CLIMATE CHAOS

A long look back at human interactions with changing climate issues in the past.

Archaeologists Fagan and Durrani, the former of whom has written about climate and natural resources in several popular books, survey the “story of how our ancestors adapted to…myriad shifts, large and small,” as portions of the world alternately heated and cooled. One adaptation of long standing is simply to move, as Ancestral Puebloan people did when a centurylong drought settled over what is now the Southwestern U.S. Ecological refugees who are leaving present-day drought-stricken zones in places such as the Sahel are evidence of “the ancient survival strategy of mobility on a truly massive scale.” The massive drought that has settled over the present-day Southwest does not afford the same ability. As exploding population in the region, the authors write, has “placed major stresses on groundwater and other scarce water supplies as global warming intensifies.” Given that mass migration “is no longer a viable option in our time,” it’s up to modern planners to figure out a way to ensure the chances of our survival. While questioning our near-religious faith in the thought that technology can somehow save us, the authors allow that it will help, even as we continue to wreak catastrophic damage. Megadroughts in places such as the Southwest and India are not our only concern; the authors write of climate change–induced flooding and plagues, noting that the difference between present and past is that the natural alterations of old are now human-caused. What we do have going for us, the authors conclude in this accessible survey, is our ability to think problems through. “In planning adaptations to future climate change,” they write, “we need to maximize those enduring qualities that will sustain us as we plan decisive adaptations for the future.” That includes local leadership to address local effects.

Can we survive climate change? This learned book suggests that we can, but it won’t be easy.
