How long will it be before earths average surface temperature gets up to 26 degrees Celsius?
Today the average temperature on earth is 15 C. To reach 26, the temperature would have to increase by 11 degrees. That’s a lot! But is it possible? I don’t think so. At 15 C, the air at sea level is saturated with 13 grams water per cubic meter. At 26 C, it is nearly the double. Such a moisture content will certainly increase the earth’s albedo and reduce insolation. Some believe that the global warming will release lots of methane contained in the permafrost and that will create a snowball reaction as methane is much more of a greenhouse effect gas than carbon dioxide. I can’t comment that because I don’t know enough about it. But in general thermodynamic, a system is stable or unstable. If unstable, a tiny change in the balance creates that said snowball reaction. But, surely, the earth has already been in many various cycles of different carbon dioxide in the past, hasn’t it? And the apocalypse hasn’t happened yet, as far as I know: we are still here. It doesn’t mean we shouldn’t b
