Sonoma County supervisors remove granny unit restrictions on some farm parcels

Martin Espinoza, THE PRESS DEMOCRAT

Last year, Jennifer Mann sold her home in Santa Rosa’s Junior College District around the same time her son and daughter-in-law sold their home in downtown Sebastopol.

With the goal of establishing a “family compound,” they bought a home in rural Sebastopol, a unique, three-story, dome-shaped house that looks like a cross between a barn and an observatory.

It’s cramped for a growing family. Mann, a retired Santa Rosa Junior College employee, lives on the first floor, her two grandkids on the second and her son and daughter-in-law on the third.

“We have three acres and we always planned to build a second unit for me, so I could live on the land,” Mann said.

Until recently those plans were hindered by a county zoning restriction known as a “Z District,” which prohibits the construction of granny units in certain agricultural zones.

The restriction was aimed at preserving the county’s agricultural resources and preventing nonfarming residences from encroaching into agricultural lands. However, many smaller parcels restricted by a Z District do not qualify for farm-related housing because they do not meet size and agriculture production requirements.

The world’s oceans are in danger, major climate change report warns

Brad Plumer, THE NEW YORK TIMES

Climate change is heating the oceans and altering their chemistry so dramatically that it is threatening seafood supplies, fueling cyclones and floods and posing profound risks to the hundreds of millions of people living along the coasts, according to a sweeping United Nations report issued Wednesday.

The report concludes that the world’s oceans and ice sheets are under such severe stress that the fallout could prove difficult for humans to contain without steep reductions in greenhouse gas emissions. Fish populations are already declining in many regions as warming waters throw marine ecosystems into disarray, according to the report by the Intergovernmental Panel on Climate Change, a group of scientists convened by the United Nations to guide world leaders in policymaking.

“The oceans are sending us so many warning signals that we need to get emissions under control,” said Hans-Otto Pörtner, a marine biologist at the Alfred Wegener Institute in Germany and a lead author of the report. “Ecosystems are changing, food webs are changing, fish stocks are changing, and this turmoil is affecting humans.”

Hotter ocean temperatures, combined with rising sea levels, further imperil coastal regions, the report says, worsening a phenomenon that is already contributing to storms like Hurricane Harvey, which devastated Houston two years ago.

For decades, the oceans have served as a crucial buffer against global warming, soaking up roughly a quarter of the carbon dioxide that humans emit from power plants, factories and cars, and absorbing more than 90 percent of the excess heat trapped on Earth by carbon dioxide and other greenhouse gases. Without that protection, the land would be heating much more rapidly.

But the oceans themselves are becoming hotter, more acidic and less oxygen-rich as a result, according to the report. If humans keep pumping greenhouse gases into the atmosphere at an increasing rate,marine ecosystems already facing threats from seaborne plastic waste, unsustainable fishing practices and other man-made stresses will be further strained.

Good and bad news in California’s greenhouse gas emission inventory

Irwin Dawid, PLANETIZEN

Executive Summary: California Greenhouse Gas Emissions for 2000 to 2017

Overall greenhouse gas emissions in California dropped 1% in 2017, according to the inventory by the California Air Resources Board, which includes a 9% drop in emissions from electricity generation and a 1% increase in transportation emissions.

“The California Air Resources Board said Monday that the state’s emissions fell 1% in 2017, the most recent year available, to 424 million metric tons,” writes J.D. Morris, a business reporter covering energy and California’s clean power initiatives for the San Francisco Chronicle reporter covering energy. “The state is now well past its 2020 goal of reducing greenhouse gas levels to 1990 levels — 431 million metric tons.”

Clearly, the big success story is that carbon-free sources of energy, “[f]or the first time since the state began tracking greenhouse gas emissions, powered most [52%] of the state’s electric grid,” notes Morris.

Electricity generation, from in-state and out-of-state sources, accounted for 15 percent of greenhouse gas emissions by economic sector, the third-highest after transportation (41%) and industrial (24%).

The news is not so positive when it comes to transportation. For the fifth consecutive year, emissions have increased, although the increase in 2017 was “the lowest growth rate over the past 4 years,” notes the second bullet in the executive summary of the 24-page report, California Greenhouse Gas Emissions for 2000 to 2017 [pdf]. Vehicle tailpipe emissions accounted for 37% of emissions in 2017.

Land use policy key to reining in global warming, U.N. report warns

Julia Rosen and Anna M. Phillips, THE SAN DIEGO UNION-TRIBUNE

Slashing greenhouse gas emissions from cars and power plants won’t be enough to avoid the worst effects of climate change. To meet the goals of the Paris climate accord, experts say, humanity also needs a new approach to managing the land beneath its feet.

A sweeping new report from the United Nations’ Intergovernmental Panel on Climate Change highlights the myriad ways that rising temperatures have impacted agriculture, wildfire risk, soil health and biodiversity. The report also examines how land and its uses can exacerbate the effects of global warming — or help mitigate them.

“It tells us that land is already doing a lot of service for us, but also that we can do a lot with land,” said Louis Verchot, a forester at the International Center for Tropical Agriculture in Palmira, Colombia.

A summary of the IPCC’s assessment was released Thursday after a marathon overnight negotiating session in Geneva. It will inform United Nations climate negotiations in Santiago, Chile, later this year, when countries will revisit their pledges to reduce emissions.

One of the report’s major themes is that forests play an important role in absorbing the carbon dioxide generated by human activities, and protecting them is crucial to reining in warming.

The report also emphasizes the need for a new approach to agriculture that would feed a growing population while using natural resources more sustainably.

“Limiting global warming to 1.5 or even 2 degrees [Celsius] will involve removing carbon dioxide from the atmosphere, and land has a critical role to play,” said Jim Skea , co-chair of the climate change mitigation working group.

Open letter from a distressed climate scientist

Javier Hernández, Director of the Climate Research Center, Sonoma State University

I am addressing this open letter to the Sonoma County government government officials, the California governor, and to all policymakers in the world, especially to those in areas where climate change-related phenomena (extreme heat, droughts, wildfires, heavy rainfall, floods, hurricanes, sea-level rise, storm surge, tornadoes) and other geophysical processes exacerbated by climate change like earthquakes, tsunamis, volcanic eruptions, etc. are already causing ample biophysical, social and economic devastation.

More recently, scientists like myself, are confirming that climate change-related processes are happening much earlier than expected and that urgent and massive emergency action must be undertaken.

Climate change accentuated phenomena are impacting us now and their frequency and intensity are set to increase even if all anthropogenic greenhouse gases (GHG) emissions are stopped today. For this reason, even though stopping anthropogenic GHG emissions and drawing down existing carbon in the atmosphere at maximum speed is still very important to mitigate climate change, it is paramount to deploy deep climate adaptation strategies in order to better cope with our present and future climate reality. Deep climate adaptation means to undertake all the necessary economic, structural, organizational, societal, etc., transformations to minimize the impact of climate change vulnerabilities particular to each region.

This open letter is not intended to convince anyone on whether climate change is happening or not, or whether is occurring because of natural forces, mostly human activities or a combination of both factors. The aim of this open letter is to discuss the most important problem related to climate change, the issue of living in a world where climate change enhanced phenomena are impacting us now and will become the norm in our very near future.

I’m a very distressed climate scientist that has done research on extreme weather and its relations to climate variability and change. I’ve experienced firsthand the devastating impacts of climate change accentuated phenomena, with more powerful Hurricanes impacting my homeland of Puerto Rico and more frequent and larger wildfires in California where I currently live. I am in the front lines of the climate change apocalypse.

The Intergovernmental Panel On Climate Change (IPCC) Report of October 2018 presented a dire state of the climate which, in reality, understated the true, even more disastrous, state of the climate. The Report claimed that with global CO2 emissions reductions of 45% below 2010 levels by 2030 and zero emissions by 2050, the average global temperature increase above pre-industrial times would likely stay below 1.5º C. The exclusion of the self-reinforcing climate change amplifying feedbacks (f.i. ice sheet disintegration, loss of albedo effect, heat storage by the oceans and release of methane from melting permafrost) in their climate change models, makes those suggestions irrelevant and misleading. The Report suggests that there is still a “carbon budget” that safely allows for more GHG emissions, which is not supported by the more realistic models that include the amplifying feedbacks, and by the now almost constant extreme and usually “unprecedented” climate change-related events happening around the world. There is no safe carbon budget left.

Because of those amplifying feedbacks alone, the increase of 1.5ºC is going to be surpassed significantly sooner than 2030, even if all anthropogenic GHG emissions are stopped immediately. The current global average temperature increase is close to 1.2º C and many areas of the Earth are already beyond a 1.5º C increase. For instance, Canada is at about 2 times the global average temperature increase and the Arctic Region (including Northern Canada) is at about 3 times the average.

The already major activation of the self-reinforcing climate change amplifying feedbacks, as a consequence of anthropogenic GHG emissions, makes the existing climate change mostly irreversible and leaves a short, but difficult to quantify, time for humans to mitigate further climate change aggravation by stopping all GHG emissions and removing GHG from the atmosphere, before a runaway climate change gets established.

As a scientist and as a being of this world I argue that we must stop debating whether we act or not on climate change. My position on the issue is clear, we must take bold climate action to prepare our societies for a more extreme world at the brink of societal collapse. We must embrace the fact that more devastating climate change effects will occur in the near future, so we must quickly begin our deep adaptation process to live in this new more climate extreme world.

If we don’t want to witness the end of organized civilization as we know it, we must act now. For that reason, I urge local, state and federal/national policymakers to accept the scientific consensus and the empirical reality that climate change is impacting us now and that it will continue to impact us in the immediate and long term future. After acknowledging our climate reality, I ask policymakers at all levels to issue official climate disaster state of emergency executive orders to make all resources available to deal with the climate change crisis which, ultimately, has the potential for the extinction of humanity.

I urge our governments to develop emergency measures that would allow us to prepare all of the infrastructure (roads, dams, buildings, parks, bridges, emergency-response infrastructure) and essential sustaining systems like farming, water supply, and health care, in our communities to the impacts of climate change. If we take bold action now, we can employ every able person in our communities in the 100% renewable energy transformation, infrastructure resiliency efforts and environmental restoration measures that would allow us to be better prepared to cope with climate change impacts now and in the very near future.

The impacts of climate change will not stop in the near future, even if we dropped all of our GHG emissions to zero. For that reason, I urge policymakers to focus on developing a more just and resilient local, national and global society that would allow all of its members to have a dignified life under our current and future climate reality.

In order for all of this to happen, policymakers need to accept one very important fact, we cannot continue with our current unsustainable economic activities that view the Earth as merely a collection of resources to be exploited in eternity for the sake of never-ending economic growth and wealth accumulation. Our voracious economic growth since the industrial revolution, almost exclusively dependent on fossil fuels, is what brought us here and it needs to stop if we want to avoid the worst impacts of climate change.

If we want to avoid the worst of the very likely climate apocalypse in our horizon, we must act now and work together to build a more just and resilient world for us, our children and all of humanity. It is impossible to put a brake on all of the climate change impacts that will threaten us now and in the very near future, but we can still mitigate Climate Change, build more resilient communities, restore key ecosystems and relinquish old unsustainable practices that would allow us to live a dignified life in a more climate extreme world.

Vision for housing and hotel development in northern Healdsburg challenged in court

Kevin Fixler, THE PRESS DEMOCRAT

Healdsburg has begun its review of a developer’s proposal to build what would be the city’s largest housing project, a plan on the north end of town that has restoked the fiery debate in this Wine Country destination over the pace of residential growth and hotel development.

Already, the proposal by Southern California-based Comstock Homes has drawn a legal challenge against the city, with opponents asserting the expansive development would run afoul of state environmental regulations.

The project, on a vacant former lumber yard bounded by Healdsburg Avenue and Highway 101 north of Simi Winery, currently calls for more than 350 units of housing and a 120-room hotel.

The housing would be split between 132 income-restricted rental units for the local workforce and a 220-unit senior living community. Plans also call for 20,000 square feet of retail space.

“We have a vision to provide something sorely needed in the community,” said Debra Geiler, Comstock’s director of entitlements. “The mix of housing units and the hotel and all of it is sort of the economic balance. If we succeed, what we will be able to provide to Healdsburg is a paradigm shift in community design and creating neighborhoods.”

But Sebastopol-based California River Watch has filed suit contending that Healdsburg failed to lawfully account for the greenhouse gas emissions the luxury hotel would generate. The lawsuit is a key piece of the group’s goal to force local governments to more closely account for the climate impacts of commercial growth and the region’s tourism economy.

We must transform food production to save the world, says leaked report

Robin KcKie, THE GUARDIAN

Attempts to solve the climate crisis by cutting carbon emissions from only cars, factories and power plants are doomed to failure, scientists will warn this week.

A leaked draft of a report on climate change and land use, which is now being debated in Geneva by the Intergovernmental Panel on Climate Change (IPCC), states that it will be impossible to keep global temperatures at safe levels unless there is also a transformation in the way the world produces food and manages land.

Humans now exploit 72% of the planet’s ice-free surface to feed, clothe and support Earth’s growing population, the report warns. At the same time, agriculture, forestry and other land use produces almost a quarter of greenhouse gas emissions.

In addition, about half of all emissions of methane, one of the most potent greenhouse gases, come from cattle and rice fields, while deforestation and the removal of peat lands cause further significant levels of carbon emissions. The impact of intensive agriculture – which has helped the world’s population soar from 1.9 billion a century ago to 7.7 billion – has also increased soil erosion and reduced amounts of organic material in the ground.

In future these problems are likely to get worse. “Climate change exacerbates land degradation through increases in rainfall intensity, flooding, drought frequency and severity, heat stress, wind, sea-level rise and wave action,” the report states.

Berkeley became first US city to ban natural gas. Here’s what that may mean for the future

Susie Cagle, THE GUARDIAN

Berkeley this week became the first city in the United States to ban natural, fossil gas hook-ups in new buildings.

The landmark ordinance was passed into law on Tuesday, after being approved unanimously by the city council the previous week amid resounding public support.

Although Berkeley may be pushing the vanguard, the city is hardly alone. Governments across the US and Europe are looking at strategies to phase out gas. In California alone, dozens of cities and counties are considering eliminating fossil fuel hook-ups to power stoves and heat homes in new buildings, while California state agencies pencil out new rules and regulations that would slash emissions.

Natural gas, it seems, has become the new climate crisis frontline.

Berkeley’s ordinance, which goes into effect on 1 January, will ban gas hook-ups in new multi-family construction, with some allowances for first-floor retail and certain types of large structures.

The reasons behind the decision are multifold. Energy use in buildings accounts for about 25% of greenhouse gas emissions in California. If the state is to meet its goal of 100% zero-carbon energy by 2045, the gas will have to go.

Do Americans need air-conditioning?

Penelope Green, THE NEW YORK TIMES

Modernity was born 116 years, 11 months, two weeks and two days ago, at a printing plant in the East Williamsburg section of Brooklyn, when a junior engineer named Willis Carrier devised a contraption that blew air over water-filled pipes to dry out the humidity that was gumming up the pages of a humor magazine called Judge.

And in that moment (well, within a few decades), entire industries and geographies were transformed, and new technologies made possible, including, terribly, the internet: Without cooling, there would be no server farms.

Nearly 90 percent of American households now have some form of air-conditioning, more than any other country in the world except Japan, though that will change as global warming alters more temperate zones, and swelling populations and rising incomes in hot zones mean the folks there will clamor for AC, too.

On an overheated planet, air-conditioning becomes more and more desirable, solving in the short term the problem it helped create.

It is another paradox that even as architects and engineers are making ever more efficient buildings to meet energy standards set by cities like New York, where a new law says that buildings over 25,000 square feet must reduce their carbon emissions by 80 percent by 2050, we are still freezing in our offices and fighting with our partners over whether to turn on the Friedrich.

Amazon votes down employee-backed climate resolution

Olivia Rosane, ECOWATCH

Amazon shareholders voted down an employee-backed resolution calling for more aggressive action on climate change at their annual meeting Wednesday, The Los Angeles Times reported.

The employee-filed resolution asked the company to develop a public plan for responding to extreme weather events and weaning itself off of fossil fuels. It was publicly backed by more than 7,600 employees, who signed their names to an open letter, a novel tactic for tech employee activism, The New York Times said.

Amazon Employees for Climate Justice, the group that grew out of the resolution, said in a press release they will file another if the company’s board doesn’t increase its climate commitments.

“The enthusiasm is overwhelming,” Amazon employee Rebecca Sheppard, who works in air cargo operations, told the Los Angeles Times. “We’ll be back.”

Ahead of the vote, the resolution had won the support of two of the largest proxy advisory firms in the U.S. — Glass Lewis and Institutional Shareholder Services (ISS). Glass Lewis said that Amazon was less transparent about its sustainability plans than similar companies, The New York Times said. However, the Amazon Board formally opposed the resolution, meaning it faced an uphill battle to gain the 50 percent of support it would have needed to pass, according to the employee press release. Amazon will release the final vote tallies Friday, the company told the Los Angeles Times.
