| | Testimony by Thomas R. Karl, Co-chair, NOAA National Climatic Data Center and other witnesses before hearing of the US Senate Commerce, Science, and Transportation Committee on climate variability and change, July 18, 2000 |
 | | This synthesis obviously needed to build on the work that had begun to emerge from the subsequent regional and national studies, but also to draw on the existing scientific literature and analyses done with the most up-to-date ecological and hydrological models and data that could be obtained. |
 | | Climate change and the resulting rise in sea level are likely to exacerbate threats to buildings, roads, power lines, and other infrastructure in climatically sensitive places, such as low-lying coastlines and the permafrost regions of Alaska. |
 | | In addition to these kind of "bottom-up" efforts, it was decided that it was also necessary to create a national-level synthesis of what is known about the potential for climate impacts for the US as a whole, addressing the issues identified in the regional workshops and national studies. |
