Global Warming, Carbon And Mangrove Expansion


How nature is responding to climate change. "Much of the Florida shoreline was once too cold for the tropical trees called mangroves, but the plants are now spreading northward at a rapid clip, scientists reported Monday. That finding is the latest indication that global warming, though still in its early stages, is already leading to ecological changes so large they can be seen from space...In both the beetle and mangrove cases, scientists have found that it is not the small rise in average temperatures that matters, nor the increase in heat waves. Rather, it is the disappearance of bitter winter nights that once controlled the growth of cold-sensitive organisms." Justin Gillis in The New York Times.

The social cost of carbon is a real thing, the Department of Energy says. "The Obama administration says it will not reconsider a new carbon emissions formula for federal regulations. The conservative group Landmark Legal Foundation filed a petition in August calling on the Department of Energy (DOE) to strike the provision on the "social cost of carbon" from a microwave efficiency rule...Reconsidering the rule would not change the standard adopted for microwave ovens, the department said in an early copy of its response that will be published Tuesday. The social cost of carbon directive, which was updated in June by the Office of Management and Budget, bumped the cost of carbon to $35 per metric ton from $21. The new formula will dramatically increase the projected benefits of regulations that clamp down on air pollution and greenhouse gas emissions." Laura Barron-Lopez in The Hill.
