of the Week
(24 January 2004)
|Each week, the temperature
history of a weather station(s) somewhere in the world will be presented. Most
will be from rural sites or small towns, not the big cities to reduce the impact of errors from urban heat islands. Here is `Global Mean Temperature'
for the 20th century, based on an averaging
of mostly city-based surface stations. Note the
post-1970s warming, a warming not evident in the satellite
record of global temperature (as shown on the
See if the `Station of the Week' has a record like the global one claimed here. Both this global average and the `station of the week' originate from the same data source, the Goddard Institute for Space Studies

This week' stations are Bogota (4.7N 74.2W with 2.7 million people and the capital of Colombia), and three other stations, Neiva (3N 75.3W with 105,000 people), Calipuerto (3.4N 76.4W with 900,000 people on the Pacific slopes of the Andes mountains), and Las Gaviotas (4.5N 70.9W a rural station in eastern Colombia in the Amazonian basin).
There would appear to be little or no hope that `climate change' might impact adversely on the illicit coca crop. Very little change is evident, one station showing cooling, Bogota showing slight warming (most likely the result of artificial urban heating), and the other two with neutral trends.
On the chart below, the Bogota temperatures should be read off the right-hand vertical `Y' scale, while the other three should be read off the left-hand scale.
