Could the 'Most Powerful Geothermal Reservoirs in the World' Save the Colorado River?
President Obama made a historic announcement Wednesday, saying that the federal government is considering investing in the geothermal power in the rock formations under the Salton Sea in Southern California. Considered to be "the most powerful geothermal reservoirs in the world," the Salton Sea announcement could play a critical role in the future management of the Colorado River.

Fifty years ago, Glen Canyon Dam was built above the Grand Canyon, and the Colorado River was enslaved to generate electricity to feed the hunger of the booming southwestern cities and suburbs. The Colorado's pulsing flows had carved and nourished the Grand Canyon for millennium, but that came to a crashing halt when the gates were closed and the water was ponded in Lake Powell. The environmental damage and steady decline of one of our nation's crown jewels has led to many calls for restoration of the natural system through the removal of Glen Canyon Dam.
The dam's ability to provide power has shielded it from any serious attempt to bring it down. Times change though and, over the last 16 years, the historic drought in the Southwest U.S. has drained Lake Powell to historic lows, severely diminishing the potential to generate hydroelectricity from the massive turbines encased in Glen Canyon Dam. Water and electricity managers are scrambling to come up with a plan to prop up the lake above what's called "power pool" so they can continue to generate and sell power. Any such solution is, however, clearly a stop-gap measure to keep the dam operational and is doomed to fail when confronted by the realities of climate change.
Fortunately, Obama's announcement offers a true path to the future.
The Salton Sea announcement could create an opportunity to replace the hydroelectric power generated at Glen Canyon Dam and a path forward to restoring the Grand Canyon. The geothermal reservoirs under the Salton Sea are an untapped resource that could add power to the grid as Lake Powell is slowly drained and Glen Canyon Dam is removed. Lake Powell's water could be put into Lake Mead, its downstream sister, thus keeping one fully functioning hydroelectric facility on the grid. Further, this "geo-hydro power trade" could keep the federal government solvent in its current financial contracts to provide electricity to the Southwest U.S.
The idea has already generated a bit of a buzz when Geothermal Resources retweeted this tweet:
Climate change scientists have painted a bullseye on the Southwest U.S. and the Colorado River, indicating the area will become warmer and dryer with even less flow in the Colorado River. Hydroelectricity is threatened at both Lakes Powell and Mead, as well as reservoirs in California. Salton Sea geothermal power could be a breakthrough in building a climate change-resistant Southwest while also preserving and restoring the lifeblood of the region—the Colorado River.

‘Companies Should Not Be Allowed to Use Hazardous Ingredients in Products People Use’: Michelle Pfeiffer Speaks Up for Safer Cosmetics
The beauty products we put on our skin can have important consequences for our health. Just this March, the U.S. Food and Drug Administration (FDA) warned that some Claire's cosmetics had tested positive for asbestos. But the FDA could only issue a warning, not a recall, because current law does not empower the agency to do so.
Michelle Pfeiffer wants to change that.
The actress and Environmental Working Group (EWG) board member was spotted on Capitol Hill Thursday lobbying lawmakers on behalf of a bill that would increase oversight of the cosmetics industry, The Washington Post reported.

Scientists at the United Nations' intergovernmental body focusing on biodiversity sounded alarms earlier this month with its report on the looming potential extinction of one million species — but few heard their calls, according to a German newspaper report.
The climate crisis is a major concern for American voters with nearly 40 percent reporting the issue will help determine how they cast their ballots in the upcoming 2020 presidential election, according to a report compiled by the Yale Program on Climate Change Communication.
Of more than 1,000 registered voters surveyed on global warming, climate and energy policies, as well as personal and collective action, 38 percent said that a candidate's position on climate change is "very important" when it comes to determining who will win their vote. Overall, democratic candidates are under more pressure to provide green solutions as part of their campaign promises with 64 percent of Democrat voters saying they prioritize the issue compared with just 34 percent of Independents and 12 percent of Republicans.
President Donald Trump has agreed to sign a $19.1 billion disaster relief bill that will help Americans still recovering from the flooding, hurricanes and wildfires that have devastated parts of the country in the past two years. Senate Republicans said they struck a deal with the president to approve the measure, despite the fact that it did not include the funding he wanted for the U.S.-Mexican border, CNN reported.
"The U.S. Senate has just approved a 19 Billion Dollar Disaster Relief Bill, with my total approval. Great!" the president tweeted Thursday.
