What's important here, and remains important, scientists say, is how the patterns of atmospheric and climatic change reveal the most about the involvement of greenhouse gases, not simply the change in global temperature.

Human development including the disruption of normal coastal geomorphic forces by coastal infrastructure assure that any change in global temperature and consequent sea level, will be a disaster to these environments.

While the state of the climate clearly involves much more than just global temperature, changes in global temperatures do indicate the scale of different climatic events, both natural and man - made.
