Swedish expert says CO2 is not the main cause of global warming

Swedish climate expert Dr. Fred Goldberg has said that carbon dioxide is not the main cause of the global warming. The climate change is not affected by human action, but mainly by the solar activities and ocean currents such as PDO (Pacific Decadal oscillations). He even predicts that the earth is going to experience colder winters in the following years or even decades.
