The icesheet has remained intact for longer than that. You should avail yourself to the the ice cores of GISP and GISP2. Obviously, you are confused about shoreline snow & ice and the ice sheet of Greenland (several KM thick)MSimon wrote: And yeah just a thousand or so years ago when the Vikings farmed Greenland the seas must have been higher. Their villages are now under ice. Doesn't any one care about Vikings any more? That is an extinct species for sure.
Yes, nobody disputes natural variability with temps changes caused by solar and Milankovitch cycles. CO2 lagged these natural changes as Biota flourished/died. Today that is reversed with CO2 emissions leading temp changes due to thermal latency of the oceans.MSimon wrote: And you know what? I have incontrovertible proof: What happened to the glacier that used to cover Chicago? Gone. The glacier that used to cover most of Canada? Gone.

To many scientists who understand feedbacks and tipping points in a climate system and the lack of scientific understanding held by many people with the denial claims.
Many people are not interested in reducing their own carbon footprint. They take no personal responsibility for the contributions to a problem, so they deny it is a problem so that I guess they can mock others who do care.MSimon wrote: I'm going to send Al Gore all my spare change.
