Porter Ranch Is Only Tip of the Iceberg Exposing Catastrophic Impacts of Natural Gas

Natural gas is not cleaner than coal.

But thanks to boatloads of advertising and campaign contributions, oil and gas lobbyists has convinced many politicians, including President Obama, that replacing coal with natural gas is a viable way to stave off catastrophic climate change.


But it isn't. The now-famous Aliso Canyon methane leak, its impacts on thousands of residents of near Porter Ranch and its damage to the climate is just the latest and most public example showing that we need to keep natural gas in the ground, not burn it.

The oil and gas industry's argument for natural gas boils down to this: to generate electricity, burning natural gas is cleaner than burning coal. While that is true, it's only part of the story. But it's the only part industry tells because it's the only part they like. Unfortunately for all of us, though, natural gas is far more than just a replacement utility-scale fossil fuel.

SoCalGas, a division of Sempra Energy, provides natural gas not just to power plants, but to 21 million customers in Southern California. “Now you're cooking with gas," is the Bob Hope adage from the 30's and 40's as natural gas began to be piped into homes for heating and cooking. To look at it another way, the leaking Aliso Canyon gas storage facility supplies millions of kitchen ovens with the blue flame prized by home chefs.

But to see the true cost of natural gas we need to look beyond the burner.

The environmental and community health damage caused by fracked natural gas extraction is well known at this point, and science is confirming its danger with every new peer-reviewed study.

Californians' attention turned to the problem of aging pipeline infrastructure in our cities, when a suburban neighborhood in the town of San Bruno was destroyed in a 2010 natural gas pipeline explosion. Then Nathan Phillips at Boston University used gas analyzers to develop 3-D “methane maps" in urban environments, estimating 7-15 percent of global manmade methane pollution could be coming from pipes in cities bringing natural gas to consumers.

Until Aliso Canyon, we weren't looking at the step in the supply chain before urban pipelines—storage facilities. Refined natural gas has been stored in former oil wells at Aliso Canyon since the 70's; when the oil wells were emptied, they were repurposed for storage of natural gas. The volcano of methane that is now California's largest single source of greenhouse gases is coming from a broken well that was last inspected in 1976. The LA Weekly reports that the well's safety valve was inexplicably removed in 1979. Among the hundred at the facility, other wells also lack safety valves.

Aliso Canyon was a disaster waiting to happen. The facility was old, poorly managed and experienced abysmal oversight. Gov. Jerry Brown finally declared a state of emergency last week, directing state agencies to take unprecedented action on underground gas storage in the Golden State.

There are more than 300 similar facilities around the country. We need to to make sure that we don't have other climate and health disasters waiting to happen in California and around the U.S. We need:

  • An emergency statewide effort to shut down facilities that lack basic safety equipment, including Aliso Canyon. Gas storage wells that lack shut off valves should be taken offline before other Porter Ranches happen.
  • Increased oversight and management of these facilities.
  • Support for residents affected by pollution, including health care as well as financial compensation.
  • A rapid transition for consumers away from gas. The Solutions Project has mapped out a 100 percent fossil fuel free plan by 2050. This transition would protect communities from underground storage risks, gas line leakage and explosions like the one in San Bruno.

We've already wrapped our heads around a rooftop solar revolution and what it might mean for distributed energy generation rather than big boxes of fossil fuels. Now it's time to start planning to get rid of the blue flames on our stovetops, water heaters and furnaces. There is an electric or solar electric alternative to every natural gas appliance. We can't just cut natural gas's electric cord; we have to cut the pipeline too.

A Record 589 Sea Turtles Killed By Florida's Toxic Red Tide

Florida's longest red tide in more than a decade has killed scores of the state's most iconic marine animals.

The current outbreak, which began in October 2017 off southwest Florida, has been tied to a record 589 sea turtle deaths and 213 manatee deaths, the Herald-Tribune reported, citing figures from the Florida Fish and Wildlife Conservation Commission.

Wildlife Under Siege at the World’s Oldest Lake

By Marlene Cimons

Lake Baikal is the world's oldest and deepest lake. It's at least 20 million years old, and roughly a mile deep at its lowest point. The Siberian lake contains holds more water than all the North American Great Lakes combined, what amounts to more than one-fifth of all the water found in lakes, swamps and rivers. It was formed by the shifting of tectonic plates, which created a valley that filled with water. That shift continues today at a rate of around 1 to 2 centimeters year, meaning the world's biggest lake is only getting bigger.

U.S. Oil and Gas Industry Is Drilling Us Towards Climate Disaster

By Kelly Trout

As the 116th Congress commences, in the wake of dire reports from climate scientists, the debate over U.S. climate policies has taken a welcome turn towards bold solutions. Spurred on by grassroots pressure from Indigenous communities, the youth-led Sunrise Movement and communities from coast to coast fighting fossil fuel infrastructure, Capitol Hill is alive once again with policy proposals that edge towards the scale required to address the crisis we're in.

Half of Michigan's Bumblebee Species in Decline, One Extinct

Honeybees get a lot of attention for their worrisome decline, but many species of bumblebees—which are key pollinators—are also in trouble.

In Michigan, half of its bumblebee species have declined by 50 percent or more, Michigan Radio reported.

2018 Was the Hottest Year Ever Recorded for Our Oceans

The year 2018 was the hottest year for the planet's oceans ever since record-keeping began in 1958, according to a worrisome new study from international scientists.

The findings, published Wednesday in the journal Advances in Atmospheric Sciences, noted that the five warmest years for our oceans were the last five years—2018, 2017, 2015, 2016 and 2014 (in order of decreasing ocean heat content).

Senate Shouldn’t Put Wheeler at the Wheel of the EPA

By Ana Unruh Cohen

As the longest government shut down in history drags on, and the experts protecting our air and water remain off the job, the Senate is barreling forward to put Andrew Wheeler at the wheel of the U.S. Environmental Protection Agency (EPA). He is unfit for this public trust.

In his seven-month tenure as the acting administrator at EPA, Wheeler's relentlessly pushed to advance the pro-polluter agenda launched by Scott Pruitt, the worst administrator in the agency's storied 48-year history. Wheeler may lack Pruitt's scandals, but he's no improvement.
