The coal industry is an even larger part of the Australian economy than it is of the American, and it has an enormous amount of political power.

• In the U.S. alone, weather disasters caused $50 billion in economic damages in 2010.
• Extracting oil from the tar sands is a nasty, polluting, energy-intensive business.
• Bill Gates is a relative newcomer to the fight against global warming, but he's already shifting the debate over climate change.

• Geoengineering - the deliberate, large-scale manipulation of the earth's climate to offset global warming - is a nightmare fix for climate change.
• "If you are interested enough in the climate crisis to read this post, you probably know that 2 degrees Centigrade of warming (or 3.6 degrees Fahrenheit) is the widely acknowledged threshold for ""dangerous"" climate change."
• Climate change is a global issue - from the point of view of the Earth's climate, a molecule of CO2 emitted in Bejing is the same as a molecule emitted in Sydney.
