How would I show to what extent do temperature changes over the past 50 years in Vancouver support evidence for global-warming?

Look at the local history records

Start at the IPCC website referenced below. See how trends in Vancouver correlate with any claimed global trends. Readings in Vancouver alone are totally irrelevant, except insomuch as they can be combined with readings all over the globe. Many, many things influence local temperature. It is extremely difficult to take global measurements and determine whether there is an overall trend, on a timescale shorter than geologic.

Doing that is not scientific. Temperature in one place says absolutely nothing about global warming.
There's a global warming skeptics site somewhere that searches weather records , finds places where temperatures have gone down, and say that the temperatures in Anytown, Kansas prove global warming doesn't exist.
Don't play that game, it's ridiculous.

You have to obtain weather records for the last 50 years.
