ice age due to
melting of
glaciers, it is quite possible that a great many civilizations did decline or perish due to warming, and in fact perished so thoroughly that there is no trace of them.

melting, and weather is not getting more extreme.
What is known is that during the period called Little
Ice Age, global glacial were advancing, and starting around 1850, instead advancing global
glacier became retreating, this trend of glacial retreat continues to the present time, but not all
glaciers adding during the Little
Ice Age have not yet
melted.
If you get some guages from Alaska they will actually show a long term decrease in sea level since there is strong isostatic lift (increase in land height) due to the

glaciers from the
ice age.

The Polar bears stubbornly refuse to go extinct, indeed the buggers are thriving, the
glaciers don't appear to be disappearing, sea levels have stayed boringly level, we haven't been subsumed by hordes of desperate climate refugees, the polar
ice caps haven't
melted, the Great Barrier Reef is still with us, we haven't fought any resource wars, oil hasn't run out, the seas insist on not getting acidic, the rainforest is still around, islands have not sunk under the sea, the ozone holes haven't got bigger, the world hasn't entered a new
ice age, acid rain appears to have fallen somewhere that can't quite be located, the Gulf Stream hasn't stopped, extreme weather events have been embarrassingly sparse in recent years and guess what?
In the case of the 100 kyr
ice age cycles, that forcing is high northern latitude summer insolation driven by predictable changes in Earth's orbital and rotational parameters — aka, Milankovitch theory — which has the intial effect of
melting glaciers, thereby reducing albedo at those latitudes.
