Computer climate models

The cause for the existence and characteristics of the universe some call that God has been and always will be in control of the major events. Mankind is able to influence a relatively minor amount called civilization war peace prosperity health education literature art music etc. But some religions governments and education institutions claim that they can reverse climate change. That means they claim they can make the whole planet warmer when it is too cold and make it cooler when it is too warm. Humans can do that only one building at a time and only using fossil fuels and other high energy density fuels like hydro and nuclear. Claims that mankind is causing climate catastrophe and claims that certain people can reverse this catastrophe are purely Medieval Fairy Tales.
