It's not that the earth's changes don't influence weather, it's that man is influencing it in a negative way and our living conditions and quality of life is being drastically altered so much so, earth could be unlivable for man. The earth will still be here, it's us that might not.
I don't understand how people like you don't get that it's not just you on the planet or your family and friends, it's the other 7.53 BILLION on the planet that make the difference with you. And that population is growing fast.
