This morning, the US. Supreme Court heard arguments from Earthjustice about why the Clean Water Act should not be interpreted to allow mining companies to dump mine wastes into our nation's streams, rivers and lakes. A mining company attorney told the court that an Alaskan lake would be better off in the long run after a mining company dumped its tailings into it, killing all the fish and most other life. Justice David Souter described that logic as "Orwellian." We will be blogging after the arguments are concluded. Read the entire transcript of today's Supreme Court hearing on the Clean Water Act.

In the arid West, water is life.  And life may get a lot more difficult for the Colorado River - a major source of water for Colorado, Utah, Arizona, Nevada and California - over the next few decades.

First, there's the double whammy of population growth and climate change, the first demanding more water from the river, and the second making it extremely likely that there will be less water for that population to drink, use to grow crops, etc.

Second, there's the threat from oil shale development.  The Bush administration pushed through midnight regulations last month to spur development of oil shale deposits in Colorado and Utah.  The Bureau of Land Management estimates that it will take three gallons of precious West Slope Colorado water to produce one gallon of fossil fuel.  And while no one in the world has yet figured out how to develop shale commercially, Shell - which is researching and investing in oil shale - has already bought large numbers of water rights in the Colorado River basin.  That has the water buffalos at the Denver Water Board worried.

With a single vote on Dec. 2, Florida took real leadership in the fight against global warming.

After years of head-in-the-sand policy making, this is a welcome change. We have Gov. Charlie Crist to thank: he proposed that Florida adopt clean car standards patterned after those in California.

And on Dec. 2, after six hours of public testimony, the panel that sets state pollution limits approved Florida's new clean car standards. The Environmental Regulation Commission's vote was a resounding 6-1, despite a considerable political push by automobile manufacturing lobbyists. Now, the proposal heads to the Florida Legislature in March, where the political battle begins anew.

We are thrilled to be living in this new, environmentally progressive Florida. Not only did the state reject a giant coal plant in the Everglades, but now leaders are actually supporting alternative energy and paying attention to cutting the global warming gasses spewing from millions of car tailpipes.

Smack in the middle of a groundwater shortage that had Southwest Florida officials begging people to use as little water as possible, agricultural operations opened their pumps wide and flooded millions of gallons of water wastefully over their fields.

They had legal permits to do this, permits issued by the Southwest Florida Water Management District, a taxpayer-funded water authority. We sued the water management district two years ago. On October 30, a Florida Appeals Court finally ruled in our favor.
