I would have thought that common knowledge of CO2 as a greenhouse gas and its increasing quantities in our atmosphere would give anyone a good kick up the backside trying do deny global warming. This is grass roots science, its not LHC particle detection. No need to realise that greenland is thawing at ever accelerated rates, icesheets, permafrost are disappearing. Our oceans are absorbing much of this, a secret pollution that is changing state of its biodiversity. Take a look at this

So what if there are some people not giving facts entirely so clean cut. We need reaction to dangers of sloppy, lazy human behaviour on NOT acting, not endless political like debates on science fracture of fact. Its real, deal with it. Grow up and be responsible.
