Spathi Posted November 23, 2022 Report Share Posted November 23, 2022 It is known that due to global warming, the average temperature on Earth over the past 100 years has increased by 1.2 degrees. At the same time, I heard that earlier the temperature of the Earth was 7 degrees higher than the current one. I do not deny the danger of global warming, because I have seen mentions that not only the concentration of CO2 is important, but also the rate of its change (with the current rate, the ecosystems do not have time to react), and also that positive feedback can work now (the ocean, heating up, releases steam, which is also a greenhouse gas). But I would like to see these points explained in more detail. I also heard that 500 million years ago the concentration of CO2 was 6000 ppm, and with this concentration, a man suffocates. Is that true? Quote Link to comment Share on other sites More sharing options...
