Given the failure of international climate negotiations, a tax on carbon consumption is the most effective way of lowering CO2 emissions. If nations are serious about addressing climate change, then they must pay for the carbon pollution caused by what they consume.
New York City had been gradually preparing for a world of rising seas and more powerful storms. But the devastation caused by Hurricane Sandy is now forcing officials to consider spending billions of dollars on storm protection, including a network of surge barriers.
