GM Shows Off Their New 230mpg Chevy Volt Posted: 14 Aug 2009 06:14 AM PDT Plug-ins and electric cars are a core climate solution, since electric drives are more efficient, easily powered by carbon-free energy and indeed far cheaper to operate per mile than gasoline, even when running on renewable power. And they are the key alt-fuel strategy needed to deal with the energy/economic security threat of rising dependence on imported oil and the inevitably grim impacts of peak oil (see "Why electricity is the only alternative fuel that can lead to energy independence"). I think the Volt was overdesigned (see "CMU study suggests GM has wildly oversized the batteries in the Chevy Volt plug-in hybrid"), but very much hope it succeeds. Our guest blogger, Kate Tecku, Energy Policy Intern at the Center for American Progress, has the latest updates on the Vote (first posted here). See also "So what is it like to actually drive the Chevy Volt plug in hybrid electric car?"). On Tuesday, after weeks of buzz from a viral media blitz, GM finally answered its own marketing spin, "What is 230?" Apparently, the new Chevrolet Volt – set to hit show room floors in 2010 – will achieve an astounding city fuel economy of 230 miles per gallon. GM Chief Executive Officer Fritz Henderson exclaimed in a press release on Tuesday that the Volt is sure to be a "game changer." He went on to note that "based on the results of unofficial development testing of pre-production prototypes, the Volt has achieved 40 miles of electric-only, petroleum-free driving." This, taken in conjunction with the Department of Transportation's findings that nearly 8 in 10 Americans drive less than 40 miles per day, means that "many Chevy Volt drivers may be able to be in pure electric mode on a daily basis without having to use any gas" – unlike other hybrids such as the Toyota Prius. The Volt, however, could cost about $40,000, putting it out of reach of many middle income consumers. GM believes that government incentives and battery warranties can make this new PHEV model an appealing option to climate- and cost-conscious consumers, despite the Volt's high production costs. Prime among these government measures is a $7,500 consumer rebate in the 2009 stimulus package for purchasing qualifying electric plug-in vehicles such as the Volt. The Volt will become more economically attractive when oil and gasoline prices rise during the worldwide economic recovery. In contrast to their conservative predictions in 2008, the Energy Information Agency now expects oil prices to increase to $110 a barrel by 2015. Critics say the 230 mpg claim for GM's new plug-in is misleading – and even if it does live up to the hype, the Volt's fuel range will pale in comparison to Nissan's new plug-in model, the Leaf, due out in 2012. In a show of industry competition for most fuel economy supremacy, Nissan's EV Twitter feed posted this yesterday: "Nissan Leaf = 367 mpg, no tailpipe, and no gas required. Oh yeah, and it'll be affordable too." Japanese auto makers aren't the only competition GM will have in the PHEV market. China announced last December it's new plug-in, the F3DM, which will only cost an estimated $21,000 and has a battery range of an estimated 63 miles. Though it is unlikely that this model meets other U.S. safety standards, it is yet another sign that China wants to dominate the development and sale of clean energy technologies. General Motors hopes the release of the Volt will signal to consumers the company is heeding the call for a new generation of super fuel efficient vehicles. The Center for American Progress hosted auto industry executives and independent engineers back in 2008 at an event to discuss the future of plug-in electric technology where GM Vice President Jonathan J. Lauckner acknowledged that "the automobile industry can no longer exclusively rely on oil as fuel for our vehicles." GM and the Volt may notably affect the electric car battery industry as well. Bob Kruse, GM's executive director of global vehicle engineering, said on Friday that lithium-ion batteries – the kind that powers the Volt – are expected to come down in price and weight as the Volt is brought into mass production: "Getting the energy density up, getting the weight out, getting the cost out, that's all part of what we are going to be challenged to do," said Kruse. Efforts to design the long range batteries of the future got a boost on August 5th when President Obama announced at a speech in Elkhart County, Indiana that the Department of Energy would invest $2.4 billion in advanced battery research. The funding is from the American Recovery and Reinvestment Act, and is expected to save or create tens of thousands of jobs in Indiana. In addition, investments in a new smart grid will also be pivotal to the full scale deployment of PHEV's. Britta Gross, General Motors' manager of Hydrogen and Electrical Infrastructure Development spoke at length in an interview last November about the partnerships GM has built with utility companies such as Duke and Edison and her confidence that these companies are more than prepared for the wide-scale deployment of the Volt. This announcement by GM is sure to please the White House, considering then-candidate Obama's pledge last August to put 1,000,000 plug-in hybrid vehicles on the road by 2015. The Volt and other super efficient cars are an essential element to meet President Obama's new fuel efficiency standards that the White House believes will "result in savings of 1.8 billion barrels of oil over the lifetime of vehicles sold in the next five years alone." Plug-in vehicles like the Volt are essential to cutting our nation's addiction to foreign oil and reducing global warming pollution. It may just be the "game changer" GM – and America — needs.

Posted: 13 Aug 2009 07:02 PM PDT A BBC story on the new study, "The spatial and temporal evolution of Pine Island Glacier thinning, 1995 – 2006," (subs. req'd) explains:
When we last left Antarctic research, it turned out that the great ice sheet's temperature had risen by up to about 3°C (5.4 °F) in the past 50 years, which is the fastest increase in the southern hemisphere (see "Antarctica has warmed significantly over past 50 years, revisited"): Antarctica is disintegrating much faster than almost anybody imagined. In 2001, the IPCC "consensus" said neither Greenland nor Antarctica would lose significant mass by 2100. They both already are. As Penn State climatologist Richard Alley said in March 2006, the ice sheets appear to be shrinking "100 years ahead of schedule."
The rest of this post will survey what we now know about the increasingly unstable West Antarctic ice sheet (WAIS) and the threat it poses to humanity — or is that the threat humanity poses to it? — if we continue on our current suicidal emissions path. Regular readers can skip the rest of this post since I'm mostly excerpting, "Q: How much can West Antarctica plausibly contribute to sea level rise by 2100?" [A: 3 to 5 feet]. A 2007 study found "The current loss of mass from the Amundsen Sea embayment of the West Antarctic ice sheet [WAIS] is equivalent to that from the entire Greenland ice sheet" (see the new survey report Antarctic Climate Change and the Environment draft here). And WAIS's 2007's ice loss was 75% higher than 2006's (see "The Antarctic ice sheet hits the fan"). The warming of the WAIS is most worrisome (at least for this century) because it's going to disintegrate long before the East Antarctic Ice Sheet does — since WAIS appears to be melting from underneath (i.e. the water is warming, too), and since, as I wrote in the "high water" part of my book, the WAIS is inherently less stable:
You can read every thing a laymen could possibly want to know about what the recent study on Antarctic warming does and doesn't show at RealClimate here. A couple of new papers published by Nature in March have been portrayed as suggesting the WAIS as a whole may be stabler than was previously thought. Yet the first paper, "Obliquity-paced Pliocene West Antarctic ice sheet oscillations" (subs. req'), concludes:
We'll be at 400 ppm by 2020. We're on track to be more than 5°C warmer by 2100. So the first paper doesn't seem terribly reassuring. The second paper by Pollard and DeConto (the one that got all the attention), "Modelling West Antarctic ice sheet growth and collapse through the past five million years," (subs. req'), notes, "Recent melt rates under small Antarctic ice shelves are inferred to be increasing dramatically" and concluded:
Are you reassured yet? I would note that West Antarctica land temperatures have risen up to 3°C over the past 50 years — some 4 times what the planet as a whole has warmed. And both Hadley and MIT say the planet will warm more than 5°C by 2100, with a 10% chance of warming more than 7°C (see M.I.T. doubles its projection of global warming by 2100 to 5.1°C and "Hadley Center warns of "Catastrophic" 5-7°C warming by 2100 on current emissions path. And while the ocean warms less than the nearby land, the new study Antarctic Climate Change and the Environment warns: "UP TO one-third of all Antarctic sea ice is likely to melt by the end of the century." So we may yet see polar amplifacation near the South Pole (see "What exactly is polar amplification and why does it matter?"). Dr. Robert Bindschadler of NASA, who has been an active Antarctic field researcher for the past 25 years, commented on the new study (here):
Moreover, the entire WAIS need not collapse for it to contribute to catastrophic sea level rise this century. The Antarctic Peninsula alone contains "a total volume of 95,200 km3 (equivalent to 242 mm of sea-level; Pritchard and Vaughan, 2007), roughly half that of all glaciers and ice caps outside of either Greenland or Antarctica" (see Chapter 5 here) — that would be more than 9 inches of sea level rise from a region of WAIS losing its protective ice shelves on both sides at an alarming pace. But it is westernmost part of WAIS, that borders on the Amundsen Sea, and that includes Pine Island, that we need to worry most about, as AP reported earlier this year:
So we have the serious potential for 3 to 5 feet of sea level rise just from WAIS this century — and that is on top of whatever we get from thermal expansion of the ocean and Greenland. And on top of whatever we get from the melting of the inland glaciers, whose contribution was recently increased:
So it increasingly looks like we are facing a very serious risk of more than 5 feet of total sea level rise by 2100 on our current emissions path. But this is almost not news anymore — see Startling new sea level rise research: "Most likely" 0.8 to 2.0 meters by 2100. Indeed, an important Science article from 2007 used empirical data from last century to project that sea levels could be up to 5 feet higher in 2100 and rising 6 inches a decade (see Inundated with Information on Sea Level Rise. Another 2007 study from Nature Geoscience came to the same conclusion (see "Sea levels may rise 5 feet by 2100"). Leading experts in the field have a similar view (see "Amazing AP article on sea level rise" and "Report from AGU meeting: One meter sea level rise by 2100 "very likely" even if warming stops?"). Even a major report signed off on by the Bush administration itself was forced to concede that the IPCC numbers are simply too out of date to be quoted anymore (see US Geological Survey stunner: Sea-level rise in 2100 will likely "substantially exceed" IPCC projections). Did I mention the time to act is now! Related Posts:

NASA: Second hottest July on record Posted: 13 Aug 2009 12:44 PM PDT Fast on the heels of the second hottest June on record, NASA's Goddard Institute for Space Studies reports that July is also the second hottest on record. NASA just quietly updates its data set (here). NASS GISS is much more low-key than NOAA's National Climatic Data Center, which issues a major report on the climate every month (see NCDC: Second hottest June on record — and once El Nino really kicks in, expect global temperatures "to threaten previous record highs"). I'll wait for that report (out in a few days) for a longer discussion of July. What I think is interesting about the NASA month-by-month data is that you can compare it to El Niño-Southern Oscillation (ENSO) data and see that it typically takes 3 to 6 months before an El Niño seriously starts warming up the whole planet (see page 24 here). So we have a ways to go before we see the full effect of this El Niño. Still it's interesting that the NCDC reported that the ocean temperature in June was the warmest on record — a full 0.11°F warmer than the 2005 record. This certainly looks to be the new El Niño on top of the long-term warming trend. If indeed this is a moderate to strong El Niño, then it looks like we will be seeing record global temperatures this year or next, as NASA predicted back in January (see here). |
