Actually I still don't get, why people would see a conspiracy behind global warming. Just read an article some days ago, that while the global temperature difference in the last 10 years was 0,0 %. If you read this you would say: "Wow, global warming must be a hoax". And then you think about it.
A.) Not as many stations in the arctica and antarctica and therefore flaws in the calculation methods of the measurement, while the ice is definitely shrinking. B.) Imagine the gulf stream disappearing - I'll bet Ireland and England won't have palm-trees on the shores anymore - therfore there no higher temperatures.
By the way the Copenhagen Diagnosis is out http://www.copenhagendiagnosis.com/ And this says, that the warming could happen faster, than we think.
I'm not an expert and leave this to them, but undeniable facts are: 1. mankind boosts out more Co2 and the alike then ever before in history (of mankind) 2. Co2-killers like primary forests (=natural eco systems) have never been less in history (of mankind) 3. over short or long oil, gas and uranium (therefore nuclear power planting is not alternate) will run out 4. icebergs in the arctica/ antarctica and glaciers are melting (compared to the time, when we started to take scientifical notice of them)
Wether this leads to dangerous global warming or not - I frankly don't know, but if this leads to it, we or at least some billion humans are more or less fu***d.

Actually global tempeture is now measured by sattelites... and has been coincidentally for the last 10 years or so. Well more like 15. Since the early 90's.
Tempeture stations were a giant problem though. For example they had next to zero stations on 2/3rds of our planet. AKA Water.
As for why people think this... go to the link and read to the emails where they talk about very unscientific ways of doing things to prove stuff they couldn't prove and that the data seemed to show otherwise.
