Stop saying human activity causes climate change. The natural forces of climate change are the Sun, oceans and winds.

It is a fact that global temperatures have been stable for 17 years. It is a fact that the natural forces of climate change continue to operate as the building El Nino event proves. It is a fact that the Great Lakes froze to near record levels this past winter and ducks that feed on fish have starved to death due to the amount of ice. It is a fact that no major (category 3 or higher) hurricanes have hit the US since 2005. All are natural developments. CO2 is a greenhouse gas that probably will contribute to some warming of the climate. Since human activity has added 1 molecule of CO2 to every 10,000 of atmosphere, CO2 is not driving climate changes. It, like us, is along for the ride.
