The Satellite Record 1979-2002 

The new way to determine global temperature is to use satellites to measure the temperature of the lower atmosphere, giving the Earth a uniform global sweep, oceans included, with no cities to create a false warming bias. This second method, used since January 1979, is accurate to within one hundredth of a degree,  and is clearly the best record we have.  Here is Global Mean Temperature (anomalies in C) of the Lower Troposphere (lower atmosphere) for the 23-year period January 1979 to June  2002, as measured by NOAA satellites. It shows a very different picture to that of the global `surface record' over the same period.



Global trend per decade = +0.064C,    (Northern Hemisphere = +0.136C,     Southern Hemisphere =  - 0.008C.)
Global June 2002  =  + 0.2C, (Northern Hemisphere =  +0.217C,    Southern Hemisphere =  +0.183C.)

 

 

Here are the annual averages for the full satellite data period 1979-2001.

1998 stands out as an anomalous year from the rest, caused entirely by the big El Nio of that year.  1998 alone is responsible for the `warm' statistical trend of the entire 23-year period.

2001, which CRU and GISS claim is the `2nd warmest year ever' is actually only the 9th warmest since 1979 when measured properly by satellite.

The actual data from which the above graphs are derived.
  Northern & Southern Hemispheres compared.

A comparison of the two data sets are shown here.  The two sets are referenced to a common zero (as at January 1979) to compare subsequent relative trends.

Notice the growing divergence between the two. However, over the USA and western Europe, both surface and satellites agree with each other at the regional level. This suggests the global surface record is exhibiting a false trend due to inferior non-OECD station records and urban heat island effects in city records.

An argument for an independent review of the `surface record'. The satellites were reviewed, so why has the `surface record' escaped an independent examination in the public interest?
