A comprehensive test ban treaty, or CTBT, is the oldest item on the nuclear arms control agenda. These treaties currently limit testing to underground only, with a maximum force equal to 150,000 tons of TNT. Since 1997, the United States has held 22 "subcritical experiments" at the Nevada Test Site, asserting that these experiments do not violate the CTBT because they cannot produce a self-sustaining chain reaction. The Senate rejected the CTBT on October 13, 1999, and the current Administration under President George W. Bush has indicated that it will continue to oppose the CTBT, will continue to adhere to the test moratorium, is considering modifying existing warheads for use against hard and deeply-buried targets, has not ruled out resumed testing, and has no plans to test.

This report discusses policy options for Congress regarding gas prices. The high price of gasoline was an important consideration during the debate on major energy legislation, which ended August 8 as the President signed the Energy Policy Act of 2005, H.R. 6 (P.L. 109-58). However, prices continued to surge, spiking at the end of August when Hurricane Katrina shut down refining operations in the Gulf of Mexico. The continuing crisis renewed attention to some issues that were dropped or compromised in the debate over P.L. 109-58. A large number of factors combined to put pressure on gasoline prices, including increased world demand for crude oil and U.S. refinery capacity inadequate to supply gasoline to a recovering national economy. The war and continued violence in Iraq added uncertainty and a threat of supply disruption that added pressure particularly to the commodity futures markets.

This report briefly reviews the status of climate science, international negotiations, and congressional activity focused specifically on climate change.

U.S.-China economic ties have expanded substantially over the past several years. China is now the third largest U.S. trading partner, its second largest source of imports, and its fourth largest export market. However, U.S.-China commercial ties have been strained by a number of issues, including a surging U.S. trade deficit with China, China's refusal to float its currency, and failure to fully comply with its World Trade Organization (WTO) commitments, especially its failure to provide protection for U.S. intellectual property rights (IPR). This report explores these issues in detail, especially concerning the lack of protection for U.S. IPR.
