【科技报道】气候灾害将进一步恶化 Climate disasters will worsen

A new U.S.government report says climate change is affecting the United States.It warns that the danger of destructive weather events—from powerful storms to extremely dry weather and wildfires—is worsening.


美国政府的一份新报告说,气候变化正在影响美国。它警告说,破坏性天气事件的危险正在恶化,从强风暴到极端干燥的天气和野火。


Some findings are in conflict with the statements and policies of President Donald Trump.


一些调查结果与唐纳德·特朗普总统的声明和政策相冲突。


The report,called the Fourth National Climate Assessment,was released on November 23.It was written long before the deadly fires in California this month and before Hurricanes Florence and Michael struck the East Coast.


这份名为“第四次全国气候评估”的报告于11月23日发布。早在本月加州发生致命火灾之前,也早在飓风佛罗伦萨和迈克尔袭击东海岸之前,这本书就已经出版了。

The report noted that new U.S.records for destructive weather have been set in recent years.Weather-related damage has cost nearly$400 billion since 2015,The Associated Press reported.


报告指出,美国近年来创下破坏性天气的新纪录。美联社报道,自2015年以来,与天气有关的损失已近4000亿美元。


The climate assessment is required by law every few years.It was based on more than 1,000 earlier research studies.More than 300 researchers in 13 U.S.government offices and agencies prepared the report.It explains how the burning of coal,oil and natural gas is affecting different areas of the country and how this affects the U.S.economy,including energy and agriculture.


法律要求每隔几年进行一次气候评估。这是基于1000多个早期的研究。来自13个美国政府部门和机构的300多名研究人员编写了这份报告。它解释了燃烧煤炭、石油和天然气对美国不同地区的影响,以及这对美国经济(包括能源和农业)的影响。


The report noted that temperatures in the Lower 48 states have risen 1 degree Celsius since the year 1900.By the end of the 21st century,the country will be 1.6 to 6.6 degrees higher,depending on how much pollution is released into the atmosphere.Studies have linked the temperature increase to carbon dioxide and other greenhouse gases.


报告指出,自1900年以来,较低的48个州的气温上升了1摄氏度。到21世纪末,中国的气温将升高1.6到6.6度,这取决于向大气中释放的污染程度。研究已经把气温升高与二氧化碳和其他温室气体联系起来。


The climate assessment warned of longer and more powerful disasters resulting,at least in part,from rising temperatures.It said weather disasters are becoming more commonplace and warned that without aggressive action,they could become much worse.


气候评估警告说,至少在一定程度上,气温上升会导致更长期、更严重的灾害。它说,天气灾害变得越来越普遍,并警告说,如果不采取积极行动,它们可能变得更糟。


The report avoids proposing policy changes.But it said that people must take steps to stop future weather disasters"to avoid substantial damages to the U.S.economy,environment,and human health and well-being over the coming decades."


该报告避免提出政策变化。但报告称,人们必须采取措施阻止未来的天气灾害,“以避免未来几十年对美国经济、环境、人类健康和福祉造成实质性损害”


"Future risks from climate change depend primarily on decisions made today,"the report said.


报告说:“未来气候变化带来的风险主要取决于今天做出的决定。”。


The Trump administration is downplaying the importance of the findings.It says the report was largely based on"the most extreme scenario"and fails to consider new technology and other actions that could reduce carbon emissions and the effects of climate change.


特朗普政府正在淡化调查结果的重要性。报告说,这份报告主要基于“最极端的情况”,没有考虑新技术和其他可能减少碳排放和气候变化影响的行动。


A White House spokeswoman noted that,since 2005,carbon dioxide emissions related to energy production in the United States have dropped 14 percent.Yet emissions worldwide continue to rise.


白宫发言人指出,自2005以来,与美国能源生产相关的二氧化碳排放量下降了14%。然而,全球排放量仍在继续上升。


The Trump administration has eased enforcement of several environmental rules enacted during the presidency of Barack Obama.The administration also has a campaign for the production of fossil fuels like coal.


特朗普政府放松了在巴拉克奥巴马(Barack Obama)任总统期间制定的几项环境法规的执行。政府还发起了一场生产煤炭等化石燃料的运动。


Last year,President Trump announced plans to withdraw the United States from the 2015 Paris Agreement.He said the agreement would hurt the U.S.economy and said there was little evidence it would improve the environment.


去年,特朗普总统宣布了美国退出2015年巴黎协议的计划。他说,这项协议将损害美国经济,并说几乎没有证据表明这将改善环境。


The measure,signed by nearly 200 countries,sets rules for fighting climate change.


这项由近200个国家签署的措施制定了应对气候变化的规则。
