If your answer is yes and yes then it may be necessary to embark on some form of geoengineering the deliberate introduction of most likely sulfur aerosols into the stratosphere to reflect light into space and counter the greenhouse effectMorton is a professional science writer and he has a keen grasp of good analogies to describe the flows of energy through the upper surface of Earth and the scientific discoveries that lead to theories of geoengineering Major volcanic eruptions in the late 90s offered a case to test the assumptions of primitive climate models against the introduction of bulk surfer aerosols with sudden cooling and associated hemispheric changes in the weather Of course climate models are relatively crude and there's still much that we don't know about the effects on weather which is what people notice and care about rather than the climate The ease of geoengineering is stark Perhaps 10 billion to set up a fleet of stratospheric tankers and a 2 billion annually to maintain the program Big science yes but costs on the order of a few large nuclear plantsThe problem with geoengineering is it's Promethean potential It's not that the actual practice is wholly new Climate change is just one natural cycle now substantially influence to completely dominated by human activity from the Haber Bosch process and nitrogen fertilizer to phosphorus fertilizer to the narrowly averted disaster of CFCs and the ozone layers To take a major Earth system deliberately in hand and say this is what we want it to be is a new level of planetary ambition Geonegineering induced cooling will have some losers and the politics of those harms are not well mapped outThis is where Morton falls short He imagines a scenarios where a Concord of minor states threatened by climate change enact geoengineering but it seems likely that a major power or even a billionaire operating under a flag of convenience will get there first The internal politics of geoengineering its scientific debates and relationship to mainstream atmospheric physics and ecological activism are sorely under reported Still I can't think of a better book on the topic

Oliver Morton ¹ How Geoengineering Could Change the World ebook

The risks of global warming are pressing and potentially vast The difficulty of doing without fossil fuels is daunting possibly even insurmountable So there is an urgent need to rethink our responses to the crisis To meet that need a small but increasingly influential group of scientists is exploring proposals for planned human intervention in the climate system a stratospheric veil against the sun the cultivation of photosynthetic plankton fleets of unmanned ships seeding the clouds These are the technologies of geoengineerin and as O 56th book for 2016Oliver Morton has been following the geoengineering movement for years In this book he offers a detailed assessment of where things were are and perhaps will be I came into the book as a huge skeptic of either the utility or feasibility of geoengineering the planet to mitigate the effects of global warming By the end of the book I was convinced the geoengineering would happen and perhaps even that this was a good thing at the least the best course in a very bad situation For anyone interested in global warming and all things Anthropocene this is a necessary read

doc Æ How Geoengineering Could Change the World ¹ Oliver Morton

The Planet Remade How Geoengineering Could Change the WorldLiver Morton argues in this visionary book it would be as irresponsible to ignore them as it would be foolish to see them as a simple solution to the problemThe Planet Remade explores the history politics and cutting edge science of geoengineering Morton weighs both the promise and perils of these controversial strategies and puts them in the broadest possible context The past century's changes to the planet to the clouds and the soils to the winds and the seas to the great cycles of nitrogen and carbon have been far profound than most Morton begins his synopsis of the possibilities of geoengineering by establishing the necessity of it He begins with two uestions do you think climate change is bad enough to do something about it? do you think reducing emissions enough is very hard to do maybe impossible? He answers yes to both uestions and says that most of today's politicans and environmentalists today answer no to one of these uestions and yes to the other depending on their political leanings But he says if we need to do something about climate change and emissions reductions are not enough we have to look at geoengineeringThe primary action he examines is injecting aerosols into the stratosphere That would in effect shade us a bit so that we can have high carbon dioxide levels but not so much heating He's definitely a cheerleader for this but he's aware of the objections that have been or will be raised as this possibility works its way into the mainstream discussion about climate changeHe includes a wide ranging historical analysis of how humans have changed the climate both intentionally or considered doing it intentionally and unintentionally This discussion was wide and detailed enough that he lost my interest a couple times but I'll credit him with being thorough And he does make his point We are now and have been for at least a few decades if not centuries influential enough to change climate on a geologically noticeable scaleHe doesn't side step the fear that intentionally changing the climate excites in most people He addresses objections one by one in a or less fair manner He makes other forms of geoengineering such as pulling CO2 out of the air and storing it or seeding the ocean with nutrients to seuester CO2 that way seem interesting but insufficient In the latter case it may even hurt the cause And one of the biggest objections is that people may think that spreading sulfates as a shield would mean that we don't then need to reduce emissions that's absolutely false we still would and he clearly states that over and over So on the whole I thought he presented a responsible picture of the possibilities and risks of trying to construct our own climateIn the end I'm not as enthusiastic about geoengineering as Morton is but I'm thankful for the well researched well written book and I walk away informed and open minded than when I started That's a good outcome for any book on the topic I would think I got a free copy of this from Net Galley
