First, the obligatory comment regarding Climate Change: anyone who wants to reverse "Global Warming" is an uneducated idiot, ot a diehard, elitist Communist/Socialist, who believes they will be among, and at the top of, the U.N.'s "ideal world population" of 500,000,000.
Looking at those teeth, after 40,000 years, I want that guy's dentist's number. Unbelievable a Brit had such good teeth, so that proves it had to be a tourist.
Fortunately, humans really can't influence climate in any significant way or those morons would have us descending into an ice age prematurely.
