When I was in elementary school, I was very interested in science already. I must have been ten or eleven years old. I started experiments with chemistry sets at my home in Mexico. I was able to borrow a bathroom and convert it to a laboratory. My parents supported it. They were pleased. My friends just tolerated it.

The first education to be a good chemist is to do well in high school science courses. Then, you go to college to really become a chemist. You want to take science and math. Those are the main things.

The basic science is very well established; it is well understood that global warming is due to greenhouse gases. What is uncertain is projections about specifics in the next few decades, by how much will the climate change.
