watch the skies!

i'm all for reducing greenhouse gasses, but this has got to be one of the stupidest reasons for doing it.

it is true that an alien civilization might notice out greenhouse emissions, decide we are a potential threat and destroy the earth. it's also true that they might be looking for allies and come to give us all kinds of cool science fiction-style technology instead. we have no idea what aliens who we have never met might do, so you can always make up a story about what is possible. it's ridiculous to make policy decisions based on some completely made-up idea about what aliens who might not even exist might do.

besides, isn't it more likely that aliens would notice all the radio and tv broadcasts we have been shooting out into space over the past 100 years than the content of our atmosphere? if this were a serious threat, maybe we should ban all broadcasts?
