China May Be Incapable of Lowering Carbon Dioxide Emissions

China’s Carbon Dioxide Emissions Are Greatly Exceeding Predictions
Much, much harder to achieve may even be an understatement. Perhaps impossible to achieve is more accurate. With all the positive reports about increasing numbers of wind turbines and solar installations being in the news it seems that there is some reason for optimism that atmospheric CO2 levels can kept to a level that does not precipitate catastrophic climate change, but this report on China is quite a reality check.

Bill McKibben Calls for 350ppm Carbon Dioxide Target
Environmental author and activist Bill McKibben, who launched the Step It Up campaign last year, has revealed the next phase of his plan to fight global warming with local activism. The Brattleboro Reformer reports that McKibben told a group of local activists that this next phase will call for a target of 350 parts per million of atmospheric carbon dioxide. As things stand now we are at about 385ppm and heading upward at about 2ppm per year. He is calling his plan 350. McKibben said that “What we need is people in their own communities to take that number and spread it, with music, with art, and take pictures and get it back into that centralized area.” Unlike his Step It Up campaign which was limited to the United States, this new 350 campaign he envisions as international. McKibben clearly understands the precarious situation that excessive emissions of greenhouse gases from human sources has caused saying that “We are in a big, freaking hole and there’s absolutely no guarantee that we are going to get out of it.” So, it is on to 350.

James Hansen Says CO2 Must Be Reduced to 350ppm
The aim of most people fighting global warming is to keep atmospheric carbon dioxide levels from increasing above 450ppm, which is approximately 65ppm above today’s levels. This target has been advocated by climate scientist James Hansen, the head of NASA’s Goddard Institute for Space Studies, and has been also been advocated by the UN’s Intergovernmental Panel on Climate Change. But Hansen is now saying that the target is too high. In an article in the British newspaper The Sunday Times he says:
“If humanity wants to preserve a climate resembling that in which civilisation developed, then the palaeoclimate evidence and ongoing climate change suggest CO2 must be reduced from its current level to between 300-350ppm. A 350ppm target is only achievable by phasing out coal use….We need a moratorium on the construction of coal-fired power plants and we must phase out the existing ones within two decades.”
If Hansen is right, it appears we will just have to accept a planet that does not resemble the one we are familiar with. Limiting CO2 to 450ppm appears to be an almost impossible task, particularly with China and India counting on coal to lift hundreds of millions of people out of a meager existence. Reducing CO2 to 350ppm or even lower doesn’t seem to be a feasible goal. It is hard to imagine the world only 20 years from now without any operating coal-fired plants. According to the article, Hansen will support his view of setting a lower target in a research paper. Until that paper is published and other scientists have a chance to review it is unlikely that the target of 450ppm will revised. However, perhaps we should be prepared for an even gloomier view of the possibility of extracting ourselves out of our global warming predicament than we now have.

IPPC Leader Says Developing Countries Need Increase in Carbon Emissions
Rajendra Pachauri, the head of the UN’s Intergovernmental Panel on Climate Change (ICPCC) recently said when the IPCC released its fourth report of the year that "If there's no action before 2012, that's too late. What we do in the next two to three years will determine our future. This is the defining moment." It is hard to but it better than that. However, it appears the “we” which Pachauri refers to includes only the developed countries because in a statement made at the world conference on climate change being held in Bali, Indonesia he said that to get millions people out of poverty developing nations need to boost carbon emissions. In an AFP article Pachauri is quoted as saying that “If you have the case of India, a half billion people who do not even have electricity, what mitigation (of carbon emissions) can you carry out?”
Pachauri’s view is opposite to the conclusion from a report by the Center for Global Development (CGD) which I described yesterday. That report said that an increase in carbon emissions by developing counties to get large populations out of poverty would result in catastrophic climate change regardless of what developed countries did. Perhaps the president of the CGD, Nancy Birdsall, has the answer to this dilemma when she says as reported in DailyIndia that “To avoid a shared global disaster, we in the rich countries need to cut our own emissions quickly and do much more to help developing countries shift to a low-carbon future while at the same time meeting the just aspirations of their people for a better life.” The latter task is likely to be a tough sell in the developed countries but it may be our best hope.

Report Says Developing Countries Need to Curtail Carbon Emissions

Ships Are Outpolluting Planes
The was a large global warming protest recently at London’s Heathrow Airport but so far there has been no such protests at any shipping port. Maybe there should be. A shipping industry group called Intertanko has released a report which says that carbon dioxide emissions from shipping are now almost double that from aviation. In an article on the report from ABC News in Australia it says that Intertanko attributes the growth in carbon dioxide emissions from shipping to an increase in global trade and the use of more fuel to speed up the delivery of goods.
Concerns about shipping in this country have largely focused on terrorism. In the US critics of the government’s security measures have complained that a large percentage of shipping containers that arrive in this country are never checked. There has been little concern over the amount of carbon dioxide released getting the containers over here. This report should finally place shipping under the global warming microscope.

Southern Utilities Cling to Coal Burning
"If we are irrational about it and we cripple our economy or cripple our industry and we realize carbon dioxide wasn't the source of the problem, then we'll be real regretful."
