"If global warming continues, we can expect global temperatures to increase by 1 to 6 degrees centigrade in the next 100 years, causing global sea levels to rise by more than 20 feet. Heat waves, droughts and wildfires will be more frequent and more intense. The Arctic Ocean could be ice free and more than a million species could be driven to extinction in the next 50 years."
