DRAFT conceptual model of climate change connections in Yamuna river project.

A very simple thermodynamic model of a planet, which includes first order approximations of its radiation balance (black bodies), including two radiation modulating effects i.e. albedo and green house and two heat storages (ocean and atmosphere). It is a lumped model which does not consider spatial variations and resulting mass transports - thus no heat exchange between e.g. equatorial and polar regions...
As a consequence all values are surface specific i.e. per square meter. E.g. the energy balance is the  balance in  W/m² and the heat reservoirs are water and air columns with a cross section of 1 m²...

Social movements have a major role to play in forcing politicians to act on climate change. This opinion has been clearly expressed by Pope Francis in his encyclical on climate change and, amongst others, also by Naomi Klein in her book 'This changes Everything'. The CLD suggests the need to strengthen the reinforcing loops R1 and R2 representing the activities of  environmental movements and also to disrupt the reinforcing loop R3 representing climate change  deniers. The most effective way in my opinion  to strengthen R1 and R2 is to weaken R3. This could be done by countering false arguments by pointing out on all occasions that the debate on climate change is over: climate scientists, by an overwhelming consensus, have established that anthropogenic global warming is a scientific fact. It could also be done by educating the public. The urgency of the situation suggests that the most effective way of doing this could be by closing negative feedback loops, for example, by linking extreme weather events, supported by graphic images, to global warming. Global warming can also be linked to inequality, poverty, larger forest fires,  coral reef bleaching, etc. The Pope has started the work by establishing these links in his encyclical. Of course, these are merely suggestions. Looking at the CLD carefully might well reveal other effective points of intervention
