"The CO2 content of the atmosphere is measured continuously. This fluctuates with the seasons, but the average value increased from 285 ppm in 1900 to 365 ppm in 2000, a relative increase of almost 25% (ppm = parts per million by volume). Temperature measurements have been used to see whether the average temperature on earth has in fact increased. To that end, the measurements collected at all weather stations around the world are averaged in a particular way (day and night, every day of the year, across the earth's entire surface). The IPCC reports a significant increase of 0.6°C during the twentieth century. This comprises an increase of 0.45°C in the period 1900-1930, a fall of 0.2°C in the period 1930-1975, and an increase of 0.35°C in the period 1975-2000. This last increase, which corresponds to 0.15°C every ten years, coincides with an observed increase in the CO2 content."
So, CO2 increased but temperature decreased from 1930 to 1975. Until you and the models can explain that, then it's idiotic to depend on the models to predict what will happen in the future. If the model can't reflect the real world, then the model is broken, not the world. Too bad that seems to fly in the face of your political dogma.
