Think about this. Before the Ice Age the Earth REALLY didn’t have much cold winters. The weather before the Ice Age allowed vegetation and trees to grow all the way up in Alaska and all the other places that are now cold areas of the Earth. In fact I believe we didn’t have much cold air around the world at all before the Ice Age. The Ice Age gave the planet all the ice we have seen on the North and South Poles and all the glaciers around the world. There is NO WAY Mother Nature can reproduce the amount of ice again again around the world as it did when the Ice Age happened. A super volcano somewhere on Earth erupted millions of years ago and all it’s volcano ash block out the sun for many years which then caused the Ice Age. The ONLY way the Earth will be able to have as much ice as it did before the current global warming started in 1960 is for the Earth to experience another super volcano eruption.
Because of global warming the Earth is headed for the way the Earth was before the Ice Age. Unfortunately we humans will in no way be able to survive as we do today in that kind of world which has no cold winters! Farming like we have today will not be possible anymore because the Earth will be getting much less rain. The Earth’s water will evaporate from the heat of the Sun. Streams and rivers will first quickly disappear as all life around it either dies or go on a constant move looking for livable areas on the planet. Mass chaos by people worldwide will only add to everyone’s problems as humans and animals fight for whatever is left on Earth for them to survive. Insects will drastically multiply and kill millions of people and animals as the insects spread their diseases worldwide.
Some now think that the Earth will evolve to how the Earth was before the Ice Age once the North and South Poles and the glaciers around the world are melted. That will not happen because before the Ice Age there was mostly trees and vegetation around the world. That is not so today. Also the earth atmosphere had a lot more oxygen and moisture in the atmosphere to sustain a world with as much trees and vegetation as it had before the Ice Age. And I doubt if the winters were as cold worldwide before the Ice Age as they were before 1960 and even today.
