This report discusses the effect of human activities on global climate change. Human activities, particularly burning of fossil fuels, have increased atmospheric carbon dioxide (CO2) and other trace gases, including chlorofluorocarbons (CFCs), methane, and nitrous oxide.

The Nuclear Waste Policy Act of 1982 (NWPA) calls for disposal of spent nuclear fuel in a deep geologic repository that is unlikely to be disturbed for thousands of years. Low-level waste sites are a state responsibility under the Low-Level Radioactive Waste Policy Act of 1980. Pursuant to that act, 10 regional compacts for disposal of low level waste have been approved by Congress. Three commercial low-level waste sites are currently operating, in the states of South Carolina, Utah, and Washington.

Sub-Saharan Africa has been far more severely affected by AIDS than any other part of the world. The United Nations reports that 25.3 million adults and children are infected with the HIV virus in the region, which has about 10% of the world's population but more than 70% of the worldwide total of infected people. This report discusses this issue in detail, including the cause of the African AIDS epidemic, the social and economic consequences, response and treatment, and U.S. policy.

This report discusses issues regarding contemporary relations between India and the U.S. Continuing U.S. interest in South Asia focuses on ongoing tensions between India and Pakistan, a problem rooted in unfinished business from the 1947 Partition and competing claims to the Kashmir region. The United States also seeks to curtail the proliferation of nuclear weapons and ballistic missiles in South Asia. U.S. concerns about human rights issues related to regional dissidence and separatism in several Indian states also continue.

Proposals to replace all or part of the income tax, proposals for national health care, and a proposal to finance America’s war effort have sparked congressional interest in the possibility of a broad-based consumption tax as a new source of revenue. Avalue-added tax (VAT) or a national sales tax (NST) have been frequently discussed as possible new tax sources. Both the VAT and the NST are taxes on the consumption of goods and services and are conceptually similar. Yet, these taxes also have significant differences. This issue brief discusses some of the potential policy implications associated with these differences.

This is one report in the series of reports that discuss the campaign finance practices and related issues. Concerns over financing federal elections have become a seemingly perennial aspect of our political system, centered on the enduring issues of high campaign costs and reliance on interest groups for needed campaign funds. The report talks about the today’s paramount issues such as perceived loopholes in current law and the longstanding issues: overall costs, funding sources, and competition.

Two separate but closely related issues confront Congress each time the President introduces armed forces into a situation abroad that conceivably could lead to their involvement in hostilities. One issue concerns the division of war powers between the President and Congress, whether the use of armed forces falls within the purview of the congressional power to declare war and the War Powers Resolution. The other issue is whether Congress concurs in the wisdom of the action. This issue brief does not deal with the substantive merits of using armed forces in specific cases, but rather with the congressional authorization for the action and the application and effectiveness of the War Powers Resolution.

This is a clash between the principles of territorial integrity and self-determination that is occurring in the Caucasus, creating the longest inter-ethnic dispute in the former Soviet Union.

The report discusses the Armenian and Azerbaijani perspective, the role and views of others (Iran, Turkey, Russia), as well as the U.S. policy regarding the conflict.

For more than a century, the federal government has constructed water resource projects for a variety of purposes, including flood control, navigation, power generation, and irrigation. While most municipal and industrial water supplies have been built by non-federal entities, most of the large, federal water supply projects in the West, including Hoover and Grand Coulee dams, were constructed by the Bureau of Reclamation (Department of the Interior) to provide water for irrigation.

The United States recognized the independence of all the former Soviet republics by the end of 1991, including the South Caucasus states of Armenia, Azerbaijan, and Georgia. The United States has fostered these states' ties with the West in part to end the dependence of these states on Russia for trade, security, and other relations. The FREEDOM Support Act of 1992 provides authorization for assistance to the Eurasian states for humanitarian needs, democratization, and other purposes. In the aftermath of the September 11, 2001, terrorist attacks on the United States, the Administration appealed for a national security waiver of the prohibition on aid to Azerbaijan, in consideration of Azerbaijan's assistance to the international coalition to combat terrorism. Azerbaijani and Georgian troops participate in stabilization efforts in Afghanistan and Iraq, and Armenian personnel serve in Iraq.
