We are the Guardians of the Future

We are facing the prospect of losing much, if not all, of the progress which has been made to preserve our planet. The current adminsitration has vowed abandoned the United Nation's Paris Agreement on climate change, is working to increase coal production, to dismantle the Environmental Protection Agency - basically deplete and destroy our natural world for the benefit of money, jobs, and industry. Now, more than ever, we must remain vigilant and very active in our work as guardians of the future.

Mothers for Peace argues for closure of Diablo Canyon in 2019

On Friday, January 27, Mothers for Peace through Ojai-based attorney Sabrina Venskus, submitted expert testimony to the California Public Utilities Commission showing that Diablo Canyon should be closed in 2019, not 2024. news release The hearings took place in April.

One of Mothers for Peace's expert witness, nuclear engineer Arnie Gundersen, chief engineer for Fairewinds Associates, Inc, provided testimony demonstrating unsafe and unreliable conditions at the plant.  Arnie Gundersen testimony

Another expert witness is David D. Jackson who works with the Department of Earth, Planetary, and Space Sciences at UCLA.  In his testimony, Dr. Jackson explains the many types of seismic damage to the plant in case of an earthquake. Among his assertions is that the substantial risk of earthquakes at Diablo Canyon nuclear plant has been underestimated, and that the seismic studies relied upon evaluate only a part of the risk which affects any decision of how long to continue operation of the two Diablo Canyon reactors.  David D. Jackson testimony

Mothers for Peace are cosponsoring the testimony of Women's Energy Matters. Robert Freehling is an expert in renewable energy and shows that needed replacement energy can be supplied by renewable resources long before PG&E's proposed closure date of 2025. Robert Freehling testimony

Mothers for Peace is cosponsporing Part V of the testimony of  the Alliance for Nuclear Responsibility. This section opposes PG&E's request that the CPUC allow the corporation to charge the rate-payers $52.7 million to reimburse PG&E for the funds it spent on license renewal between 2009 - 2016, before it offered to shut down the two Diablo reactors. A4NR testimony

and the pollution continues

The Japanese government is attempting to minimize the extent of the contamination. It is set to lift evacuation orders and force the refugees back into highly contaminated areas.

Sign this Greenpeace petition and put pressure on the Japanese government to treat these Fukushima survivors fairly.


The idea that nuclear power is the solution to climate change is a SMOKESCREEN.
