L-17 - Climate change occurs naturally - albeit slowly.
10-12K years ago - the last Ice age was ending - during which manhattan was covered with ice nearly half a mile thick.
earth has gone through multiple climate swings - from Ice ball planet to waterworld.
Climate changes - and teh world is warming - just how much is natural change and how much is man and carbon producetion - is unclar - and the radical fascist DPST's just know they already solved the problem with AOC's soylent green new Deal - despite the non participation of eh rest of teh world.
Scientists contend that at least two
Snowball Earth glaciations occurred during the Cryogenian period, roughly 640 and 710 million years ago. Each lasted about 10 million years or so. The main evidence of the severity of these events comes from geological evidence of glaciers near the equator.

What would the Earth look like with no ice?
For years, scientists have thought that a continental
ice sheet formed during the Late Cretaceous Period more than 90 million years ago when the climate was much warmer than it is today. Now, researchers have found evidence suggesting that
no ice sheet formed at this time.Sep 24, 2013

Yes. Earth has experienced cold periods (or “ice ages”) and warm periods (“interglacials”) on roughly 100,000-year cycles for at least the last 1 million years. The last of these ices ended around 20,000 years ago. Over the course of these cycles, global average temperatures warmed or cooled anywhere from 3° to perhaps as much as 8° Celsius (5°-15° Fahrenheit)
In New York, the
ice that
covered Manhattan was about 2,000 feet high before it began to melt in about 16,000 BC. The
ice in the area disappeared around 10,000 BC. The ground in the New York area has since risen by more than 150 ft because of the removal of the enormous weight of the melted
ice.
