FWIW there is an excellent book on the psychology of climate change denial that I can recommend, if you can deal with the seemingly relentless series of challenges to get people to stop denying and start to act.
Unsurprisingly, everything JP says and does fits into the mould very neatly.
Relearning skills lost to the market economy is to be wholly encouraged, but prepping for absolute self-sufficiency is futile. Hoarding food and water only puts off your day of reckoning, but having some supplies is wise.
Humans have depended on each other since our inception, we evolved to live in small bands/tribes which is why we are unable to avert our course of catastrophe, we are not well adapted to deal with the scale of civilization and it's problems. Myopia is our curse, its why we work best in small groups. Trying to go it alone will also end in failure. Lesson: Get involved with your local community.
I recommend you read Lean Logic; A Dictionary for the Future and How to Survive https://www.amazon.com/Lean-Logic-Dictionary-Future-Survive/dp/1603586482
Or the linear styled sister book if you prefer a front to back reading. https://www.amazon.com/Surviving-Future-Culture-Carnival-Aftermath/dp/1603586466
I can't give you a straight answer but I would suggest reading about how their psychology works to prevent them from believing it. This book was recommended to me by a geographer and climate scientist and it's very good.
Don't Even Think About It: Why Our Brains Are Wired to Ignore Climate Change
Otherwise, google it! :)
Well, it's not meant to be an attack piece, just a bio. You can make your own judgement. There are plenty of people who aren't evil who are climate change deniers. They do it for lots of very powerful reasons. If you want to better understand the situation more generally, I recommend you read
Don't Even Think About It: Why Our Brains Are Wired to Ignore Climate Change
It's honestly a better way to kill time than arguing with deniers online! It helped me understand the psychological and conditioning that has gone into creating a large base of deniers who are very hard to convince. Regular climate change deniers often think they're doing the right thing while the masterminds that have cynically orchestrated the misinformation and propaganda that has screwed things up know well that they're the bad guys.

American Exodus: Climate Change and the Coming Flight for Survival
. What will happen when the United States cannot provide food or fresh water for the overheated, overcrowded cities where 80% of Americans currently live?
In this compelling cautionary tale, Slade argues that we are entering a long period of global desperation which will be characterized by human migration on an unprecedented scale. American Exodus is a frighteningly believable survey of our immediate future

Giles Slade discusses his book American Exodus -- Climate Change and the Coming Flight for Survival.
While I share the outrage, this is a very 1st order assessment of a much more complex phenomenon. Yes, the top layer of deniers are in it for the money etc, but the millions of unpaid shills are not on the whole. If you want a much deeper treatment of this breakdown in human psychology that is behind climate change denial, I strongly recommend reading Don't Even Think About It: Why Our Brains Are Wired to Ignore Climate Change, just not when you're in a dark mood already....
As in many things, the big issues of our day frequently reveal the severe limitations in our human cognitive abilities - our many severe biases and blind spots. 100s of years ago, when we thought we were doing well to survive the day and have a hot meal in us at the end of it, we thought we were the sharpest tool in the box and made in the image of an omniscient creator. Now, when the shit is really hitting the fan, our true nature as no more than unusually adaptable apes on the savannah is catching up with us. Our brains were not made to solve these problems and we are duly failing to do so.
Desertificatin is increasing? Please document this. The Sahel is greening and most other arid climates are greening also because of CO2 enrichment.
The stomata of plants in arid regions open to gather in CO2. While open the plants emit H2O until the CO2 levels are satisfied. With Higher CO2 levels the stomata do not have to stay open as long and the plants lose less H2O and grow bigger, faster, with less water. It is the exact opposite of what you claim. Here is a book that describes the main causes of desertification, i.e. change in an area caused by human factors. most are not caused by CO2 increases limiting water in an area. https://www.amazon.com/Progression-Desertification-Ashgate-Environmental-Practice/dp/0754643239

Compare the expertise it takes to get something so basic, so horribly wrong, and you'll understand why you can't take a single thing related to resources from these folks seriously.
