Adaptation measures, on the other hand, aim to improve an individual or institution's ability to cope with or avoid harmful impacts of climate change, and to take advantage of potential beneficial ones. The American Clean Energy and Security Act of 2009 ( H.R. 2454 ) passed the House on June 26, 2009. The Senate Environment and Public Works (EPW) Committee approved the Clean Energy, Jobs, and Power Act ( S. 1733 ) on November 5, 2009. Both bills also include adaptation provisions that (1) seek to better assess the impacts of climate change and variability that are occurring now and in the future; and (2) support adaptation activities related to climate change, both domestically and internationally. 2454 and S. 1733 . A side-by-side table in an Appendix to the report compares relevant provisions related to climate change adaptation in both bills. The provisions are grouped into the following headings:
International Climate Change Adaptation Domestic Climate Change Adaptation (including the National Climate Change Adaptation Program and the National Climate Services Program) State and Tribal Programs Public Health Natural Resources Adaptation Other Climate Change Adaptation Programs, including Water Resources (in S. 1733 only)

		Importance of Adaptation

Climate-related changes have been observed in the United States and globally. 2454 (as Passed by the House)

This report summarizes and compares the adaptation provisions in S. 1733 , as reported by the Senate Environment and Public Works (EPW) Committee on November 5, 2009, and H.R. Overall, while the two bills would authorize similar adaptation programs, they differ somewhat in scope and emphasis, and they also differ in the distribution of emission allowance allocations, which in effect provide monetary resources for specified programs and activities. S. 1733 contains five additional provisions (not contained in the House bill) that deal with: 
drinking water utilities; water system mitigation and adaptation partnerships; flood control, protection, prevention, and response; wildfire; and coastal Great Lakes state adaptation. Neither the Senate-reported bill ( S. 1733 ) nor the House-passed bill ( H.R. 2454 ) contains a process at the federal level for developing and implementing a national strategic plan to address the full range of sectors expected to be affected by climate change. Neither bill includes explicit provisions that address adaptation in major sectors such as transportation and energy infrastructure, or agriculture, although these activities are allowable under state programs for climate adaptation that are provided for in both bills. One significant difference between the two pieces of legislation is the distribution of allowances and proceeds from auction allocations and the subsequent availability of the amounts credited to certain funds. In contrast, the analogous adaptation provisions in the House bill provide that the amounts in the funds would become available only by subsequent appropriations. The provision of funding "without further appropriation" might be controversial. In H.R. Both H.R. 2454 . 2454 . S. 1733 and H.R.
This report summarizes and compares climate change adaptation-related provisions in the American Clean Energy and Security Act of 2009 (H.R. 2454) and the Clean Energy, Jobs, and Power Act (S. 1733). H.R. 2454 was introduced by Representatives Waxman and Markey and passed the House on June 26, 2009. S. 1733 was introduced to the Senate by Senators Boxer and Kerry and, after subsequent revisions made in the form of a manager's substitution amendment, was reported out of the Senate Environment and Public Works Committee on November 5, 2009.
Adaptation measures aim to improve an individual's or institution's ability to cope with or avoid harmful impacts of climate change, and to take advantage of potential beneficial ones. Both H.R. 2454 and S. 1733 include adaptation provisions that (1) seek to better assess the impacts of climate change and variability that are occurring now and in the future; and (2) support adaptation activities related to climate change, both domestically and internationally.
Overall, while the two bills would authorize similar adaptation programs, they differ somewhat in scope and emphasis, and they also differ in the distribution of emission allowance allocations over time. Both bills contain provisions that address international climate change adaptation; domestic climate change adaptation programs, including the U.S. Global Change Research Program (USGCRP), the National Climate Service, and state and tribal programs; public health; and natural resources adaptation. S. 1733 includes five additional provisions not provided for in the House bill that deal with drinking water utilities; water system mitigation and adaptation partnerships; flood control, protection, prevention, and response; wildfire; and coastal Great Lakes states' adaptation.
Neither the Senate-reported bill (S. 1733) nor the House-passed bill (H.R. 2454) contains a process at the federal level for developing and implementing a national strategic plan to address the full range of sectors expected to be affected by climate change. Neither bill includes provisions that explicitly address adaptation in major sectors such as transportation and energy infrastructure, or agriculture.
Another difference between S. 1733 and H.R. 2454 is the distribution of allowance allocations over time, and the subsequent availability of the amounts credited to certain funds. The relative distribution of allowances to adaptation-related activities is slightly higher in the House bill than in the Senate bill, and the difference increases over time, but the actual amounts of revenue generated would be contingent on the number and price of emission allowances. The Senate bill provides that funds for many adaptation-related provisions, such as for natural resources and public health, are made available "without further appropriations." In contrast, the analogous provisions in the House bill provide that the funds would become available only by subsequent appropriations.
A side-by-side table is included in an appendix to the report that compares adaptation-related provisions in H.R. 2454 and S. 1733.
