Article in June 29 New Yorker by Elizabeth Kolbert on scientist James Hansen’s conclusion that the threat of global warming is far greater than expected. Quotes from the New Yorker abstract:
• What is now happening, Hansen said, is carbon dioxide is being pumped into the air some ten thousand times faster than natural weathering processes can remove it.
• Hansen argues that the only way we can constrain the amount of carbon dioxide in the atmosphere is to drastically decrease the use of coal.
• In order to stabilize carbon dioxide levels in the atmosphere, annual emissions around the globe would have to be cut by something on the order of three-quarters. So far, there’s no evidence that anyone is willing to take the necessary steps.
