Latest Global Average Tropospheric Temperatures
Since 1979, NOAA satellites have been carrying instruments which measure the natural microwave thermal emissions from oxygen in the atmosphere. The intensity of the signals these microwave radiometers measure at different microwave frequencies is directly proportional to the temperature of different, deep layers of the atmosphere. Every month, John Christy and I update global temperature datasets that represent the piecing together of the temperature data from a total of fourteen instruments flying on different satellites over the years. A discussion of the latest version (6.0) of the dataset is located here.
The graph above represents the latest update; updates are usually made within the first week of every month. Contrary to some reports, the satellite measurements are not calibrated in any way with the global surface-based thermometer records of temperature. They instead use their own on-board precision redundant platinum resistance thermometers (PRTs) calibrated to a laboratory reference standard before launch.
Y'all have seen this. I try to check it each month.
It is interesting that the head of the project is Roy Spencer, who isn't sure the warming is caused by CO2. Here's what he has on the site on Global Warming
...
The case for natural climate change I also present an analysis of the Pacific Decadal Oscillation which shows that most climate change might well be the result of….the climate system itself!
...
Spencer has also written about Evolution: Testing Truth with an Open Mind
...
The possibility then presented itself that, despite all I had previously thought, Genesis, the first book of the Bible, might actually be true!
...
Most scientists think that question is fundamentally outside the realm of science. I'm sure he also realizes that.
