Because most scientists have grown weary of responding to writers such as LSU professor emeritus Loren Scott, some who are not scientists, but follow history, pose questions:

Did Scott read the 1992 union of concerned scientists’ declaration titled “Humankind is on a collision course with Earth”?

Does Scott recall that carbon dioxide levels went beyond 400 parts per million in May 2013 for the first time in history, measured with certainty in the Mauna Loa laboratory located on the big island of Hawaii? The same readings were reported this year from New Zealand.

High school chemistry students know carbon dioxide coming into contact with water becomes carbonic acid. Does Scott deny that our ocean is becoming acidic?

Does Scott recall the warning a century ago by Swedish founder of physical chemistry Svante August Arrhenius (1859-1927) that limitless burning of fossil fuels will create environmental problems for Earth?

Students learn from wise professors that half of our oxygen on Earth comes from ocean plankton, now threatened, along with coral reefs, by a warming, acidic ocean.

Submarines generate their own oxygen. When crew members become agitated, the officer in charge orders a release of more oxygen to protect everyone.

Does Scott deny the oxygen supply to Earth is declining because of deforestation and the great plankton die-off?

Has Scott heard the Chinese proverb, “Knowledge is not wisdom”?
