During its more than five-month stint on Mars last year, NASA's Phoenix Mars Lander found evidence that liquid water existed at the spacecraft's landing site, some Phoenix team members say.

Water is key to all forms of life as we know it and the discovery of liquid water would suggest a greater opportunity for biology on the red planet.

The new but controversial conclusion comes from observ ... read more >>

As the specter of climate change looms ever closer, it has become more likely that Southern Nevada municipalities will have to fight for their lives — and those fights will be over water. Municipal and regional water managers are recruiting an army of lawyers and preparing to go to war for resources. At stake is the West’s main water supply — a sum of water that most climate models expect to shri ... read more >>

A YouTube video uploaded by the University of Arizona about how to manage stormwater in an arid climate. The video is a bit long, but packed with lots of interesting information. Managing for flash floods, etc. isn't always what comes to mind when we think of municipal water design. The video reviews strategies to control erosion and other flash flood water situations. - From "Stormwater Mana ... read more >>

The U.S. Senate is starting to look harder at the nexus between energy and water. Tomorrow, the Senate Energy and Natural Resources Committee will hold a hearing on a bill introduced last week that would direct the Department of Energy to develop a roadmap for addressing the linkages between energy and water. The relationship between the two sources has been a growing concern among energy and wat ... read more >>

More bad news on climate change is expected as more than 2,000 climate scientists gather in Copenhagen. They will be trying to pull together the latest research on global warming ahead of political negotiations later in the year. The scientists are concerned that the 2007 reports of the Intergovernmental Panel on Climate Change (IPCC) are already out of date. Their data suggests greater rises ... read more >>

The Earth may be two-thirds water, but only about 1 percent of that water is actually usable for human consumption and agriculture. What’s more, as the planet warms and the population shifts, even that 1 percent is at risk. That is why demand for hydrologists has been predicted to grow 24 percent from 2006 to 2016, much faster than the average for all occupations, according to the Bureau of Labor ... read more >>

It is China's latest grand attempt to tame nature. Three canals will bring water hundreds of miles to Beijing and other thirsty cities in the north. More than 350,000 people in the way will be forced to move.

For many in Zhangyigang, a village of 942 people in brick and mud houses in central China, it will be their second uprooting. They moved to higher ground in the late 1950s and 1960s when ... read more >>

Global warming doesn't just mean there will be new patterns of mass migration, wars and border lawlessness in the 21st century. For the great climate change isn't affecting just the warmest parts of the world; it's also affecting areas that used to be the coldest.

The great Arctic Ocean polar ice cap is already melting. The Arctic Ocean could be navigable year-round within decades. The rate of ... read more >>
