All that global warming and nothing to show for it?
Headlines rang out telling Australians that last summer was the hottest ever. But, according to the UAH satellite series, the hottest — just barely — was in 1991, when CO2 was a wonderful, safe 356 ppm. Since then, humans have emitted more than half — fully 58% — of all the emissions we have ever emitted since we crawled out of those dank caves. CO2 levels are almost 50 ppm higher now, and temperatures are almost as high.*
Wonder if this summer will get close to the summer of 1991 (and we wonder if Victoria will keep the lights on).

The UAH data comes from NASA satellites, which cover all the Australian land mass every day and night.
The BOM (and NASA) prefers to use Australian ground data which is based on sparse thermometers that keep changing sites and equipment, are located near airport tarmacs, buildings, and cars. When readings are too cold, the BOM sometimes deletes them. Temperatures from thermometers hundreds of kilometers apart are magically homogenized and “corrected” through a secret computer process and two thirds of our warming comes from those adjustments, not from CO2 […]
