气候变化面临着大量的不确定性,因此不确定性就成为气候变化经济学研究的一个重点和难点。传统的成本收益方法都假定气候敏感性服从标准正态分布,并在此基础上设定效用函数和损失函数。斯特恩对这些方法提出了批评,指出气候变化问题不适用于边际分析。继《斯特恩报告》之后,以哈佛大学的魏茨曼为代表的经济学家对气候变化经济学中的结构性不确定性展开研究。魏茨曼指出气候敏感性应服从厚尾分布,这一观点既具有气候自然科学方面的基础,也得到了众多经济学家的认可。而传统的成本收益方法由于假定气候敏感性服从瘦尾分布,因此对气候敏感性、效用函数和损失函数的设定都存在偏误,从而低估了未来气候灾难发生的可能性及其可能造成的损害的程度。围绕厚尾分布的观点,魏茨曼提出并证明了悲观定理,这一定理表明人们为了避免未来的气候灾难,愿意牺牲当前部分甚至全部的消费,从而在理论上揭示了不确定条件下气候变化公共决策的理论依据。他指出当前的减缓投资相当于是为了避免未来气候灾难的保险,而当前减排行动所依据的正是预防原则。预防原则的来源,则是气候灾难这种小概率、大影响事件所导致的恐惧因素或者模糊厌恶。实证研究的结果表明,依据厚尾分布改变气候敏感性和损失函数,未来气候灾难可...的翻译是:

FCC Data: 9 out of 10 Wireless 9-1-1 Calls in D.C. Lack Accurate Caller Location Information
July 10th, 2014
Data Obtained via Freedom of Information Act Shows Urgent Need for Indoor Location Accuracy Requirements Proposed by FCC
WASHINGTON, D.C. – July 10, 2014 – New data obtained from the U.S. Federal Communications Commission (FCC) through the Freedom of Information Act (FOIA) show that nine out of ten wireless 9-1-1 calls made in D.C. in the first half of 2013 were delivered without the accurate location information needed to find callers who are lost, confused, unconscious or otherwise unable to share their location.
According to data filed with the FCC by the D.C. Office of Unified Communications last fall, just 10.3% of the wireless calls made to the District’s 9-1-1 communications center from December 2012 to July 2013 included the latitude-longitude (or “Phase II” location) needed to find a caller.
Of the 385,341 wireless calls made over that period, just 39,805 had that “Phase II” information, while the remaining “Phase I” calls only showed the nearest cell tower, an area too broad to be useful for emergency responders.
“These results reveal an alarming public safety crisis,” said Jamie Barnett, former Chief of the FCC’s Public Safety and Homeland Security Bureau and Director of the Find Me 911 Coalition. “When nine in ten emergency callers in our nation’s capital cannot be located on wireless phones, we know that the requirements for location accuracy must be updated immediately.
Thankfully, the FCC has proposed a strong new rule to help find wireless callers in need, both indoors and outdoors, and this should eliminate any doubt about the importance of rapid adoption of that rule.”
The location technology currently used by most wireless carriers (called A-GPS) depends on a direct line of sight to satellites, so it often fails in indoor locations or dense urban areas like the District.
The FCC recently proposed a new rule () to address this issue by requiring wireless carriers to provide accurate location data for indoor calls within two years.
According to the FCC, the proposed rule could save an estimated 10,000 lives a year through faster response times.
“The nation’s capital faces unique security issues, and it’s critical that 9-1-1 callers in DC be quickly located in an emergency,” continued Barnett.
“Unfortunately, the safety of our residents and visitors is being put at risk on an ongoing basis when 9-1-1 cannot identify their locations to send help.
This failure to provide location information is a serious danger anywhere, but especially with the added security threats faced by those who visit, live, or work in the nation’s capital.”
Other data provided by the FCC offered a breakdown by carrier of wireless 9-1-1 calls in DC for a different period of time, from July 1, 2013 to September 30, 2013.
That data showed significant variation for accurate “Phase II” information among carriers:
Total Calls
(7/1/13 -9/30/13)
Phase II Calls
(7/1/13 -9/30/13)
Percent of Calls with Accurate Location Info
Many of the nation’s leading public safety and public health organizations have submitted comments in support of the proposed FCC rule, including the International Association of Chiefs of Police, National Sheriffs’ Association, International Association of Fire Fighters, International Association of Fire Chiefs, National Association of EMS Physicians, National Association of EMTs, National EMS Management Association, American College of Emergency Physicians, National Association of Regulatory Utility Commissioners, and National Public Safety Telecommunications Council.
In addition, a survey released in April of 1,014 managers and employees from the call centers that handle 9-1-1 calls found that 99 percent supported the FCC’s proposed requirements for indoor location accuracy within two years, and another 99 percent said the adoption of that rule was “critically” or “very” important for public safety in their communities.
“The FCC has put forward an outstanding proposed rule that will save more than 10,000 American lives each year,” concluded Barnett. “Public safety leaders should continue to stand firm with their members in support of that rule and not be swayed by carrier rhetoric and empty promises of some future solution.”
The Find Me 911 Coalition submitted its FOIA request to the FCC on May 15, 2014.

About the Find Me 911 Coalition
is an effort supported by more than 195,000 individuals, as well as national and local organizations. The individuals and organizations represent a broad range of 911 operators and first responders – emergency medical services personnel, fire fighters and police.
Find Me 911 seeks to ensure that the Federal Communications Commission (FCC) move forward quickly to establish a reasonable, measurable level of location accuracy for emergency calls made indoors, enabling first responders to locate emergency calls from wireless phones from all locations rapidly and efficiently.
