Obama Equals More than 2C of Global Warming

The night Barack Obama was declared the winner over John McCain in the presidential election of 2008 there were probably many sighs of relief by environmentalists who were sure there would finally be a science-based policy to deal with climate change. And when Obama later appointed his chief science adviser and Secretary of Energy that must have seemed like confirmation. But now that Obama has served as president for more than three years most of the sighs of relief have probably turned into cries of frustration. Not only is there no science-based policy (e.g., reducing emissions by 25-40% below 1990 levels by 2020 in developed countries) but Obama rarely even mentions the climate crisis. Moreover, he boasts of increased oil drilling as if he ran on the crazy drill-baby-drill platform of the Republicans. Where is the man we elected who promised to deal with global warming and was advocating a cap and trade program to help accomplish the goal?

According to the International Energy Agency (IEA), the nations of the world must begin stringent action before 2017 to have any reasonable chance of keeping the warming to less than 2C, considered by many climate scientists the threshold for dangerous climate change (although many others say the threshold may be even lower). The IEA says that so many fossil fuel power plants and industrial facilities will be built by 2017 that it will be virtually impossible to stay below 2C if the type of action needed has not been started by then. But Obama has agreed with other countries not to start legally binding action until 2020 and the nature of the action has not been specified, it might not include reducing emissions. It therefore appears that regardless of whether Obama is re-elected in the upcoming presidential election or his Republican opponent the world will probably experience dangerous climate change in the not too distant future. What a choice!

Shrink the Economy to Fight Global Warming Says Author of “Losing Our Cool”

How many times have we heard Al Gore, Thomas Friedman, and others say that unleashing green technology to fight global warming will also drive economic growth? But is economic growth really compatible with fighting global warming? No it isn’t says Stan Cox, the author of a new book entitled “Losing Our Cool: Uncomfortable Truths about Our Air-Conditioned World (and Finding New Ways to Get Through the Summer).” In an interview posted on Grist he cites a paper by an economics professor at the University of Utah which concluded that to keep atmospheric carbon dioxide below 450 ppm, considered by many scientists as the threshold for dangerous climate change, “the world economy is going to have to shrink by 1 to 4 percent per year over the next 40 years.” If that isn't bad enough news for consumption-obsessed societies he also says that we will need “a pretty massive transfer of wealth from wealthy individuals, areas, or countries to those that are less wealthy. When you say we have to reduce the output of the economy by so much each year, there are many, many people in the world that have nothing to reduce. They actually need a bit more production just to get the basic necessities of life.” That’s probably not going to go over too big in Tea Party circles or in the executive suites of major corporations.

A similar conclusion about the need to shrink the economy was reached in a study by the Tyndall Centre for Climate Change Research in Britain. The study called for a reduction in living standards in the wealthier countries over the next 10 to 15 years.

Cox says that a different economic system is required. He also admits that “Unfortunately I'm not, and I'm not sure who is, smart enough to know how to get out of our situation.”

It seems our best hope is that these studies that call for a shrinking economy, a redistribution of wealth within countries and among countries, and even the end of capitalism are wrong. It seems impossible to imagine such radical change taking place within the next few years, which is when it would have to occur to be effective. Right or wrong it should be a topic of discussion in the mainstream press but even that seems too much to ask for.

India Moves into Third Place among Greenhouse Gas Polluters

India has a long way to go to catch up to China and the US when it comes to greenhouse gas emissions but it has finally passed Russia on the list taking over third position. At the moment India only accounts for 3% to 5% of emissions compared with 23% and 22% for China and the US, respectively, but with its huge and growing population and rapidly growing economy it is bound to close the gap with at least the US over the coming years. As it is, India, China, and the US account for about half of all emissions and this proportion will grow as India and China keep lifting people out of poverty and having such people adopt a much more energy hungry Western type of lifestyle.
Those who say that these three countries should get together and come to an agreement on limiting greenhouse gas emissions instead of relying on the UN process which requires that almost two hundred countries arrive at an agreement seem to make more and more sense as the UN process appears to be getting nowhere. The UN meeting in Cancun, Mexico in a couple of months should provide more information about whether or not the UN process should be abandoned. A more or less complete failure should be a signal that a new type of process is needed.

Copenhagen Accord Pledges Add Up to Climate Catastrophe

If anyone believed that the leading global warming polluters would have an epiphany and pledge greenhouse gas emissions reductions that would save us from climate catastrophe they must be sorely disappointed. Fifty-five countries met the deadline of January 31 to pledge for the hastily drawn up Copenhagen Accord and did exactly what they said they would do, which is nowhere near enough to avoid having the global temperature soar beyond the ominous 2C mark above preindustrial levels. An Associated Press article reports that the US stuck to its miserly pledge of 17% reduction below 2005 levels by 2020 and the biggest global warming polluter of all, China, will not pledge to reduce emissions but only to reduce emissions growth. Of course, these pledges are not legally binding so not only are they insufficient but may never be adhered to. So it looks like just about everyone is resigned to go over the climate cliff together. What does that say about human intelligence? Somehow it doesn’t translate into sane actions on a national level. It looks like mass stupidity has triumphed after all. Who would have guessed that millions of years of evolution would lead to that?

Australia Overtakes the US as Leader in CO2 Emissions per Person

After being recently replaced by China as the number one greenhouse gas polluter in the world, the US has now been surpassed by Australia as the leading nation in CO2 emissions on a per capita basis. According to Reuters, the US emissions of 19.8 tons per capita annually was only good for second place, with Australia taking over the lead with 20.6 tons. In third place was Canada at 18.8 tons. Per capita emissions have become a major sticking point in the negotiations on a climate treaty to replace the Kyoto Protocol which expires in 2012 as developing countries, particularly China and India, have been arguing that developed countries should assume most of the burden for reducing emissions since on a per capita basis their emissions are several times higher. However, the British economist Nicholas Stern, who wrote an influential report on climate change, recently noted in a talk given in Beijing, China, that although China’s emissions on a per capita basis are much lower than those of developed countries, there were 13 provinces, regions, and cities in China that actually had higher emissions per capita than France and 6 with higher emissions than Britain. According to the AFP news agency, Stern has calculated that for the risk of dangerous climate change to be minimized emissions would need to be reduced to 2 tons per person worldwide. Unfortunately, with millions of people in China and India rapidly adopting Western lifestyles and many developed countries including the US refusing to commit to the necessary reductions in carbon dioxide emissions by 2020 called for by the leading climate scientists the prospects for minimizing the risks of dangerous climate change appear to be rapidly diminishing.

Indian Environment Minister Says Westerners Need to Live with Only One Car Not Three

With the countdown to the UN’s climate meeting in Copenhagen reaching the 100-day mark yesterday India’s environment minister, Jairam Ramesh, gave a speech in Delhi in which he reiterated that India will not agree to a target for reducing greenhouse gas emissions. According to an article in The Guardian, Ramesh said that “For us this is about survival. We need to put electricity into people’s homes and do it cleanly. You in the west need to live with only one car rather than three. For you it is about luxury.” Luxury? Wait a minute! Perhaps if Ramesh has a family with a teenage driver he should rent a McMansion in one of our cul-de-sac suburban developments for awhile and try to live with one car. Good luck! He would quickly find out that to get to anything other than a nearby neighbor’s house that he would have to drive. If he takes the car to work his wife would be either stranded at home all day or unable to get to her job. If the teenage driver takes the car to see a friend in the evening or on weekends they would both be stranded at home. Ramesh would quickly come to realize that two cars are a necessity and even having that third car avoids a lot of conflicts. These houses don’t have three-car garages for nothing. To really change things Ramesh would have go back in time to the 1950s and stop our government from building the interstate highway system and subsidizing mortgages through the GI bill. In other words, he would have to stop the things that made building our sprawling suburbs possible. We can’t now in 2009 turn back time. “The die has been cast.” If Ramesh and India are waiting for us to go from three cars to one car it promises to be a very long wait.

Phase-out of “Super” Greenhouse Gases Through the Montreal Protocol Might Limit Climate Change

A report by the non-profit Environmental Investigation Agency (EIA) says that using the Montreal Protocol ozone treaty to phase out hydrofluorocarbons (HFCs), chemicals that are now being used in refrigerators and air conditioners as a substitute for chemicals that are responsible for the ozone hole, could be a major step in the fight against global warming. In an article from the Inter Press Service News Agency, a senior U.S. climate campaigner from EIA is quoted as saying that “An HFC phase-down under the Montreal Protocol will do far more for climate protection than the Kyoto Protocol has accomplished in its entire history or than Copenhagen will achieve in the next decade.” The HCFs are called “super” greenhouse gases because these molecules can trap hundreds or thousands of times more heat than carbon dioxide. Phasing out HFCs is particularly important when considering projections of increased use of refrigerators and air conditioners in China and India between now and the year 2050. According to the EIA report, phasing out HFCs by 2050 would be the same as preventing from 118 to 224 billion tons of carbon dioxide being released. The G8 countries have made a commitment to phase-down HFCs. The members of the Montreal treaty next meet in November. So even with all the controversy over climate legislation in the U.S. and the bleak outlook for a global agreement on reducing greenhouse gas emissions in Copenhagen maybe progress will still be made toward limiting climate change before it is too late.

Gadget Happy Consumers Threaten Greenhouse Gas Targets

It looks like we may be Twittering and I-Phoning our way out of a chance to limit global warming. The addiction to being connected and entertained via electronic devices on a 24/7 basis has been increasing the consumption of energy around the world just as the need to reduce energy consumption has become critical to the goals of reducing greenhouse gas emissions. An article in The Guardian says that a study by the International Energy Agency forecasts that the total energy consumed by information, communication, and consumer technologies will triple in only two decades. By the end of this year it is expected that there will be 1,000,000,000 personal computers in the world. As computers continue to advance with more powerful processors, greater memory capacity, etc. they require more energy. There are nearly 2,000,000,000 televisions in the world and the new large plasma-screen TVs are particularly energy hungry. Wind turbines and solar panels will not be able to replace fossil fuels if energy demand keeps rising. The conclusion seems inescapable that the digital lifestyle is on a collision course with nature. The Director of the International Energy Agency, Nobuo Tanaka, is quoted as saying “Despite anticipated improvements in the efficiency of electronic devices, these savings are likely to be overshadowed by the rising demand for technology.” In other words, if we want to have a habitable planet maybe we should consider going back to reading books, listening to the radio, and talking on a corded phone. Okay, that may sound somewhat boring but it beats extinction any day of the week.

Plans for New UN Climate Agreement Lack Ambitious Targets for Reducing Emissions

If anyone expects that the Kyoto Protocol will be replaced by a new UN climate agreement that finally addresses what climate scientists say needs to be done to avoid a climate catastrophe it looks like they will be sorely disappointed. Reuters has analyzed plans submitted by developed nations for a new pact and the targets for greenhouse gas emissions reductions are not much stronger than the tepid ones of the Kyoto Protocol. Reuters concluded that the cuts called for range from 9 to 16 percent below 1990 levels by 2020. The Kyoto Protocol calls for a 5 percent reduction in emissions from developed countries by 2012. What do the climate scientists say is needed? According to the 2007 report of the UN’s Intergovernmental Panel on Climate Change (IPCC) emissions reductions of 25 to 40 percent below 1990 levels are needed by 2020. The cuts may even need to be steeper based on emissions data obtained after the report was released. For all the pronouncements we have heard from leaders of the developed countries that global warming needs to be finally addressed based on scientific knowledge none of them apparently are willing to do it. Perhaps at the final hour the leaders of the developed countries will face the facts and finally do what is needed but right now it seems far more likely that they will postpone taking the necessary steps even though postponement may almost guarantee future disaster.

Carbon Dioxide Increasing at a Record Rate in the Arctic

Measurements of atmospheric CO2 levels in northern Norway show that last week the levels hit a peak of over 397 parts per million (ppm). What was even more alarming than the actual level was the rate of increase because compared with the 2008 peak level the increase was more than 2.5 ppm. Professor of Atmospheric Physics at the Norwegian Polar Institute, Johan Strom, told The Guardian that “It is not the level of CO2 that is the problem, because the earth will adapt. What is very worrying is the speed of change. Levels [at this measuring station] are now increasing 2-3 ppm a year. The rate of increase is much faster than only 10-20 years ago. You can almost see the changes taking place. Never before have CO2 levels increased so fast.” The level of CO2 increased annually by about 1.5 ppm from 1970 to 2000 but has accelerated to about 2.1 ppm during this decade. The measurements obtained in the Arctic are typically a little higher than those obtained in Hawaii by the National Oceanic and Atmospheric Administration (NOAA). A climate scientist from the Met Office Hadley Center in Britain, Dr. Vicky Pope, said that “These are quite large numbers. It sounds like this is an Arctic phenomenon. It fits with the general increase in emissions. You would expect the concentrations of CO2 to grow.” Despite all this alarming information we still hear reports that leaders in China and India and even in the United States contend that coal needs to play a large role in meeting future energy needs. This vision of the future which includes more coal burning is not very promising.

Move Over CO2, Here Comes NF3 and SO2F2

While most of the attention has been focused on the increasing concentration of carbon dioxide in the atmosphere when it comes to global warming, two little known greenhouse gases, nitrogen trifluoride (NF3) and sulfuryl fluoride (SO2), are rapidly increasing in concentration, although their levels are still low. The latest measurements published were made by a team of scientists from the US and Australia. In a story posted on RedOrbit News, one of the scientists, Dr. Paul Fraser from the Center for Australian Weather and Climate research, is quoted as saying that “these gases have significant global warming potential.” Somewhat ironically nitrogen trifluoride is used in the manufacture of thin-film solar panels. It is also used in the manufacture of various type of electronic devices including liquid-crystal flat panel screens. Sulfuryl fluoride is used in fumigation. Dr. Fraser believes that in addition to likely setting targets for the better known greenhouse gases, it is likely targets will be set for these two other greenhouse gases in any revision of the Kyoto Protocol.

Forget about Limiting Global Warming to 2°C Says Climate Expert

Some very sobering opinions on global warming are emanating from climate scientists gathered in Copenhagen for an international climate meeting. A particularly gloomy picture of the situation comes from Professor Katharine Richardson, chair of the scientific conference’s steering committee. As reported by the Times Online, Professor Richardson said in an interview that “We can forget about the 2°C. We are now facing the situation where we have to avoid a 5°-6°C rise in temperature.” The 2°C mark of course is the amount that many climate scientists have been saying is the most that global temperature can rise from preindustrial times without kicking off catastrophic climate change. Professor Richardson says “What we know now is that we are we facing the worst case scenario.” She came to this extremely gloomy conclusion after looking through hundreds of scientific papers that had been submitted to the conference. It seems hard to imagine that any politicians will embrace this forecast for certain disaster. How can a leader not express any hope except the hope that an even worse catastrophe than one certain to come can possibly be avoided? Certainly they would have to at least express the hope that some sort of geoengineering scheme would come to the rescue. Or, at least in democracies, the people could elect deniers and take comfort in global warming denial as so many Americans do today.

US Climate Expert Says Global Warming Could Get “Out of Control” by End of this Century

The predictions on climate change by the UN's Intergovernmental Panel on Climate Change (IPCC) over the years keep getting gloomier and gloomier, but a leading climate scientist from Stanford University, Chris Field, thinks the IPCC's latest predictions are not gloomy enough. A report by Agence France-Presse posted on Yahoo News says that Field, a senior member of the IPCC, believes that a greater-than-predicted increase in greenhouse gas emissions from 2000 to 2007, mainly attributable to coal burning to generate more electricity in developing countries, has increased the potential for disastrous effects of global warming. He warns specifically about higher temperatures increasing the possibility of tropical forests burning as a result of drying out and Arctic tundra thawing, each of which could potentially release huge amounts of greenhouse gases. This would set up a positive feedback mechanism which Field says “could spiral out of control by the end of the century.” Field says that “We don’t want to cross a critical threshold where this massive release of carbon starts to run on autopilot.”

Emergency Meeting of Climate Scientists Scheduled to Break Political Logjam

In what almost sounds like something out of a Hollywood disaster movie, the Guardian reports that climate scientists from around the world will hold an emergency meeting in Denmark next month to try to get the politicians moving on fighting global warming. An update will be published on the Intergovernmental Panel on Climate Change’s report of two years ago which will be more specific on some issues such as prediction of sea level rise. It would seem that there is already far and away enough information about the climate change crisis to warrant all-out action to stop global warming, so it is a little hard to fathom what this meeting will accomplish. The public doesn’t seem concerned enough to take to the streets and demand action so most politicians seem content to fiddle away as the disaster unfolds. Gradual warming with lag times of decades isn’t the type of crisis that will arouse the masses. The past two decades of mostly apathy is evidence of that.

G8 Countries Fight Climate Change with Vagueness

As the effects of global warming become more and more evident with fires from extreme dryness raging on the US West Coast, 500-year storms hitting the Midwest two straight decades, prediction from scientists that the North Pole may be free of ice this summer, and so forth, the Group of 8 wealthy nations meeting in Japan agreed on a global warming statement that was short on adequate commitment and long on ambiguity. They did agree to reduce carbon emissions 50% by 2050, however, this was far short of the 80% to 90% reductions called for by leading climate scientists and the usual baseline year of 1990 was not mentioned. They also did not set any short term goals, such as a specific target to reach by 2020. As reported in The New York Times, emerging economic powers such as China and India supported the 50% reduction target, which is the first time these countries have committed to any reduction target, but they refused to take action until wealthy countries took aggressive action. Given the urgency of the global warming problem and what would be required to take effective steps, the G8 did little more than put their toe in the water.

One way to comprehend the feebleness of the G8 global warming statement is to compare it with The 2030 Challenge from the nonprofit organization Architecture 2030. This challenge calls for the global architecture and building community to immediately reduce the fossil fuel greenhouse emissions of all new buildings, developments, and major renovations by 50% and then by increments of 10% every five years beginning with 2010 so that by all 2030 all new buildings and major renovations are carbon neutral. This would permit an immediate moratorium on new coal-fired power plants and a phase out of such plants by 2030. It wouldn’t completely solve the problem but it would be a very significant step. The action could begin at once and no new technology is needed. Of course the coal industry would take a big hit and that is not something the G8 leaders are eager to confront. Maybe we need new G8 leaders. Perhaps the only hope is that we will be getting a new leader of the United States very soon.

Texas Listed as One of the World’s Top Ten Greenhouse Gas Polluters

The state of Texas is known for doing things in a big way and polluting the atmosphere with greenhouse gases is no exception. The Telegraph reports that the US Energy Information Administration says that in 2003 Texas emitted 670 million metric tons of carbon dioxide which would make it the seventh largest polluter in the world. The Telegraph article notes that in contrast to states that are attempting to reduce travel by automobile, in Texas, the governor, Rick Perry, is pushing to get a swath of highway built across his state that in some places would be as wide as one quarter of a mile. The article also notes that in a poll last spring fewer than 4% of Texans said that the environment as one of the country’s most pressing issues.

Although at the Republican-dominated state level anti-environmentalism appears to hold sway, at the local level things look more green. At least 19 mayors of Texas cities, including the mayors of Austin, Dallas, Fort Worth, and San Antonio, have signed the US Mayors’ Climate Protection Agreement. This document includes a nonbinding pledge to reduce greenhouse gas emissions in communities to 7% below 1990 levels by 2012. Whether political pressure from below will be enough to get state leaders to come to their senses remains to be seen. Clearly the US can’t reduce its greenhouse gas emissions enough to fight global warming if Texas doesn’t join in.

Bali Summit Leaves Lots of Unanswered Questions in Its Wake

It appears that US did not succeed in completely wrecking the UN Summit in Bali on global warming that just ended. According to a report in The Guardian, after opposition to the refusal of the US to cooperate grew so intense it finally conceded a point and agreed to stop opposing technological and financial assistance to the poorer counties. But the US did succeed in removing from the final document all references to specific reductions in greenhouse gas emissions, which probably was its main objective. So while the process moves forward, perhaps concluding with a final agreement by the end of 2009, it remains unclear where the process is headed. The science says that at a minimum greenhouse gas emissions must be stabilized by 2015 and reductions of about 80% from 1990 levels must occur by 2050. There is nothing in the final Bali document to acknowledge these goals which are aimed at preventing catastrophic climate change.

Politically, it appears that to have any hope of avoiding this impending catastrophe three things have to happen in the US elections next November: the Democrats retain control of the House, the Democrats win the Senate by several seats, and a Democrat or John McCain is elected president. Unless those three things fall into place there doesn’t seem to be any reason to continue to hold out hope. Even if those three things happen there still is no reason for any optimism. At the moment, the problem of limiting climate change seems overwhelming.

Malaysia Leads the World in Greenhouse Gas Emission Growth Rate

It is hard to believe that any country can outdo China in increasing the rate of greenhouse gas emissions with the Chinese building new coal-fired power plants at the rate of about one a week but it looks like Malaysia has done just that. According to the recently released United Nations Development Report, during the period of 1990 to 2004 emissions of carbon dioxide increased in Malaysia by 221%. This growth rate is tops among the 30 biggest greenhouse gas emitters. According to the Associated Press, this rapid growth in emissions has occurred even though Malaysia ratified the Kyoto Protocol and “has taken several initiatives to use renewable energy as well as ways to cut emissions.” Overall, this country of 27 million people ranks as the 26th largest greenhouse gas emitter in the world. Based on its growth rate of emissions it appears likely to move up the list quickly. In the fight against global warming Malaysia seems to be a country that needs to be closely watched.

Nothing Funny About Belching Livestock

It is not surprising that many people find it hard to take seriously the claims that methane expelled by cows can be a threat to the planet. It seems more like gross-out humor than serious climate science. Particularly since many people believe that the methane comes out at the end of the digestive tract as in humans. Actually most of this methane is expelled by belching.

According to a recent article in The Christian Science Monitor cows burp about once every 40 seconds. Their digestive processes yield as much as 100 gallons a day of methane and much of it is released through belching. Multiply that by all the cows in the world and you can be begin to see why this has no relationship to toilet humor. Considering that methane is a much more powerful greenhouse gas than carbon dioxide with regard to heat trapping (although it does not last nearly as long in the atmosphere) it is clear that this is very serious business.

To make this subject even more grim cows are not the only type of livestock that burp methane. For example, sheep are also part of this problem. A reporter from a Western Australian radio station discovered that in her part of the world this is particularly true because of the high salinity which results in the sheep eating bush that generates lots of burping.

Kay Balatero recently discussed the issue of belching cows on Gristmill blog and noted that scientists are looking for ways to change the diet of livestock to cut down on the belching. She finds herself doubting the wisdom of this effort:

But I'm somewhat skeptical about this dietary tampering; the idea of manipulating cow diets even further than we already have is a little disconcerting. We've seen corn-fed CAFO [confined animal feeding operations] cows become more susceptible to disease as a direct result of eliminating their natural diet of grass, leading to overuse of antibiotics by the beef industry. Would it be better to leave well enough alone, and simply consume less (sustainably raised) beef?

In theory, the problem could be solved by humans becoming vegans in vast numbers. Who needs billions of livestock if we no longer eat beef or lamb or consume dairy products such as milk, cheese, ice cream, and yogurt. The chance of this happening seems to be zero. If civilization is going down, it hardly seems likely that people would give up such perceived pleasures as eating a choice cut of grilled steak or a juicy hamburger from the barbecue during the descent.

Will Greener Planes Bring Meaner Conditions Around Airports?

Generally reducing greenhouse gas emissions is associated with providing other environmental benefits but in a Washington Post article the director of research and technology at Rolls-Royce, Richard J. Parker, says that focusing on reducing carbon dioxide emissions by engineers might result in new engines that are noisier or produce more of the environmentally troublesome nitrogen oxides than present engines. In the words of Parker:

"Will people living near airports win out, or will the planet as a whole win out?"

Not a great choice. Of course, there is always the option of flying less but this also has negative consequences, particularly for people in less developed areas who depend on hoards of tourists booking their hotels to survive economically. It seems that choices have to be made and everyone can’t win.
