Federal law requires comprehensive reports on global warming every four years. Last year a lawsuit forced the Bush Administration to issue its first such document since it took office in 2001. Yesterday, the Obama White House updated that draft report with stronger language and ten "key findings." The report comprises dire warnings from thirteen federal agencies about the increasing impact of global warming. It's already changing ocean levels and weather patterns in the United States, with dramatic effects on water supplies, agriculture and human health. The report comes as Congress tackles a massive energy bill designed by supporters to slow and reduce the consequences of climate change. Is it too complex and expensive or too little to late? Will Republicans — and Democrats — water it down?
