Over the next century, sea level rise in the Los Angeles region is expected to match global projections with an increase of 0.1 - 0.6 m (5 - 24 inches) from 2000 to 2050 and 0.4 - 1.7 m (17 - 66 inches) from 2000 to 2100. Tides, wave-driven runup, and storm surge sometimes cause coastal flooding in Southern California, especially when big wave storms occur at or near peak high tides.

Springs are keystone ecosystems in the Sky Island Region, exert disproportionate influence on surrounding landscapes, and are known to be biodiversity hotspots. Although they are abundant in this arid region, they are poorly documented and little studied. They also suffer from extensive human modification and are among the most threatened ecosystems.
We present a landscape-scale climate change adaptation plan that characterizes climate vulnerability and provides a foundation for adaptation action on the North Rim Ranches, a 3,360-km2 (830,000-acre) landscape of significant ecological and cultural importance on the North Rim of the Grand Canyon.
Climate change may affect the ability to achieve on-the-ground project goals and objectives. The following case study demonstrates how climate change vulnerability and adaptation information can be integrated into existing and future regional grazing management projects to increase overall project resilience.
