Let's assume Washington isn't passing sweeping climate change legislation in the near future. What should or could we do to alter the emissions of greenhouse gases? We can make big impacts by using energy efficient technologies and buying renewable energy.
Nature is a powerful tool right at our fingertips offering tangible results. Conserving our natural resources gets to the root of the problem. If we reduce carbon pollution, we will reduce the increasing impacts of climate change.
We wouldn't be having this conversation if the president had his druthers: nearly everyone agrees with Professor Posner that it would be much better if Congress put a carbon-control law on the books. But it looks like polar bears will be sipping piña coladas before that happens.
