1 They are assuming that if the global warming theory is correct, only a particular causal outcome is to be expected, namely and crudely that everything and everywhere warms up, there are universal rises in temperature. It's a brutally simple application of modus tollens :

i. If p then q

ii. not-q

iii. Therefore : not-p

If there is global warming (p) then there are universal rises in temperature (q)

There are not universal rises in temperature (or we wouldn't have major unexpected snowfalls) (not-q)

Therefore there is not global warming (not-p)

2 WhatThis misrepresents the global warming theory which does not hold that there are universal rises in temperature but only that there is a general and persistent rise in average temperatures.

3 That aside, what this type of argument plainly and slightly infuriatingly omits is that global warming involves multiple causal mechanisms by which a general global warming can cause local downgrades in temperature.

I am not sure if there is a specific term for the kind of false reasoning you describe but there does seem to be an error of over-simplified causation.
