Global warming ‘irreversible’ for next 1000 years.

As reported by AFP, NOAA (National Oceanographic and Atmospheric Administration) scientists have released a study saying that current levels of global warming will cause irreversible damage, no matter what is done in the future to decrease CO2 and other related emissions.  I will add a link to the primary scientific article when the link is published.

“NOAA senior scientist Susan Solomon said the study, published in this week’s Proceedings of the National Academy of Sciences journal, showed that current human choices on carbon dioxide emissions are set to “irreversibly change the planet.” Researchers examined the consequences of CO2 building up beyond present-day concentrations of 385 parts per million, and then completely stopping emissions after the peak. Before the industrial age CO2 in Earth’s atmosphere amounted to only 280 parts per million. The study found that CO2 levels are irreversibly impacting climate change, which will contribute to global sea level rise and rainfall changes in certain regions. The authors emphasized that increases in CO2 that occur from 2000 to 2100 are set to “lock in” a sea level rise over the next 1,000 years.”

This is certainly well past a wake-up call, if anybody still needed one. Here’s where the relentless optimist meets the original cynic: I refuse to accept that it is worthless to make the biggest changes possible to head off increased global warming. Am I denying science? No, I’m just clinging to hope.

Please see the article by Sam Carana on how a larger grid, yet a simultaneously more locally-run grid, can be implemented.  The purpose is to capture as much of the electricity being generated as possible while keeping a local level of control, to try to avoid undue influence by those who fail to understand the details of energy policy.  Read about how many parts of Europe already have surplus electricity, and how countries are linking their grids together to improve efficiency.  Part of the rationale for such arrangements in Europe is that countries which generate a lot of electricity from wind can necessarily control when that electricity is most plentiful, but they don’t want it wasted.  At the same time, such European countries may need electricity from other sources, say hydroelectric plants in a neighboring country, when wind power isn’t sufficient.  Similar arrangements could be made throughout North America.  See what Sam has to say!  He gives lots of sources for his comments and information.

Asbestos is still imported and used in the U.S. According to the U.S. Geological Survey, the U.S. imported and used an estimated 1,820 tons of asbestos in 2007; see this PDF file from the USGS, please click only if you want to download the PDF. Also, the U.S. House of Representatives is considering a bill H.R. 6903 The Bruce Vento Ban Asbestos and Prevent Mesothelioma Act to ban the future importation and use of asbestos (it is already banned in 40 countries) and provide funding for medical research into effective treatments for asbestos-related diseases. Also, around the 2007 Christmas season, the Asbestos Disease Awareness Organization had some household products, such as duct tape, and toys tested and found they contained asbestos. See Ban Asbestos.

The processing of fossil fuels has a long trail of consequences, with some being more obvious than others. There are essentially two tiers of negative ramifications to backwards energy policies. The first of these are the direct environmental consequences of the burning of fossil, which has been well documented in recent years with the recent interest in the effects of global warming. However, the second tier are the human health effects associated with the burning of fossil fuels.

(Revised Editor’s note: this paragraph has been removed.  Some comments refer to the missing text).

Then there are the more indirect costs, and specifically those which are associated with the industry itself. Working conditions in the fossil fuel industry are among the most hazardous of any occupation. One of the hazards workers will encounter is asbestos, which has been classified by the Environmental Protection Agency and the Consumer Product Safety Commission as a known carcinogen. And even though asbestos was banned by the CPSC in the late 1970’s, older asbestos fixtures still exist within nearly all facets of the fossil fuel infrastructure. These older and sometimes damaged fixtures pose and even greater hazard to human health.

When microscopic asbestos fibers are inhaled, they lodge themselves in the lining of lungs. This lays the groundwork for the deadly asbestos cancer, mesothelioma. Perhaps it should come as no coincidence then that rates of pleural cancer (mesothelioma) in oil refinery workers are among the highest of any occupation.

What we begin to see then, is that there are effects of ozone depletion and fossil fuel use and processing, that are detrimental not only to the planet, but also to human health. When the world opens its eyes to the crisis we’re supporting, we’ll not only have sustained the future for our children, but also saved lives.

As reported by Ken Thomas of the Associated Press (AP), the Chevrolet Equinox has been delivered to people participating in a trial program that involves free loans of the innovative vehicles to a small group of consumers. In addition to General Motors, Honda and BMW are supplying hydrogen fuel cell-powered cars for initial trials in real-life driving conditions. The AP report is summarized here, with additional information provided (links to sources are given).

The Chevy Equinox carries up to 4 kilograms (8.8 pounds) of hydrogen gas in pressurized tanks. In the fuel cell, hydrogen reacts with oxygen to generate electricity and the byproduct, water. Although explosive under some conditions, hydrogen is considered safe in these cars because a leak in the system would simply cause the hydrogen to become diluted by air, reaching concentrations that aren’t flammable. Equinox driver Tom Albert has covered 2300 miles in two months, and is enthusiastic about the car, citing only the lack of filling stations and the 200 mile range as real limitations (there are only two filling stations in the Washington, D.C. area where he lives).

Reportedly, the performance of the Equinox is equivalent to approximately 43 miles per gallon with conventional gasoline. The cars themselves are considered to be zero emission vehicles, though the source of hydrogen affects the ultimate environmental impact of this technology. Currently, most hydrogen comes from fossil fuels in a process that does generate CO2. However, the goal is to generate hydrogen from renewable sources. One approach to sustainable hydrogen was recently described here and republished here with additional discussion. In addition, as reported by Thomas, extracting hydrogen from natural gas results in about half the CO2 production associated with equivalent gasoline use by a vehicle. This information comes from Patrick Serfass, director of technology for the National Hydrogen Association.

There is a Federal Government target of producing hydrogen at a cost equivalent to $1.50/gallon of gasoline by 2010; current costs are estimated to be $3.00/gallon.

The Chevy Equinox is joined by the Honda FCX Clarity, which is being leased for $600/month to about 200 people in California. There were 50,000 web-based requests for leases, but the program was limited in part by the location of filling stations. Of the 61 hydrogen fueling stations in the U.S., about half are in California. A press release from Air Products, a major supplier of hydrogen, provides more information about present and future health of hydrogen as fuel.

The FCX Clarity travels about 270 miles on one tank of hydrogen, and Jon Spallino is one happy driver:

You’re not sacrificing anything, and actually for me it’s an enhanced driving experience… I think that’s a misconception people have, that you’re puttering around in an underpowered cramped little soapbox

BMW’s Hydrogen 7 runs on gasoline or hydrogen, with separate tanks to take you about 130 miles on hydrogen and 300 miles on gas.

So far, the production of fuel cell cars requires custom manufacturing, so the real costs per car are very high and undisclosed, but things are certainly being driven in the right direction.

Green issues are sometimes complex.  We need to recycle many things, like electronics, but we certainly don’t want to poison others in the process.  Efforts to protect the environment and conserve valuable resources must be coupled with proper health and safety procedures.  Unfortunately, just saying this doesn’t make it happen.  Developing countries are becoming a dumping ground for much toxic waste and proper environmental health and safety is being ignored, both by local opportunists and suppliers of e-Waste from developed nations.  From Greenpeace:

This shocking documentary from Greenpeace shows how “second hand goods” exported to Ghana for reuse are actually causing horrendous pollution. “People in the developed countries bring them here to bridge the digital gap but in actual fact they are creating a digital dump.”

Ghana — The latest place where we have discovered high tech toxic trash causing horrendous pollution is in Ghana. Our analysis of samples taken from two electronic waste (e-waste) scrap yards in Ghana has revealed severe contamination with hazardous chemicals.

Similar problems occur in China and, surprisingly, even in developed countries.  See related information about toxic waste dumps all over the world here.

However, you can also read good news about environmental protection in Europe and the effect it is having on US companies.

Originally published in a somewhat different form on my Squidoo solar power lens and Sustainability group. Please note that Sam Carana has written a lot about the hydrogen economy, and he covered this same story, but with more technical information about the new science and catalysts, here.

Hydrogen and oxygen gases can be used in fuel cell technology to provide energy to a home, and these gases can be produced by the action of electricity on water. Hydrolysis can also be carried out by the action of sunlight on water, with the help of certain types of solar cells, or photovoltaics. Electrolysis often requires caustic conditions, or high pH (or a lot of electricity is wasted), but the caustic requirements, and most wasted electricity, can be overcome with the use of additional components known as catalysts. The result is that solar energy can be used to power a home during the day by generating electricity, and consumers would have a variety of options to store excess electricity:

Batteries are typically thought of for storage of electricity, but another option is offered by the power of sunlight: energy storage through generation of hydrogen and oxygen by electrolysis. Gernation of hydrogen and oxygen under acceptable and convenient conditions has become just more possible with the discovery of a new, breakthrough catalyst for electrolysis:

As described by Mariella Moon of ExtremeTech, “… one catalyst would be responsible for producing oxygen gas from water, while another would produce hydrogen. The hydrogen and oxygen could be recombined in a fuel cell to power the home at night where solar energy isn’t readily available…”

Hydrogen and oxygen would accumulate during the day from excess electricity generating capacity of a solar cell system, and then these gases would serve as the fuel for a fuel cell that would power a house overnight. The byproduct of the fuel cell, water, could then be re-used for water splitting (electrolysis) the next day.

Illustrations of the idea and video from principle scientist D. Nocera of MIT is shown at the GoodCleanTech site, the Green Blog of, as posted by Mariella Moon.

The key to the new catalyst for electrolysis is that, unlike the catalytic converter in your car, it does not require expensive metals like platinum or rhodium, yet it works at atmospheric pressure, room temperature and moderate pH, thus providing hydrogen and oxygen that can feed a fuel cell with minimal environmental impact.

For both laptop and desktop computers, Dell plans to cut power consumption as part of its required work on compliance with the EPA’s EnergyStar 5.0 standard, reports Mark Hachman of HP earlier said it would cut power use of “volume” PCs by 25 percent, relative to 2005. In those terms, Dell’s reductions would be 62 % for desktops, 37 % for laptops (says Dell’s Albert Esser, vice president of power and infrastructure solutions). These changes are of course very welcome.

“One, we will first continue to integrate Energy Smart technologies into the product,” Esser said, referring to a basket of Dell technologies that includes low-power Intel and AMD processors, aggressively power-managed system settings, and management tools. Those will also include circuit design and internal routing, he said.

“Low-flow fan technology is a significant one,” Esser added. ‘We don’t source the cheapest…fans, but often we choose to work with a vendor to create a custom design.”

Dell also plans to use higher-effficiency power supplies from the organization 80 PLUS (certified 80% efficient), though even more efficient power supplies (85%) are required by EnergyStar 5.0, from what I have already read and reported.

It is worth noting that proposed European are much more stringent than US EPA standards on toxic components of PCs.

Toyota, as reported by Jamie Lendino of ExtremeTech, has the most fuel efficient line of cars in the US, with an average of 29.7 mpg for actual vehicles sold. Results are based on the 2007 model year. Discussion in the forum goes into upcoming offerings from Honda and VW, but they have to be taken with a grain of salt until we can buy them! Kudos to Toyota for delivering on the showroom floor.

Honda and Hyundai were next on the list with 29.47 and 29.39, respectively. Domestic brands were much further down the list, with GM, Ford, and Chrysler scoring 25.16, 25.15 and 23.97—evidence of product line-ups that are more heavily weighted on the truck and SUV side of the equation.

Yahoo Autos and Road & Track Magazine have provided “spy” photographs (by Brenda Priddy & Company) and a very preliminary description of the new Honda Hybrid, a 2010 model destined to reach dealers in late 2009. While details of the gasoline engine side of the car have not yet been disclosed, the electric side is reportedly based on a nickel/metal-hydride battery design rather than a lithium-ion battery. Gas mileage is thought by Road & Track to be “class leading” and well above 40 mpg. Author Sam Mitani says:

The price of this new car will be low, as Honda maintains it will be an entry-level car with 200,000 units selling annually — half of those to be sold in the United States. Early rumors indicate that it may be as low as $19,000. With seating for five, this 4-door, front-wheel-drive hatchback…

Although exactly where this car will fit into the Honda line is unknown to outsiders, the new Honda hybrid will compete with the Toyota Prius:

Whichever label it wears, one thing for sure is that the new Honda Hybrid will be one of the most fuel-efficient vehicles in the world, and may wrest the crown away from the Prius as the world’s favorite green car.

The appearance of another hybrid in the U.S. and world markets is certainly a cause for celebration, though my loudest cheers will be for the plug-in hybrids that will (or should) also be arriving soon.
