Do you now believe that human activity is responsible for the climate change we are experiencing ?

Climate is definitely changing and has been for some time. Humans have greatly added to CO2 content in atmosphere over the past fifty years, and significantly polluted the environment. Question really is how much of a factor CO2 buildup will play toward reaching some tipping point in global climate change. And what other factors need to be better understood to forecast future climate. No one has a definitive answer right now. I certainly do not.
