California students will soon be learning science and critical thinking under the Next Generation Science Standards.
It is unfortunate that Mr. Gary Wechter (see his July 3 commentary “Climate change nonsense”) was not similarly taught. He would then learn the concept of “time scales” and that the climate change associated with the ice ages took place over tens of thousands of years due to Earth’s orbital changes.
He would learn that human activities in the last few decades have increased carbon dioxide levels to those not seen in several million years, and he would understand the basic and well understood physics of the greenhouse effect.
Reading more widely, he might also learn that it is not just “Ms. Harmon and her ilk” who understand the serious impacts that human-induced climate change is having and will continue to have on all of us. It is also several former Republican EPA administrators as well as former Republican Treasury Secretary Henry Paulson who advocate—guess what: a tax on carbon. These prominent leaders also understand that incentives to hasten the conversion to energy sources that are cost-competitive with coal and oil will position the United States in a position of economic strength, not weakness, as the entire world follows our lead.
