The May/June 2018 issue of Engineering Dimensions contains a letter to the editor on page 74 entitled “So much for green science” that seems to deny anthropogenic climate change and suggests the world’s best atmospheric scientists are wrong. Average temperatures are forecast to rise by 3 C to 4 C this century and will cause significant sea level rise, acidification of the ocean, loss of coral reefs and stress on the entire oceanic food chain. Wildfires, hurricanes, heat waves and droughts with crop failures are all more likely. With such important impacts, let’s all pay attention to our best science and try to recognize false or incomplete arguments from non-professionals in climate science.
