A nicely crafted NASA video on Earth as the water planet, highlighting the value of ocean-observing satellites and the role they play in understanding the global effects of climate change.

This in-depth interactive slideshow about how climate models work is embedded with a lot of background information. It also describes some of the projected climate change impacts to key sectors such as water, ecosystems, food, coasts, health. (scroll down page for interactive)

This short video from NASA discusses the role that salinity plays in Earth's climate and ocean circulation, focusing on the observations of the Aquarius satellite.

Informing Effective Decisions and Actions

Demand for information to support climate-related decisions has grown as people, organizations, and governments have moved ahead with plans to reduce greenhouse gas emissions and to adapt to the impacts of climate change. However, the nation lacks comprehensive, robust, and credible information systems to inform climate choices and evaluate their effectiveness. This report calls for a coordinated system of climate services to meet national needs for climate information pertaining to response options.

Global Climate Change Impacts in the United States (2009)

Climate changes are underway in the United States and are projected to grow. Consequently, crops and livestock production will be increasingly challenged and threats to human health will increase. These are two key findings presented in this 2009 assessment report by the U.S. Global Change Research Program. The report gives an overview of climate-related issues and impacts for seven geographical regions and seven sectors of society.

Climate Models: An Assessment of Strengths and Limitations

Scientists use mathematical models of Earth's climate, run on the most powerful computers available, to examine hypotheses about past and present-day climates. This report describes the models and their ability to simulate climate.
