Afew scientists say global warming is largely due to a natural cycle. what is some evidence of the natural cycle? humans have lived in areas with extreme temperature ranges. humans once settled in areas now covered by glaciers. humans have farmed in certain areas for centuries. humans have long settled in areas with tropical climates.

answer: the truth is, global warming is hoax

explanation:

it's not a real thing, these scientist study and do research on global warming for money. if you think about it, humans have only existed for like 3-5 thousand years. the glaciers melted over 7 million years ago. the earths core is actually expanding and heating. the sun is also expanding because it's getting older. we are not the reason, the trees absorb the carbon dioxide produced by our cars and mouth, the trees use it carbon dioxide to produce oxygen.
