Den ursprungliga rapporten "Limits to growth" publicerades av den s.k. Rom-klubben för 40 år sedan. Nu kommer en uppdaterad rapport, som försöker göra sig en bild av situationen 2052.

En sammanfattning:

• While the process of adapting humanity to the planet’s limitations has started, the human response could be too slow.
• The current dominant global economies, particularly the United States, will stagnate. Brazil, Russia, India, South Africa and ten leading emerging economies (referred to as ‘BRISE’ in the Report) will progress.
• But there will still be 3 billion poor in 2052.
• China will be a success story, because of its ability to act.
• Global population will peak in 2042, because of falling fertility in urban areas
• Global GDP will grow much slower than expected, because of slower productivity growth in mature economies.
• CO2 concentrations in the atmosphere will continue to grow and cause +2°C in 2052; temperatures will reach +2.8°C in 2080, which may well trigger self-reinforcing climate change.
