Human caused climate change deniers, todays version of the-earth-is-flat people of yesteryear. It is easy for modern technology to show that human activity is releasing the vast majority of the carbon entering the atmosphere and oceans, which is warming the planet. Human activity is releasing the equivalent carbon as 12 Mount Saint Helens explosions every day. How can this NOT affect our climate? The good news is that only one portion of one country (some republicans in the US) deny that humans are causing climate change - the rest of the modern world has listened to the 99% of scientists that believe climate change is human caused and the debate everywhere but 'merica is how to solve the problem, not if it exists.
