It does not do a complete analysis of the costs, benefits, or feasibility of these options however, which is a necessary next step for developing policies to address these issues. Differing regional impacts. Temperature increases will vary somewhat from one region to the next. Heavy and extreme precipitation events are likely to become more frequent, yet some regions will get drier. The potential impacts of climate change will also vary widely across the nation.
Ecosystems are highly vulnerable to the projected rate and magnitude of climate change.
A few, such as alpine meadows in the Rocky Mountains and some barrier islands, are likely to disappear entirely, while others, such as forests of the Southeast, are likely to experience major species shifts or break up. The goods and services lost through the disappearance or fragmentation of certain ecosystems are likely to be costly or impossible to replace. Widespread water concerns. Water is an issue in every region, but the nature of the vulnerabilities varies, with different nuances in each. Drought is an important concern in every region.
