Satellite Data Show No Warming Whatsoever In Lower Atmosphere For Last 7
Years

February 7, 2008

http://www.worldclimatereport.com/index.php/2008/02/07/more-satellite-musings/



About a month ago, we ran a piece reflecting back on the behavior of the
satellite-derived temperature history of the earth's lower atmosphere
for the past 10 years or so. We commented that the two major
realizations of the temperature history of the lower atmosphere-one
derived by researchers at the University of Alabama-Huntsville (UAH) and
the other by researchers at Remote Sensing Systems (RSS)-seemed to be
drifting apart in recent months. Well, it has since been determined that
a slight computational error involving the data for 2007 had been
introduced in the RSS routines, and this error has now been corrected
(see here for more detail) so all is now well again in the world of
satellite-derived global temperatures-or is it?



Yes and no.



Yes, if you are interested in the inner workings of how the satellite
data are combined to produce temperature values of the atmosphere and
how the two different research teams use slightly different
methodologies to produce their slightly different temperature histories,
but overall which are by and large very consistent. In other words,
things are working correctly again. Figure 1 shows the record of monthly
temperature anomalies in the lower atmosphere averaged for the globe for
the RSS and the UAH data sets during the period January 1979 through
January 2008. Notice the very close correspondence. Figure 2 shows the
actual difference between the two data sets (UAH data minus RSS
data)-and these differences are well understood. Comparing Figure 2 with
the lower panel of Figure 1 from our January 8th posting and you will
see that the large discrepancy that used to be present at the end of the
record (in 2007) has been resolved.

January 2008) of the lower troposphere as produced by researchers at the
University of Alabama-Huntsville (UAH, blue line) and from Remote
Sensing Systems (RSS, red line).

RSS).



But the answer to 'whether all is right' is 'emphatically, no!' if you
are looking to the satellite-derived temperature datasets to find
evidence of a strong warming signal in global temperatures over the past
several years. In fact, both the RSS and the UAH temperature records
show that January 2008 was below the long term (1979-1998) average for
the month. This is the first time since January 2000 (exactly 8 years
ago) that both records were colder than normal. Figure 3 shows both
records from January 2001 through January 2008 and illustrates that over
this time period-more than 7 years, during which time global emissions
of carbon dioxide have increased by probably 15-20% (the actual data are
only available through 2004, but the emissions growth from 2001 to 2004
was over 11% and we doubt things have slowed down any, see here for
data )-there has been absolutely no warming whatsoever in the lower
atmosphere. In fact, global temperatures were 0.63ºC cooler in January
2008 than they were in January 2007. Such year-to-year variability is
not particularly unusual (note that a similar drop occurred in the
middle of 2004), but it is interesting nonetheless in that it certainly
doesn't lend itself to thinking that the lack of warming during the past
7 years is letting up anytime soon.



Figure 3. Global average temperature history during the past seven years
(January 2001through January 2008) of the lower troposphere as produced
by researchers at the University of Alabama-Huntsville (UAH, blue line)
and from Remote Sensing Systems (RSS, red line). There is no overall
temperature change during this period.



We can't imagine that the global temperatures will stay down forever,
but the last 7+ years does provide a clear example that the rate of
temperature change is not simply going up and up and up. In fact, the
rate of change seems to be slowing.



Stay tuned to see how global temperatures develop over the coming
months. Things look to be getting interesting.
