Big Oil & Climate Lawsuits — KQED Forum 10am PT

I’ll be a guest on KQED Forum this morning at 10am discussing lawsuits against the oil industry and its deceptive practices related to climate change.

Most recently, 18 California children sued the EPA for failing to protect them from climate change. The lawsuit is one of many efforts to hold the fossil fuel industry to account that reporter Dharna Noor highlighted in her series for the Guardian US called “Big Oil Uncovered.” We’ll discuss the strategies oil and gas companies are using to delay or avoid action on climate change — and the people and policies who are taking them to task.

Climate Scientist Michael Mann & Latin American Environmental Activists — Your Call 10am PT

On today’s Your Call One Planet Series, I’ll be guest hosting and talking to University of Pennsylvania renowned climate scientist Dr. Michael Mann, presidential distinguished professor in the Department of Earth and Environmental Science and director of the Penn Center for Science, Sustainability, and the Media.

He will discuss his new book, Our Fragile Moment: How Lessons from Earth’s Past Can Help Us Survive the Climate Crisis.

Then we’ll discuss Water for Life, a documentary film that tells the story of three Indigenous activists in Central and South America, fighting to protect their ancestral lands and water rights.

The film follows Alberto Curamil, a Mapuche chief in Chile; Francisco Pineda, a corn-grower in El Salvador; and the late Berta Cáceres, of the Lenca in Honduras, as they face jail and murder while leading movements to safeguard their drinking water and irrigation water from multinational corporations and corrupt governments.

Health Impacts Of Wildfire Smoke — Your Call 10am PT

On today’s Your Call, I’ll guest host a discussion of the health hazards of wildfire smoke. Last week, the San Francisco Bay Area experienced its first taste of this year’s fire season with the Air Quality Index numbers soaring into a range deemed unhealthy for the general population.

According to the National Oceanic and Atmospheric Administration (NOAA), wildfires are bigger, more severe, and more common today in the western United States than at any time in the last four decades. The recent fires in Maui that destroyed 80 percent of the seaside town of Lahaina are just the most recent tragic example. In California, nearly half of the state’s largest fires on record occurred in the past five years.

But immediate destruction from wildfires is only part of the picture. Wildfire smoke can have lasting impacts on human health. A new study from Lancet Planet Health found that smoke from the world’s worsening wildfires is now killing 33,510 people every year. It not only exacerbates respiratory illnesses like asthma, but is also linked to increased risk of cancer, heart attacks, and preterm birth.

So what can we do to keep ourselves safe as wildfires rage on? Joining me will be:

  • Quinn Redwoods, founder and director of Mask Oakland
  • Julie Johnson, journalist, staff writer at San Francisco Chronicle’s climate and environment desk
  • Dr. Neeta Thakur, associate professor of pulmonary and critical medicine at UCSF, medical director of the outpatient pulmonary clinic at San Francisco General Hospital, co-director of the Partnerships for Research in Implementation Science for Equity (PRISE) Center.
  • Dr. Sheri Weiser, internist and professor of medicine in the HIV, Infectious Diseases and Global Medicine division at UCSF, co-founding director of the University of California Center on Climate Change, Health and Equity

Infill Housing & Conservationists Finally Team Up

A major new piece of housing and climate legislation was introduced in California this month, and it’s been a long time coming. AB 68 (Ward) finally sets forth a powerful template for where the state should encourage new housing and where it should avoid planning for more, based on climate and environmental hazards. It represents the culmination of a long-sought alliance between major housing advocates like California YIMBY and conservation groups like The Nature Conservancy.

So where should the state build more housing, according to AB 68? It defines those places in the following “climate smart” ways:

  • In a high or moderate income area, as defined by state affordable housing tax credit maps, to prioritize more housing in high-opportunity and well-resourced areas and minimize displacement of low-income renters
  • Within 1/2 mile of major transit or an area where residents drive below-average distances on a per capita average, in order to reduce overall driving miles in the state
  • Within a mile of a cluster of at least six types of locations like restaurants, bars, coffee shops, supermarkets, parks and hardware stores, among others, to ensure rural and exurban infill areas aren’t left out, as well as places without access to transit.

If a housing development is proposed in these areas, the project gets “ministerial” approval (i.e. exempt from environmental review), and a local government cannot limit the development beyond any of the following:

  • Setback greater than four feet from any side
  • Height limit less than 50 feet
  • Maximum lot coverage of less than 60 percent
  • Minimum parking requirement
  • Floor area ratios (i.e. the building’s total floor area in relation to the size of the lot/parcel, indicating overall density) less than 1.0. to 1.5, depending on criteria met

There are additional requirements to protect existing affordable housing and ensure consistency with SB 375 plans, among others.

And where should planning for denser development in the state be limited? AB 68 describes these “climate risk lands” as within high-severity wildfire and flood zones, or having a sea level rise risk according to the latest science. They also must be not currently zoned for housing or have existing urbanized communities on them.

In these areas, local governments cannot increase existing housing densities or allow subdivisions, and they cannot approve any extension of water or sewer services, unless certain exceptions can be met, such as an approved housing element and a statement of housing necessity, among other conditions.

In short, AB 68 finally provides the much-needed, legislatively endorsed map for where the state should grow and where it should avoid putting more people into harm’s way. If successful, AB 68 will arguably be the single biggest climate bill that the state has passed in over a decade, given the centrality of land use and housing to meeting our climate goals. The fight to pass it will not be easy, but AB 68 has a powerful coalition to support it, along with a well-conceived solution to the state’s urgent and related challenges of climate and housing.
