Secrets of the Ice - An Antarctic Expedition

The International Trans-Antarctic Scientific Expedition (ITASE) program was created to study ice over the major topographic and climatic regions of Antarctica. Over the next four years, scientists from 15 countries will be traversing Antarctica, collecting ice cores and gathering data that will describe climate and environmental change over the past 200 years. The ice core records gathered will provide detailed historical descriptions of climate changethat will be extremely valuable for comparison against records collected at weather stations around the world.

Paleoclimatology Program

NOAA's Paleoclimatology Program is working with scientists from around the world to study past climate in hopes of achieving a better understanding of the Earth's present and future climate. This site was developed to highlight the importance of paleoclimate research; as well as to show how paleoclimate research relates to global warming and other important issues of climate variability and change.

American Geophysical Union

Read the position statement of the American Geophysical Union on Climate Change and Greenhouse Gases, which was adopted by the Council in December 1998.

EPA Global Warming

The EPA Global Warming Site is provided as a public service by the U.S. Environmental Protection Agency. EPA's climate change programs and activities are an integral part of the Agency's mission and purpose. With the Global Warming Site, the EPA strives to present accurate information on the very broad issue of climate change and global warming in a way that is accessible and meaningful to all parts of society – communities, individuals, business, public officials and governments.

NOAA Climate Change Research

The Office of Global Programs (OGP) leads the NOAA Climate and Global Change Program. NOAA has the primary responsibility within the federal government to provide routine climate forecasts and products to the nation. NOAA's Climate and Global Change Program is an integral part of the interagency U.S. Global Change Research Program and works to address an important aspect of global change--understanding the global climate system.

U.S. Global Change Research Program

The U.S. Global Change Research Program (USGCRP), working with research institutions in the U.S. and beyond our borders, provides the foundation for increasing the skill of predictions of seasonal-to-interannual climate fluctuations (which can bring excessively wet and dry periods) and long-term climate change. The USGCRP also sponsors research to understand the vulnerabilities to changes in important environmental factors, including changes in climate, ultraviolet (UV) radiation at the Earth's surface, and land cover.
The USGCRP was created as a Presidential Initiative in 1989 and formalized in 1990 by the Global Change Research Act of 1990.

NASA Goddard Institute for Space Studies

GISS is a division of Goddard Space Flight Center's Earth Sciences Directorate. It was established in May 1961 by Dr. Robert Jastrow to do basic research in space and Earth sciences in support of Goddard programs. GISS works cooperatively with area universities and research organizations.

The GMDC's Learning Center

The Learning Center is the place to come for all sorts of data and information about global environmental change. The Learning Center is part of NASA's Global Change Master Directory which has links to a vast amount of information on changes in the hydrosphere, atmosphere and biosphere.
