Re “E.P.A. Bars 3 of Its Scientists From a Conference to Discuss Climate Change” (news article, Oct. 23):

History may be written by the victors, but thankfully science is not so subjective. However hard Scott Pruitt, the E.P.A. administrator, tries to censor his own scientists, he cannot alter the laws of physics. Nor can he magic away climate change by removing it from his agency’s website.

Nevertheless, it’s clear we can no longer expect the E.P.A. to provide rational answers to our climate problem. The task now falls to Congress, and the logical solution is to ensure that fossil fuel prices accurately reflect their cost to society.

By placing a fee on carbon pollution and returning the revenue to households, we can recoup the economic damages of climate change while weaning ourselves off the fossil fuels that drive it. In passing such legislation, Congress would be on the right side of history, as well as science.

The chemical industry, led by the American Chemistry Council, has led a long effort to improve the public perception of chemistry, for instance via its “Responsible Care” program. There is much to be positive about, as the chemical industry has made tremendous additions to the quality of life.
