Title:NASA head: ‘No reason to doubt’ climate change science

Bridenstine, speaking at a Senate Appropriations Committee subpanel's hearing, said his views on climate change have changed from his previous position that it is unclear how much humans contribute.

布里登斯汀在参议院拨款委员会听证会上发言说，他对气候变化的看法改变了他先前的立场，即尚不清楚人类对气候变化的贡献有多大。

"The National Climate Assessment that includes NASA, and it includes the Department of Energy and it includes NOAA, has clearly stated it is extremely likely — is the language they use — that human activity is the dominant cause of global warming,"  he said, referring to ongoing government-wide research on climate, including a major report last year.

"国家气候评估包括美国航天局，它包括能源部，包括美国国家海洋和大气管理局，明确说明这种评估极有可能？”他说，指的是正在进行的全政府气候研究，包括去年的一份重要报告。

"I have no reason to doubt the science that comes from that."

“我没有理由怀疑来自那的科学。

"Yes,"  he responded.

“是的，”他回答。

NASA is one of the primary agencies focused on climate change in the federal government. Its satellites and other equipment closely track temperatures of the Earth's surface and atmosphere, as well as atmospheric concentrations of greenhouse gases and other important measures.

美国航天局是联邦政府专注于气候变化问题的主要机构之一。它的卫星和其他设备密切跟踪地球表面和大气的温度以及温室气体的大气浓度和其他重要措施。

Bridenstine's climate skepticism was one of the chief reasons Democrats opposed his nomination to lead NASA and sought to block his confirmation to the post.

布里登庭的气候怀疑是民主党反对美国宇航局领导提名并试图阻止他获得这一职位的主要理由之一。

He was nonetheless confirmed by a Senate vote of 50 to 49 last month, entirely along party lines.

不过，参议院上个月以50票对49票投票确认了他的身份，这完全符合党的路线。
