A Case for Climate EngineeringEr atmosphere has emerged in recent years as an extremely controversial technology And for good reason it carries unknown risks and it may undermine commitments to conserving energy Some critics also view it as an immoral human breach. In a recent interview with David Keith the author of “The Case for Climate Engineering” humorist Stephen Colbert jokingly referred to climate engineering as the “All Chocolate Dinner” a proposal that would allow humans to deal with global warming while spraying sulfuric acid into the high atmosphere Beneath the humor Colbert was focusing on the essential problem of climate engineering the countless moral issues and human passions that the topic raisesTo his credit David Keith does not duck or minimize these issues in his short book 174 pages Keith admits that a future Planet Earth in which climate engineering counteracts global warming is NOT the same as a world without global warming Not only will rainfall patterns be different from our current world but the World Ocean will eventually die from acidification because climate engineering would address only the temperature rise of carbon dioxide emissions NOT the chemical fallout of oceanic carbon absorption There is also a thing called “risk compensation” This is a concept of economic psychology that climate engineering would carry the risk of supplying the human race with a false sense of security on the topic of global warming We imagine future generations of humans blandly dismissing global warming as a threat because an organized program of spreading sulfuric acid micro droplets in the high atmosphere has reduced the temperature gain Keith admits that this could become a reality and admits that such tinkering with the high atmosphere's reflective ualities would in fact be only addressing the symptoms of global warming not the disease itself and could have some unpleasant unintended conseuence In fact the amount of sulfuric acid injected into the sky would have to increase every year in order to counteract a constantly climbing amount of CO2 in the sky Start out with spending a billion bucks per year but the amount of money would climb In order to resolve the “risk compensation” issue Keith proposes only putting enough sulfuric into the sky to address HALF the temperature gain of global warming This he explains would be a measure to maintain a sense of urgency to prevent future humans from ignoring the actual pathway to success in climate balancing that of reducing carbon emissions to a low enough amount And we should start with some trial runs taking careful observations of results before jumping in whole hog writes Keith Why then even raise the issue of climate engineering if it is admittedly fraught with moral issues and “unknown unknowns” as Donald Rumsfeld once said on a different topic Well Desperation is the main reason Keith points out the the human race has talked about global warming uite a bit in recent decades but been pretty unsuccessful in attempting to reduce CO2 emissions Sure there are baby steps in the renewable energy industry but we are decades away from replacing fossil fuels notes Keith In this assertion he is uite correct The Kyoto protocol is essentially dead and it has not been replaced with anything meaningful We live under a global warming framework that can be described as “every man for himself” As an environmentalist I approached this book with a very doubtful attitude In the end Keith's admissions of vulnerability may not have turned me into a geo engineering fan but I did decide to give him 4 stars for writing a fairly honest basic primer on this complex and scary topic One caveat if you really do not know anything about global warming this is not the book for you to start out with Some of the science in the middle of the book may be over your head But I would suggest that every voter should try to gain an understanding of this topic So if you know nothing about GW read up on it at the climate central website then try this book to get up to speed on the topic of climate engineering You are likely to hear about this topic in future years since as Keith noted we are not currently devoting adeuate resources to de carbonize the world economy and the longer we fail the better climate engineering will start to look Note climate denialists will hate this book because Keith has no doubt whatsoever that global warming is a serious threat to the human future Some environmentalists will like it while others will not

A leading scientist argues that we must consider deploying climate engineering technology to slow the pace of global warming Climate engineering which could slow the pace of global warming by injecting reflective particles into the upp. In this very short book David Keith recommends that a large scale research program be started The program would investigate whether climate engineering would be practical and assess its practicality and side effectsBy climate engineering Keith means spraying the upper stratosphere with sulfate aerosol in order to decrease solar insolation The intention is to decrease the rate of global warming Keith makes it uite clear that he would not want to replace a program of cutting down on emissions of greenhouse gases particularly carbon dioxide His intention is to supplement a reduction in greenhouse gases in order to alleviate the worst effects of global warmingKeith goes through a number of arguments for and against such a program of climate engineering He factors in the costs the side effects and the politics of such a program He sees the most insidious side effect as a reduction in the political will to reduce greenhouse gas productionKeith lays out the science and describes the political problems that are involved He makes it clear that the decision to go ahead with such a program is not one to be made by scientists The decision is a political one to be made by the general public in assessing the benefits and the risksThis is an excellent book for understanding this intriguing approach toward alleviating but not reversing global warming My only reservation in recommending this book is this David Keith hire a good editor The book is filled with so many typos and grammatical errors; they distracted my attention from the interesting content

A rather easy to read introduction to the concept of solar geo engineering which has been vaguely heard before This allows us to have a grasp of what has happened and the pros and cons of this concept to reduce the climate change in addition to but not abandoning the need of CO2 emission cut
