A few years down the track might prove anything at all other than rising temperatures which will be pronounced at the poles.
What obvious damage to the environment do you believe will be revealed? I've seen German works translated into English from a century ago which point out once atmospheric CO2 rises above 800 ppmv then man and his mammal relatives will be slowly snuffed out. This was a time when AGW was only popular in Germany and Scandinavia and ignored in the English speaking world.
But beyond this there may be no obvious effects. The final melting of the ice caps could take anything up to 40,000 years. Even 200 years hence we may only see a general rise in ocean levels of about a meter.
