It's no secret that greenhouse gases warm the planet and that this has dire consequences for the environment whole islands swallowed up by rising seas, animal and plant species stressed by higher temperatures, and upsets in ecological interactions as populations move to cooler areas. However, carbon dioxide has another, less familiar environmental repercussion: making the Earth's oceans more acidic. Higher levels of carbon dioxide in the atmosphere mean that more carbon dioxide dissolves in the ocean. This dissolved carbon dioxide forms carbonic acid the same substance that helps give carbonated beverages their acidic kick. While this process isn't going to make the ocean fizzy anytime soon, it is introducing its own set of challenges for marine organisms like plankton and coral.

We will explore the changing political choices and ethical dilemmas of American scientists from the atomic scientists of World War II to biologists in the present wrestling with the questions raised by cloning and other biotechnologies. As well as asking how we would behave if confronted with the same choices, we will try to understand the choices scientists have made by seeing them in their historical and political contexts. Some of the topics covered include: the original development of nuclear weapons and the bombing of Hiroshima and Nagasaki; the effects of the Cold War on American science; the space shuttle disasters; debates on the use of nuclear power, wind power, and biofuels; abuse of human subjects in psychological and other experiments; deliberations on genetically modified food, the human genome project, human cloning, embryonic stem cell research; and the ethics of archaeological science in light of controversies over museum collections.

A team of middle school students in Baton Rouge research global warming and produce their take on the subject in this witty 30-second animated short

In this lesson, students investigate whether other parts of the world are changing and getting hotter just like Colorado.

This course explores the physical processes that control Earth's atmosphere, ocean, and climate. Quantitative methods for constructing mass and energy budgets. Topics include clouds, rain, severe storms, regional climate, the ozone layer, air pollution, ocean currents and productivity, the seasons, El Ni–o, the history of Earth's climate, global warming, energy, and water resources.

This series looks at the Oxford Martin School's academics and how their research is making a difference to our global future. The series will be of interest to people who are concerned about the future for the planet, how civilisation will adapt to emerging problems and issues such as climate change, over population, increased urbanisation of populations and the creation of vaccines to fight against future pandemics. The Oxford Martin School academics explain their various research topics in an accessible and thoughtful way and try to find practical solutions to these issues.

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

By the end of this section, you will be able to:Define global climate changeSummarize the effects of the Industrial Revolution on global atmospheric carbon dioxide concentrationDescribe three natural factors affecting long-term global climateList two or more greenhouse gases and describe their role in the greenhouse effect

The Council on Foreign Relation's (CFR) "Deforestation in the Amazon" InfoGuide provides a compelling look at the causes and consequences of deforestation in the Brazilian Amazon and is available online in English and Portuguese. CFR InfoGuides are a multimedia series to promote understanding of complex foreign policy issues.

Students are introduced to the concept of energy cycles by learning about the carbon cycle. They will learn how carbon atoms travel through the geological (ancient) carbon cycle and the biological/physical carbon cycle. Students will consider how human activities have disturbed the carbon cycle by emitting carbon dioxide into the atmosphere. They will discuss how engineers and scientists are working to reduce carbon dioxide emissions. Lastly, students will consider how they can help the world through simple energy conservation measures.

In this video adapted from the Arctic Athabaskan Council, learn how warmer temperatures in the Arctic are transforming the landscape, triggering a host of effects such as permafrost thawing and insect infestations.

This is an undergraduate introductory laboratory subject in ocean chemistry and measurement. There are three main elements to the course: oceanic chemical sampling and analysis, instrumentation development for the ocean environment, and the larger field of ocean science.
This course is offered through The MIT/WHOI Joint Program. The MIT/WHOI Joint Program is one of the premier marine science graduate programs in the world. It draws on the complementary strengths and approaches of two great institutions: the Massachusetts Institute of Technology (MIT) and the Woods Hole Oceanographic Institution (WHOI).

This video adapted from KTOO takes a look at Earth's warming and cooling cycles and the current atypical trend of warming that is impacting the glaciers in Alaska's Inside Passage.

Environmentalists passionately opposed to a giant pipeline that would transport crude oil from the tar sands of Canada to the Gulf coast are going head-to-head with proponents of the project. Students explore the controversy surrounding the Keystone XL pipeline and the strategic questions it raises for environmentalists.

This article features children's literature about weather, climate, and climate change. What’s the difference between weather and climate? How do scientists observe, measure, and predict weather phenomena? How is Earth’s climate changing, and why? This month’s bookshelf will help students develop a solid grasp of weather-related concepts. It will also introduce students to global warming and climate change and inspire them to do what they can to combat the problem.

Use this site to learn about the science of climate change and its potential effects on our nation's wildlife and their habitats.

Host Harry Kreisler welcomes scientist Lars-Erik Liljelund, Director General of the Swedish Environmental Protection Agency, for a discussion of Swedish policy for addressing climate change and global warming. He reflects on his own career which combines work in public policy and science. He also talks about the distinctive quality of the global warming problem and the obstacles for finding and implementing solutions. 54 min)
