This diagram is from a video of a speech by Prof. Guy MacPherson of the U. of Arizona. Unless you are illiterate, or in denial, or in a “positive” state of oblivious bliss, this diagram alone should knock your socks off. But even it represents understatements in every case, because the methane feedback loop was not factored into the computations.

In short, the phytoplankton in the ocean, which supports the entire marine food pyramid as well as regenerate 50% of the world’s oxygen supply, cannot withstand a 4 degrees Celsius temperature rise, due to both the heat and the acidity. The plants on land, responsible for the other 50%, likewise, though somewhat less so. Above a 4C temperature rise, life on Earth will by and large be extinguished.

Even without factoring in the methane feedback loop, the latest linear estimate still pegs +4C within 3 decades. With it factored in, one latest estimate pins +4C within one decade. Good bye children, good bye biosphere, Good bye world-as-we-know-it.

Prof. MacPherson’s speech does end on a “positive” note of sorts, what I have touched upon in an earlier blog of mine, that the coming Global Economic Collapse will slow down the Global Ecological Collapse a little, by drastically reducing the human population, halting fossil fuels combustion, terminating the planet-destroying status quo, and buying our children a little time to seek a solution to Runaway Global Heating.

Keep your heads in the sand if it will keep you happy, bash “doomsday prophets” again if it will make you feel superior, but for those truly concerned about life on Earth and our children’s future, this video is a must.
