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 worksheet-based activity, students review global visualizations of incoming sunlight and surface temperature and discuss seasonal change. Students use the visualizations to support inquiry on the differences in seasonal change in the Northern and Southern Hemispheres and how land and water absorb and release heat differently. The activity culminates in an argument about why one hemisphere experiences warmer summers although it receives less total solar energy.
Navigating to New Shores: Seizing the Future for Sustainable & Resilient U.S. Freshwater Resources
October 9, 2014
Based on 6 years of work, The Johnson Foundation examines challenges associated with quality, availability, & resilience of U.S. freshwater resources due to climate change, aging infrastructure, & extreme events.
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.
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.
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.
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 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.
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.
