May want to take a look at this video. It was characteristic of the late 1970s 'the ice age' is coming scare. Since it wasn't real, and since there was nothing we could do about it anyway, it simply died off. I guess it got warmer.
The science is mostly right ... and we would be wise to heed it today.
Someday the ice will return -- The cycle of glaciation started apparently when the Isthmus of Panama became blocked, rose above sea level, pushed by plate tectonics. Said to have happened about 3 million years ago when the flow became totally blocked, this triggered the approximate 100,000 year cycle of glaciation and warmth we still have today. The last glaciation period, which ended about 11,000 years ago, covered most of North America with glaciers many thousands of feet thick. Now that's climate change you need to look out for.
Yes today we are in an interglacial period, the Holocene period, interglacial periods last for about 10,000 years.
