Go and calculate the mass of ice on Greenland, and its latent heat of melting, and divide that by a hundred years and tell me that somehow the sun is going to provide that level of excess energy to the planet .

    As I said elsewhere, I don't see Greenland melting
   anytime soon. 'Climate' suffers 'cooling periods'
   roughly every 500 years - often driven by massive
   Indonesian volcanic events (sometimes asteroids).
   Iceland may sometimes play a role.
    I think Greenland is mostly 'cycling' - right now
   it's slowly melting but sometime soon the climate
   may change a few degrees and it'll build up a lot
   more ice again.
 

The ice age didn't end in a century. In fact it hasn't ended, technically. We are in an interstadial.

    Well ... the 'main part' of the last ice age DID
   end pretty abruptly in terms of geological time.
   Nobody is sure exactly why - all the factors that
   co-contributed. My GUESS is that sea levels got
   low enough to destabilize the methane hydrate
   deposits. There may be proxy evidence - we'll see.
 

But the point is it took thousands of years for the ice to melt.

    Well ... more like maybe 1000 years.
 

While the Younger Dryas feature abrupt and massive atmospheric  climate change over a few decades - way more than any modern warming or cooling - it did not immediately melt all of the ice.

Shows the actual sea level rises and the full de glaciation took *over 6000* years.
And continues albeit at a far slower pace, to ythis day.
Mountains of ice do not melt in a day, or a week, or a decade or even a millennium

   The bullshit "world flood" then happened
   as ice-dams and such failed and sent Huge
   quantities of water down river tracts in
   the northern hemisphere. I can see why so
   many people imagined the entire world was
   flooded.
    Thing is, the last Big Freeze happened really
   quick too. SOME evidence points to an asteroid
   hitting arctic Canada or Greenland.
 

IT may have heppened quickly, but the ice did not form overnight.

   All the causes/equations are difficult, hard to
   pin down, but not impossible. 25 years from now
   we'll have a much better picture. Might even be
   able to take advantage.

The main facts are known. No matter what happens in the atmosphere, miles deep ice sheets to not melt overnight, and nor does deep permafrost.
You have to be particularly ignorant of physics to believe otherwise.
