The letter in the Aug. 16-22 edition of the San Clemente Times, titled “Man-Made Climate Change is a Farce,” made several valid points. Yes, the climate has been changing throughout the history of the earth and will continue to change. Other aspects of our environment also change.
Ocean tides rise and fall every six hours or so. Geological change occurs over millennia. These are all true. But much of our body of scientific knowledge is not directly observable by the general public. We rely on the research of specialists in scientific fields to add to this body of knowledge, and these specialists build a consensus as to what is fact. We accept the consensus of physicists that matter is built up of atoms. Few people will argue with that, even though it’s not apparent.
Similarly, we must accept the consensus of specialists that human activity makes a significant impact on climate change, and that we can do something to reduce the rate of change. The repository of considerable knowledge concerning the climate is NASA, and quoting from a NASA website, “Multiple studies published in peer-reviewed scientific journals show that 97 percent or more of actively publishing climate scientists agree: Climate-warming trends over the past century are extremely likely due to human activities.” We may not want to accept that as fact, but we must.
