I always think that climate scientists and anti-carbon dioxide dumping activists are too one track mind.
While reducing carbon dioxide emission can possibly help to slow down global warming, but that does not help to reduce the carbon dioxide already present in the atmosphere. What these experts fail to address is how to remove carbon dioxide and other greenhouse gases, so that a balance can be achieved to accommodate the inevitable emission, especially caused by uncontrollable forest / bush fires and volcanic eruptions.
When I come across the article that Chinese scientists are having a break through in synthesing starch from carbon dioxide, I know human beings will be saved by their own ingenuity.
As an educator, I always encourage my students to behave like a 4 years old, and then as a 6 years old. A 4 years old child always asks why, while a 6 years old learns by asking how.
