Global warming is depleting fresh water and crops, destroying coral reefs and melting the Arctic, the United Nations said today in a report that concludes the world is ill-prepared to face many new threats.
Okay, fine. You're persuaded that climate change is a problem. So if we can work out the costs and benefits of reducing carbon emissions, we'll be able to decide on the cheapest course of action, right?
Something odd happens to the neighborhood around Marlins Park, Miami’s new $650 million baseball stadium, when you overlay 21st-century sea-level rise projections. It sinks below the waterline. It’s a shame. The park has a retractable, cloud-white roof to shield players and spectators from the summer sun. It recycles, sips energy and water, and is plugged into public transit. It has 27 flood gates, and was built one foot higher than floods are supposed to reach in once-in-500-year storms. The total, publicly financed package, with debt servicing, could cost Miami $2.4 billion by 2049. If the Atlantic inches in as projected, eventually it might not matter how many flood gates there are. Oceans are swelling as they absorb heat, and ice sheets in Greenland and Antarctica have been melting faster since the early 1990s. Sea-level rise estimates for later this century have been revised upward, to a global average of a foot and a half to three feet by 2100, without aggressive carbon-cutting, according to the Inter
China, the world’s biggest emitter of greenhouse gases, estimated the direct economic loss from rising sea levels and storm waves linked to climate change last year increased to the highest level since 2008.
