‘At least since a 2006 United Nations report asserted that livestock is responsible for a full 18 percent of greenhouse gas emissions — a higher percentage than that caused by transportation — a debate over meat consumption and climate change has been cooking.
The latest round involves a recent editorial in the Archives of Internal Medicine by Barry M. Popkin, a professor of nutrition at the University of North Carolina. In it, Mr. Popkin revisits several studies linking meat not just with heart disease and other health issues, but also with worldwide consumption of energy and water resources — and global warming.
Water use, Mr. Popkin writes, is two to five times greater worldwide for animal-source food than for basic crops such as legumes and grains. He further argues that livestock production accounts for 55 percent of the erosion process in the United States and is also responsible for one-third of the total discharge of nitrogen and phosphorous to surface water.’

‘Information gleaned from a Greenland ice core by an international science team shows that two huge Northern Hemisphere temperature spikes prior to the close of the last ice age some 11,500 years ago were tied to fundamental shifts in atmospheric circulation.’

‘Australia has issued a health warning about air pollution for travelers to Hong Kong. Australians with pre-existing breathing conditions or heart problems should be careful visiting the city. Much of the bad air in Hong Kong blows in from Guangdong, China’s most important manufacturing province. But there is plenty of evidence many factories are closing and many workers have left because the international economic crisis has cut demand for Guangdong’s industrial goods. That should mean less air pollution.
…Trade associations had been pressuring the local government to ease up on enforcing environmental regulations on struggling factories. But Wu Hong Jie, who heads the Pollution Control Division in Guangdong’s Environmental Protection Department, says no one’s backing down on enforcement. He says, “Whatever happens, we should stick to the environmental standards. We can find other ways to help companies survive. We shouldn’t just let them pollute.” But economic growth has long come first in this region.’

‘Three decades later, fears of an atomic catastrophe have been largely supplanted by fears about global warming, easing nuclear energy into the same sentence as wind and solar power. Dogged by price spikes and an environmental assault on carbon dioxide emissions, fossil fuels are the new clean-energy pariah.’

‘[BEIJING] A project to improve water quality in China has been launched by the government, which says it is the largest expenditure on environmental protection since the founding of the People’s Republic in 1949.
The project, which has an estimated budget of more than 30 billion Chinese yuan (around 4.4 billion US dollars) over 12 years, aims to counter the deteriorating water quality affecting millions of Chinese people and their livelihoods.’

‘March 23 (Bloomberg) — Nations are starting to agree on how rich countries could help pay for greenhouse-gas reduction and climate-change adaptation in developing markets, the United Nations said.
A proposed registry would list “nationally appropriate mitigation actions” by developing countries such as China and India and match them with pledges of financial and technological support by developed nations, the UN said in a document on the Web site of the UN Framework Convention on Climate Change.
Countries are “converging” on how the registry would work as part of UN climate talks this year, according to the March 17 document. The negotiations will culminate in a December meeting in Copenhagen. Emerging markets want richer countries to cut emissions first, saying the U.S., the European Union and other industrialized nations have contributed most to climate change. Only developed countries have targets under the 1997 Kyoto Protocol, which runs through 2012.’

‘WASHINGTON — China’s top climate negotiator’s visit to Washington Monday sent a fresh signal that the two countries, which account for about half the world’s greenhouse gas emissions, have a long way to go to reach a common agreement on how to cut emissions to prevent serious climate change.
China shouldn’t have to take responsibility for the 15 percent to 25 percent of its emissions that result from making products for the rest of the world, said Li, the director of the Department of Climate Change in China’s National Development and Reform Commission. ‘
