温室里的囚徒——对全球变暖问题的经济学思考

温室气体排放引起的全球变暖不仅导致当前全球气象灾害频繁发生,而且危及人类社会的可持续发展。在温室气体减排合作过程中,面临囚徒困境的博弈各方在环境恶化的情况下会采取合作的态度;但根本的解决之道还在于明确温室气体排放的产权制度,提高使用效率并避免过度使用的＂公地悲剧＂。     

科学认识、国际政治利益与环境保护角力下的《京都议定书》

The Story of Two Big Chimneys: A Frame Analysis of Climate Change in US and Chinese Newspapers

Despite mounting research on how the news media portrayed climate change in developed countries, disproportionately little attention was paid to one of the top greenhouse gas emitters in the world—China. This study systematically examined and compared how the US and Chinese newspapers portrayed climate change. An analytical framework, grounded in framing research traditions, took into account both theoretical and practical challenges in frame analysis by creating a hybrid structure of interlocked generic and issue-specific frames. The results showed both convergent and divergent pictures from the two countries’ newspapers shaped distinctly by the sociopolitical realities in both countries. The research also cautioned against making simplistic explanations of the results and offered culturally informed interpretations. A discussion on better research focus and design was offered for future research in this avenue.     

When Poststructural Theory and Contemporary Politics Collide—The Vexed Case of Global Warming

Policy debate about global warming has been framed in the public sphere in the manner of most political topics, as a matter of “skeptics” and “supporters,” making it very difficult for many US publics to know what to believe. This essay critically reads a preeminent public policy debate—that of global warming—with a twofold purpose. I first array the extensive commercial and political efforts to manipulate public information about global warming in order to illustrate that this debate is a “disingenuous” or “pseudo-controversy,” which can be seen in the asymmetrical resources, motives, and authority behind the scenes. Second, I ask what institutional and discursive conditions have enabled this moment, in which the ideals of academic freedom and protocols of scientific inquiry hold precarious authority in the public arena, and argue that contemporary critical perspectives on knowledge and truth have been co-opted in public discourse, making it more difficult to intervention in commercial and political efforts to obfuscate and mislead US publics.     

低碳经济:未来中国可持续发展之基础——兼谈中国相关法律与政策的完善

低碳经济日益受到世界各国关注的原因除了全球气候变暖的事实外,也符合各国经济利益上的追求目标。我国国内外的现实显示了我国加快发展低碳经济的迫切性,同时也决定了中国的低碳经济之路依然面临着诸多压力与挑战。加快完善中国相关的法律与政策,建立一个有利于低碳经济发展的政策法律体系对于推动低碳经济的发展是不可或缺的。

Discourse in the Balance: American Presidential Discourse About Climate Change

According to NASA (2018), 17 of the 18 hottest years on record have occurred since 2000. In an effort to better understand the political communication of American leaders surrounding this environmental exigency, I systematically examined invocations of climate change in the spoken communications of presidents George H. W. Bush, Bill Clinton, George W. Bush, and Barack Obama. I identified three discursive approaches that were likely to appear in these communications: a general environmental emphasis, foregrounding, and sidestepping. Results from a content analysis showed these presidents were most likely to employ foregrounding, with a focus on the economy. Democrats were more likely to employ a general environmental emphasis, while the Republicans were more likely to sidestep the issue of climate change. In addition, presidents were more likely to emphasize national security as time passed. Implications are discussed for public understanding about climate change and future policy when presidents focus on economic matters and national security.
