I was pleased to read the responses to my prior letter by Steven Dunbar and John Cameron. However, nothing they have written has convinced me that the whole idea of climate change is nothing more than a total hoax. Conversely, there is nothing I can write that is going to change their opinions, and I made a decision not to respond to their comments. However, that changed with the letter by Brad Marchand.

A reference was made to Dr. James Hansen by John Cameron. Dr. Hansen is a former head of NASA, who in 1988 described three possible courses for the world’s climate. One, do nothing and carbon dioxide would accelerate and result in a one Celsius degree increase in the world’s temperature in 30 years; second, that emissions would increase at the same rate as they did in 1988 which would result in a world-temperature increase of seven-tenths of one Celsius degree by now; third, which he believed would not happen, has actually happened: unchanged world temperatures since 2000, except from 2015-16 when the temperature rose slightly after a heavy El Nino and then receded again, even with world carbon emissions increasing moderately.
