Thoughts...
1) @Superstitious git "f you follow the logic of your comment... the CO2 stops heat from candle getting through...How does the SUN's heat get here in the first place??"
well, simple. CO2 blocks rays with a heat strength of less than 7 arbitrary units. Rays from the sun come in a 10 arbitrary units, bounce off the earth where 5 units are converted to other energy. The rays then attempt to leave at strength 5. These are blocked by CO2 and so remain, causing heating.
Ever parked a car in hot sun? noticed its hotter inside than outside? same thing. Or how about gone inside a greenhouse? both the same thing, hence why its referred to as a "greenhouse effect" clever eh?
2) I don't believe we have ANY idea what will happen to the climate in the future. We can't predict conditions in the next 24 hours accurately, you expect me to believe predictions for 10 years? I keep seeing reports of "cow farts are causing global warming" "nuclear blasts stop global warming" "soot stops global warming" "burning coal causes global warming". Until I see someone say "the combined effects of cows, co2 and wasted heat are (not) countered by the effects of soot, nuclear blasts etc" I'm not going to be convinced either way.
