Climate Change alarmists are nut jobs.

Gravitational pressure pulls Hydrogen gas into a single point in space. The enormous pressure causes the hydrogen atoms to bond together into the formation of Helium. The fusion then creates an explosion of energy. The heat from that energy spews out and hits Earth creating the temperature on the planet.

There has always been changes in the amount of heat radiating onto the planet and to blame it on a political candidate or an economic idealogy is pure madness.
