ascribe them to 100,000 year Milankovitch cycles...but they all came and went within atmospheric CO2 concentration levels of 180 - 300 ppm (higher CO2 <==> higher temps)...but in only the last 150 or so years our current CO2 concentration has risen to 428 ppm...and it's accelerating higher, plus, it doesn't come out very quickly...at all.

You can't flip a switch and move whole cities/populations to higher ground over night...there are huge infrastructure, economic and political implications as you should be able to discern...so it pays for us to Plan Ahead and a) reduce the magnitude and speed of change, while b) transitioning to newer sources of energy. It's a big job, but doable...especially if EVERYONE Pulls Together...(I'm looking at you, Ned).
