How to look at the RSS satellite-derived temperature data: has the earth warmed or cooled?

It’s already well known that the Remote Sensing Systems satellite-derived temperature data has released the January figures: the finding is that it’s colder this January than it has been for some time. I wanted to look more carefully at this data, mostly to show how to avoid some common pitfalls when analyzing time series data, but also to show you that temperatures are not linearly increasing. (Readers Steve Hempell and Joe Daleo helped me get the data.)

First, the global average. The RSS satellite actually divides up the earth in swaths, or transects, which are bands across the earth whose widths vary as a function of the instrument that remotely senses the temperature. The temperature measured at any transect is, of course, subject to many kinds of errors, which must be corrected for. Although this is not the main point of this article...

This is why they have changed to climate change {to easy to debunk the warming thing}

Algore wants us to buy our carbon credits like good little socialists.

One of the coldest winters on record in Colorado and certainly the coledest in the 20 years I have lived here.

And someone needs to go tell the Chinese the warming will come any day now.

Alamosa, near my hometown is usually the coldest place in Colorado and usually the coldest in the nation.

All this RSS satellite business is confusing me. We don’t need the facts, just Gore’s video. You know a seminary drop-out cannot be wrong.

It looks like there was an increasing trend for most of the series starting in 1996 to 1998, but ending in late 2004, after which the data begin trending down: for the tropics to north pole, anyway.

One thing is certain: the hypothesis that the temperature is linearly increasing everywhere across the globe is just not true.
