Edith's Checkerspot Butterfly has been disappearing from the lower elevations and southern limits of its range. 21.74 inches of rain fell in February, the most rain in a month since record keeping began. Global warming is likely to bring many changes to the nation. The United States as a whole is in a strong economic position to adapt to many of these changes, but adaptation is often expensive, not always possible or successful, and during transitions, ecosystems, communities, and individuals could suffer. Moreover, national impact summaries disguise local dislocations and disruptions to the ways we live, work and recreate.
Climate change adds a serious stress to our already threatened resources and treasured places.
Overall impact statements also mask significant opportunities. To minimize the negative changes and make the most of the positive changes we need to take a close look at how climate change will affect each region. California's remarkable quality of life and economic strength is built on a rich and diverse base of natural capital. From a vast array of ecosystems and species to bountiful resources and a unique geography, California is endowed with natural assets that underpin its success and wealth. National treasures like Yosemite and the redwoods share the land with major metropolitan areas and some of the most productive agriculture in the world.
