GW is not some entity that somehow "causes the earth to warm;" warming is an effect, not a cause or catalyst. That's why it irritates me when people use that weak-ass argument, that "we get hot weather every year, that means that global warming is not notable." Nobody's saying, "it's hot, therefore global warming," so I don't understand why anyone would even use that terrible argument in the first place. The argument is that we're seeing a continuing upward trend in temperatures, with records being broken almost every year, and that this indicates that the earth's average temperature patterns are rising gradually.
Global warming is a catalyst, not a cause unto itself.
"Gradually" being a relative term; in a literal sense it's gradual, but on a geological timescale it's actually rather quickly.
For all the things that I never did
For all the places I never was
For all the people I never stopped
But there was nothing I could do..."
