Sea level rise, way worse than we thought (again)
- posted by Laura
A paper this week in what is arguably the world's most prestigious scientific journal, Nature, says that the last time the Earth warmed up as much as it will under climate change, sea levels rose about 8 meters. This means that global sea level rise over the coming decades may be about twice as worse as we thought. When we published two articles in the Urbanist last month on the topic of sea level rise, we reported that sea level rise might possibly be 5-7 m higher in 300 years, and very likely 1.5 m by 2100. (these were the most well-documented worst-case scenario numbers I could find).

This new paper - a great analysis here - says sea level rise is very likely going to rise 20-30 feet (6-9 m) if we hold temperature to about 3.6 degrees F higher than today. We don't know when we'll get these levels.  We only know we'll be committed to them even if we somehow manage to slow down climate change.

As of today's proposals in Copenhagen, the temperature in 2100 is going to be 7 degrees F hotter.

A primer on federal climate policy
- posted by Laura
Our friends at the Sightline Institute in Cascadia have put together a primer on the federal climate bill, aka the American Clean Energy and Security Act (ACES), aka Waxman-Markey, that passed the U.S. House of Representatives late last week.  Cap and Trade 101 features what you need to know about cap and trade, pollution auctioning, offsets, and why national climate legislation is good for families.  For one slightly technical analysis of the bill, also check out Sightline's blog post, "14 Things I Love - and 6 I Hate - About Waxman-Markey". Get ready for a showdown as this groundbreaking legislation is debated in the Senate in the fall.

This week at SPUR: world renowned climate scientist Ken Caldeira
- posted by Julie

SPUR is thrilled to welcome Ken Caldeira, head of the Carnegie Institution for Science's Department of Global Ecology at Stanford University, to the Urban Center for a lunchtime forum.

The details:
Wednesday, October 28, 12:30 - 1:30 p.m.
Free for SPUR members. General admission is $5.
Location: SPUR Urban Center, 654 Mission St. (between New Montgomery & Third).

Renowned for his groundbreaking research on ocean acidifcation, Caldeira's been in the news this month for publicly chiding Superfreakonomics authors Steven D. Levitt and Stephen J. Dubner for misrepresenting his research on geo-engineering as a substitute for agressive mitigation strategies aimed at reducing greenhouse gas emissions. (In fact, while Caldeira knows a lot about weather manipulation--perhaps more than any other climate scientist working right now--he views it as a last resort, only to be employed once we are certain about its many risks.)

Here's a bio of Caldeira from an Oct. 22 post on the Guardian Environment Network (which republished a great interview conducted by Yale 360):

Atmospheric scientist Ken Caldeira first became known for his groundbreaking work on ocean acidification, a phrase originally coined as a headline for one of his papers. Of late, however, Caldeira's research has led him into the controversial area of geo-engineering — the large-scale, deliberate manipulation of the Earth's climate system.

Many scientists have shied away from the subject because they feel it is a wrongheaded and dangerous path to pursue. But Caldeira — who heads a research lab at the Carnegie Institution for Science's Department of Global Ecology at Stanford University — has not been so dismissive, in part because his climate modeling has demonstrated that some geo-engineering schemes may indeed help reduce the risk of climate change. In fact, few scientists have thought harder about the moral, political, and environmental implications of geo-engineering.

Caldeira has become a focal point recently in the controversy surrounding the publication of Steven D. Levitt and Stephen J. Dubner's SuperFreakonomics, the follow-up to their previous best-seller, Freakonomics. A chapter of the book that deals with geo-engineering and quoted Caldeira was circulated on the Internet prior to the book's publication and was widely criticized for its poor understanding of climate science and its cynical, contrarian perspective.

Explore climate action activities with the San Francisco Bay Area Climate Action Portal!
- posted by Tessa
Climate change is a global problem, and the San Francisco Bay Area is especially threatened. Around one thousand miles of shoreline frame the region, so we will be greatly affected by sea level rise and intensified storm activity.

Given our particularly risky situation, the Bay Area is on the forefront of climate change action. The Bay Area Air Quality Management District and the Institute for Local Government have collaborated to release the San Francisco Bay Area Climate Action Portal, a web based tool designed to provide local governments with the resources they need to take action on climate change.

The site provides access to a wide variety of information including climate change policy, science and current news, inventory and statistical information, project examples throughout the Bay Area, and goals already accomplished. The portal also has an interface for climate change communication, linking people together for meetings, events, online discussion forums, list-serves, and blogs.

While attacking climate change may often require extremely site-specific strategies, there are many issues such as transportation that we need to approach as a megaregion. The Climate Web Portal allows Bay Area cities to learn from one another, while also helping local governments discover their own unique needs.

A Guide to California's SB 375
- posted by Laura
NRDC has just released a guide to SB 375, the nation's first legislation to link transportation and land use planning with global warming.  The goal of this legislation is to foster development patterns that reduce the need to drive. Household transportation is the single largest and fastest-growing source of global warming pollution in California. SB 375 will also help save money for households and taxpayers (through reduced infrastructure costs), reduce air pollution, conserve water, and protect farmland and open space.

Picturing climate change: special event!
- posted by Laura

This Wednesday, join the Alaska Conservation Foundation for an evening with National Geographic photographer James Balog. Mr. Balog, an award wininng photographer for over 25 years, will share his groundbreaking work to capture the reality of climate change by photographing the world’s shrinking glaciers. Through time-lapse footage, Mr. Balog will share his efforts to design equipment, underwrite, and produce one of the world’s most convincing records of climate change. For more information (and stunning photographs), visit www.extremeicesurvey.org. Half of the U.S. coal reserves, by the way, lie in Alaska—making it a very important front line for stopping global climate change.

Event details: Wed, Nov. 18, Fort Mason Officer's Club, 1 Fort Mason, San Francisco
Program (Free, but RSVP required):  6:30-7:30 pm
RSVP: Lorraine Guyer, at acfinfo@alaskaconservation.org, or call (907) 276-1917.

Moving Cooler
- posted by Laura

Transportation-related greenhouse gas (GHG) emissions are the fastest growing source of emissions in the U.S., and are currently responsible for almost 30% of the nation's total GHG output. A new ULI report, Moving Cooler, presents different strategies for making our transportation systems more sustainable.  It proposes nine categories for improvement, including pricing/taxes, land use and smart growth, transit improvements, ridesharing, intelligent systems, and more. Going beyond other reports of its kind, it not only looks at the costs and effectiveness of different strategies, but considers them in various combinations. Although you have to buy the book, you can get an overview of its findings here.

Coming soon: energy efficiency loan program
- posted by Laura

SPUR's analysis of the cost-effectiveness of various options for local government to reduce carbon emissions has gotten around. Our evaluation showing that in San Francisco, a low-interest loan program to finance home energy efficiency retrofits would be more cost-effective than new incentives for renewable energy installations, was featured in an EPA presentation for local governments on how to use stimulus funding. The presentation is accessible on ICLEI's California Region site. And it looks like such a program is actually being proposed in San Francisco, modeled after the wildly-popular Berkeley FIRST.

Sea level to rise 5 meters in 300 years
- posted by Laura
A climate conference in Oxford concluded last week that whatever we can do to slow carbon emissions, it won't be enough to stop accelerated sea level rise. In fact, a German scientist who's widely regarded as one of the world's foremost experts on sea level rise, said his best guess was 1 meter this century (a lowball figure compared to the latest projections for California), and 5 meters in 300 years. Expect a lot of bleak climate news to be revealed over the next few months, as the world prepares for the U.N. climate change conference taking place in Copenhagen in December. The conference's web site is a great source of daily climate news from around the globe. And if you don't like what you see coming out of Copenhagen, try visiting Hopenhagen instead.
