Help! I need old METAR archives for a project

[EXTspotter]

Hey, I am doing my A levels at the mo and one of my options is "Extended Project" which is writing a dissertation on a subject of your choice. I am doing on how the growth in the movement of people around the world has effected the weather in any obvious way. The most obvious data source I can think of is METARs, and I was wondering if anyone knows of anywhere I can get archived metar info from. Preferably from the atlantic facing part of europe. Thanks!

If your looking that long term, get rainfall data or something along that line instead.

Rainfall data isn't enough, I need an entire summary of all atomspheric conditions, METARs provided the best base for it. I found wunderground.com which is great, as it goes back to 1996. Which can give a general trend over 12 years, plus I have details of all NE Atlantic storms going back to the 1950s, which I can compare with todays storms to see any difference.
