NASA scientist publishes new book: 'Coming Climate Crisis? Consider the Past, Beware the Big Fix'
Date:4/19/2010

In the midst of seemingly unending questions about climate change, a new book by Claire L. Parkinson, a world-renowned climate scientist at NASA's Goddard Space Flight Center in Greenbelt, Md., can provide some answers.

The book, entitled "Coming Climate Crisis? Consider the Past, Beware the Big Fix," will be published this week by Rowman & Littlefield.

Parkinson explains why global warming is such a big deal, summarizes 4.6 billion years of climate change on Earth, including periods when Earth was much warmer than now (and others when it was much cooler), and addresses and explains various 'geo-engineering' schemes being proposed to intentionally modify future climate.

The book includes a brief history of human impacts and predictions of what might occur in the near future. The bleak nature of some of the predictions, along with the knowledge from climate history that the Earth system is capable of abrupt climate change, make it understandable why geoengineering is being considered. However, Parkinson also explains many limitations of our computer models and potential dangers of unintended consequences, concluding that massive geoengineering "could backfire to become a greater disaster than the one we are trying to correct." She describes some of the alternatives to geoengineering that could more safely reduce the unwanted changes.

In this new book, Parkinson attempts to bring balance and perspective and clarify some of the most important and contentious points in the ongoing climate debate. While clearly enthusiastic about what we have learned through science about the history of the Earth and the intricacies of the Earth system, she also cautions against assuming that our understandings are more complete than they really are.

"This book interweaves discussion of relevant aspects of Earth history, science, the history of science, and human nature," Parkinson said. "We cannot adequately understand the present or r
