I come to this debate with a consulting engineering approach, giving credence only to facts. I missed the earlier letters, but the letter from Mr. Peate on July 19 caught my attention. He clearly feels strongly about this subject, but knows very little about it. For example, he writes that there is no institutional dissent. Not so. 31,000 scientists have signed a petition that humans are not causing global warming (http://www.petitionproject.org/). Another 1,000 plus scientists signed another report (http://rightwingnews.com/climate-change/blockbuster-new-report-1000-scientists-agree-there-is-no-man-caused-global-warming/). Some of the supporting work has been found to be “spun”. Remember East Anglia, and the exaggerations of Gore and Suzuki. Engineers have to deal with facts only. Take Burt Rutan, the engineer who designed the first plane to fly non-stop around the world (without refueling). In his study ( Google burt rutan climate change), he draws upon real data to show how the current scare is wrong, and that CO2 is not dangerous, but necessary for life. A gealogist, Don J. Easterbrook of Western Washington University, provides a detailed account of the past and present factors, including melting glaciers, atmospheric CO2, past global climate changes, the pacific decadal and atlantic multidecadal oscillations, solar variability and the IPCC predictions. He concludes that global warming actually ended in 1998!
Mr. Peate warns that rising seas may flood parts of the world. Bigger changes than that happen to the globe. I found recently that Australia used to be part of Antarctica, but is moving north towards Asia. Global change takes place on a time scale far larger than our brief time, and we are insignificant in comparison.
The Paris Agreement is about money as the IPCC president has admitted. How many of the “scientists” who support global warming are financially dependent on it? How many of them are really scientists?
Finally, a comment on the statement–“the science is settled”. Not so, never will be. The sun is the centre of the universe; natural disasters are caused by angry gods; eggs are bad for you; eggs are good for you; doctors will never operate on the human abdomen; etc.
