New York Times : Carbon dioxide makes up only 0.04% of Earth’s atmosphere. According to a panel convened by the American Physical Society, the low concentration is the main reason technologies for capturing atmospheric carbon dioxide are unlikely to succeed as a means of forestalling climate change. At an estimated $600 per ton, the cost of removing carbon dioxide from the atmosphere is too high to be practical. Although removing a ton of carbon dioxide from the exhaust chimneys of coal-fired power plants is less expensive, wide-scale implementation of carbon capture at power plants would still require government action to offset the cost.
