She said that this initiative was about reducing Carbon Pollution, because she believes that CO2, a molecule that is 2/3 oxygen, is causing climate change. Well fair enough, a lot of people believe that. Atmospheric CO2 has passed 400 parts per million, and they proved a long time ago that CO2 traps heat, ( in a bottle, with no outlet) So, as a fraction, 400 ppm is 1 molecule out of 2,500 air molecules. But that's because of humanity right? Humans account for only 4% of the CO2 that naturally enter the atmosphere. Hint. everything that exhales or decomposes releases Carbon, as well as volcanoes and oceans. So,4% of 400 ppm solves to 1/62,500 air molecules from humans. So, her carbon tax, and all other "green" initiatives  will only shave a fraction of that one molecule in 62,500. Will that help the weather? And even if it did, what is the target weather? What we had during the Little Ice age? I wonder if she knows that she is exhaling 40,000 ppm CO2. - we are carbon based life forms :)
