Extinction Events and Hydrogen Sulfide

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

Who is James G. Anderson and What Does He Know About Climate Change?

  Recently, I had an opportunity to repost a video which I viewed several years ago from Harvard Professor James G. Anderson regarding climate change. I have actually watched the video two or three times in the past, but there are certain parts that have now become more interesting as time has moved forward.  In the video, Anderson reveals why the term "global warming" is very inappropriate and doesn't accurately describe what is really happening. Then he describes what will happen as times moves forward with warmth and moisture entering the stratosphere as a result of climate change - as ice continues being removed from both poles, eventually the temperature difference between the tropics and the poles will disappear. This is a hugely important distinction, as the global climate system today utterly depends on those temperature differences for the way it behaves. I will go into more detail regarding this phenomenon in my next article and how it will affect the planet

Relocating due to Sea Level Rise

Naples Beach and Pier, Florida It really requires some true grit to begin making the determination that one needs to move to avoid serious consequences from any particular predicament; and the older one is, the more difficult it is to leave a loved area. Almost no area will be left untouched by climate change and all the other predicaments caused by ecological overshoot, but one predicament in particular, Sea Level Rise (SLR), brings forth a whole host of issues that many don't know about. Sadly, I had the experience of attempting to explain this to a friend who got mad at me for posting scientific articles regarding the situation. Many people are suffering from denial of reality  surrounding these issues, which doesn't help. Overwhelmingly, the easiest issue that almost everyone can see is street flooding caused by high tides (sunny day flooding). This makes the situation impossible to ignore, and building streets higher doesn't resolve the issue of water coming UNDERNEAT
