Delegates from nearly 200 countries have spent the past two weeks in Warsaw, Poland. More than 9,000 representatives gathered for a United Nations conference on climate change. Organizers called the meeting to work toward a treaty to fight rising temperatures on our planet. The treaty would be signed in 2015 and take effect after 2020.
Several environmental groups walked out of the climate talks earlier this week. They were protesting what they considered a lack of progress towards a deal to limit carbon dioxide and other global warming emissions. Studies have shown links between such gases and the rise in temperatures.
In the United States, the Environmental Protection Agency is leading government efforts to fight climate change. The agency just ended a series of public hearings across the country. The EPA was seeking comments as it considers tightening clean air rules for coal-burning power plants.
America's 1,000 coal-burning power plants supply 40 percent of the nation's electricity. The plants are responsible for one-third of the global warming emissions. The Obama Climate Action Plan has promised to cut the production of such gases.
Mitch McConnell is the leader of the Republican Party in the United States Senate. He spoke at the EPA hearing in support of his home state of Kentucky, which is a major coal producer.
"By now it is clear that this administration and your agency have declared a war on coal. For Kentucky, this means a war on jobs and on our state's economy."
Brian Patton also spoke at the EPA hearing. Mr. Patton comes from a long line of Kentucky coal mine workers. Today he is president of James River Coal Service. His company has dismissed 725 workers over the past six months. He fears that new rules could bring even greater hardship to an area that is already economically depressed.
"Understand, these are communities of just 1,000, 2,000, 3,000 people. And when you have that type of an economic impact due to regulations that come from Washington, DC -- that have very little understanding of what the outcome is for the local folks, for folks that get up and go to work every day and what that impact will be for their families in the future, and that's wrong."
David Doniger is a climate policy expert with the Natural Resources Defense Council, one of the nation's largest environmental groups. He says it is the duty of the EPA to control carbon as a pollutant. He wants the agency to establish new rules that would move the United States toward a cleaner energy environment.
"No one is proposing standards that would knock out all those power plants. We're talking about a shift from the dirtier ones to the cleaner ones, and from all those fossil fuel-powered ones towards renewable and even nuclear sources of energy."
He says the government is responsible for protecting clean air, not protecting old and dirty power stations.
"That's the only way that we can continue to have the way of life we want without running into the wall on climate change impacts, which in turn will come back and destroy the quality of life we have."
The EPA is now considering comments from the nationwide hearings. The agency plans to announce proposed rule changes in June.

过去两周，来自接近200个国家的代表团齐聚波兰的华沙。超过9,000名代表参加了联合国气候变化会议 。会议组织者召开该会议是为了制定一项公约，应对不断上升的地球气温 。该公约将于2015年签署，2020年后生效 。
本周早些时候，几个环保组织退出气候会谈。他们认为限制二氧化碳和其他温室气体排放的协议进展缓慢，以此提出抗议 。研究发现，温室气体和气温升高有关 。
美国1,000家燃煤发电厂供应全国40%的电量。这些发电厂占全球温室气体排放的三分之一 。奥巴马的气候行动计划曾经承诺减少温室气体排放量 。
麦康奈尔(Mitch McConnell)是美国参议院共和党领袖。他在环保局听证会上发表讲话，支持他家乡所在的肯塔基州，一个重要的产煤基地 。
Brian Patton也在环保局听证会上发表了讲话。Patton家族从事产煤行业历史悠久 。现在，Patton已经是詹姆斯河煤矿服务公司的总裁 。过去六个月，他的公司解雇了725名工人 。他担心新的规定会让这个原本已经经济萧条的地区更加艰难 。
“要理解，这个行业有1,000，2,000，3,000人。当这里受到华盛顿特区制定的条例的经济影响时——这些条例完全不理解会对当地居民造成什么影响，对于那些每天起床就去上班的人有什么影响，将来对于他们的家人会有什么影响 。这是错误的 。”
David Doniger是美国最大的环保组织自然资源保护协会的气候政策专家。他表示，将碳排放作为污染物进行控制是环保局的责任 。他希望环保局能够制定新的法规，让美国步入更加清洁的能源环境 。
