In this lesson, students discover how changes in climate over the Colorado watershed are reducing the amount of fresh water available in the river. They also see how the population of the region that uses this water has grown, resulting in increasing demands on a dwindling resource. The case study presented in this lesson introduces students to a real drought that has been developing in the Colorado River basin for many years. The Colorado River is the major source of water for people in the driest part of the United States. More than 30 million people in 7 states depend on this river as the primary source of their water.

In this lesson, students will contemplate what the future might hold for climate and the cryosphere. In the first part of the lab, they will learn about what climate models predict Earth's climate will be like in the future. In Part B, they will consider potential changes in sea level that might be brought about by warming temperatures and melting ice.

Over the past 40 years, some lobstermen in South Thomaston, Maine, say that they could "set their watches” by the start of the lobster shedding event each season. In 2012, though, extreme warm ocean temperatures—an ocean heat wave—combined with early and repeated lobster shedding. The obvious changes in lobsters during this event galvanized many lobstermen to take the impacts of climate change seriously.

In the Arizona desert, farmers depend on an ample supply of irrigation to grow their crops. As climate changes, irrigation managers face a host of issues to keep the water flowing.

Students will prepare and participate in a mock trial to try to assign responsibility for the consequences of climate change from the build up of CO2 emissions in the earth's atmosphere.

This article highlights how the increase in carbon dioxide is contributing to a greener planet.

In this brief animated video, students learn about increasing temperatures and associated effects on Earth.

Students learn about changes to Earth's systems and how this may be related to global climate change in this brief animated video.

In this lesson, students will describe a climate model and what it measures and investigate the overall weather trend that has emerged since the 1970s.

Studenst will simulate the layers of ocean water and explore their densities; afterwhich they will collaborate on the answers to why their observations occurred.

In this lesson, students learn what organisms are affected by ocean acidification. They will then take on the role of one of the stakeholders affected by ocean acidification and create a poster to address their issue(s). They will also participate in a mock conference to address the effects of ocean acidification and discuss solutions to reduce ocean acidification.

In this unit students will learn what ocean acidification is and why it is happening, describe ways in which individual species and marine ecosystems might respond to ocean acidification, and describe how ocean acidification will impact the ability of oceans to sequester carbon.

In activity Part A, students will analyze a time-series graph to search for relationships between trends in atmospheric CO2, dissolved CO2 in seawater, and changes in ocean pH. Then, they will carry out a class experiment on the effects of increased amounts of CO2 on pH in sea water. This activity also focuses on understanding pH and ocean acidity. Included is a short interactive video about acids, bases, pH, and ions.

Students create a video that documents unrehearsed interviews with multiple persons-on-the-street about a specific question or issue in climate science. To produce a compelling product, students will need to both understand the underlying science themselves, and be able to conduct and document a series of interviews to elicit interviewees' understanding of the science as well.

In this problem-based learning activity, students are presented with the scenario that they are representatives of an organization that is tasked with evaluating the potential effects of a warming climate on New England forests. Student worksheets, teacher guide, and assessment rubric are included. The resource is part of Forests: A Sticky Situation, from the lesson series The Potential Consequences of Climate Variability and Change.

For irrigated crops, knowing when and how much water to apply has long been a matter of experience and guesswork. In a changing climate, new technology can reduce this uncertainty, enabling farmers to make every drop of water count.

Changing conditions spur a utility in Washington, D.C., to consider and address its future climate vulnerabilitie

Students research a climate change topic of their choice and create a Public Service Announcement (PSA) that communicates their understanding of the science, raises awareness about the causes and consequences of climate change and motivates people to take action in their communities, families and their own lives.
