Oh my... So the reason that there is no global warming is because there are BBQs ? So, all the signs that can be seen are bogus...

The fact is, that Surface temperature recording stations are a tiny part of record keeping.There are stations on ships and buoyage, airplanes, radio probes AND satelites (no danger from BBQs there)

Not to mention that other nations & continents might have better national science institutions...
Just see how many stations there are:
