re: #956 avanti

I should no better,but they been useing satellites for years now.

NASA

From your link.
Unlike the surface-based temperatures, global temperature measurements of the Earth’s lower atmosphere obtained from satellites reveal no definitive warming trend over the past two decades. The slight trend that is in the data actually appears to be downward.

Second, there is a much more important greenhouse gas than carbon dioxide, namely water vapor. Water vapor over the Earth is extremely variable, both in space and in time.

First, the influence of a man-made doubling of the amount of carbon dioxide in the atmosphere is small compared to the Earth’s natural cooling rate, on the order of only a percent.
The last one is incorrect the rise is 280ppm to around 360ppm, hardly doubled.
