Clone of Accelerated Global Warming

Rakesh Kotla
There is now substantial evidence that three unstoppable reinforcing feedback systems that can only accelerate global warming have been triggered in the Arctic. R2 illustrates a process whereby frozen methane hydrate,  which exists in enormous quantities on the seabed of the shallow Arctic Ocean shelf, is breaking up as the ocean warms. This leads to methane gas, a greenhouse gas about 20 times more powerful than C02, bubbling up to the surface. R1 shows that as the ice cover of the ocean melts and shrinks, less sunlight is reflected back into space and more is absorbed by  the ocean, warming it as a consequence. The warmer ocean water and warmer air temperature will then melt more ice, but it will also break up more methane hydrates.   R3 describes a similar process where melting permafrost releases methane into the atmosphere, making the situation even worse. These processes are multiplicative, they reinforce each other.  Below are links to three articles that provide  evidence that this is going on now. Systems thinking tells us about reinforcing feedback loops and the associated exponential growth. Taking this and the evidence provided by the articles into account the conclusion clearly points to increasing and accelerated global warming. The recent Paris agreement on global warming may have come too late!

A very simple thermodynamic model of a planet, which includes first order approximations of its radiation balance (black bodies), including two radiations modulating effects i.e. albedo and green house and uses two heat storages (ocean and atmosphere). It is a lumped model which does not consider spatial variations thus e.g. no heat exchange between equatorial and polar regions (lateral).
