David Keith (scientist)

David W. Keith Gordon McKay Professor of Applied Physics for the Paulson School of Engineering and Applied Sciences (SEAS) and Professor of Public Policy for the Harvard Kennedy School at Harvard University . ^[1] He is ook executive chairman of Carbon Engineering . ^[2]

Keith’s research has spanned verschillende areas, zoals climate-related technology assessment and policy analysis , technological development, atmospheric science, and physics.

Geo-engineering

Keith has worked on solar geoengineering since 1992-when he wrote one of the first assessments of the technology and its policy implications. ^[3] Since Keith’s 1992 paper, welke introduced a structured comparison of cost and risk, and a later review paper dat first DESCRIBED the moral hazard and set geoengineering in the post-war history of weather control, Keith has SOUGHT answers to the questions:

• How unequal? – First quantitative analysis of regional inequality or solar geoengineering. ^[4]
• How to-reducing risks? – New method to-reducing the amount of sulfur needed for a bepaald radiative Forcing; ^[5] and, a novel class of self-levitated Particles That might limit ozone loss. ^[6]
• What does the public think? – First large-scale survey of public perception. ^[7]
• How to regulate? – Proposed two-threshold system dat combineert a deployment moratoria with a pathway for gereguleerde small-scale research. ^{[8] [9]}
• How to evaluate trade-offs? – Early economic analysis of optimal Decisions under uncertainty and a value-of-information analysis while Supervising the first economics PhD to focus on geoengineering. ^{[9] [10]}

In 2013, Keith released a book, A Case for Climate Engineering, Detailing a controversial strategy for slowing climate change. The book’s publisher’s blurb states: “A leading scientist lung Concerned about climate change, David Keith offerings no naive proposal for an easy fix to what is perhaps the must challenging question whether our time. But he argues dat after decades prolongation welke very little progress has leg Made in Reducing carbon emissions, we must put climate engineering on the table and consider it Responsibly. … This book zorgt a clear and accessible overview of the costs and risks, and how climate engineering Might fit JSON a larger program for managing climate change. ” ^[11]

He has ook Contributed to assessments dealing with geoengineering. Keith was a member of the working group for UK Royal Society’s 2009 report ^[12] as well as the Bipartisan Policy Center Report. ^[13]

Public comments

In 2010, Keith testified voordat committees of the US Congress and the UK Parliament. He Presented to US National Academy meetings in 2000, 2009 and 2013 and was coauthor of the geoengineering sub-chapter (WG 2, 4.7) of the Third IPCC Report and served AR5. ^[9]

Keith has leg featured on the Discovery Channel, ^[14] did an interview on BBC News HARDtalk in November 2011, ^{[15] [16]} has participated in TED talks in September 2007, ^[17] participated in a debate at the Royal Geographical Society in 2009, ^[18] and Appeared in a documentary on geoengineering Currently under production. ^[10] He’ll be promoted his geoengineering idea to slow climate change by Spraying reflective Particles withinto the upper atmosphere on The Colbert Report. ^[19]
