Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Define global climate change
Summarize the effects of the Industrial Revolution on global atmospheric carbon dioxide concentration
Describe three natural factors affecting long-term global climate
List two or more greenhouse gases and describe their role in the greenhouse effect

Meet Professor Cathy Drennan, whose research focuses on a protein inside microorganisms and how it converts carbon dioxide, a greenhouse gas that accelerates climate change, into energy.

Retrieve information from multiple sources of Envirofacts' System Data for your area of interest. using zip code, city, or county information.

Understand the process that must occur to create carbon dioxide. What is the role of carbon dioxide in our atmosphere? A video illustrating the carbon cycle is available.

Earth's atmosphere contains greenhouse gases. Find out what these gases are and where they come from. Also link to other information about how greenhouse gases contribute to climate change.

Students take a closer look at cars and learn about some characteristics that affect their energy efficiency, including rolling resistance and the aerodynamics of shape and size. They come to see how vehicles are one example of a product in which engineers are making changes and improvements to gain greater efficiency and thus require less energy to operate.

Students learn how the greenhouse effect is related to global warming and how global warming impacts our planet, including global climate change. Extreme weather events, rising sea levels, and how we react to these changes are the main points of focus of this lesson.

Is the hydrogen car the answer to global warming? This video segment adapted from NOVA/FRONTLINE looks at the pros and cons of this developing technology. Uses popups. [1:26]

Bioproducts are chemicals, energy, and materials that are produced from renewable biological resources. This unit features 3 lessons and 4 files. Lessons are aligned to NGSS.

Students learn about the advantages and disadvantages of the greenhouse effect. They construct their own miniature greenhouses and explore how their designs take advantage of heat transfer processes to create controlled environments. They record and graph measurements, comparing the greenhouse indoor and outdoor temperatures over time. Students are also introduced to global issues such as greenhouse gas emissions and their relationship to global warming.

Do you ever wonder how a greenhouse gas affects the climate, or why the ozone layer is important? Use the sim to explore how light interacts with molecules in our atmosphere.

How do greenhouse gases affect the climate? Explore the atmosphere during the ice age and today. What happens when you add clouds? Change the greenhouse gas concentration and see how the temperature changes. Then compare to the effect of glass panes. Zoom in and see how light interacts with molecules. Do all atmospheric gases contribute to the greenhouse effect?

View this clay animation video by NOVA to examine the reasons sea levels will not uniformly rise around the world. Factors affecting sea levels include climate change, the natural tilt of the ocean, expansion of water, and gravity. Closed caption available. [2:52]

This resource provides statistical evidence, backgrounders, FAQs, climate impact reports, and suggested solutions to the global problem.

Students determine their carbon footprints by answering questions about their everyday lifestyle choices. Then they engineer plans to reduce them. Students learn about their personal impacts on global climate change and how they can help the environment.
