The National Climate Assessment assesses the science of climate change and its impacts across the United States, now and throughout this century. It documents climate change related impacts and responses for various sectors and regions, with the goal of better informing public and private decision-making at all levels.

This video features residents of Shishmaref, Alaska, plus environmental journalist Elizabeth Kolbert and scientist John Holdren, exploring the human impacts of global climate change.

The coral reefs of the South Pacific island nation of Vanuatu are the backbone of the island's environmental and economic health. Today they face destruction from a silent predator that can rapidly decimate an entire reef. In this video, students learn about how a starfish is destroying the coral reefs of Vanuatu and how the islanders are adapting.

In this video, learn how communities in the arid high-mountain region of Ladakh rely on glacial water to feed streams and water crops during the spring and summer months. Global warming is dramatically reshaping the future of these areas. Meet a Ladakhi teacher and engineer who devised a method to capture and store glacial runoff into magnificent ice pyramids that are used as water resources throughout the summer and during peak agricultural months.

In this video, an entrepreneur is finding new ways to manage the invasive Asian carp problem in the Mississippi and Ohio rivers. Once introduced to help mitigate an algae problem, the carp became invasive. This video highlights how the local community has adapted to the issue, including how they have gained ideas about how to utilize the carp from other cultures to help mitigate the issue.

This video follows biologist Gretchen Hofmann as she studies the effects of ocean acidification on sea urchin larvae.

This video uses Bangladesh as a case study by describing climate change adaptation strategies being implemented in Bangladeshi communities as well as in other countries.

A short video that discusses how changing climate is affecting the population of AdÃlie penguins.

After the Ice: Our Food discusses changes in historic food sources for Arctic Native Americans. Global climate change is altering yearly cycles of both ice coverage and depth in the Bering Sea. Changes in the ice affect the way local native groups hunt in order to feed their community.

This 7-minute video illustrates how the historic homeland for Arctic Native Americans is being affected by climate change. Shorefast ice and pack ice are present for a shorter part of the year. This has profound affects on the way of life in the Bering Sea region, to the point where the community may have to relocate.

This video discusses how the historic way of life for Arctic Native Americans has changed. Global climate change is altering the ice cycle (yearly coverage, depth, and persistence) in the Bering Sea and weather patterns. Changes in the ice affect the way local native groups are able to hunt for food, and maintain their community.

In Florida's humid climate, strawberry growers are in a constant battle with two kinds of fruit rot. Using a decision support system, they can save money by spraying fields only when the plant diseases are a threat.

This video provides a detailed description of the habitat of the American Pika and how this organism may serve as a climate indicator species because they have a relatively narrow ecological niche and specialized habitat.

In this activity, students explore how the timing of color change and leaf drop of New England's deciduous trees is changing.

Living Atlas Indicators of the Planet provide the user with up-to-date data, maps, graphs, charts, animation and other visuals to explore the science of climate and environmental change. 18 indicators from Air Quality to Women in Parliament can be explored.

This article and slide show from the New York Times, features several scientists from the University of Alaska, Fairbanks, who study the effects of thawing permafrost in Alaska.

Using Landsat 8 imagery from before and after the 2015 wildfire season in Glacier National Park, Montana, learners calculate the damage using a Normalized Burn Index, digitize the burn area, and publish to ArcGIS Online.

This easy-to-understand video animation describes drought and explains the different categories of drought used by the drought monitor. It discusses the effects of and contributions to drought, what the implications of the different drought levels are, and puts the drought maps into context to understand how the impacts vary geographically (e.g. drought in Nevada vs Kansas - one could affect tourism, the other agriculture). It also touches on how the development of maps/drought severity is determined and how it might vary geographically. The animation provides a basic overview of statistics and percentiles and the concept of '100 year events.'

In this activity, students explore the web-based U.S. Forest Service Climate Change Atlas to learn about projected climate changes in their state and how suitable habitat for tree and bird species is projected to change by 2100.
