shoe online shops shoe online shops Are greenhouse gases good for the earth



The amount of greenhouse gases in the air before we began burning fossil fuels coal, oil and natural gas was just right for keeping the ea shoe online shops rth comfortably warm enough for life.



Since the Industrial Revolution, when we discovered that burning coal would power a steam engine, we have been adding more and more greenhouse gases to the atmosphere. This is causing global warming, which is not good for the earth.



Another Perspective: One must consider that what is good for the Earth, may not be what is good for humans, and vice versa. The Earth, after all, has been here far longer than humans, and is likely to be here long after humans are an historical footnote.



For the record, the primary greenhouse gasses are carbon based: chlorofluorocarbons, carbon monoxide, carbon dioxide, etc.; and, those other gases that reflect thermal energy: water shoe online shops vapor, methane, nitrous oxide, and ozone The current level of carbon in the Earths is around 391 ppm. One of the highest levels of carbon in the Earths atmosphere is roughly ten times that amount, at 3,950 ppm. That existed about 56 million years ago, during the transition from the Paleocene and Eocene epochs. The average temperature at the poles during this time was 55 to 68 F.



Oh! And the human infestation wasnt to occur until over 55 million years later. One has to wonder what caused that explosion of atmos shoe online shops pheric carbon before all those nasty humans started burning coal and oil. shoe online shops
