Climate change is a problem so enormous and complex—with threats so frightening in their implications—that many of us fend off confusion and hopelessness by simply turning away. Meanwhile, with delayed action, missed targets, and increasingly dire reports at the international level, a notion that the crisis is intractable continues to spread. And the proposed solutions can be just as daunting. They often involve jargon about gigatons of carbon and kilowatt-hours of electricity. In a deeply polarized political environment, any sense of the common purpose required to make these work seems to dissolve into denial or paralysis. With all this fear and conflict, the question must be asked: How do we find the tools and the hope we need to tackle such a wickedly difficult issue? In Climate Hope, journalist David Geselbracht blends in-depth research, expert interviews, and on-the-ground reporting in multiple countries, revealing remarkable efforts to identify the causes and impacts of climate change—and devise crucial ways to address them. The scale of the challenge is clear in the range of fields he covers, from glaciology and climate science to law and diplomacy. But in drawing these approaches together, he shares stories of hope, awe, and wonder that encourage us to confront this long-term, world-warping phenomenon with a renewed sense of purpose and possibility.Show book

Opossums in the wild don't make it to the age of three; our pet cats can live for a decade and a half; cicadas live for seventeen years. Whales, however, can live for two centuries and tubeworms for several millennia. Meanwhile, human life expectancy tops out around the mid-eighties, with some outliers living past 100 or even 110. Is there anything humans can learn from the exceptional longevity of some animals in the wild? In Methusaleh's Zoo, Steven Austad tells the stories of some extraordinary animals, considering why, for example, animal species that fly live longer than earthbound species and why animals found in the ocean live longest of all. Austad—the leading authority on longevity in animals—argues that the best way we will learn from these long-lived animals is by studying them in the wild. Accordingly, he proceeds habitat by habitat, examining animals that spend most of their lives in the air, comparing insects, birds, and bats; animals that live on, and under, the ground—from mole rats to elephants; and animals that live in the sea. Humans have dramatically increased their lifespan with only a limited increase in healthspan; we're more and more prone to diseases as we grow older. By contrast, these species have successfully avoided both environmental hazards and the depredations of aging. Can we be more like them?Show book

Unmasked is the story of what happened in Okoboji, a small Iowan tourist town, when a collective turn from the coronavirus to the economy occurred in the COVID summer of 2020. State political failures, local negotiations among political and public health leaders, and community (dis)belief about the virus resulted in Okoboji being declared a hotspot just before the Independence Day weekend, when an influx of half a million people visit the town. The story is both personal and political. Author Emily Mendenhall, an anthropologist at Georgetown University, grew up in Okoboji, and her family still lives there. As the events unfolded, Mendenhall was in Okoboji, where she spoke formally with over 100 people and observed a community that rejected public health guidance, revealing deep-seated mistrust in outsiders and strong commitments to local thinking. Unmasked is a fascinating and heartbreaking account of where people put their trust, and how isolationist popular beliefs can be in America's small communities.Show book
