The ascendancy of Donald Trump to the presidency, the selection of his cabinet and senior advisers, and the actions of the GOP-dominated legislative branch have all raised new serious questions and concerns about the role of science, research, and analysis in national law and policy. These concerns…

Geologic time scales are long – far too long for the human mind to easily comprehend. Over millions, and tens of millions, and hundreds of millions of years, the Earth has changed…

There is strong bipartisan support for expanding investment in the nation’s water infrastructure as part of a broader infrastructure effort. But…
In late February 2017, the Pontifical Academy of Sciences hosted a workshop on the human right to water organized by the Cátedra del Diálogo y la Cultura del Encuentro of Argentina with several other organizations. With many colleagues from science, law, human rights, history, and religion, this…
National academies of sciences from around the world have published formal statements and declarations acknowledging the state of climate science, the fact that climate is changing, the compelling evidence that humans are responsible, and the need to debate and implement strategies to reduce…
(Updated January 2017 by Dr. Peter Gleick, Pacific Institute)
Scientific understanding of the role of humans in influencing and altering the global climate has been evolving for over a century. That understanding is now extremely advanced, combining hundreds of years of observations of many…
Among the different professional categories, scientists and engineers remain very highly respected by the public, at least compared to politicians, business leaders, the media, and even religious authorities. Part of this is due to the fact that success in the scientific enterprise depends on…
My new Science Magazine article “Water Strategies for the Next Administration” has just been released (embargo lifts 11am Pacific, November 3rd; the print version will appear in the November 4th issue of Science). It identifies six major water-related challenges facing the United States and offers…

The announcement that Pacific Gas and Electric (PG&E) will close the Diablo Canyon Nuclear Plant when its current operating licenses expire in 2025 has caused what can only be described as consternation mixed with occasional conniptions…
Populations around the world face many severe water challenges, from scarcity to contamination, from political or violent conflict to economic disruption. As populations and economies grow, peak water pressures on existing renewable water resources also tend to grow up to the point that natural…
As readers of this column may already know, earlier this week the Pacific Institute and I announced an important and exciting change: on July 1st after 28 years as co-founder and President of the Institute, I will be moving to a new position as President Emeritus and Chief Scientist. A wide…
Since its founding in 1987, the Pacific Institute has worked to understand the links between water resources, environmental issues, and international security and conflict. This has included early analytical assessments (such as a 1987 Ambio paper and this one from the journal Climatic Change…

Water was a Top Risk on the 2015 Global Agenda
In early 2015, participants at the World Economic Forum, a who’s who of the political and business elite, ranked water crises as the top global risk. Water was also a key factor in the adoption by the…
On December 9th, National Public Radio broadcast an interview between NPR’s Steve Inskeep and Senator Ted Cruz on the subject of climate change. Below is an annotated transcript of that interview with my [bracketed] responses to the consistently false scientific claims made by Senator Cruz.…

The recent severe drought in the Western United States -- and California in particular -- has shined a spotlight on a range of water-management practices that are outdated, unsustainable, or inappropriate for a modern 21st century water system. Unless these bad…

Last week, the Pacific Institute published the first comprehensive analysis of the impacts of the drought on California crop revenue and agricultural employment through 2014. The study showed that during the recent drought California’s agriculture…

California is in a severe drought – four years long now. But what does the drought really mean for the things we care about: food production, fisheries, industrial activities, rural communities? As part of the work of the Pacific Institute to evaluate both the…

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…
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…
[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’s hottest and driest drought in recorded history has shifted the sources of electricity with adverse economic and environmental consequences. The Pacific Institute has just completed and released a report that evaluates how diminished river flows have resulted in less hydroelectricity,…
If there is anything that the past few decades of research and study of major global challenges tells us, it is that truly effective solutions to sustainability challenges require truly integrated approaches across disciplines, fields of study, data sets, and institutions. We are not going…

1. The California Drought Becomes an Emergency
California’s multi-year drought grew dire enough in 2014 to prompt Governor Jerry Brown to declare a drought emergency in January. By the end of the year, California had…
The California drought continues.
While we do not know yet what the rest of the wet season will bring – and while we hope for the major storms needed to recharge our rivers, groundwater and reservoirs – it seems increasingly likely that California will not see enough precipitation to get out of the…
Over the past three years (and indeed, for 10 of the past 14 years) California has experienced a particularly deep drought. How bad is the drought? Is it the worst in the instrumental record? The worst in over a century? The worst in 1200 years? The worst “ever”? And why has it been so bad?
There…

New monthly water use data for California water utilities shows that residential water use varies widely around the state, and that the response to the drought has been uneven. Moreover, in some areas, residential use averages more…
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 just…
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…
As input to the ongoing discussions about how to meet and overcome the spreading risks of Ebola, here are some summary thoughts about the water-related components of U.S. efforts. Specifics about the operations and effectiveness of water treatment or supply technologies, or the medical and health…
