SuperFreakonomics:用Freakonomics挑战Climate Change

Oct. 20 (Bloomberg)

superfreakonomics.coverSuperFreakonomics的两位作者

Steven Levitt, professor of economics at the University of Chicago

Stephen Dubner,journalist

他们合作第一本书“Freakonomics,” 销售了4百万册. 这次两位再度出山把箭头指向了"白热化"的Climate Change.

书中引用了 Ken Caldeira, a climate scientist at Stanford University的一些观点,但有些误传.

"Carbon dioxide is the right villain,insofar as inanimate objects can be villains."

By Ken Caldeira

多元凶Multiple Villains

“SuperFreakonomics” never identifies the “right villain,” so I called Dubner and asked. “I don’t think anybody knows for sure,” he told me. Then he acknowledged that the chapter’s most newsworthy claim “could have been better phrased, as ‘carbon dioxide is not the only villain.’”

nhshgl 重提全球变冷Global Cooling

They dismiss global warming as a “religion” and rehash the so-called “global cooling” scare of the 1970s, a favorite skeptic myth.

They trumpet the “little-discussed fact” that the average global temperature has decreased in recent years.

发射SO2Shooting Sulfur Dioxide

One would shoot millions of tons of sulfur dioxide 18 miles into the air to artificially cool the planet.

In chapter five, the authors:

Atmospheric science: Monsoon madness

J. Geophys. Res. doi:10.1029/2009JD011733 (2009)

The severity of the east Asian summer monsoon, which affects more than 1 billion people, may be better forecast by analysing the North Atlantic Oscillation (NAO). This describes a large-scale system in which atmospheric pressure rises and falls in a see-saw motion from the polar to the subtropical region.

The monsoon's strength has been linked to the El Niño and La Niña cycles, but the NAO connection may further improve predictions, say Zhiwei Wu of the Chinese Academy of Sciences in Beijing and colleagues.

By combining data on global precipitation and atmospheric circulation with other indices of atmospheric activity, the researchers found that changes in the spring NAO can influence how strong or weak the monsoon gets later in the year.

翻墙成功

 

今天偶得chinagwf.org的帮助,成功翻墙。

过去一直以来,自以为是翻墙好手,由于无界,torsixxs.org两大利器屡试不爽。不过随着国庆的到来,一切都开始失策。无界,tor都被封锁,新机器上的Vista 64bits对IPV6市灵时不灵,sixxs.org有时候用不起来。

到现在觉得突然眼前豁然开朗了,因为我翻墙成功了。

1 The Free VPN

目前我运行最好的,速度也过得去的是world secure channel提供的thefreevpn,目前免费账号提供两组服务器,一组为两台美国服务器(其中一台可以连接Hulu),另一组为两台英国服务器。免费账户除了人数连接上限外,没有其他限制(可能我用的时间不太长,2小时的穿墙)。安装很简单,不过会添加一个没有微软数字认证的虚拟网卡,如果有人因为这个导致系统不稳定那就没办法了。
