Creeping Along Toward New Fuel Standards

Photo: Craig Miller

This week, California and federal regulators gave themselves a fall deadline in their collaboration to create national fuel economy and greenhouse gas standards for model year 2017-2025 cars and light trucks.  The agencies say they will propose the new standards by September 1, 2011.

The September deadline is something of a setback for California, which had planned to release state standards in March.

Last October, the federal EPA and Department of Transportation announced plans to work with California Air Resources Board (CARB) to create the standards, under direction from the Obama Administration.   This builds on the agencies’ work setting the  new federal fuel standard, based on California’s, for model years 2012 through 2016.

According to a statement from CARB, a unified state/national standard will “provide manufacturers with with the regulatory certainty needed to invest today in the kind of new technologies that will provide consumers a full range of efficient clean vehicle choices.”

Death Rattle of an Iceberg

I know it’s only January but my vote for the year’s Really Cool Sound Award: A  massive iceberg cracks up.

Occasional Climate Watch contributor Tom Banse reports today for Oregon Pubic Broadcasting about a just-released recording of a massive iceberg cracking, creaking, snapping, and groaning as it broke up in 2005 off the coast of Antarctica.  The recording has been condensed, so that you can listen to the five-hour process in just two minutes.

According to Seeyle Martin, the University of Washington scientist who released the recording, the iceberg was 76 miles long and 17 miles wide — about the size of Puget Sound. It shattered when it hit an underwater shoal.  Martin says the sound was recorded by seismic equipment 700 miles away at the South Pole.

Climate Warms, Trees Head Downhill?

As the climate warms, plants and animals will need to move uphill to more hospitable climes, right?  Some are — but it turns out that in other cases, the process seems to have shifted into reverse.

According to a new study published in the journal Science, some plants in Northern California are actually moving downhill in response to climate change.   Aided by historical data, researchers from UC Davis and the University of Montana determined that between 1930 and 2000, many California species shifted downward an average of 260 feet.

The reason, according to UC Remote Sensing scientist Jonathan Greenberg, is increased precipitation, which, in some cases is overriding temperature as the main driver for species distribution.

“These wetter conditions are allowing plants to exist in warmer locations than they were previously capable of,” said Greenberg in a press release about the study.

NPR’s Richard Harris has more on the study and on what it could signal for California’s changing ecosystems.

Photos From the Future?

From my vantage point this morning at the edge of San Francisco Bay at China Camp State Park in San Rafael, today’s king tide wasn’t all that dramatic.  There was no flooded road, as I had been told there might be, and there was so little wind that the water level just silently crept higher, about a foot higher than usual, with zero fanfare.

But I snapped photos anyway, for the Bay Area King Tide Photo Initiative, a project aimed at documenting these extreme high tides in order to identify local areas vulnerable to sea level rise.

Reportedly, things at San Francisco’s Embarcadero, however, were a little more dramatic. USGS scientist Noah Knowles was there to take pictures of yesterday’s king tide.

“There was already water splashing over the sides [of the sea wall] yesterday,” he said.  “This was of course on a very calm day, and clearly there was no storm surge, which could have added another half-meter and had the water up on the streets.”

That’s the thing about sea level rise.  The San Francisco Bay Conservation and Development Commission (BCDC)  advises people to plan for 11-18 inches of sea level rise by mid-century.  That by itself might not cause huge amounts of damage on a normal day, just as today’s extra-high tide didn’t flood the road in China Camp State Park.  What it will do, however, is raise the baseline for what a high tide is, making storm surges more apt to cause destructive flooding.

Knowles said that it’s important to raise awareness about what the potential effects of sea level rise could mean for the Bay Area.

“I think it doesn’t always hit home how low-lying so many area around the Bay already are,” said Knowles.

King Tides Could Preview Sea Level Rise

This week, seasonal high tides, known as “King Tides” will roll into the Bay Area, providing a preview of what the region might face if sea level rises over the coming decades as predicted.

So the organizers of the Bay Area King Tide Photo Initiative want you to grab your camera and help document the tides.  The San Francisco Bay National Estuarine Research Reserve (NERR) has set up a Flickr site for the photos, where participants can upload their “before, during, and after” shots.

Planning for the Other “Big One”

Imagine 45 days of rain brought by a series of winter storms so strong and wet that they turned the Sacramento Valley into an inland sea, making the state capital virtually inaccessible.

Well, that happened in California in the winter of 1861-1862, and scientists say it will happen again, bringing massive flooding, landslides and property damage across the state.

To help emergency agencies plan for such an event, the US Geological Survey released the “ARkStorm Scenario” in Sacramento this week, detailing the repercussions of a storm that produces up to ten feet of rain and forces the evacuations of more than a million people.

“Vast floods would basically take out all the farm land,” said Marcia McNutt, director of the USGS. “They would destroy homes, animals would die, roads would be impassable, infrastructure would be rendered unusable, dikes would fail, levees, would fail.”

Scientists created this hypothetical storm by combining two actual storms, one from 1969 and one from 1986, and putting them back to back.  Together, they rival the 1860’s storm in magnitude, which was the last time California saw a storm this size.

Its First Renewables Goal Unmet, Can CA Meet The Next One?

3 Comments

California may not have met its goal of 20% renewable energy by 2010, but outgoing California Energy commissioner Jeffrey Byron says the state is close, and that California is on track to meet its its goal of 33% renewable energy by 2020.

“We didn’t get to the point where we’re generating 20% of our electricity by renewables, but I believe we do have, or we’re very close to having, all the contracts in place,” he said Thursday.

Byron was at Stanford University on Thursday, speaking at a workshop titled, “Grid Integration of Renewables.”

Another One Bites the Dust?

California’s cap-and-trade partners are dropping like flies.

It’s not official yet, but it’s looking like what was once envisioned as a regional carbon trading program involving seven US states and four Canadian provinces, will now involve just one US state – California – and just three provinces: Quebec, British Columbia, and Ontario.

One by one, members of the Western Climate Initiative have postponed their involvement or dropped out altogether, as Arizona did last February when Gov. Jan Brewer issued an executive order backing out of the carbon trading program.

And today, an online publisher quotes a key official in California’s carbon trading program, that the state stands to lose its last remaining US partner, New Mexico. As Colin Sullivan of E&E reported:

Kevin Kennedy, assistant executive officer in charge of the Office of Climate Change at the California Air Resources Board, told lawyers during a forum sponsored by Law Seminars International that the election results likely mean New Mexico will not participate in the fledgling WCI, at least at the outset of the market starting Jan. 1, 2012.

“The change in administration probably takes New Mexico out of the situation,” Kennedy said.

Last week New Mexico’s new governor, Susana Martinez, announced that she was removing all members of the state’s Environmental Improvement Board, “because of what she said was its ‘anti-business’ policies.”  Last year, the EIB approved measures for the state to limit emissions and join the WCI’s cap-and-trade program.

Reporting on climate change sinks to its lowest level since 2005

When Al Gore lamented recently in the Huffington Post that “the media has failed to appropriately cover the climate crisis,” he was talking about the relatively small amount of science that made it into reporting about the 2009 climate conference in Copenhagen.

But it looks like in 2010, the issue wasn’t so much a lack of science in the reporting, as the lack of reporting in general.  An analysis by the Daily Climate that’s been making the rounds, finds that in 2010 coverage among major media outlets of climate change dropped to its lowest level since 2005.  Between 2009 and 2010, it dropped 30%, according to the Daily Climate tally.
