“Global Warming?”

Here is an updated graph of the ENTIRE satellite record of global average atmospheric temperatures. I’ve been carefully tracking these measurements and discussion since the early 1980’s.

In short, the graph illustrates that the average temperature of the lower atmosphere is steadily increasing at a rate of about 1.3 C per 100 years, essentially unchanged for hundreds of years (since the ‘Little Ice Age.’)

The graph calls out that the average December global temperature was only five hundredths of a degree Celsius above the 1991-2020 global temperature average, essentially a negligible difference from the thirty-year average (within the noise).

Note also that the averaged natural variations (red curve) are on the order of half a degree, that the lowest averaged temperature in the forty-three year record is about -0.5C, and that the maximum averaged temperature is about 0.4C, while the un-averaged (noisy) values range from -0.7 to 0.7C.

Stated simply, the natural monthly noise is about twice as much as the natural variations, which are about ten times as large as the difference we currently observe from the thirty-year average.

Why is this result important? Because this is the precise portion of the atmosphere that was supposed to be dramatically affected by anthropogenic global warming. Clearly, no such effect is observed, and if there is any net human effect, it is dwarfed by the natural variations and the noise.
