David Keith (physicist)

from Wikipedia, the free encyclopedia

David W. Keith is an American Professor of Applied Physics in the Gordon McKay Laboratory of the Paulson School of Engineering for Applied Sciences (SEAS) at Harvard University and Professor of Public Policy for the Harvard Kennedy School at Harvard University. He is also the CEO of Carbon Engineering .

Keith's research spanned multiple areas including the assessment of climate-related technologies such as policy field analysis , engineering development, atmospheric sciences and physics.

education

Keith studied physics at the University of Toronto , where he received his BS in 1986. In 1991 he received his PhD in experimental physics from the Massachusetts Institute of Technology .

Geo-engineering

Keith has worked in solar geoengineering since 1992 when he wrote one of the earliest assessments of the technology and its policy implications. Since Keith's 1992 article that introduced a structured comparison of costs and risk , Keith has been searching for answers to the questions in a later review article that first described moral hazard and geoengineering in post-war weather control history:

  • How unequal - first quantitative analysis of the regional inequality of solar geo-engineering.
  • How can you reduce risks? - New method to reduce the amount of sulfur required for a given radiative forcing; and a novel class of airborne particles that could limit ozone loss.
  • What does the public think? - First large-scale public perception survey.
  • How to regulate - Proposed two-threshold system combining a moratorium on deployment with a way of regulating research on a small scale.
  • How do I evaluate compromises? - Early economic analysis of optimal decisions under uncertainty and an analysis of the information value under supervision of the first PhD in economics. focus on geoengineering.

In 2013, Keith published a book called A Case for Climate Engineering , which outlines a controversial strategy for slowing climate change. The editor's blurb reads: "David Keith is a leading scientist who has long been concerned about climate change. He does not offer a naive suggestion for a simple solution to perhaps the most difficult question of our time. But he argues that after decades who have made very little progress in reducing CO 2 emissions, put air conditioning on the table and need to think responsibly ... This book provides a clear and easily accessible overview of the costs and risks, as well as how climate engineering fits into a broader program to address climate change.

He has also contributed to reviews in the geoengineering field. Keith served on the working group on the UK Royal Society's 2009 report and the bipartisan Policy Center Report.

Keith is the co-director with Gernot Wagner , of the Harvard Solar Geoengineering Research Program, which was founded in 2017.

Public comments

In 2010, Keith testified before committees of the US Congress and the UK Parliament. He lectured at the meetings of the US National Academy in 2000, 2009 and 2013, co-authored the Geoengineering subchapter (WG 2, 4.7) of the IPCC's Third Assessment Report and also contributed to the Fifth Assessment Report .

Keith was featured on the Discovery Channel, interviewed on BBC News HARDTalk in November 2011, participated in the TED Talks in September 2007, participated in a debate at the Royal Geographical Society in 2009, and appeared in a documentary on geoengineering. He also discussed his geoengineering idea in the Colbert Report on Comedy Central.

Further work

Keith is skeptical of the benefits of fuel cell vehicles using compressed hydrogen. He is optimistic about solar energy.
