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
Clone of CLIMATE CHANGE INERTIA
A model of Global Climate Change driven by the impact of Carbon Dioxide on the Greenhouse Effect. This model contains a physical model of energy inflows ☀️ and outflows from the Earth (primary source). And a simple model of carbon dioxide sources and sinks in the atmosphere (primary source).
The energy model assumes inflowing short-wave solar radiation that does not interact with the atmosphere. A fraction of this is reflected immediately (e.g. by snow and ice cover). The remaining is absorbed 🌎 and re-radiated as long-wave infrared which can be captured by the atmosphere ☁️. The fraction captured by the atmosphere is related to the level of Carbon Dioxide in the atmosphere.
This model tracks Carbon Dioxide emissions from burning fossil fuels 🏭 and land use changes 🚜 (e.g. deforestation). It also tracks removal of Carbon Dioxide from the atmosphere into a land sink 🌲 (e.g. vegetation) and the an ocean sink 🏖.
🧪 Experiment with different levels of emissions to see their impact on global average temperatures. You can also compare predicted temperatures and Carbon Dioxide levels to historical data.
