to help put it into a perspective for those that believe the earth is only several 1000 years old (which i don't believe but understand that other's may), a lot of the evidence that global warming is happening now at an alarming rate is based on information from the last 1000 years.

you only have to go back to pre industrial times (1600s) to see the changes with increasing GHG emissions.

also 10 of the hottest years in the last 1000 years have occurred in the last 15 years.
