Can you recommend a URL that lists these, as I'm trying to convince a
sceptic that the world's temperature *is* rising.

Hi Paul
It depends how much your sceptic knows. There are different ways to measure
the world's temperature e.g. the surface record, satellite observations,
weather balloon obs but the data all require certain corrections and / or
extrapolations such as - in the case of the surface record - corrections for
urban heat island effects.
The problems come when experts start arguing over whether the corrections
are correct or not! The data set for the (satellite measured) monthly mean
lower troposphere temperatures is at
http://vortex.nsstc.uah.edu/data/msu/t2lt/tltglhmam_5.1 and that shows a
global decadal temperature trend of a mere + 0.077 C which may not impress
your sceptic overly when he/she recalls some of the scare stories in the
media.
Your best bet is to concentrate on figures from the surface record that show
a much steeper temperature rise so you would do best to use the links that
Martin Rowley has provided and try not to get sucked into an argument about
why the surface record trend is greatly different to the satellite measured
trend and the balloon observed trend (if your sceptic should be aware of
this). Anyone who can solve that puzzle conclusively will be on the way to
settling the global warming debate.
