No. A typical denier is not set for farming or any other kind of adaptive change. He/she does not think that adaptation and or change is needed. Their thinking is "No problem; no need to change or prepare for the consequences; since there is no problem to begin with."
Their thinking is sort of like that of the White Star Line managers who decided that the Titanic didn't need as many life boats as the naval engineer who designed the ship said she needed and so reduced the number by two-thirds. I can almost hear what someone said in the board meeting when that decision was made, "Lifeboats! Why go to all that expense. The Titanic's not going to sink!"
The religious people who think that Global Warming is real, and that it is a necessary agent of the Famine during the Tribulations aren't interested in preparing either. They expect the so-called "Rapture" (which is a complete fraud and heresy cooked up by a succession of crackpot preachers starting with one named Darby in the 1820s) and won't be on earth to face the consequences.
Realists are the ones who anticipate disasters, try to head them off, and prepare just in case.
Thanks for the explanation.
