Most Dangerous Uses and Biggest Misuse of Water
Posted on Apr 30, 2010 by Zachary Shahan.
Robert Glennon is the author of Unquenchable: America’s Water Crisis and What To Do About It. I’m sure the whole book is a good read, but for a snapshot of some of the biggest water issues we face today, here are some of Glennon’s thoughts supplemented with a little additional research of my own.

How Much Clean Water is Available for Human Use?
Posted on Apr 01, 2010 by Zachary Shahan.
We know that the world is covered in water. Continents are like large islands in the planet’s much more expansive oceans. 75% of the Earth is covered in water. Yet access to clean, fresh drinking water is a major world concern. An infograph I ran across on world water day helps to show, in a simple format, why this is the case.

Australia’s 40 Year Drought Linked to Antarctica’s Heaviest Snowfall in 38,000 Years
Posted on Feb 10, 2010 by Susan Kraemer.
The drought that has affected Western Australia since the 1960’s now appears to be linked in a new kind of “precipitation see-saw” effect with a correspondingly higher snowfall in East Antarctica during the same 40 years, according to two scientists who just published the findings in the journal Nature Geoscience this weekend.

NASA Grace Satellites Track Groundwater Levels from Space
Posted on Dec 23, 2009 by Scott James.
NASA satellites are returning some disturbing news about the state of the earth’s groundwater. Two GRACE (Gravity Recovery and Climate Experiment) satellites are reporting data based on small monthly changes in Earth’s gravity field that are chiefly caused by water movement across the Earth’s water stores. The two GRACE satellites are the only satellites capable of monitoring deep stores of water in the earth.

Overpopulation to Blame for Southeastern U.S. Water Shortages
Posted on Oct 21, 2009 by Derek Markham.
Water shortages in the southeastern U.S. during the last two years were due to the skyrocketing population growth in the area, not just the drought, says a new study from Columbia University researchers. Some state’s populations, such as Georgia’s, jumped almost 50% in only 17 years, putting pressure on local water supplies and increasing the effect of drought in the region.
