‘Earth’s Core Leaking’ Earth’s magnetic field, critical to all life, may be in danger from ‘leaking core’ By Desert Star Staff Scientists studying the earth’s core, vital to protecting us from dangerous highenergy particles from space, believe not only that it is leaking, but that it has been for about 2.5 billion years. While the cause of the leak remains unknown, as do the consequences for the Earth’s magnetic field,
scientists appear to have resolved the decades-old debate about whether the Earth’s core and mantle exchange material or not. The core is composed of iron and nickel, and with elements like platinum, gold, and tungsten. It reaches temperatures of 5,000 degrees Celsius (9,000 Fahrenheit) and many believe
it’s responsible for up to 50 percent of the volcanic heat released around the planet. The researchers, from French, Canadian, US and Australian universities, found newer mountains and rocks on the Earth’s surface featuring tungsten isotopes which are typically found in the outer core, but no farther up. As a result, the team posits that so-
called ‘mantle plumes’ brought core material to the surface. There was no evidence of leaks prior to this recent discovery. The implications of the research are still unclear. However, we know that the spinning solid part of the core is responsible for the Earth’s magnetosphere which helps protect us from the nastiest particles firing around space.
Scientists believe that the liquid part of the core is slowly solidifying and this latest research may provide unique insights into both the evolution of the Earth’s core as well as the origin of our allimportant magnetosphere. The research was published recently in GeochemicalPerspective Letters.
California’s New Roadmap to Tackle Uptick in Disaster By Desert Star Staff Sacramento – Six strategies stand to amplify whole community emergency preparedness and improve coordination of community assets for disaster response and recovery, describes a report released today by California Volunteers, Office of the Governor. In response to Gov. Gavin Newsom’s call to build community resiliency and ready the state for earthquake, wildfire, drought, and flood, the report developed in collaboration with Monitor Institute by Deloitte presents
solutions to leverage nonprofit, community-based, faithbased, and private-sector resources while working with the public sector. A roadmap offers investment strategies to effectively channel privatesector resources, spur cross-sector coordination, and bolster the capacity of local communities to strengthen resilience. “Gone are the days when we let a single “blue sky day” slip away because the next earthquake, wildfire, and other natural disaster is Continues on Page 6
