El Niño is marked by the appearance from time to time of warm water in the central and eastern Pacific Ocean. The end result of the evaporative process that follows is excessive rainfall.

This course will explore how Americans have confronted energy challenges since the end of World War II. Beginning in the 1970s, Americans worried about the supply of energy. As American production of oil declined, would the US be able to secure enough fuel to sustain their high consumption lifestyles? At the same time, Americans also began to fear the environmental side affects of energy use. Even if the US had enough fossil fuel, would its consumption be detrimental to health and safety? This class examines how Americans thought about these questions in the last half-century. We will consider the political, diplomatic, economic, cultural, and technological aspects of the energy crisis. Topics include nuclear power, suburbanization and the new car culture, the environmental movement and the challenges of clean energy, the Middle East and supply of oil, the energy crisis of the 1970s, and global warming.

In an active way, students discover a few critical facts about how we use energy and how much energy we use. Each student has a "clue," some of which are pertinent energy facts and others are silly statements that are clearly unrelated to the topic. Students mingle and ask each other for clues until they have collected all the facts they need. This provides a more interactive way to communicate energy statistics, compared to a lecture and introduction with board work. The goal is to introduce students to some key terms and issues associated with energy as a necessary prerequisite for the remainder of the unit.

A survey of how America has become the world's largest consumer of energy. Explores American history from the perspective of energy and its relationship to politics, diplomacy, the economy, science and technology, labor, culture, and the environment. Topics include muscle and water power in early America, coal and the Industrial Revolution, electrification, energy consumption in the home, oil and US foreign policy, automobiles and suburbanization, nuclear power, OPEC and the 70's energy crisis, global warming, and possible paths for the future.

Our world runs on energy - without it, things come to a screeching halt, as the recent hurricanes have shown. Ever stop to wonder what our energy future is? What are our options for energy, and what are the associated economic and climatic implications? In \Energy and the Environment\" we explore these questions, which together represent one of the great challenges of our time - providing energy for high quality of life and economic growth while avoiding dangerous climate change. This course takes an optimistic view of our prospects, and we'll see how shifting to renewable energy can lead to a viable future.

Learn about environmental chemistry through engaging, bitesize animated videos. The videos are organised into chapters including: the earth, the air, water, rocks, metals and their reactivity, global warming, carbon chemistry, fuels and recycling.

This course explores the proper role of government in the regulation of the environment. It will help students develop the tools to estimate the costs and benefits of environmental regulations. These tools will be used to evaluate a series of current policy questions, including: Should air and water pollution regulations be tightened or loosened? What are the costs of climate change in the U.S. and abroad? Is there a "Race to the Bottom" in environmental regulation? What is "sustainable development"? How do environmental problems differ in developing countries? Are we running out of oil and other natural resources? Should we be more energy efficient? To gain real world experience, the course is scheduled to include a visit to the MIT cogeneration plant. We will also do an in-class simulation of an air pollution emissions market.

The forests of North America have seen plenty of change in a pretty short period of time, at least geologically speaking. Up until about 18,000 years ago, the Laurentide Ice Sheet covered Canada and much of the eastern United States. When temperatures climbed and the ice sheet retreated, forests gradually reemerged. But how? Did pockets of trees find refuge in sheltered areas during the Ice Age? Or were all tree species pushed to the southern tier of the United States, only to spread north again after the ice disappeared? Scientists still debate the topic, but one thing is clear: today’s forests in the eastern United States bear little resemblance to post-glacial forests. Starting with European colonial settlers and marching through four centuries of development, drought, and fire, the tree cover of North America became fragmented.

The year is 2050 and your once-idyllic beachfront vacation home is now flooded up to the second story. The crab your family has enjoyed every Christmas for as long as you can remember has now become an endangered species. The oceans have changed. In Earth 540, Oceanography for Educators, we explore the mechanisms that lead to sea level rise and ocean acidification. We strive to understand how natural processes such as ocean currents, the gulf-stream, tides, plate tectonics, and the Coriolis Effect, affect our oceans and ocean basins. We then predict how man-made issues such as climate change and overfishing will affect our beloved waters and our livelihoods. Want to see into the future? Then this course is for you!

Species extinction is happening at an alarming rate according to scientists. In this lesson, students are asked to consider why extinction is a problem that we should concern us. They are taught that destruction of habitat is the main reason many species are threatened. The lesson explores ways that engineers can help save endangered species.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"As global warming persists, it’s becoming clear that even the smallest forms of life need protection, including in the cold deserts of Antarctica. But scientists know very little about the microbes that make their home in Antarctic soil, leaving the picture of biodiversity and ecological change in this region incomplete. Now, researchers from Australia are filling in the blanks. They’ve conducted the first-ever microbial biodiversity report for two Antarctic regions: the extremely dry Vestfold Hills and the Windmill Islands. Bacterial communities in both areas were dominated by microbes of the metabolically and physiologically diverse phylum Actinobacteria, but the Vestfold Hills showed a higher prevalence of members of the Bacteriodetes phylum, likely due to the saltier soils found in this region. Overall, the observed diversity of community members suggests that microbes have found a way to share their environment equitably..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

In partnership with the National Science Digital Library and Apple, NCAR and UCAR offer podcasts that provide a brief and accessible overview on climate and climate change. These podcasts, short 5-8 minute videos you can download on your computer or iPod, are a part of the NSDL on iTunes U collection.

Human-caused climate change represents one of the great environmental challenges of our time. As it is inextricably linked with issues of energy policy, a familiarity with the fundamentals of climate change is critical for those looking to careers in the energy field. To appreciate the societal, environmental, and economic implications of policies governing greenhouse gas emissions, one must understand the basic underlying science. METEO 469 serves to lay down the fundamental scientific principles behind climate change and global warming. A firm grounding in the science is then used as a launching point for exploring issues involving climate change impacts and mitigation.
