Spooner has that peculiar form of denial in which he indicates very clearly that he doesn't understand the least bit about what it is that he is denying. He asks:
What exactly is the relationship between CO2 and temperature?This one's easy. CO2 is the 'thermostat' controlling the earth's temperature. Turn it up and the heat goes up, turn it down and it gets very cold.
Why did the warming trend stop as it did between 1945 and 1975, when CO2 emissions took off?Spooner fails again. The global surface temperature trend is up and has been trending up for decades. This past ten years have been the warmest on record. In fact, NOAA reports that it's almost three decades since any month has been cooler than the long term average:
November 2012 also marks the 36th consecutive November and 333rd consecutive month with global temperature higher than the long-term average. The last month with a below average temperature was February 1985, nearly 28 years ago.
