This chapter provides a summary of the material discussed in the previous twelve chapters. Some of the topics reviewed include: the greenhouse effect, global warming, and climatic changes. This chapter also highlights the consequences associated with global warming from major cities to the rural country side. Viewers also explore ways to lessen the impact of global warming and how to adapt to the new climate conditions. Chapter 13 of Air: Climate Change Series.

Earth’s climate is changing in a big way, and it’s because there's more carbon dioxide in the atmosphere than at any point in human history. But Earth’s climate has changed before. How are scientists studying the impact of human behavior on climate? They are collecting ice cores and analyzing the tiny bubbles of ancient atmosphere trapped in the cores. Part of the "It's Okay to Be Smart" series.
The Large Lakes Observatory (LLO) helps an interdisciplinary group of scientists use oceanographic research approaches to investigate the mysteries of large lakes. With support from the National Science Foundation, LLO scientists work to better understand the biology, chemistry, physics, and geology of these bodies of water. In the summer of 2011, LLO scientists completed a 17- day research cruise on Lakes Superior, Huron, and Erie, focusing on how a buildup of nitrates may impact the ecology of all the Great Lakes. They say a greater understanding of lakes will ultimately improve our management and conservation efforts.
WildFIRE PIRE is a 5-year National Science Foundation project focused on the causes and consequences of fire in the past, present, and future. Join scientists from around the world as they endeavor find out more about global wildfire through field expeditions to some of the wildest places on earth. Part of WildFIRE PIRE series.
Host Jessica Robertson visits Montana and gathers questions from individuals visiting Glacier National Park. They want to know how climate change is impacting glaciers. Scientists from the United States Geological Survey (USGS) provide the answers and information on how to learn more about climate change.
Host Jessica Robertson gathers questions from individuals in downtown Denver, Colorado. They want to know how Colorado is affected by climate change. Scientists from the United States Geological Survey (USGS) provide the answers and information on how to learn more about climate change.
Host Jessica Robertson visits middle and high school students in Mt. Airy, NC. They want to know if all scientists agree that climate change is occurring. Scientists from the United States Geological Survey (USGS) provide the answers and information on how to learn more about climate change.
Host Jessica Robertson travels across North and South Carolina to gather questions about climate change. Scientists from the United States Geological Survey (USGS) provide the answers and information on how to learn more about climate change.
Types of climates and climate zones are explained using familiar examples. This video explores the plants and animals that inhabit different climates, the influence of temperature and precipitation on climate, and the causes of climate change over time. Other topics covered include topography, prevailing winds, rain shadow, altitude, climate, latitude, polar zone, temperate zone, and tropical zone.
Throughout the Pleistocene Epoch, the range of the woolly rhino grew and shrank in sync with global climate. So, what caused the climate and the range of the woolly rhino to cycle back and forth between such extremes? Part of the “Eons” series.
This video focuses on important characteristics of climate and explains how ice cores tell the story of climate change. It also clarifies the concept of proxies and reveals the measures that climate scientists use as proxies. Part of the "Ice Cores: Unlocking Past Climates" series.
Argentina is experiencing a decrease in native forests due to deforestation. As part of the process, only fifteen trees are replaced for every hundred cut down. This depletion of natural vegetation has devastating consequences for the environment. These consequences are immediate and long-term, if not reversed. Deforestation affects climate, biodiversity, conservation, and water absorption. Chapter 5 of Air: Climate Change Series.
Is it possible that climate change could have kick-started the end of antiquity and heralded the beginning of the Dark Ages? New scientific insights point to the impact of the eruption of the Ilopango Volcano in Central America. The eruption was violent and propelled ash into the stratosphere. As a result, the sun struggled to break through the ash. The following 10 years were extraordinarily cold, and this was the beginning of a time period marked by famine, war, and an almost complete loss of cultural heritage. Part of the "How Climate Made History" series.
Sea spray aerosols occur naturally in the salty ocean air, and there’s much more in each of those tiny bursting bubbles than salt. They’re bursting with ocean life, from bacteria to phytoplankton--even viruses. Because sea spray aerosols seed clouds, they affect the climate. With support from the National Science Foundation (NSF), atmospheric chemist Kimberly Prather of the University of California, San Diego, and chemist Vicki Grassian of the University of Iowa are leading a team of scientists around the country who are working to better understand what role sea spray aerosols play in weather and climate change climate models. Part of the National Science Foundation Series “Science Nation.”
For millennia, hurricanes have threatened the Eastern United States, the Caribbean, and parts of Latin America. But changes to global climate have serious consequences for the future. For example, rising sea-levels mean that storm surge from hurricanes will impact ever further inland. In episode three, specialists discuss why they believe that hurricanes will become less frequent but increasingly powerful. Insight and interviews from leading experts such as Nobel Prize-winning climatologist, Jean-Pascal Van Ypersele, explore the preparations needed to withstand a super storm. Part of the "Hurricane, the Anatomy" series.
Powerful forces have forged the conditions on Earth that have made life possible. The millennia have been witnesses to the formation of the planet: its singular position in relation to the sun, the evolution of the continents, and the birth of entire mountain chains. All of these elements combine to create Earth’s constantly changing climate. Homo sapiens emerge into this unpredictable and violent world, fighting for survival from the start. It is these early humans’ ability to adapt that allows them to triumph even in the face of incredible adversity and sets the path for modern man. Part of the "How Climate Made History" series.
The Earth has been knocked off its axis, and the seasons are changing rapidly. Superhero Autumn Ray has to return the Earth's axis to its correct angle. As she works to slow the change of seasons, she explains the relationship between the tilt of the Earth's axis and the seasons. Part of "The Science of Climate" series.
The tourism industry not only generates significant revenue for locales but also contributes to climate change. Currently, it is estimated that the tourism industry generates about five percent of total greenhouse gas emissions. The percentage is expected to increase by eighty percent by 2035. Climatic conditions are considered a decisive factor attracting people to different geographic areas. However, destinations are beginning to suffer environmental changes as a consequence of tourism. Chapter 6 of Air: Climate Change Series.
Scientist are concerned about the decreasing mass of the world's glaciers. Due to numerous environmental factors, glaciers that were once abundant in the Northern regions are now half of their original size. Climate change has become a very real and dangerous impact for the planet. Part of the "Glacier Series."
Just like animals and humans, plants have their own microbiomes, which help them stay healthy and provide them with nutrients. Some of these microbiomes include symbiotic fungi that can help certain plants deal with tremendous environmental stress, including heat stress. Scientists are studying how fungi like this might be used to help alleviate the impacts of climate change on food crops. Part of the "I Contain Multitudes" series.
