There is NO global warming, just global climate changes. It changes everywhere based on time of year, sun activity and other exogenous factors. Human activity is NOT the cause of global climate change. The most ridiculous effort made so far to promote Global Warming is the notion that the sun plays no part in global warming. Such a notion is so provably false that it is criminal fraud to propose it. The sun IS the main contributor to global climate changes and the changes cycle according to sun activity which is also assisted by other natural fators like volcanic activity.
