摘要:

In a recent Congressional hearing, members of the House Science, Space, and Technology Committee criticized the United States for failing to take action to reduce emissions of carbon dioxide, despite scientific evidence that the greenhouse gas contributes to global warming. The Committee met July 17 to review technologies and strategies for addressing global warming.Following close on the heels of a pronouncement by British environment secretary Michael Heseltine, reported in the July 14 issue of theWashington Post,that Britain will no longer automatically side with the United States on the global warming issue, committee chairman George E. Brown, Jr. (D‐Calif.) said that “while many industrialized nations have adopted specific targets and timetables for curbing carbon dioxide emissions, the United States has resisted such an approach, which has resulted in a degree of isolation between our government and other major industrialized natio

摘要:

The $21.98 billion energy and water appropriations bill (HR 2427) was passed by the full Senate on July 10, representing an increase of about $1 billion over FY 1991 funding. With a 96‐3 vote, HR 2427 was one of the first of 13 spending bills to be approved by the Senate. (See “DOE Funding Up in FY 1991,”Eos,July 16.)The Senate appropriated $509 million to begin construction of the controversial Superconducting Super Collider (SSC) in Waxahachie, Texas. Earlier this year, the House voted $434 million for the project, which was $100 million less than requested by the administr

摘要:

The U.S. Arctic System Science Program of the National Science Foundation has been created “to document and understand the processes of the Arctic system that interact with the total Earth system” (NSF, ARCSS 1990). ARCSS research has three components: Land/Atmosphere/Ice Interactions, Ocean/Atmosphere/Ice Interactions, and Paleoenvironmental Studies, made up of the Greenland Ice Sheet Program and Paleoclimates of Arctic Lakes and Estuaries. PALE forms a link between the first two components as it seeks to document and understand changes in both terrestrial and nearshore marine environments.The need to integrate the community of Arctic paleoclimate researchers was perceived in the middle 1980s and this resulted in a focus on lake and nearshore sediment cores as a basis for proxy records of environmental change across the Arctic. Several workshops, held at the University of Colorado between 1987 and 1990 resulted in a proposal to the National Science Foundation Division of Polar Programs to establish a Steering Committee that would outline a science plan and coordinate national efforts toward these go

摘要:

An international effort to establish relational data bases for various classes of paleomagnetic and rock magnetic data is being coordinated by International Association of Geomagnetism and Aeronomy (IAGA) Working Groups I‐5 (Paleomagnetism) and I‐6 (Rock Magnetism). This article traces developments so far.It has become virtually impossible for any individual to keep track of, or access, the wealth of paleomagnetic and rock‐magnetic information that is available. Working Groups I‐5 and I‐6 of the IAGA have responded by seeking to establish data bases for various types of paleomagn

摘要:

Radio listeners across the country will soon get a daily introduction to the Earth and space sciences when a new syndicated radio program, “Earth and Sky,” debuts this fall. Produced by Deborah Byrd and Joel Block of Austin, Texas, the creative team behind the long‐running “Star Date” radio program, “Earth and Sky” premieres on September 30. The program is being produced in association with the American Geophysical Union.“‘Earth and Sky’ is a new vehicle for the dissemination of accurate and up‐to‐date information on Earth and space sciences,” says AGU Executive Director Fred Spilhaus. “It has tremendous potential to advance one of AGU's fundamental missions: to make the results of scientific resear
