a brief look at history will show you times of bitter cold in summer months and terrible heat and drought in winter months. No meteorologist data though so we base our numbers on what? the last 100 years? Not good enough...

No need to have 100-500-etc years of data to see wtf. we have the air pollution / air component data for the recent decades and this is perfectly enough to see what we did to the air. glass-house gas percentage is high and its bad.
most of you don't know that its NOT about it will be higher/lower temperature at certain/all places, the main effect of this is the change of classic/constant 'streams' like the Gulf Stream: if the sensitive system of these are changing because of minor climate changes than it Will result in a major change in Earth's climate.
The other thing is that the debate is not about if there is a climate change or not. The question is if human activity in last decades matter or not. The biggest polluters like China say the climate change is independent from what we did/what we do.
Sorry if I am not using the proper phrases in the sentences above, most of these terms i only know in hungarian :P
