EPA chief Scott Pruitt says CO2 not a primary contributor to warming

Tom DiChristopher, CNBC

Environmental Protection Agency Administrator Scott Pruitt said Thursday he does not believe carbon dioxide is a primary contributor to global warming.

“I think that measuring with precision human activity on the climate is something very challenging to do and there’s tremendous disagreement about the degree of impact, so no, I would not agree that it’s a primary contributor to the global warming that we see,” he told CNBC’s “Squawk Box.”

“But we don’t know that yet. … We need to continue the debate and continue the review and the analysis.”

The statement contradicts the public stance of the agency Pruitt leads. The EPA’s webpage on the causes of climate change states, “Carbon dioxide is the primary greenhouse gas that is contributing to recent climate change.”

Pruitt’s view is also at odds with the conclusion of NASA and the National Oceanic and Atmospheric Administration.

Op-Ed: Trump’s Congress speech left unsaid his continued assault on our environment

Rhea Suh, THE HILL

“What kind of a country,” he asked, “will we leave our children?”

In his address to Congress and the nation on Tuesday, President Trump made sparse mention of a leading focus of his first six weeks in office — his unmitigated assault on the nation’s environment and public health.

True, Trump boasted of having worked with congressional Republicans to set mining companies free to pollute mountain streams and destroy forests, by killing the Stream Protection Rule, leaving hard hit coal communities to pay the price.

He highlighted his call to do away with two existing regulations for every new safeguard put in place, an irrational and unlawful approach that short changes the government’s ability to respond to emerging threats in a complex and changing world.

He celebrated his order to revive the Keystone XL dirty tar sands pipeline bragging that he had “cleared the way” for some of the dirtiest oil on the planet to be shipped through the breadbasket of America to be refined on our Gulf coast and shipped, mostly, overseas.

And he took pride in noting his order to sweep aside the voices of the Standing Rock Sioux and force the Dakota Access pipeline across their water sources and sacred lands.

Not great, any of that.

Trump made a fleeting plea “to promote clean air and clear water,” but he never mentioned the order he signed, just hours before, to “eliminate” the Clean Water Rule that provides needed protections for wetlands and streams that feed drinking water sources for 117 million Americans.

He steered clear of reports that he plans crippling budget cuts for the Environmental Protection Agency and to open more public land to the ravages of coal mining.

And he said nothing about his pledge to eviscerate the Clean Power Plan – the single most important measure the government has taken to fight rising seas, widening deserts, blistering heat, raging fires, withering drought and other hallmarks of climate change.

And who could blame him?

Nobody voted in November for dirty water or to put our children’s future at needless risk. Why would Trump tout an extremist agenda for which there’s little public support?

Bay Area might adopt world’s first regional oil-refinery emissions caps

Will Parrish, EAST BAY EXPRESS

On May 17, the Bay Area Air Quality Management District will consider a proposal that would make the San Francisco Bay Area the world’s first region to place limits on oil refineries’ overall greenhouse-gas and particulate-matter emissions. This new regulation, Refinery Rule 12-16, would prevent oil corporations from making the East Bay a hub of Canadian tar-sands processing, because it would enforce a cap based on historic emissions levels at the five major Contra Costa and Solano county refineries.

Not everyone agrees with this approach.

As the Express reported last June, BAAQMD executive staff members oppose the emissions cap, which they say would be illegal under state law. They also say it could lead to oil-price spikes, a stance shared by the industry.

Gov. Jerry Brown’s administration is about to weigh in on the debate, though. And at the February 1 BAAQMD board of directors meeting, Contra Costa County supervisor and California Air Resources Board director John Gioia noted that ARB Executive Officer Richard Corey is preparing a new letter detailing the agency’s position on Refinery Rule 12-16 and other refinery-related air-quality protections that BAAQMD is considering.

Ultimately, the two-dozen county supervisors and city council members who comprise the BAAQMD board of directors will decide the emissions caps’ fate. But several BAAQMD directors have said they prefer that local rules dovetail with California’s climate programs, so Corey’s letter could help make-or-break the emissions-cap proposal.

Corey reportedly has stated his intention to send the letter by the end of the month. Meanwhile, its content has become a subject of heated speculation among BAAQMD directors.

Occidental sewage transfer may be stalled by legalities

Frank Robertson, SONOMA WEST TIMES

A county plan to truck Occidental’s sewage to Guerneville for treatment and disposal appears to be stopped up for now owing to neighborhood opposition and possible legal issues.

Guernewood Park neighbors near the site where sewage would be unloaded at a Russian River Sanitation District pump station met with new Fifth District Supervisor Lynda Hopkins last week to vent their concerns about neighborhood truck traffic, potential odors and other compatibility issues if the sewage plan goes forward.

A sympathetic Hopkins told neighbors there may also be a legal problem if proposed pump station improvements, including a new paved driveway under the redwoods at the site, constitute an expansion of the sewer system onto vacant residential property next door.

“I don’t see how we can say that’s not an expansion,” said Hopkins, regarding a proposed new turnaround that sewage trucks would need on the property next to the lift station located between Highway 116 and Riverside Dr.

Sonoma County acquired the neighboring property in the 1980s as part of a legal settlement with the owner; a condition of the sale included an agreement that the county would not expand sewage system operations onto the neighboring property, said Hopkins. The previous owner had a house on the property that was in the path of a prevailing breeze carrying the lift station’s smell. The county demolished the house.

The deed restriction only surfaced last week after neighbors began asking questions about the Occidental sewage transfer plan that seemed to have been formulated with numerous discussions among Occidental Sanitation District residents but little or no dialogue with Guerneville residents whose properties would be impacted by the sewage transfer process involving from five to 15 daily truck deliveries of raw sewage arriving at the Riverside Drive lift station.

A Sonoma County Water Agency environmental review of the plan last year concluded it would have “no significant impact” on the Riverside Drive environment, but neighbors last week said they were never told about the project and are prepared to challenge the environmental finding in court.

Earth sets a temperature record for the third straight year

Justin Gillis, THE NEW YORK TIMES

Marking another milestone for a changing planet, scientists reported on Wednesday that the Earth reached its highest temperature on record in 2016, trouncing a record set only a year earlier, which beat one set in 2014.

It is the first time in the modern era of global warming data that temperatures have blown past the previous record three years in a row.

The findings come two days before the inauguration of an American president who has called global warming a Chinese plot and vowed to roll back his predecessor’s efforts to cut emissions of heat-trapping gases.

Waste from California dairy farms presents climate change challenge 

CBS SAN FRANCISCO (KPIX 5)

Got milk? Chances are it’s from California. There are more dairy cows in the Golden State than anywhere else in the country. But all that milk and cheese comes at a cost to the planet.

Tom Frantz keeps a running count. He says dairy farms have taken over his farming community in the San Joaquin Valley. “There are ten of them within what I call smelling distance of my home,” he said, noting they’ve moved in in just the last 10 years.

We’re not talking about mom-and-pop operations.

“These are milk factories,” said Frantz. “We went from zero cows to about 60,000 cows, within about five miles of where I live.”

“6,000 animals in one dairy has the waste stream of a city of half a million people,” said Frantz.

But unlike a city, most dairies don’t treat their waste. After separating out the solids to use as manure, they dump the rest of the waste into open lagoons and let it evaporate.

“This waste stream is just rotting in these giant lagoons,” said Frantz.

It’s not just the smell. The lagoons of manure also emit methane, and lots of it.  If you account for climate impacts over 100 years, which is the basis of AB 32, dairy and livestock operations are directly responsible for 5.4 percent of the state’s greenhouse gas emissions. But in the state’s short-lived climate pollution plan, that uses a 20-year global warming accounting. The impact triples to 15 percent.

“They are incredibly potent climate pollutants,” said Ryan McCarthy, Science & Technology Policy Advisor with the California Air Resources Board. “Really tackling and addressing the way that dairies manage their manure would represent one of the most significant climate programs we have in the state,” said McCarthy.

Global deal reached to limit use of hydrofluorocarbons 

Chris Johnston and staff, THE GUARDIAN

A global deal to limit the use of hydrofluorocarbons (HFCs) in the battle to combat climate change is a “monumental step forward”, John Kerry, the US secretary of state, has said.

The agreement, announced on Saturday morning after all-night negotiations in Kigali, Rwanda, caps and reduces the use of HFCs – a key contributor to greenhouse gases – in a gradual process beginning in 2019, with action by developed countries including the US, the world’s second worst polluter.

More than 100 developing countries, including China, the world’s top carbon dioxide emitter, will start taking action in 2024, sparking concern from some groups that the action would be implemented too slowly to make a difference. A small group of countries, including India, Pakistan and some Gulf states, also pushed for and secured a later start in 2028, saying their economies need more time to grow. That is three years earlier than India, the world’s third worst polluter, had first proposed.

Worldwide use of HFCs has soared in the past decade as rapidly growing countries like China and India have widely adopted air conditioning in homes, offices and cars. But HFC gases are thousands of times more destructive to the climate than carbon dioxide, and scientists say their growing use threatens to undermine the Paris accord by 195 countries, an agreement last year to reduce climate emissions.

President Barack Obama praised the deal on Saturday morning, calling the agreement “an ambitious and far reaching solution” to a “rapidly growing threat to the health of our planet”.

Climate fight targeting cows may reshape California dairies

Kurtis Alexander, SAN FRANCISCO CHRONICLE

Dairy farmer Bob Giacomini, 79, is ahead of his time, even if he didn’t mean to be.

Eight years ago, the North Bay native bought a custom motor, generator and pipeline to make electricity from an unusual source — cow manure — at his ranch along Tomales Bay. The hope was that the renewable energy would save him a few bucks and perhaps bolster the environmental bona fides of his family’s famed cheese, Point Reyes Original Blue.

As it turned out, the power system served another purpose. It helped do away with the potent greenhouse gas that’s at the heart of a new, first-of-its-kind climate law targeting agriculture.

Legislation signed this month by Gov. Jerry Brown requires California’s dairy industry to answer for its contribution to global warming by making a 40 percent cut in methane emissions in coming years. The gas, which heats the atmosphere 20 times faster than carbon dioxide, comes from the butts and burps of bovines.

One U.N. report blames livestock, which has largely escaped climate regulation, for 14.5 percent of the planet’s heat-trapping gases, as much as planes, trains and automobiles combined.

Earth CO2 levels: Have we crossed a point of no return?

Weston Williams, THE CHRISTIAN SCIENCE MONITOR

The annual low for atmospheric concentrations of carbon dioxide has crossed the 400 parts per million threshold, a level not seen for millions of years.

Earth may have passed a significant symbolic threshold as the global climate continues to grow warmer.Usually, September marks a low in the amount of carbon dioxide (CO2) in the atmosphere. This concentration sets the bar over which levels of the greenhouse gas will fluctuate throughout the next year. But this September, CO2 levels are staying high, at around 400 parts per million, and many scientists think that we will not see levels of the greenhouse gas drop below that threshold within our lifetimes.

Earth has been steadily building up CO2 in the atmosphere since the Industrial Revolution, but the 400 ppm landmark is creating a new normal that hasn’t been seen on this planet for millions of years.

“The last time our planet saw 400 ppm carbon dioxide in our atmosphere was about 3.5 million years ago, and global climate was distinctly different than today,” David Black, associate professor in the School of Marine and Atmospheric Sciences at Stony Brook University in New York, tells The Christian Science Monitor in an email.

Sonoma County Climate Action 2020: Litigation over the county’s Climate Action Plan

Fred Allebach, SONOMA VALLEY SUN

The County of Sonoma and it’s nine cities together are formulating a plan to collectively decrease greenhouse gas emissions. This plan is called Sonoma County Climate Action 2020, and until a lawsuit was recently filed challenging some of its underlying assumptions, the cities were prepared to sign onto the plan. This report provides background information about the plan, and where things stand today.

In 1850 the Industrial Revolution kicked off an era of greenhouse gas (GHG) emissions that began to accumulate in the earth’s atmosphere. As the world’s population grew by the billions, human-caused GHG emissions environmental impacts became greater and greater, especially since the 1950s.

By the mid 1980s, human-caused climate change was acknowledged as a serious problem. and precipitated the first articulation of sustainability principles. These include concepts such as the triple bottom line, full cost accounting and systems literacy.

California, being a vanguard state, in 2006 the Schwarzenegger administration began a series of measures and bills that put the state on track to reducing GHG emissions to 15% below 1990 levels by the year 2020.

Sonoma County and Individual Cities Take Local Action

Sonoma County took the ball and ran with it, each jurisdiction setting even deeper reduction goals (25% below 1990) and creating the nation’s first Regional Climate Protection Authority (RCPA) in 2009.  This was seen as cutting edge throughout the entire United States. The RCPA then worked to create a Climate Action 2020 plan for Sonoma County, finalized in July of 2016.

Each Sonoma County municipality was included in the Climate Action Plan (CAP), and able to choose from among a slate of possible voluntary local GHG emissions reduction measures that would be their contribution to the overall plan. A combination of the number of local measures chosen from the RCPA list, plus the overall amount of carbon reduced, added up to the percent of a city’s contribution to the CAP.
