According to USA Today, NASA says “modern climate change” is caused by the burning of fossil fuels.
So what caused the last 4.5 billion years of climate change?
“The climates of the earth have always been changing, and they will doubtless continue to do so in the future. How large these future changes will be, and where and how rapidly they will occur, we do not know.”
