Earth’s climate has always changed. 12,000 years ago most of North America was covered in over a mile of ice and the oceans were 400 feet lower! America has been warming ever since. We will continue to warm or we could go back into our current ice age.
Ice ages are bad because food doesn’t grow well and billions of Humans will either starve or freeze to death. Warming is good because we all live and prosper.
There is absolutely no evidence that Humans cause global warming. In fact, only the stars know if it will get hotter or colder and it is all up to that one star we call our sun.
