【bio-news】全球变暖，健康也要付出代价

BEIJING (Reuters) - Deadly heatwaves and hurricanes and expanding malaria and Dengue fever infections appear to be some of the health consequences of global warming, an expert on health and environmental change said on Friday.
"The thing that excites our governments most, and the public, is the prospect of climate change doing damage to the economic system," Tony McMichael, a professor at Australia's National University, said in Beijing.
"But much worse, of course, in terms of real sustainability is damage to the life-support system," McMichael, who is studying the links between temperature rises and disease, added.
Last week, the British government issued a report warning that global warming, driven by man-made emissions of greenhouse gases that keep heat in the atmosphere, could devastate global growth, plunging the world into an economic crisis on a par with the 1930s Depression.
McMichael told Reuters that the world now recognises that global warming has probably exacerbated climate changes.
Now scientists are trying to understand how environmental change may do also more elusive harm to health by spreading less well-known diseases, drying up water, and displacing people in waves of environmental refugees, McMichael added.
"You could reasonably infer that a certain percentage of those deaths were do to the climate change component," he said.
McMichael was in Beijing to attend the launch of a new international effort to study global environmental change and health. A report for the programme offered some clues of the scale of potential havoc.
It said that 3 billion people may be threatened by Dengue fever because of climate change and urbanisation, 40 percent of the world's population may be threatened by malaria, and malnutrition due to climate change and loss of land and water could put 840 million at risk.
"Global climate change will have diverse, escalating impacts on human health," said the report.
Even if countries agreed to immediately cut emissions of greenhouse gases, changes in climate -- and disease -- will be unavoidable due to current greenhouse gas levels, it said.
McMichael is helping prepare the next report of the Intergovernmental Panel on Climate Change, the United Nations group that assesses research on global warming and its effects. The report is due out early next year.
But the new scientific effort announced in Beijing will look beyond global warming to examine how other environmental hazards may damage health.
Loss of forests and natural diversity, urbanisation, and the the spread of warm-climate species and diseases into once-cool climates may all take a heavy toll on human health, scientists at the launch said.
Yet the connections between these changes are too complex and intertwined to be treated in isolation from each other, said McMichael.

气候变化同样损害健康

BEIJING (Reuters) - Deadly heatwaves and hurricanes and expanding malaria and Dengue fever infections appear to be some of the health consequences of global warming, an expert on health and environmental change said on Friday.
北京（Reuters）—— 周五，一位健康与环境变化的专家说，致命的热浪和飓风，及蔓延的疟疾、登革热感染，可能是全球变暖对健康带来的后果。
"The thing that excites our governments most, and the public, is the prospect of climate change doing damage to the economic system," Tony McMichael, a professor at Australia's National University, said in Beijing.
澳大利亚国立大学的教授Tony McMichael在北京谈到：“我们的政府和公众最关心的是预见气候变化对经济的影响”，
"But much worse, of course, in terms of real sustainability is damage to the life-support system," McMichael, who is studying the links between temperature rises and disease, added.
“但其实更糟的应该是对生命支持系统的影响”，他正在研究气候变暖和疾病之间的联系。
Last week, the British government issued a report warning that global warming, driven by man-made emissions of greenhouse gases that keep heat in the atmosphere, could devastate global growth, plunging the world into an economic crisis on a par with the 1930s Depression.
上周，英国政府发表公报，警告说由人为释放的温室气体导致的全球变暖，会严重阻碍全球经济发展，使全世界陷入与20世纪30年代的大衰退同等的经济危机中。
