All scientists agree that the climate is changing,and most agree that we have contributed to this, the amount of influence we have had is the debatable point, and the alarmists have had a field day with it. Al Gore being the "Superstar" with his predictions, none of which have proved to be correct.
Fossil fuels have improved our lifestyle and comfort immeasurably, let's not throw them out the window, at least not until we have a better and cost-effective replacement, and after 30 years of experience it seems to me nuclear is the best and safest answer.
Regarding the CO2 debate, we know that CO2 is necessary for life on earth, and that the planet was healthier when CO2 was 10 times what it is now, so why are we not advocating the production of more CO2 - answer, because the driving force behind the global warming debate is not science.
