global warming is just a cycle. it happened thousands of years ago, and its happening again
Some context is needed here. A couple billion years ago, early methanogens, who were at the time the dominant life form on Earth, caused so much global warming it killed them all off. These bacteria now exist only in geothermal vents at the bottom of the ocean. This allowed cyanobacteria to take control and fill the Earth with oxygen. Fast forward to a few hundred million years ago, in the Carboniferous period, when the dominant form of life was carboniferous plants. These replaced CO
2 with O
2 to the point that they caused massive global cooling and killed themselves off. Now we burn the fossils of those long dead plants as coal and oil and are returning all of that carbon to the atmosphere, thereby increasing the temperature. Why is this so hard to get?
