CO2 should affect each and every station on earth the same. It is radiative and the effects should occur at the speed of light. Over the past century, we are told, the earth has warmed by around .84 degrees centigrade, all due to CO2, which is all due to human effort. So, if that is the case, we should see warming almost everywhere over the globe. But we don't see that. We certainly don't see it at Darwin, Australia.
The degree-days have consistently declined at Darwin, Australia. In 1883, there were 10,441 degree-days at Darwin. Remember that a degree-day is the multiplication of the average monthly temperature times the days in the month, and then the months are summed up for each year. That give 10,441 degree-days in 1883. But in 2008, after there is almost 100 ppm more CO2 in the atmosphere than there was in 1883, we find that Darwin, Australia is cooler by over 300 degree-days. In 2008, there were only 10,103 degree-days. Darwin, Australia was cooler.
So much for the predictions of those silly global warming hysteriacs
