Public health officials are working to contain a persistent outbreak of tuberculosis affecting L.A.’s homeless population.

They want to get a handle on the crisis as quickly as possible, becasue tuberculosis can be deadly if left untreated.

Right now, it’s primarily affecting the homeless population in downtown L.A., and officials have seen the trend continue in the Los Angeles area.

Mounting scientific evidence indicates climate change will lead to more frequent and intense extreme weather that affects larger areas and lasts longer. We can reduce the risk of weather-related disasters, however, with a variety of measures. Experts say that a good strategy should include a variety of actions such as communicating risk and transferring it through vehicles such as insurance, taking a multi-hazard management approach, linking local and global management, and taking an iterative approach as opposed to starting with a master plan.

Nearly two years after a powerful earthquake triggered a leak at Japan's Fukushima Dai-ichi nuclear plant, the effects of that disaster are still being felt on the other side of the planet.

A report released earlier this month by researchers at Stanford University's Hopkins Marine Station found that bluefin tuna caught just off the California coast tested positive for radiation stemming from the incident.

The study looked at the levels of radiocesium, one of the most common results of nuclear fission reactions, in Pacific Bluefun Tuna--largely as way to track the species' migratory patterns as the fish make their cross-oceanic journey in search of prey.

According to the July 2011 census, more than thirty-seven million people live in the state of California, increasing the pressure on the state’s water sources. Desalinating sea water as a solution to the scarcity of fresh water is not a new technology — it has been around for more than four decades — but it has more recently been considered as a way to address California’s chronic, and growing, water shortage.

The Seattle Times reports that the idea has run into problems, and rising construction costs, energy requirements for running desalination plants, and legal challenges have limited desalination in California to only one plant producing drinking water.

NRC officials give their first public account of their probe into the shuttered plant's problems.

Faulty computer modeling caused the equipment problems that are expected to keep the San Onofre nuclear plant dark through the summer, federal regulators said Monday.

Officials from the U.S. Nuclear Regulatory Commission gave their first public account of the initial findings of their investigation into the plant's problems at a meeting in San Juan Capistrano.

What they did not give was any indication of how long the plant is likely to remain out of service, saying there are still questions plant operator Southern California Edison needs to answer and more inspections the NRC must do.

Groundwater depletion has been most severe in the purple areas indicated on these maps of (A) the High Plains and (B) California's Central Valley. These heavily affected areas are concentrated in parts of the Texas Panhandle, western Kansas, and the Tulare Basin in California's Central Valley. Changes in groundwater levels in (A) are adapted from a 2009 report by the U.S. Geological Survey and in (B) from a 1989 report by the USGS.

The U.S. food supply may be vulnerable to rapid groundwater depletion from irrigated agriculture; for example, from 2006 to 2009, farmers in the south of California’s Central Valley depleted enough groundwater to fill the U.S. largest man-made reservoir, Lake Mead near Las Vegas — a level of groundwater depletion that is unsustainable at current recharge rates

Threats to California's water system must be addressed now in order for the state's economy to grow and prosper, according to a report by the Public Policy Institute of California released late Wednesday.

The continued expansion of water management tools, such as the reuse of highly treated wastewater, underground storage and water "banking," will allow California to manage future water shortages, the report concludes.

The report represents a consensus view of a wide-ranging group of experts on the role of water in the state's economy.

U.S. seismologists currently testing new warning system

by Andrew Pinsent - CBC News - May 5, 2012

Scientists in the United States have been testing an advanced tsunami warning system using GPS data, combined with traditional seismology networks, to attempt to detect the magnitude of an earthquake faster so warnings of potential tsunamis can get out to potentially affected areas sooner.

The prototype is called California Integrated Seismic Network (CISN), and is a collaboration between the United States Geological Survey (USGS) and The Gordon and Betty Moore Foundation, whose focus is on environmental conservation.

Researchers place a model hospital on a shake table to assess the structure’s ability to withstand earthquake; in accordance with California latest building code, base isolators, which are rubber bearings intended to absorb the shock of the motion, were installed underneath the structure; the hospital passed the 6.7-magnitude and 8.8-magnitude tests with flying colors.

Last Tuesday, engineers from the University of California, San Diego conducted an ambitious and successful earthquake simulation, with what some called “boring” results.

Engineered had constructed a 5-story building, complete with a hospital operating room, an elevator, a kitchen filled with glassware. They also added a heavy air-conditioning unit to the roof. The building, built to California’s top earthquake codes, was then placed on top of a shake table, a device for shaking structural models or building components with a wide range of simulated ground motions, including reproductions of recorded earthquake time-histories.

The power plant has been shut down since this winter, when a small amount of radioactive gas escaped.

• Anti-nuclear activists warn of a potential environmental catastrophe
• The San Onofre nuclear plant has been shut down since radioactive gas escaped
• Officials have said there's no harm to the public health, but can't identify problem's cause
• The head of the NRC says the plant won't restart until a cause and plan is put forward

(CNN) -- A large Southern California nuclear plant is out of commission indefinitely, and will remain so until there is an understanding of what caused problems at two of its generators and an effective plan to address the issues, the nation's top nuclear regulator said Friday.

California's Bay-Delta water supply area // Source: usgs.gov

Homeland Security News Wire - March 30, 2012

Simultaneously attaining a reliable water supply for California and protecting and rehabilitating its Bay-Delta ecosystem cannot be realized until better planning can identify how trade-offs between these two goals will be managed when water is limited, says a new report from the National Research Council.  Recent efforts have been ineffective in meeting these goals because management is distributed among many agencies and organizations, which hinders development and implementation of an integrated, comprehensive plan.  Additionally, it is impossible to restore the delta habitat to its pre-disturbance state because of the extensive physical and ecological changes that have already taken place and are still occurring, including those due to multiple environmental stressors.

The state spends a fraction of what countries like Mexico and Japan spend on their systems. One reason for the lack of interest, experts say, is that California has not experienced a catastrophic quake in more than a century.

First, there is great value in a systems approach as a heuristic for understanding interlocked social-ecological-technological processes, and in analysis across multiple scales. Yet we need to move beyond both systems as portrayed in resilience thinking, and the focus on actors in work on vulnerability, to analyse networks and relationships, as well as to attend to the diverse framings, narratives, imaginations and discourses that different actors bring to bear.

There are many definitions of resilience from simple deterministic views of resilience anchored in Newtonian mechanics to far more dynamic views of resilience from a systems perspective, including insights from quantum mechanics and the sciences of complexity.  One baseline perspective of resilience sees it in terms of the viability of socio-ecological systems as the foundation for sustainability.  For those that are ready to look beyond resilience as the ability to return to the "normal state" before a disaster, take a look at:
