向污染宣战要打好三大战役

正今年的政府工作报告提出,我们要像对贫困宣战一样,坚决向污染宣战。坚决向污染宣战,是破解我国生态环境难题的必然选择。一段时期以来,我国经济社会发展付出了过大的资源环境代价。2013年,七大流域国控断面中,劣Ⅴ类的仍占10.8%;按照环境空气质量新标准开展监测的74个城市中,细颗粒物(PM2.5)年均浓度为72微克/立方米,超过二级标     

治理环境污染需要新思路

持续了“一生一世”（2013～201 4）的雾霾,在吞噬环境发展的空间,在消耗人们的耐心,也在考验顶层设计者的智慧。党和国家领导对治理雾霾十分重视,习近平总书记特别选择在雾霾天视察北京胡同,和老百姓同呼吸共命运。李克强总理在国务院常务会上,一连向国家环保部长提出了数十问。在全国两会政府工作报告中还提出,要像对贫困宣战一样,坚决向污染宣战。     

向污染宣战

正编者按"六·五"世界环境日到来之前,中国人接到了一个个环境欠账单:空气污染告急、水污染告急、土壤污染告急急………面对满目污秽的山山水水水,不再会有人没心没肺深情款款地唱出出"一出条大河"。今年的"六·五"世界环境日不再是个敲锣打鼓喧闹的日子,而子而是一个反思的日子子,一子个战前动员的日子——向污染宣战,否则否则国将不国国。但即使形势如此严竣,我们仍充满必胜信心。因因为正如鲁迅所说说:"我们     

面对未来向污染宣战

＂我们要像对贫困宣战一样,坚决向污染宣战。＂今年两会,李克强总理将治理污染提高到和反贫困战役同样的高度,彰显出政府治理污染、保护环境和推动生态文明建设的块心、胆略与气魄。人类的经济和社会活动不可避免地会造成环境污染,问题是在于,如何控制和解决污染的速度,使其能够被限制在自然环境消解的闯值之内,既确保人类生存、生产与生活发展的必需,又不至于造成环境污染和生态破坏。实现人类活动与自然生态的和谐共处。无可否认的是,这是一个所有人都认同然而却始终难见其效的理想。     

来自两会上的环境报告之四:用“硬措施”挽救中国的美丽

正许多代表委员认为,中国共产党的第一大功劳,就是向贫困宣战,解决了十几亿人的温饱问题。现在,李克强总理把向污染宣战提到向贫困宣战的高度,说明党和政府要把让十几亿人有质量的生活作为今后最大的目标,这是一种勇气,也是一种远见卓识。

来自两会上的环境报告

正"我们要像对贫困宣战一样,坚决向污染宣战","不是说向老天爷宣战,而是要向我们自身粗放的生产和生活方式宣战"——李克强总理的这两句话,成为今年两会上环保的最强音。而生态环境保护也无疑成为今年两会上最引人瞩目的话题之一。据了解,今年关于环保的提案议案数量为历年最多,所涉及的内容和领域也为历年最广。有的代表委员多年不辍地提出关于环保的提案和建议。我们有理由相信,在代表委员的监督下,

如何抓住孩子让环保走进家庭

从家庭方面讲，关于环保知识人们又了解多少，观念上又重视多少呢？尤其是农村家庭。我采访了很多人，他们都觉得太忙，没有闲暇关心这些。谈到环保，人们表现的也很茫然，当然他们也知道沙尘暴、也知道水灾、台风和旱情，但成因就不得而知了。具体到人们的生活，什么节约水电、废物利用、垃圾的分类回收，农村人尤其是那些围着锅台转的主妇们，根本不明白为什么要这样做。因此，我认为，环保教育不在于向家庭普及些什么，如何普及才是最重要的！孩子，是纽带，是让环保走进家庭的一条有效途径。但是，让环保走进家庭，不能像布置语文作业，…     

Degradation of oilwell cement due to exposure to carbonated brine

The growing interest in geologic carbon sequestration has highlighted the need for more data on how well cements react to CO₂ exposure. This paper describes a series of experiments that was conducted to examine the effects of flowing carbonated brine on well cements. Class H cement pastes were exposed to the ranges of temperature (20–50 °C) and pH (2.4–5) characteristic of geosequestration conditions at a depth of about 1 km. The exposed cements and the reactor effluents were analyzed using multiple techniques including optical microscopy, X-ray diffraction, EPMA, and ICP-OES. The results showed that if the solution was pre-equilibrated with calcium carbonate, as would be expected in a limestone formation, there was no detectable attack. However, under the pH and temperature conditions to be expected in a sandstone formation, the initial rate of attack was on the order of millimeters per month. The outer layers of the cements reacted under sandstone-like conditions were fully degraded based on the results of the XRD and EPMA analyses. Inside the degraded layers there was a calcium carbonate-rich layer, a layer depleted of calcium hydroxide, and an unreacted cement core. The rate of degradation of the cement in these experiments was controlled by the rate of dissolution of the calcium carbonate-rich layer, after its formation, and diffusion through the fully degraded layers.     

Listening to local voices: Tuvaluans respond to climate change

Climate change has become a permanent feature on the global media scene and in the decision-making of policy makers. The voices of academics, scientists, politicians and commentators dominate the climate change debate, yet local knowledges and beliefs, local realities, as well as local voices and actions are essential elements of navigating the way forward. Drawing on Paton's postgraduate research, this paper broadens the current dialogue by providing a platform for grassroots Tuvaluan voices to enter the climate change debate. It explores their local realities, knowledges and beliefs, and captures what Tuvaluans hold dear – factors which must play a central role in decision-making processes. To ensure the local population is fully mobilised, it will be argued that processes for engaging local voices must build on existing forums for engagement.     

Building a model of commitment to the natural environment to predict ecological behavior and willingness to sacrifice

We examined the connection between individuals’ relationships with the natural environment and their environmental behaviors with a focus on commitment to the environment, defined as psychological attachment and long-term orientation to the natural world. Commitment is theorized to emerge from structural interdependence with the environment and to lead to pro-environmental behaviors. Close relationships research has identified three key antecedents to commitment (satisfaction, alternatives, and investments). We developed environment-specific measures of these constructs, and factor analysis verified three distinct factors. A path analysis revealed that satisfaction with the environment and investments in the environment, but not alternatives to the environment, predicted commitment to the environment. Moreover, commitment mediated the effects of satisfaction and investments on general ecological behavior and willingness to sacrifice for the environment. In regression analyses, commitment predicted general ecological behavior and willingness to sacrifice for the environment, even when controlling for ecological worldview, inclusion of nature in the self, connectedness to nature, and environmental identity. Individuals who are satisfied with and invested in the natural world are likely to be committed to the environment and act with the well-being of the environment in mind.     

Oil to 2000

Current surplus oil production capacity had its origins in the price increases of the 1970s. Those increases encouraged both energy conservation and the entry of new producers. Recent increases in oil demand reflect the belief among energy users that in real terms in the long term, prices will be stable. There is good reason to believe that this will be so, even at the current rate of increase it will be 15 years before demand matches current capacity. Given that situation it is difficult to see OPEC following any other pricing policy than the one currently in place. In the meantime market prices will further encourage vertical integration.
