It seems YOU have almost no idea how climate changes/work.The Ice Ages began 2.4 million years ago and lasted until 11,500 years ago. During this time, the earth's climate repeatedly changed between very cold periods, during which glaciers covered large parts of the world, and very warm periods during which many of the glaciers melted.
Earth about 4.5 billion years old. Just look at the Ice Age [2.4 million years] and explain the ups & down of temperature [note: sea level changes]
And try to think of what caused these rapid changes. Seems we have almost no idea how climate changes/works.
Pollution obviously bad.
Luckily that’s an easily fixable problem unlike climate change.
