Washington to be sued over global warming

In a landmark judgment, a court in California has allowed a coalition of environmental groups to sue the US government over global warming - the first time a court has recognised the potentially disastrous impact of climate change.
A judge in San Francisco gave permission for the two groups, along with four US cities, to sue two federal development agencies that provide billions of dollars in loans to fund projects overseas. Some of the projects are power plants that emit greenhouse gases while others include pipeline projects that allow the transfer of oil.
