As I see a new brave offensive against those devious satanic gasses and obviously, weather of mass destruction is about to destroy the world. So, perhaps it's time to review the science behind greenhouse warming. How about using the scientific method this time. It seems to be getting warmer, Glaciers are melting, earthquakes in Alaska, etc. whatever. Well we know the greenhouse gas effect and we know that CO2 is rising. So could the increase of CO2 be the cause? So if increase of GHG is causing the warming. More GHG is more warming so we can model several scenarios leading to a prediction of the temperature in the future. Here is one. The complete story here And indeed we have covered a few more years since 1998 and we know the outcome. If we merge the two (red dots and the boldface trendline) we will find that we rougly have approached scenario C instead of A or B. But did CO2 stopped increasing in 2000 and did we have large volcano eruptions? Prediction failed (or at least increasingly inaccurate) What now?
