Technological fixes for climate change: Should we turn the planet into a laboratory?
Dr Jack Stilgoe , Senior Lecturer, Department of Science and Technology Studies, University College London
Abstract: Most sensible people agree that climate change is something that we need to deal with, but our attempts to do so have not achieved much so far. Some scientists have suggested another approach – finding a technological fix to cool the planet. Would such things work? How would we govern them? Would they make us give up on reducing greenhouse gas emissions? Is it OK to turn the world into a laboratory?
Dr Jack Stilgoe is a senior lecturer in the Department of Science and Technology Studies at University College London, currently on sabbatical at the University of Colorado. He has spent his professional life in the overlap between science policy research and science policy practice, at the think tank Demos, the Royal Society and at UCL, where he teaches courses on science policy and responsible science and innovation. His research focuses on the democratic governance of new science and technology. He has advised the European Commission and UK Research Councils on Responsible Research and Innovation. He co-edits the Political Science blog for the Guardian.

Over the past 15 years our research interests have focused on four main and related areas: 1. properties, chemistry, catalytic, and photo-catalytic behavior of neutral, inorganic, isolated clusters, MmM’nXpHq (M,M’ = metals, X = O, S, C); 2. initial release of stored chemical energy from isolated energetic molecules (e.g., RDX, HMX, CL -20, high N- content species, …); 3. small molecule, neutral clusters (e.g., (NH3)n, (H2O)n, (NH3BH3)n, (SO2)n, …) and their ion chemistry; and 4. structure, energetics, ion fragmentation reactions of “simple” bio-related molecules (e.g., amino acids, saccharides, neurotransmitters, and DNA bases). These studies have evolved from characterization of energy levels and intermolecular interactions, to ultrafast kinetics and dynamics of molecular cluster reactions, to the study of inhomogeneous catalytic and photo-catalytic cluster reactions. Clusters and molecules are identified through mass spectrometry, UV/Vis electronic spectroscopy, and most recently photo-electron spectroscopy (PES) employing visible, UV, VUV, extreme ultraviolet (EUV, soft x-ray) lasers. Decomposition reactions for the initial release of molecular stored chemical energy have been time resolved at less than 100 fs. In order to acquire, analyze, and interpret the experimental data obtained on these systems, we have had to develop an essential theoretical/calculational component for our program. This seminar reviews our initial synthesis and reaction studies through mass spectrometry of neutral catalytic and photo-catalytic inorganic clusters, small molecule cluster ion reactions, and for generation of new cluster species. These results serve as motivation for constructing a new PES apparatus employing visible, UV, VUV, and EUV for photo-detachment of anionic and neutral species in order to acquire spectroscopic data on the systems of interest. The importance of the new spectroscopic (PES) data for these systems is that they enable the evaluation of theoretical techniques in order that proper algorithms and approaches may be employed to generate results that are not presently experimentally accessible, such as cluster and molecular structure, reaction mechanisms, and general electronic state specific potential energy surfaces. We will discuss these issues and more as time and new developments and analyses in the laboratory permit.

The Colorado ACS Section is looking for members to participate on all committees. These committees help with various activities such as planning programming in CO, promoting science on the national level to government officials, or brainstorming and implementing ways to get younger chemists and others more involved. We invite you to select committees below that interest you. We appreciate each volunteer and their busy schedule—the opportunities to get involved can vary from one day to multiple days over the year depending on what you personally have time for. You will get to decide your commitment. Visit: http://goo.gl/forms/jxKlOkvSp4
