The Noughties in Retrospect 2000-2010

Perhaps the biggest phenomenon from a western view has been the rise of China as a superpower.

Internet services and applications, terrorism and wars in the middle east, oil, global warming politics, are some of the big things as well.

What will 2010 see? Well, my bet is that energy will be a big part of it. Oil is limited and is getting more expensive, coal is not. But coal is bad in the global warming sense. The big coal powers USA, China, Germany, UK, Canada, Australia at least are probably just going to keep burning it and not care what it does to the rest of the world.

During the noughties, CO2 rose from about 365 to 385 ppm. If the decadal rate is constant at 20 ppm per decade, then 600 ppm, a doubling from 1950s levels will require 215 ppm more, or about 110 years. Of course, the decadal emissions rate is probably going to accelerate. Local climate change phenomena will come earlier than things like significant sea level rise but it’s harder to point out that greenhouse gases are responsible for them. A fascinating experiment, this atmosphere alteration.
