OK, so I'm having a hard time convincing the likes of epicyclo that Climate change is happening, largely because the discussion turns into an endless discussion about whether scientists can be trusted or whether computer models really work.
There also seems to be a view that until climate change is made "simple" for people to understand that it won't be taken seriously.
So, I found this presentation that actually lets you see some of the physical evidence regarding retreating glaciers for yourselves.
