Dedicated to the balanced discussion of global warming
Financial Times Deutschland – May 15, 2007
Interesting article on the estimated costs of reversing the human induced effects of greenhouse gases that appear to be causing global warming. I would like to see some more data, specifically:
The world has until 2020 to reverse the trend of rising greenhouse gas emissions to avoid the most dangerous effects of climate change, the world’s top climate scientists have warned. Achieving this would reduce the world’s annual gross domestic product by 3 per cent in 2030, the UN expert panel concluded. Emissions have been rising for the past 150 years.
Cutting greenhouse gas emissions to the required level can be achieved with today’s technologies but bringing them into widespread use is likely to require extensive changes in public policy
Most of the technology needed to achieve the necessary cut in emissions is already commercially available, including nuclear power, renewable energy generation and measures that promote energy efficiency.
If emissions were to peak in 2015, which is viewed as unlikely to be achieved, and thereafter fall by about 50-80 per cent over the next several decades global warming would be limited to about 2° Celsius above pre-industrial levels, the IPCC report found. The world has already warmed by about 0.7°C in the past century. But if emissions continue to grow until 2030, which is widely viewed as more likely, temperatures would probably rise by 3°C above pre-industrial levels.
