© 2019 TIME USA, LLC. that's how David Keith sums up his contribution to climate-change research. The Harvard scholar is interested in both the scientific and the public policy questions that bear on climate change and has a hand in a surprising range of projects related to climate and energy. Department of Physics. Keith has been an advisor to Gates since 2005. To predict aerosol size distributions we apply microphysical parameterizations of nucleation, condensation and coagulation to simulate an aerosol plume generated via injection of calcite powder or sulphate into a stratospheric wake with velocity and turbulence simulated by a three‐dimensional (3D) fluid dynamic calculation. David Keith has worked near the interface between climate science, energy technology, and public policy for twenty five years. While I have specialized tools for optical design and finite element analysis, Mathematica is my Swiss Army Knife. We apply the model to predict the aerosol distribution that would be generated by a propeller wake in the Stratospheric Controlled Perturbation Experiment (SCoPEx). In 1998, [physicist and geoengineer] David Keith and I were at a meeting with Lowell Wood talking about ways to address climate change. The fact that geoengineering schemes — intervening in the climate by shielding the earth's surface from trillions of watts of sunshine, or sucking billions of tons of carbon dioxide out of the atmosphere — have started to get serious attention from policymakers is in large part due to Keith's work looking at what such tools can do, and what it might mean to use them. "It can't be a significant contributor to solving the (climate) problem," agrees Harvard physicist David Keith,adding the supply chain isn't big enough … David joined MPC in 2019 after earning his Master’s degree in Radiation Health Physics from Oregon State University. Lead author Amanda S. Adams was formerly a postdoctoral fellow with Keith and is now assistant professor of geography and Earth sciences at the University of North Carolina at Charlotte. David Miller (B. There is extreme arrogance without a shred of oversight or accountability. David Keith talks fast and takes stairs two steps at a time, as though impelled by a sense of urgency. Governing Geoengineering. The experiment began as a partnership between atmospheric chemist James Anderson of Harvard and experimental physicist David Keith, who moved to the university in 2011. David Keith, a professor of applied physics at Harvard’s School of Engineering and Applied Sciences (SEAS) and a professor of public policy at Harvard’s Kennedy School of Government, is the founder of Carbon Engineering. That didn’t deter David Keith, a physicist at Harvard University who co-founded a company focused on DAC. In … We also gathered closed-form survey results from 19 experts with >10 publications on SG. While it excites him as a technologist and fascinates him as a policy wonk, he remains an analyst, not an advocate. Read more The thing about tools, he says, "is not that you have to use them: it's that you have to understand them.". David Keith never expected to get a summons from the White House. Sir David Melville, CBE, FInstP (born 4 April 1944) is a British physicist, academic, academic administrator, and public servant. We performed face-to-face interviews using formal expert elicitation methods with 13 US and 13 Chinese climate experts randomly selected from IPCC authors or supplemented by snowball sampling. His observation of high energy positrons has provided the first conclusive evidence for the existence of galactic dark matter. Sc., St. Andrews, Ph.D., Heriot-Watt) is the W. M. Keck Professor of Electrical Engineering, and Professor by Courtesy of Applied Physics at Stanford University. David Keith may also refer to: David Keith (drummer) (born 1973), American drummer, composer, and producer; David Keith (racing driver) (1973–2020), American racing driver; David Keith (scientist), physicist and Professor of Public Policy at Harvard University Before Stanford, he was with Bell Laboratories from 1981 to 1996, as a department head from 1987. Climate experts chose far less SG deployment in future climate policies than did SG experts. Harvard physicist David Keith theorizes that by 2070, 50 customized jet planes distributing a million tons of sulfur a year could halve the rate at which Earth is warming. The report’s authors also call for a comprehensive research program that would involve all federal agencies conducting climate research. "One of the inherent challenges of wind energy is that as soon as you start to develop wind farms and harvest the resource, you change the resource, making it difficult to assess what's really available," says Adams. "People have often thought there's no upper bound for wind power -- that it's one of the most scalable power sources," says Harvard applied physicist David Keith. On Tuesday, February 17, David Keith will present Patient Geoengineering, as part of our monthly Seminars About Long-Term Thinking. David Miller, by courtesy Professor of Applied Physics and an expert in photonics, ... Stanford physicist’s quest for the perfect keys to unlock the mysteries of superconductivity. For decades Z-X Shen has ridden a wave of curiosity about the strange behavior of electrons that can levitate magnets. David Keith (born 1954) is an American actor and director. We compare their judgments on climate change, SG research, governance, and deployment. Soon he was working on nitty-gritty climate-modeling problems while learning economic and policy analysis. Reduction of specific process uncertainties relevant to the distribution of aerosol in a turbulent stratospheric wake is necessary to support informed decisions about aircraft deployment of this technology. Dr. David Underhill is a Macarthur Grant recipient and a very successful physicist, with Leonard excited to be working with him. Yuri Arcurs/Getty Images. That breadth has helped him communicate climate concerns to the often skeptical energy industry; it's also part of why he is listened to by people like Bill Gates, who relies on meetings organized by Keith to stay up-to-date on climate science. Keith is, in my opinion, the epitome of what is wrong with an unfortunately high percentage of the scientific community. From saving wild mountain rivers in China to measuring the Arctic's icy expanse, from protecting the lush forests of Africa to conducting a feisty online debate, our green heroes are informed by this simple notion: We can all make a difference. Climate work promised a greater opportunity to do good while at the same time throwing up what ambitious physicists always want most: questions no one yet knows the answers to. "It's about tools." In contrast to existing literature that often stress factors that might differentiate China from western democracies on SG, we found few significant differences between quantitative judgments of US and Chinese experts. Governing Geoengineering Sustainability Now. It sounds quite modest, and Keith, a balding but boyish 45-year-old professor at the University of Calgary, can be disarmingly modest, in an intense, very bright, very Canadian sort of way. Oliver Morton is the former Chief News and Features Editor of Nature; he is writing a book about geoengineering. He was the Vice-Chancellor of Loughborough University from 1994 to 2005, and the Master of Churchill College, Cambridge from 2006 to 2014. Since at least 2010 Gates has called for manmade dimming of the sun. Keith is keen to stress that geoengineering is no alternative to reducing carbon emissions, but insists that it should be researched as a possible aid. (About $10 million is spent worldwide today, says David Keith, a physicist and faculty director for the Harvard solar geoengineering program.) David Keith, a Harvard physicist involved with the project, said he doubted that anyone knew how widespread opposition was in Sweden. ", That balance helps. IN JUNE, climate scientist David Keith and his neighbors in Calgary, Alberta, were ripping carpets and drywall from their flooded homes — again. “In solar geoengineering research, introducing sulfuric acid into the atmosphere has been the only idea that had any serious traction until now,” said David Keith, the Gordon McKay Professor of Applied Physics at SEAS and professor of public policy at … I have been using Mathematica since Version 2.1. He is currently the Gordon McKay Professor of Applied Physics in the School of Engineering and Applied Sciences (SEAS) at Harvard University and Professor of Public Policy at the Harvard Kennedy School.

Both expert groups supported greatly increased research, recommending SG research funding of ~5% on average (10th–90th percentile range was 1–10%) of climate science budgets compared to actual budgets of <0.3% in 2018. He took first prize in Canada's national physics prize exam, won MIT's prize for excellence in experimental physics, and was one of TIME magazine's Heroes of the Environment 2009. He serves as a Diagnostic Radiological Physicist in southwest Michigan. Dr. Gablehauser said if David wanted to set something up in the photomultiplier lab, Leonard would be able to give him a hand. Physicist David Keith, who has been working on technologies to block sunlight to slow global warming, argues that such efforts need to remain … To arrive at the edge of the world's knowledge, seek out the most complex and sophisticated minds, put them in a room together, and have them ask each other the … David Keith A critical look at geoengineering against climate change ... Schwartzberg’s lens. But early success in pure physics (his graduate project, supervised by a professor noted for his mentoring of future Nobelists, was a long-awaited experimental breakthrough in atomic optics) did not satisfy him.

David Keith Professor of Applied Physics and Public Policy, Harvard University Verified email at harvard.edu Ken Caldeira Carnegie Insitution for Science, Dept. The plasma physicist runs a small company with a big idea for … US and Chinese experts differed on topics, such as desired climate scenario and the preferred venue for international regulation of SG, providing some insight into divergent judgments that might shape future negotiations about SG policy. Keith is a physicist, with a physicist's love for looking deep into causes and for mathematically quantifying effects. Responsible for User Experience research and requirements gathering on new application development projects and service offerings across both administrative and educational audiences. I am now retired, but continue to be interested in optics, physics, and mathematics. We find that injecting 0.1 g s. Expert judgments on solar geoengineering (SG) inform policy decisions and influence public opinions. Before completing his Master’s degree, David enjoyed teaching physics for five years in northeast Wyoming. David Kestenbaum We hear two stories of everyday life which are more easily understood if one knows some of the laws of physics, specifically the Mediocrity Principle and the Casimir Effect. "While he's got informed and strong opinions," Gates says, "he's also incredibly open-minded, pointing out the unknowns in his opinions and just as readily pointing out the merits of others' opinions. David Keith has worked near the interface between climate science, energy technology, and public policy for twenty years. Working across the portfolio of applications and services provided by SEAS Computing to ensure that the users’ needs are the foremost concern.
