What is hydrogen sulfide and what does it have to do with extinction events? In my last entry where I discussed James G. Anderson, I pointed out how the current behavior of the climate system will be interrupted and inherently changed by the loss of Arctic ice and the cryosphere in general. This loss of ice in sea ice, permafrost, glaciers, and frozen lakes and rivers will dramatically speed up the process of warming not only in the Arctic, but the entire Northern Hemisphere and beyond. As it does this, eventually, the temperature difference between the poles and the tropics will disappear. Without the large temperature difference, winds will be diminished, causing the world's oceans to mix less. This will cause hypoxic conditions due to less circulation and less circulation will lead to stagnation, and general anaerobic conditions will lead to the production of hydrogen sulfide leading to sulfidic oceans, also known as the Canfield Ocean .  Understanding that the cryosphere  is
