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

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.

I can solve that "puzzle" quite easily: the satellite "trend" as measured
over just two decades(!) simply does not produce any signal over and above the
noise of the readings. These are remotely sensed, derived, temperatures with
very wide error bars.

The surface record, on the other hand, extends centuries. This is a much more
accurate, directly measured - although sparse - dataset. Issues which apply to instrument changes over time, apply equally to satellite readings.

Cheers,
