星际飞船vs.地球太空船

Eric Steig & Ray Pierrehumbert

我(埃里克)最喜欢的一本旧书是星际飞船和独木舟by Kenneth Brower It's a 1970s book betway体育手机版about a father (Freeman Dyson,theoretical physicist living in Princeton) and son (George Dyson,hippy kayaker living 90 ft up in a fir tree in British Columbia) that couldn't be more different,然而,他们的创意和才华却惊人地相似。I started out my career heading into astrophysics,我也是一个狂热的皮划艇爱好者,我在不列颠哥伦比亚省长大。雨林在我的后门。所以我想我知道是什么驱动了这些人。Yet I've never understood how Freeman Dyson became such a climate contrarian and advocate for off-the-wall biogeoengineering solutions like carbon-eating trees,something we've以前写过betway体育手机版.

事实证明,布劳尔也有同样的想法,最近文章在The Atlantic,he speculates on the answer."How could someone as smart as Freeman Dyson," writes Brower,"be so wrong betway体育手机版about climate change and other environmental concerns..?"

Why Levitt and Dubner like geo-engineering and why they are wrong

提交如下: -加文,2009年10月18日

Many commentators have already pointed out dozens of misquotes,misrepresentations and mistakes in the ‘Global Cooling' chapter of the new bookSuperFreakonomics作者:Ste[ph_v]Ens Levitt和Dubner(见Joe Romm(parts III三角肌UCS克鲁曼for details.迈克尔·托比斯有一个good piece论适应与地质工程的区别)。不幸的是,Amazon has now turned off the ‘search inside' function for this book,但是你可以自己阅读相关章节在这里(通过布拉德德龙)。However,不是简单地列出别人已经发现的错误,我将集中讨论为什么这一章可能是在第一时间写的。(对于某些地质工程背景,read our previous pieces:气候变化美沙酮?Geo-engineering in vogue,《大西洋月刊》重新设计地球“这篇文章引用了我们自己的雷皮埃尔的很多话。”

A biased economic analysis of geoengineering

客人评论艾伦·罗伯克–罗格斯大学

Bjorn Lomborg气候共识中心just released an un-refereed report on geoengineering,An Analysis of Climate Engineering as a Response to Global Warming,by J Eric Bickel and Lee Lane.The "consensus" in the title of Lomborg's center is based on a meeting of 50 economists last year.允许经济学家决定社会对全球变暖的正确反应的问题是,他们的分析仅仅基于他们自己对不同战略的成本和收益的量化。在这份报告中,discussed below,they simply omit the costs of many of the potential negative aspects of producing a stratospheric cloud to block out sunlight or cloud brightening,and come to the conclusion that these strategies have a 25-5000 to 1 benefit/cost ratio.第二作者为美国企业研究所工作,一个游说团体一直是全球变暖的头号否认者,不足为奇,但现在他们支持解决多年来一直声称不存在的问题。

Climate change methadone?

提交如下: — gavin @ 20 August 2008

在许多论坛上,地球工程学越来越多地被讨论(不再那么索托了)。当前的兴趣浪潮被保罗·克鲁森2005年的社论and a number of讲习班commentary)高调advocacy.But most of the discussion has occurred in almost total ignorance of the consequences of embarking on such a course.

现在,越来越多的人开始发表相关的研究报告——清楚地显示了继续研究这一主题的价值——本周,在Jgr大环境下,一项重要的研究发表了。博洛克等使用一个耦合的GCM和相互作用的气溶胶,看看如果他们注入大量的SO会发生什么。(硫酸盐气溶胶的前驱体)进入热带或北极平流层。这是最常被谈论的(也是最可行的)地质工程思想,betway体育手机版基于大型热带火山爆发(如Mt.Pinatubo in 1991).底线?这不是万能药。

拯救世界!Earn $25 million!

客人评论来自Juliane Fry,UC Berkeley

On February 9,The Virgin Group chairman Sir Richard Branson announced a $25 million prize for anyone who can demonstrate "a commercially viable design which results in the removal of anthropogenic,atmospheric greenhouse gases so as to contribute materially to the stability of Earth's climate." At the press conference announcing this "维京地球挑战奖“Branson was joined by Al Gore,and the panel of judges for the competition includes additional climate change celebrities: James Hansen,James Lovelock,Tim Flannery还有Crispin Tickell先生。

竞争的目标是找到一种每年至少从大气中去除10亿吨碳的方法。很有意思的一点是,看看什么想法出现在Scrub Co的前面。从大气中。2500万美元应该能激发创造力!(当然,once working should bring in a significant amount of carbon offset money).A ruckus was caused last year when discussion of injecting SOinto the stratosphere to form reflective sulfate aerosols to mask global warming made scientists feel they needed to state their position on this controversial,poorly understood proposal.During the discussion,a New York Times feature (described在这里)讨论了各种“地球工程学”的替代方法,以施加冷却效应来掩盖全球变暖。At least in this case,我们不想在大气中增加新的不确定因素,更确切地说,删除我们添加的内容。

有一篇有趣的文章NY Times本周将讨论全球变暖问题的地球工程解决方案。故事围绕着一篇保罗·克鲁森(诺贝尔化学奖获得者)写的论文展开,该论文涉及到有意在平流层中添加硫酸盐气溶胶以增加反照率和冷却地球,类似于火山的自然效应。betway体育手机版这篇论文发表在《气候变化》杂志上。但不寻常的是,有一套其他科学家的评论文章。This is because geo-engineering solutions do not have a good pedigree and,不管他们的优点或真正的潜力,are often seized upon by people who for various reasons do not want to reduce greenhouse gas emissions.However,these ideas keep popping up naturally since significant emission cuts continue to be seen as difficult to achieve,所以应该公平考虑。After all,if there was a cheaper way to deal with the CO问题,甚至是一种争取时间的方式,我们不应该接受吗?更多的
