In May and June each year, speculation about the coming of the monsoon fills newspapers and conversations across India. Everyone is concerned about if, when, and how much rain will arrive. But none have more at stake than India’s over 100 million farming households.

The total amount of water on Earth isn’t increasing, but the volume of liquid that fills the ocean is growing as ice and snow on land melt. The water is also getting warmer, which makes it expand. 

In this activity, students act as water molecules and travel through parts of the water cycle (ocean, atmosphere, clouds, glaciers, snow, rivers, lakes, ground, aquifer), noting on a hydrological cycle diagram the pathway traveled.

Climate Change 2013: The Physical Science Basis

On September 27, 2013, Working Group I of the Intergovernmental Panel on Climate Change (IPCC) presented its report to member governments for approval and acceptance. The report is the first of four that will make up the IPCC's 5th Assessment.

Climate Sensitivity of the Nation's Estuaries

The United States' 28 National Estuarine Research Reserves (NERR) are experiencing negative effects of human and climate-related stressors, according to a new report from NOAA's National Ocean Service. This is the first national-scale climate sensitivity analysis of estuaries to help coastal managers protect the health of estuaries.

Coastal Climate Adaptation Resources

An archive of adaptation resources such as guidebooks, tools, and state and local plans as well as a blog about coastal concerns by NOAA's Coastal Service Center. Users can parse resources by states or category.

TreeFlow

TreeFlow is a comprehensive web resource for tree-ring reconstructions of streamflow and climate, providing easy access to reconstruction data as well as information about how the data were developed, and can be used. Originally developed by researchers at the Climate Assessment for the Southwest, TreeFlow has a growing collection of tree ring constructions for river basins throughout the Western United States.

Southwest Climate Change Network

The Southwest Climate Change Network is a virtual community for scientists, other experts, decision makers, and the public to share information on climate change and collaborate on solutions. The site provides static and dynamic content and encourages readers to engage with each other and the scientists behind the site and ask questions about what matters to them when it comes to climate in the Southwest.

Southwest Climate Outlook

The Climate Assessment for the Southwest puts out monthly outlooks for the region. These outlooks include a look at last month's temperature and precipitation data, the current state of El Niño/La Niña and reservoir levels, and forecasts for temperature, precipitation, and streamflow. Additional seasonal sections of the outlook include wildland fire and snowpack updates. Archives are also available online.
