I found this interesting, as it introduces human perspective into climate change. I only suggest that you watch between the preset at 25:43 (not my choice but the one given to me by YouTube) to 28:00 or so, and take note of the following:
- Christopher Essex is a Professor of Applied Mathematics at the University of Western Ontario, Canada. Googling him, I found on the front page only two sources on him, the Desmog Blog, which is used to defame and discredit any who are skeptical of climate change, and SourceWatch, a little more honest in its treatment.
- The graph he points to is one that uses what he calls “spaghetti” to chart the various climate models used by the Intergovernmental Panel on Climate Change, and two solid lines lower down that track actual temperatures. Public policy these days is based on models, and not reality.
- The “15 degree trick” he refers to is merely a standard used by scientists who work in fields like this, that if they are measuring deviations from a norm, they need a norm, and so have arbitrarily decided on 15 degrees Celsius as that standard. Why he refers to it as a “trick” I do not know.
- 40 degrees Celsius is 104 degrees Fahrenheit, and -25 Celsius is -13 degrees Fahrenheit.
- The video is from 2017 and was done in England, as I understand.
The whole lecture is about 38 minutes, if anyone is interested. I like his speaking style and argumentation tactic of placing the whole of climate change in a “human scale”, which demonstrates graphically that in reality, nothing is going on.
