There's this thing in the sky called the Sun. It goes through cycles of solar minimum and solar maximum completing one cycle roughly every 11 years. We are currently experiencing a solar minimum which means there are little to no sunspots on the surface of the Sun facing us. That means less solar wind, or radiation which means less energy to Earth.
Direct effect is that we're experiencing a very minor global "cooling" effect, adversely in 2001-2003 we had a global "warming" effect because of a solar maximum with loads of surface activity and solar wind coming our way.
I'm not saying global warming doesn't exist because it does, it's just immaterial with all things considered and is just being used as a political vehicle for democrats right now. Like someone said before, in the 1970's dem's were screaming a new ice age was coming.
