Despite all the progress climate scientists have made in understanding the risks we run by loading the atmosphere with CO2, the world is still as addicted to fossil fuels as ever.

By burning fossil fuels, we are already dumping 30 billion tons of CO2 into the atmosphere every year, which has a profound effect on the climate. So, like it or not, we're already messing with a system we don't understand.

The scientists who do climate research understand that much of the ever increasing concentration of CO2 in the atmosphere since 1850 must be attributed to burning those fossil fuels to produce the energy that drives industrialization.

The biggest tab the public picks up for fossil fuels has to do with what economists call 'external costs,' like the health effects of air and water pollution.

We must get rid of fossil fuels by developing injection systems for automobiles, which can run on bio-fuel.

I feel that when we look at what's going on in the world and fossil fuels and all the problems with that - I feel we have to try to move away from that and our best option is wind energy.
