Global climate change and overpopulation are combining to threaten fresh water supplies. To avert vast shortages, scientists are trying new ways to desalt seawater to bring clean drinking supplies to communities all over the world.

While desalination technologies are advancing they still remain cost prohibitive. A number of methods now exist to purify saltwater that include solar power and fossil fuels. But nuclear energy might be a more efficient method of removing contamination and saltwater because it can do so efficiently and on a large-scale basis without adding to concerns over global warming.

Water resources across the Southeast are being re-evaluated as an historic drought reigns over the region. Because utilities use more fresh water than any other entity, they are coming under increasing scrutiny.

The problem is that droughts across the United States have decreased the pool of water now available to all concerns. Not only do utilities use it. So does big industry and small residential households. To compound the matter, the demand for electricity in this country is expected to rise by 2 percent a year over 20 years. Governments and businesses alike are now calling for concerted conservation efforts. Another approach being pushed is the development of new utility technologies that require less water.

Almost everyone is familiar with "Kyoto." But in due time, the name "Bali" will eclipse that 1997 global warming pact. While the Kyoto Protocol set the stage to curb greenhouse gas emissions through 2012, the next phase of negotiations will carry on until 2050. The initial discussions will begin this December in Bali, India.

The United Nations has set the stage, having just released its findings on climate change. The study, written by more than 2,500 scientists from around the globe who were appointed by their respective governments, is definitive in its determination that humans are causing rising temperatures that could lead to environmental devastation. It lays the blame on excessive use of fossil fuels by power plants and major industry.

Thursday's traditional Thanksgiving Day football game in Detroit will be the first carbon-neutral contest in National Football League history.

Ford Field and the Detroit Lions announced Monday that they will offset greenhouse gas and carbon dioxide emissions for the Lions' 68th annual Turkey Day game.

The organizations will purchase offsets through Detroit-based Carbon Credit Environmental Services.

It's been more than a year. But, California's passage of the nation's first global warming law is still being defined. And, it will continue to evolve in the coming years as the state grapples with how to cut its greenhouse gas emissions.

The law there, which took effect on Jan. 1, 2007, sets out to reduce California's heat-trapping pollutants to 1990 levels by 2020. The state is off to a notable start by enacting rules to increase its renewable energy supply to 33 percent by 2020 as well as by creating new energy efficiency performance standards and cleaning up motor vehicle emissions.
