Base data on Global Warming

[Data Origin- Hadley Climate Research Unit Temperature anomaly (HadCRUT) - UK - sourced from this site]

The blog gets traffic based on 'Global Warming & Stefan-Boltzmann related searches. Seems a lot of folk are taking the trouble to do some research for themselves into the subject. That has to be a positive thing.

This site and this one, had some comments that made for interesting reading. But more to the point, it referenced the sources of the most basic data - the monitoring points for measuring the Earth's temperature. It is THAT data which should drive comment and debate, not the politics and fashion of a bandwagon effect for those who let others do their thinking for them.

So what are those sites, and what do they say.

Visit them for yourself. They are; The Hadley Center for Climate Prediction (UK Met Office), data here; NASA's GISS (Goddard Institute), data here; UAH (University of Alabama in Huntsville), (data) (A really good background article here); and RSS (Remote Sensing Systems), (data).
[NB - I'll update this with more information in days to come - but this is an interesting start - please look critically and don't just look for data that supports your perceptions].

(A UAH Newsletter had this interesting observation;
"All leading climate models forecast that as the atmosphere warms there should be an increase in high altitude cirrus clouds, which would amplify any warming caused by manmade greenhouse gases," he said. "That amplification is a positive feedback. What we found in month-to-month fluctuations of the tropical climate system was a strongly negative feedback. As the tropical atmosphere warms, cirrus clouds decrease. That allows more infrared heat to escape from the atmosphere to outer space." [Dr Roy Spencer].
