Cool roofs: a discouraging technology


I can only suggest that the reader review the Wikipedia article on roof reflectance to see the current low state of public knowledge on anything to do with climate. By that I mean that it seems to me that everyone who enters the arena, whether it be commercial lobbyists, government bureaucracies, academic research institutions, not to speak of politicians, is trying to sell something in a spirit of cynical self interest. This leaves any serious inquirer trying to find some truth needing to study the primary literature on the subject in a spirit of complete scepticism, after the fashion of medical statistician John Ionnidis  who would have us believe that most medical research findings are false. Why even do the research? Ionnidis' view:  it's about careers, grants, publications, and salaries.

Clinton? Trump? Who can you believe in these days? I'm inclined to say no one, except possibly Robert Shiller and Mickey Rourke. Oh yeah, Cormac McCarthy, I believe him. And Winston Churchill, he was certainly right about the Russians. And my friend John, who tells me to invest my small retirement funds in something that pays dividends.


But let's look at a practical example, a "cool roof"outside my condo.


I hate the guy who did this, see the picture above, and his architect and contractor. Sending the worst of their junk heat right back at me. I read in some BS US government publication that cool roofs reflect excess heat "back into the sky." What "scientist" wrote that lie when they know better?


Oh yes, is it true too that cool roofs reduces rainfall by half?

This is what happens when instead of doubling the price of electricity you throw the "solution" to science and free markets. A lot like medical care in the US, eh?
