. High cosmic rays make more clouds, cool the earth, less cosmic rays gives clear sky and warming. (Svensmark

The variable gravitational effects of the planets drive the fluctuations of the sun's magnetic activities, see http://www.landscheidt.info/?q=node/262
Humans have no more effect than fleas on the climate. Enjoy the interglacial.
I wouldn't base a weekend on a weatherman, let alone the national economy, or my mental health.
The devil in me is happy to see Americans use Celsius in this latest distraction though.
Just argue how much it may or may not change, as long as it's in metric. 😈
