... and here%26#039;s the chart from UAH%26#039;s own website:

Here%26#039;s the Register%26#039;s published RSS chart:

The difference is that when we look at the long term trend, it%26#039;s clear that1998 was an anomalous year (this was because of a massive El Niño). So starting your analysis in 1998, as the Register does, is deliberately deceptive.
The long-term trend is, and continues to be, warming.
Hadley Centre data and NASA / GISS data are virtually identical, as they must be because they draw their data from the same sources. There is always a bit of scatter between the two because they use slightly different weighting procedures, and different zero points.
Climate is LONG TERM, not short term. For a climatologist, long term means 30 years or more. Anybody who tries to sell you a story about %26quot;climate%26quot; over ten years is pulling your chain.
Oh, and one more thing: satellite observation is great for global coverage, but poor for accuracy. That%26#039;s because it%26#039;s difficult to tell the difference between the air temperature at the surface, the air temperature at 1000 feet, and the air temperature at 10,000 feet, when you%26#039;re looking down from above. And since the stratosphere is cooling as the surface warms (due to increased greenhouse effect), that%26#039;s a big deal.
There are very sophisticated algorithms to try to tease out the %26quot;real%26quot; surface temp from satellite data. UAH, in particular, has done fairly major revisions to its dataset as their algorithms have been shown to have flaws. Things are better now, but it%26#039;s still possible that these data might be subject to further improvement in the future. 0% 0 Votes
