He published an article in science: clean energy, "irreversible"-Obama-IT information
Outgoing United States President Barack Obama 9th wrote, development trends in clean energy economy "irreversible" and warned Trump not withdrawal from the United Nations to address climate change, President-designate of the Paris agreement.
Obama day in United States Science magazine published entitled irreversible of clean energy momentum of long paper, pointed out that "large science records" showed that climate changes is "real of, and not ignored", if allowed regardless of, greenhouse gas emissions continues to increased will led to global temperatures in century late rose 4 degrees Celsius above, global economic annual will loss about 4%, which country and United States country annual loss 340 billion to 690 billion dollars.
Obama said, even though our understanding of climate change impacts "troubling emerging", but the United States should take and what kind of policy debate, which is evident in the current period of presidential transition. But he believes that "putting aside current political", "during his presidency of the emerging clean energy economy trend will continue."
Obama lists the 4 reasons, starting from 2008 to 2015, United States economic growth of over 10%, while carbon dioxide emissions from the energy sector decreased by 9.5%, the result "should be denied the idea, that the fight against climate change needs to accept economic slowdown and lower living standards. ”
3 reasons: United States enterprises increased investment in clean energy; United States marked reduction in cost of wind and solar power, are going through the transition from coal to natural gas production; racing momentum of the global clean energy economy.
Obama said that Trump is not obligated to follow his climate policies, but if the United States withdraws from the Paris agreement, the United States will "throw on the table (requires other countries to take measures) seat. "He said, in response to climate change, Trump should follow the advice and guidance of scientists and economists.
Climate change is one of the Obama wants to leave a legacy. But trump the President-designate has said climate change is a hoax, and threatened to quit during the election of the Paris agreements. After the election, Trump had changed the call on whether to withdraw from the Paris agreement, "openness", but he chose the environmental protection agency and department heads are climate change skeptics, for Secretary of State in charge of foreign oil companies, which many feared United States of climate policy will be a major setback.
奥巴马在《科学》发表文章：清洁能源发展“不可逆转” - 奥巴马 - IT资讯
即将离任的美国总统奥巴马9日撰文说，发展清洁能源经济的趋势“不可逆转”，并警告候任总统特朗普勿退出联合国应对气候变化的《巴黎协定》。
奥巴马当天在美国《科学》杂志发表题为《不可逆转的清洁能源势头》的长文，指出“大量科学记录”表明气候变化是“真实的、不可忽视”，如果放任不管，温室气体排放继续增加将导致全球气温在本世纪末上升4摄氏度以上，全球经济每年将损失约4%，其中国和美国国每年损失3400亿至6900亿美元。
奥巴马说，尽管我们对气候变化影响的认识“令人不安地日益清晰”，但对美国应该采取什么样的政策还存在争论，这在当前总统过渡期表现得很明显。但他相信，“把近期内的政治放在一旁”，“在他总统任期内出现的发展清洁能源经济的趋势将会继续下去”。
奥巴马列出了4个原因，首先是2008年至2015年间，美国经济增幅超过10%，而来自能源领域的二氧化碳排放则下降9.5%，这一结果“应该否定了这样的观点，即与气候变化做斗争需要接受经济增速减缓与生活标准降低。”
另3个原因是：美国企业在清洁能源方面的投资增加；美国风力和太阳能电力成本显著下降，正经历从以煤为主到以天然气为主的生产转型；全球出现了发展清洁能源经济的竞赛势头。
奥巴马说，特朗普并不一定要遵循他的气候政策，但如果美国退出《巴黎协定》，那么美国将会“丢掉在谈判桌上（要求他国采取措施）的座位。”他认为，在应对气候变化方面，特朗普应听从科学家与经济学家的建议与指导。
应对气候变化是奥巴马希望留下的政治遗产之一。但候任总统特朗普曾称气候变化是骗局，并在选举期间威胁要退出《巴黎协定》。当选后，特朗普曾改口称对是否退出《巴黎协定》持“开放态度”，但他挑选的环境保护局和能源部负责人都是气候变化怀疑论者，主管外交的国务卿人选也来自石油公司，这让许多人担忧美国的气候政策将会发生大倒退。
