The 20th century saw unprecedented gains in global welfare. The global economic system generated 1.5 trillion tonnes of CO2 emissions.
It is now clear: business as usual will cause climate catastrophe with the potential to wipe out a century of progress.
Imagine what the world would look like 50 years from now: climate change, deforestation, desertification, water shortages, etc.
There are metaphorical elements of “Mad Max” that are already happening, and that will only worsen with time.
Our climate models certainly predict increasing desertification, that are on the boundary between wet and dry.
