Thank you, Mr. Bigras.
Please allow me to respond in English.
The climate skeptics, as I like to call them, have been remarkably effective in delaying action on climate change for almost 20 years. The tactic they have used is to emphasize uncertainty. Unfortunately, most of them are not scientists, certainly not climate scientists, and their approach is to attack rather than to resort to research, as other scientists do, and to published papers, papers in peer review journals. It surprises me that newspapers still give these people space on their sheets when the IPCC and many, many other scientific institutions have made it absolutely clear that climate change is real, it's happening now, it's caused by us, and if we don't get off the present track the consequences could be quite damaging.
I trust that provides at least some of the answer to your question.
