A dire picture of the Earth's health is painted in the State of the Climate report, a peer-reviewed 300-page tome that comes out once a year and is compiled by 450 scientists from around the world.

Dutch environmentalists said Tuesday they are suing the government over poor air quality, saying people's "fundamental" rights to good health were being infringed.
