by Peter Gleick and Heather Cooley Debates about water in California, the western U.S., and indeed, worldwide, have traditionally focused on the question of how best to further expand water supply to meet some hypothetical future increase in water demand. And the solution frequently offered is to build massive new infrastructure in the form of…

It’s only natural that during a crisis we look to single, “silver bullet” technical solutions, after all, they are supposed to be effective against werewolves, witches, and other monsters. For monsters like the ongoing severe California drought, the current favorite silver bullet is seawater desalination.  And why not? California sits at the edge of the…

[As part of the Pacific Institute’s ongoing efforts to evaluate the impacts of the California drought and offer strategies, technologies, and policies to reduce those impacts, we are presenting a series of short assessments on “Understanding the Numbers.” This piece is the part of that series.] California is a wonderful place to grow food. The…

The most important trend in the use of water is the slowly unfolding story of peak water in the United States and elsewhere. Data on US water use are compiled every five years by the US Geological Survey, covering every state and every sector of the economy. The latest data – for 2010 – have…

In a new study just published by the journal Sustainability Science (Springer), analysis from the Pacific Institute (with lead author Dr. Juliet Christian-Smith, now at the Union of Concerned Scientists) shows that many of the fundamental responses of California water users to severe drought actually make the state’s overall water conditions worse – that in the end,…

In the past few weeks, I have had been asked the same question by reporters, friends, strangers, and even a colleague who posts regularly on this very ScienceBlogs site (the prolific and thoughtful Greg Laden): why, if the California drought is so bad, has the response been so tepid? There is no single answer to…

Snapshots from the New National Climate Assessment After three years of intensive effort, research, writing, and review by hundreds of climate scientists, the latest update of the U.S. National Climate Assessment was released today. It includes many long, carefully prepared sectoral and regional studies, and covers the massive range of effects of climate change on…

California, and much of the southwestern US, is in a severe drought. Again. And as appropriate, there is growing debate about what we, as citizens, communities, corporations, and governments should do to tackle water shortages and the bigger question of sustainable water policy. Suggestions range from the large-scale and comprehensive (build more dams, transfer more…

The end of the rainy season in California is arriving in a few weeks, and the April 1st snowpack measurement, which is a key indicator of water conditions, is tomorrow. As we approach the dry spring and summer months, the scope and severity of California’s drought will become more apparent, but it is already clear…

We’ve entered a new era: politicians can now talk loud and clear about the reality of human-induced climate change and the growing threats to humanity. With strong, unambiguous statements by President Barack Obama, Secretary of State John Kerry, Senator Sheldon Whitehouse, and a growing chorus of other top-level voices, the wholesale denial of climate science…
