Feds OK natural gas pipeline expansion in Pacific Northwest over environmentalist protests_我的网站

The Federal Energy Regulatory Commission gave it the green light in a vote on Thursday.TC Energy plans to modify three compressor stations along the pipeline — in Kootenai County, Idaho; Walla Walla County, Washington; and Sherman County, Oregon. Compressor stations help maintain the pressure and flow of gas over long distances in a pipeline. Environmental groups criticized the decision of the commission, which "failed to listen to Senators, Governors, State Attorneys General, Tribes, and the public in its rubber stamp of unnecessary fracked gas in the Northwest,” said Audrey Leonard, staff attorney for Columbia Riverkeeper, an environmental nonprofit, in a statement.Leonard said potential spills and explosions on the pipeline, which was built in the 1960s, would not only harm the environment but also present a heightened wildfire risk in the arid regions it passes through.“An explosion of that level in eastern Washington or eastern Oregon would be catastrophic,” she said.Leonard said Columbia Riverkeeper will appeal the federal regulators’ decision and submit a petition for a rehearing. The pipeline belongs to TC Energy of Calgary, Canada — the same company behind the now-abandoned Keystone XL crude oil pipeline. The company said the project is necessary to meet consumer demand.Environmentalists and officials opposed to the project have expressed concern about TC Energy’s safety record. Its Columbia Gas Transmission pipeline exploded in Strasburg, Virginia, in July and its existing Keystone pipeline spilled nearly 600,000 gallons of bitumen oil in Kansas last December.The 1,377-mile (2,216-kilometer) pipeline runs from the Canadian border through a corner of Idaho and into Washington state and Oregon, connecting with a pipeline going into California.While Idaho’s Republican governor and congress members said that imposing other states’ climate policies would be “misguided,” Democratic officials in the other states called on federal officials to reject the plan. After the vote, Washington Gov. Jay Inslee, a Democrat, condemned the decision.The project is “incompatible with our climate laws,” said a letter to the agency by Democratic U.S. Senators Ron Wyden and Jeff Merkley of Oregon and Patty Murray and Maria Cantwell of Washington.“GTN Xpress represents a significant expansion of methane gas infrastructure at a time when California, Oregon, and Washington are moving away from fossil fuels,” the senators said.The attorneys general of the three states, citing the commission's draft environmental impact statement for the project, said it would result in more than 3.47 million metric tons of greenhouse gas emissions per year for at least the next three decades. The agency’s final environmental assessment revised that number downward by roughly half in calculations contested by environmental groups.The agency’s chairman, Willie Phillips, reiterated its stance after Thursday’s vote.“There was no evidence presented that this project would significantly increase greenhouse gas emissions,” he told reporters. “The commission determined that this project was needed and therefore we support its approval.”In its final environmental impact statement for the project issued last November, the federal agency said the compressor stations were in non-forested areas with low to moderate fire hazard. It concluded the project “would result in limited adverse impacts on the environment.”“Most adverse environmental impacts would be temporary or short-term,” the federal agency said. The agency recommended certain steps, such as requiring the company to train its personnel and contractors on environmental mitigation measures before any construction begins. But environmental groups say the assessment didn’t adequately address the harm caused by the project, including by fracking to obtain the natural gas that flows through the pipeline. Fracking is a technique used by the energy industry to extract oil and gas from rock by injecting high-pressure mixtures of water, sand or gravel and chemicals. It has been criticized by climate and environment groups for increasing emissions of methane, an extraordinarily potent greenhouse gas. ___Claire Rush is a corps member for the Associated Press/Report for America Statehouse News Initiative.

B | 社交媒体上，“经典焕新”话题持续升温，观众纷纷截取对比画面，分享“重逢”旧作的新鲜体验。图为《红楼梦》修复前后对比。然而，惊喜之余，修复中的“AI痕迹”也引发广泛讨论。《大明王朝1566》中，有观众指出个别角色面部出现“异化”甚至“外国人”既视感；《少年包青天》里，李冰冰饰演的凌楚楚近景尚可，中景时脸部却“判若两人”；《寻秦记》中一名丫鬟的呈现方式更显突兀，人物由模糊渐趋清晰，AI却直接“置换”了一张数字合成面孔。此外，部分镜头景深破坏、锐化过度、字幕错别字等问题，也让整体观感打了折扣。技术带来的违和感，成为观众吐槽最为集中的焦点。图为《少年包青天》AI修复后李冰冰饰演的凌楚楚。客观而言，AI带来的违和感与其效率优势相伴而生。以经典电影《少林寺》为例，传统人工修复需耗时约8个月，而优酷自研AI系统可在2天内完成全片修复，效率提升逾百倍。速度的飞跃固然令人振奋，但也暴露出高速运转下的技术短板。优酷技术团队坦言，当前AI修复经典老片还存在一定的局限性，依然无法避免在个别画面中出现人物失真、服饰花纹错误、字幕匹配错误等问题。AI可以快速补全像素，却难以精准还原创作者的原始美学意图；远景人脸重构、繁复衣饰纹理的复原，对AI而言仍是挑战。AI修复技术自身的演进，仍需时间沉淀。观众对细节的挑剔恰恰体现了对经典的热爱与珍视，他们既为画质的跃升而欣喜，也为细节的失准而直言，这种热忱本身就是对经典最深的情感投射。正如一位网友所言：“看着那些熟悉的画面变得清晰，就像重逢了老朋友，虽然有些地方还不太完美，但能感受到这份用心。
