You are one of seven billion people on Earth. Whatever you or I do personally--eat tofu in a Hummer or hamburgers in a Prius--the planet doesn't notice. In our confrontation with climate change, species preservation, and a planet going off the cliff, it is what several billion people do that makes a difference. The solution? It isn't science, politics, or activism. It's smarter economics. The hope of mankind, and indeed of every living thing on the planet, is now in the hands of the dismal science. Fortunately, we've been there before. Economists helped crack the acid rain problem in the 1990's (admittedly with a strong assist from a phalanx of lawyers and activists). Economists have helped get lead out of our gas, and they can explain why lobsters haven't disappeared off the coast of New England but tuna is on the verge of extinction. More disquietingly, they can take the lessons of the financial crisis and model with greater accuracy than anyone else the likelihood of environmental catastrophe, and they can help save us from global warming, if only we let them.

How Smart Economics Can Save the World

But Will the Planet Notice?

The Business of Sustainability is a core resource for policy makers, members of the development community, entrepreneurs, and corporate executives, as well as business and economics students and their professors. It contains rich analysis of how sustainability is being factored into industries across the globe, with enlightening case studies of businesses serving as agents of change. Contributing authors provide a groundbreaking body of research-based knowledge. They explain that the concept of sustainability is being re-framed to be positive about business instead of being tied to the old notion of a trade-off between business and society (that is, if business wins, society and the environment must lose), and they explore how economic development can contribute to building our common future.

Stabilizing the world’s climates means cutting carbon dioxide pollution. There’s no way around it. But what if that’s not enough? What if it’s too difficult to accomplish in the time allotted or, worse, what if it’s so late in the game that even cutting carbon emissions to zero, tomorrow, wouldn’t do? Enter solar geoengineering. The principle is simple: attempt to cool Earth by reflecting more sunlight back into space. The primary mechanism, shooting particles into the upper atmosphere, implies more pollution, not less. If that doesn’t sound scary, it should. There are lots of risks, unknowns, and unknowables. In Geoengineering: The Gamble, climate economist Gernot Wagner provides a balanced take on the possible benefits and all-too-real risks, especially the so-called “moral hazard” that researching or even just discussing (solar) geoengineering would undermine the push to cut carbon emissions in the first place. Despite those risks, he argues, solar geoengineering may only be a matter of time. Not if, but when. As the founding executive director of Harvard’s Solar Geoengineering Research Program, Wagner explores scenarios of a geoengineered future, offering an inside-view of the research already under way and the actions the world must take to guide it in a productive direction.

The Gamble

Geoengineering

How knowing the extreme risks of climate change can help us prepare for an uncertain future If you had a 10 percent chance of having a fatal car accident, you'd take necessary precautions. If your finances had a 10 percent chance of suffering a severe loss, you'd reevaluate your assets. So if we know the world is warming and there's a 10 percent chance this might eventually lead to a catastrophe beyond anything we could imagine, why aren't we doing more about climate change right now? We insure our lives against an uncertain future—why not our planet? In Climate Shock, Gernot Wagner and Martin Weitzman explore in lively, clear terms the likely repercussions of a hotter planet, drawing on and expanding from work previously unavailable to general audiences. They show that the longer we wait to act, the more likely an extreme event will happen. A city might go underwater. A rogue nation might shoot particles into the Earth's atmosphere, geoengineering cooler temperatures. Zeroing in on the unknown extreme risks that may yet dwarf all else, the authors look at how economic forces that make sensible climate policies difficult to enact, make radical would-be fixes like geoengineering all the more probable. What we know about climate change is alarming enough. What we don't know about the extreme risks could be far more dangerous. Wagner and Weitzman help readers understand that we need to think about climate change in the same way that we think about insurance—as a risk management problem, only here on a global scale. With a new preface addressing recent developments Wagner and Weitzman demonstrate that climate change can and should be dealt with—and what could happen if we don't do so—tackling the defining environmental and public policy issue of our time.

The Economic Consequences of a Hotter Planet

Climate Shock

Wir haben die Wahl. In den Entscheidungen, wie wir wohnen, essen und reisen, wie wir unseren Alltag gestalten und welche Politik wir wählen, liegt der Schlüssel für eine zukunftstaugliche Welt. Dabei schließen sich wirtschaftliche Prinzipien und Umweltschutz aus? Klimafreundlich zu leben bedeutet Verzicht? Keineswegs! Gernot Wagner liefert anschauliche Beispiele aus seinem Leben und spricht über Fragen, die sich ihm und vielen von uns stellen. Der überraschende Befund: Ausgerechnet in den oft als naturfeindlich verschrienen Städten steckt die Lösung. Zwischen modernster Technologie und Fahrrad, Kreativität und Bodenständigkeit, Effizienz und Resilienz können wir ein neues Klimakapitel aufschlagen. Um gute Entscheidungen zu ermöglichen, braucht es aber mehr. Der renommierte Klimaökonom fordert ein Umdenken im großen Stil, um politische Weichen neu zu stellen, Anreize zu schaffen und Wirtschaftsströme umzulenken. Wissenschaftlich fundiert und leichtfüßig weist dieses Buch den Weg vom Klimaschmutz zu Klimaschutz.

Warum wir nur mit einem urbanen Leben die Erde retten
