Here's my take on things, wether we are in on it or not, we are coming out of an ice age, things will get warmer. from what i have read and seen (History channel, discovery and science channels) It was much warmer in dino day's, so things will get warmer. My take on how we fit is a bit different, we are destroying our environment, but the way they (environmentals
) say. the stuff that destroys the ozone and contribute to global warming are heavier than the air we breathe, While it may contribute to heating, it will displace the air more (molecules over atoms). In order to get them high enough to really cause the warming they are worried about, we either have to displace the air, or blast them up into the upper atmosphere. Only one thing regularly sends greenhouse gasses that high, Volcanoes. We have tall chimneys in industry and jets but they don't do as much as volcanoes supposedly do into the upper atmosphere. Form what i have read and seen, we may be contributing , but are not the primary cause of Global warming. I would like to see electric cars and green energy, but i think we need to research more before buying into the right one
