    Climate Panel Recommends Global Temperature Ceiling, Carbon Tax

A panel of scientists has presented the United Nations a detailed plan for combating climate change. VOA's correspondent at the UN Peter Heinlein reports the strategy involves reaching a global agreement on a temperature ceiling.

    United Nations - A group of 18 scientists from 11 countries is calling on the international community to act quickly to prevent catastrophic climate change.

    In a report requested by the United Nations and partially paid for by the privately funded U.N. Foundation, the panel warns that any delay could lead to a dangerous rise in sea levels, increasingly turbulent weather, droughts and disease.

    The report was issued three weeks after the Intergovernmental Panel on Climate Change concluded that global warming is real and caused in large part by human activity. But unlike the IPCC report, this latest document makes policy recommendations.

    Panel member John Holdren of Harvard University says the world must be mobilized immediately to avoid catastrophe. "Climate change is real, it's already happening, it's already causing harm, it's accelerating and we need to do something about it, and we need to do something about it seriously, starting now. Our specific conclusions are that if the world were to go past the point of an increase above pre-industrial temperatures greater than 2 to 2.5 degrees Celsius, we would be in a regime where the danger of intolerable and unmanageable impacts on well-being would rise very rapidly," he said.

    The panel's recommendations include a series of steps to cut the rate at which temperatures are rising. Chief among them are a global agreement on an acceptable ceiling for temperature rise and finding ways of adapting to cope with the damage already done.

    Holdren, however, says even these measure will achieve very little unless they are accompanied by a global tax on greenhouse gas emissions. "We don't think ultimately society will get it right in terms of the full range and scope of activities needed to reduce greenhouse gas emissions, until there is an additional incentive in the form of a price on greenhouse gas emissions, either through a carbon tax or a cap and trade approach," he said.

    The United States is the biggest emitter of greenhouse gasses, but is not a party to the cap and trade system contained in the Kyoto Protocol on climate change.

    Nevertheless, the Bush administration has set a target of cutting U.S. greenhouse gas emissions by 18 percent by 2012, and is spending $3 billion a year on climate change research.

    Peter Raven, the head of the Sigma Xi Scientific society and co-author of the latest report, says success in limiting the effects of global warming will require private sector leadership, and a combined effort by the U.S. and the international community. "The private sector is doing a very good job, and kind of leadership we're calling for from the United Nations and international organizations and the kind of leadership the United States is moving towards will both be key ingredients in that," he said.

    A U.N. spokesman says Secretary-General Ban Ki-moon is considering calling a summit meeting on climate change later this year. Environmental activists are calling on Mr. Ban to play a leading role in the process of negotiating a successor to the Kyoto agreement, which expires in 2012.

    Conservation May Limit Global Warming

Researchers support carbon taxes, a ban on coal-fired power plants and an end to beachfront construction.

    United Nations - Dramatic worldwide climate changes can no longer be avoided, but there is still time to stave off the worst consequences of global warming, an international research team said Tuesday.

    The scientists from 11 countries urged sweeping conservation measures to hold the expected increase in temperatures to no more than an average of 3.6 degrees Fahrenheit - less than half the expected increase if emissions of greenhouse gas and soot continue unabated.

    Based on two years of study, the scientists called for bold actions, including carbon taxes, a ban on conventional coal-fired power plants and an end to beachfront construction worldwide.

    The researchers were financed by the nonprofit United Nations Foundation and the 60,000-member research society Sigma Xi.

    "Unlike many reports from scientists, this report gives very clear recommendations for what the international community and nations themselves must do to mitigate and adapt to climate change," said biodiversity expert Peter Raven, director of the Missouri Botanical Garden, who helped prepare a Sigma Xi study.

    With its emphasis on policy recommendations, the panel's effort marks a shift in the international politics of pollution and climate change, analysts said. Researchers are no longer debating whether human-induced global warming is genuine, but have begun the painstaking process of negotiating international agreement on what to do about it.

    Their effort comes on the heels of a landmark United Nations report last month that concluded rising temperatures would continue to increase even if greenhouse gas emissions could be held to current levels.

    Global temperatures have increased about 1.4 degrees Fahrenheit over pre-industrial levels, the researchers said. To meet the scientists' goal, global CO2 emissions must level off by 2015 and drop by two-thirds of that level by 2100.

    They urged stricter fuel efficiency standards, as well as fuel taxes, registration fees and rebates that favor more efficient transportation, which today is responsible for 40% of the world's carbon emissions.

    A 20-fold improvement in car efficiency is well within existing technology, they said. Moving freight by rail instead of truck could also cut emissions substantially.

    The researchers also recommended the expanded use of biofuels to reduce dependence on the oil that accounts for one-quarter of the world's CO2 emissions. They endorsed broader use of nuclear power, if it can be made safer. Energy research budgets worldwide ought to triple, they said.

    In addition, the scientists called for improved designs of energy-efficient appliances, office equipment and "greener" commercial and residential buildings. Taken together, the heating, cooling and lighting of buildings accounts for about 30% of the world's greenhouse gas emissions.

    Most tellingly, the panel called for a ban on any new coal-fired power plants that cannot be equipped to capture and store the carbon dioxide they emit.

    All told, the U.S., China and India plan to build about 850 coal-fired plants over the next decade, which by environmentalists' calculations would pump as much as five times more carbon dioxide into the atmosphere than international control measures aim to eliminate.

    No matter what people do to reduce soot or curtail emissions of carbon dioxide and other greenhouse gases, the world will continue to warm somewhat, and people will have to adapt, the researchers said.

    To minimize the hazards of rising sea levels and more powerful storms, the group called for a worldwide ban on beachfront construction near existing high-tide lines.

    To reduce the effects of climate-related disasters, such as floods or prolonged droughts, the panel urged better international emergency response measures, warning that there may be as many as 50 million environmental refugees by 2010.
