The three main base data sources for climate data

From "Watts up with That":

The three global temperature records are usually called CRU, GISS, and GHCN. Both GISS and CRU, however, get almost all of their raw data from GHCN. All three produce very similar global historical temperature records from the raw data.

We know that CRU weren't impressed with GISS due to urban heat island effect not being taken properly into account ( is this the case ? Need to check ).

So that leaves only one thread left - GHCN.

Time to look them over.....

Why the science isn't settled

Richard Lindzen gives a very useful outline of why he thinks the science on anthological global warming being forced by CO₂ isn't settled in the Wall Street Journal here.

What if the data is unreliable ?

How can the world commit to drastic courses of action, just after a world recession when it seems the science isn't settled at all ?

Read: Patrick Michaels and "The Dog Ate Global Warming" - which came out before the CRU hack and #climategate.

Given how much is claimed to rely of "fighting global warming" why isn't't the evidence and its supporting arguments made in the open ?

Opening statement

This blog is part of a new project I'm thinking of starting about the climate change debate.

I've been becoming increasing concerned and worried about the political nature of the debate, and the absence of scientific debate at a political level.

I've moved position from being very concerned about global warming to becoming a sceptic, but you have to live what you preach and any good sceptic should be interested in the evidence.

So I'm starting my journey to understand what I can about the subject.

Who knows how far it will go - a long way or around the corner.

I'm a busy man, who doesn't really have the time for the political blogging I do, but we'll see. Maybe progress will be very slow.
