Students calculate the cost of the energy used to operate a common three-bulb light fixture. They then compare the costs and amount of CO2 produced for similar incandescent and compact fluorescent light bulbs. Students also do a short laboratory activity to visualize why two bulbs, which give off the same amount of light, use different amounts of electrical energy.

This is the seventh of nine lessons in the 'Visualizing and Understanding the Science of Climate Change' website. This lesson addresses climate feedback loops and how these loops help drive and regulate Earth's unique climate system.

This NBC Learn video features climate scientists doing their research on Mt. Kilimanjaro to study the climate of the past. The scientists put the recently observed changes on the glacier into perspective by comparing past climate fluctuations, stressing that the current observed rate of change is unprecedented.

In this EarthLabs activity, learners explore the concepts of coral bleaching, bleaching hot spots and degree-heating weeks. Using data products from NOAA's Coral Reef Watch, students identify bleaching hot spots and degree-heating weeks around the globe as well as in the Florida Keys' Sombrero Reef to determine the impact higher-than-normal sea surface temperatures have on coral reefs.

This video is accompanied by supporting materials including background essay and discussion questions. The focus is on changes happening to permafrost in the Arctic landscape, with Alaska Native peoples and Western scientists discussing both the causes of thawing and its impact on the ecosystem. The video shows the consequences of erosion, including mudslides and inland lakes being drained of water. An Inuit expresses his uncertainty about the ultimate effect this will have on his community and culture.

This hands-on activity is a kinesthetic game illustrating the dynamics of the carbon cycle. Acting as carbon atoms, students travel from one carbon reservoir to another; at each reservoir they determine, by rolling dice, how long they stay in the reservoir or how likely it is that they will move to another carbon reservoir.

This video explores what scientists know about how changes in global climate and increasing temperatures affect different extreme weather events.

This lesson plan engages students in a real-life exploration of climate change as it is affected by greenhouse emissions from vehicles. The aim of this activity is for students to realize the impact of vehicle use in their family and to give students the opportunity to brainstorm viable alternatives to this use.

Wednesday, February 18th – 4:00pm PT/7:00pm ET

The National Climate Assessment, released in May of 2014, summarizes the impacts of climate change on the United States, touching on many disciplines: earth science, biology, human health, engineering, technology, economics, and policy. Explore the document with a lead NCA author, then learn about related educator resources with Minda Berbeco from the National Center for Science Education. Discover how to bring these resources into classroom lessons, engage students in data collection and analysis, share visualizations and citizen science projects. 

Focus this month will be on the Southwest region. Watch for additional regions to be featured in upcoming “Ask US” sessions.

The opportunities and pathways for careers in natural resources and sustainability areas are diverse and the conversation between employers and higher education is only just beginning. This workshop will focus on articulating the breadth of opportunities and identifying the knowledge and skills that are pathways to different types of employment.
