I am an odd mix of contrarian and geek so im gonna ignore the social convention of sticking to your qualifiers and comment regardless,lol. Have human industries had and continue to have an effect on the weather and climate? Sure OfC they impact it. Overall though will it end all life on the planet? Nah, we have had 20 degree swings before in either direction.

Sure it would wreck island nations and coastal communities, thats not new either. We have to adapt, pursue newer technologies as they become viable..AS LONG AS THEY ARE NOT AS DESTRUCTIVE AS THE ONES THEY REPLACE! ( sorry pet peeve there ).. and then eventually get off the planet if we are serious about REALLY saving it.
