1) No, no local or short-term weather is ever going to falsify or prove anything about the global average. 2) Assuming you are already convinced by the science that the global average temperature is quickly rising; one might ask: What are the consequences? And one of the consequences is more extreme weather, as there is more energy in the weather systems.. 3) So one may point to extreme weather events and say "in the future, we'll have more of those, and that's why we need to stop emitting CO2". That doesn't mean the weather event is proof of global warming in any way -- it is just pointing to an illustration of what will happen if global warming continues; as measured by the GLOBAL temperature.
