Not so long ago, scientists believed that global warming was caused by human actions alone, which they had a good reason for, as the earth has been changing a lot since we first invented cars and started using fossil fuels. The earth’s changes happened in a pattern with the increase of CO2 emissions from humans that came from cars factories and more. This led the scientists to come up with their theory. However, lately scientists have pondered upon a new discovery, which they say reveals that global warming is not caused by our actions, only sped up by them. Apparently, global warming is now a result of a natural cycle of the earth, which occurs every now and then, in a cycle with ice ages. Scientists now believe that after an ice age, it is natural for the earth to go into a heating phase, where it warms up before cooling down again for another...
