Thank goodness someone else gets it. Yes, the Earth has been warmer in previous times. The ice melted and coastal areas were flooded by inland seas. Of course future generations will have to pay to move coastal cities, build massive dikes, etc. to deal with the flooding because the changes are slow on a human time scale. Why should we worry? We won't be around to see it. So party on, pump more CO2 into the atmosphere and saddle future generations with the expense of our bad habits.
