The concept of 'CLOSING A FEEDBACK LOOP'  means that a loop is closed to affect the person or agents that originally are  responsible for an action so that they plainly feel its effects. This almost inevitable leads to corrective action. One of the reasons why climate change does not  arouse passion and action is that it is largely invisible and most people are not aware of it, although extreme weather events are beginning to change this somewhat. The schematic representation shows how systems thinking might help to draw attention to such situations by graphically connecting the dots to promote understand and hopefully action when people realize that there is a price to be paid for inaction.  Please note, however, that the loop does not describe dynamic behaviour in the normal system dynamics sense. 

Capitalism is in crisis and climate change disruption is now beginning to hit the bottom line. Insurance companies know this well. According to a report by the Bank of England, insured losses have risen from $10 000 million in 1985 to $50 000 million in 2015. Climate change cannot be reversed, and extreme weather events  will undoubtedly get worse in the future strengthening the disruptive effects shown in the CLD.  Another dynamic is that companies will continue to automate and, as The Economic Policy Institute has shown, fail to reflect  productivity gains in workers' salaries. The result, stagnating salaries is disastrous for demand, given that capitalism needs endlessly rising demand and consumption. A further serious problem is that as climate change gets worse there will be increasing demands for companies to assume their responsibility and bear the costs of negative externalities.  The CLD shows these factors which are likely to lead to the collapse of the system: when capitalism can no longer generate 'capital' it has stopped to serves any useful purpose.

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!

The 3-machines energy transition model is a global system dynamics model based on energy balances,  and used to explore the energy frontiers for stabilizing the Earth's climate. The model comprises a hypothetical fossil engine, a solar engine including energy storage, and a carbon scrubber. These machines interact with Earth's carbon cycle and satisfy humanity’s energy demand. A detailed description can be accessed here: https://osf.io/fcwt8/

Pope Francis, in his recent encyclical on climate change, said that social movements are critical in promoting action on global warming. This simple CLD shows how the influence of climate-change movements could affect both public opinion and the government. An important aspect is that the activism of such movements will have a negative influence on the prestige of the fossil-fuel companies. This in turn will weaken their capacity to influence and to exert pressure on the government.  As the movements act, pressure on the government will increase but simultaneously the capacity of the fossil fuel industry to pressure  the government will decrease. As a result, the government will find it easier to push trough legislation to force fossil fuel companies to keep unburnable reserves in the ground. Climate change moments can contribute decisively to bring about urgently needed action on global warming
