Climate change videos address a variety of topics including how climate changes are affecting the environment, and what we can do to stop it. They can also help to educate and motivate people. Some provide a good introduction to key issues while others show how to take action to reduce emissions.
Understanding the relationship between climate change and greenhouse gas emissions is crucial. The graph below shows how the CO2 emissions of the top emitters from each country have changed over the past 150-years. This shows that greenhouse gas emissions have been closely related to temperature over the past 150 years, meaning that our climate has been warming steadily for more than 30 years.
The environment has already suffered many severe effects from climate change. These include melting the Greenland and Antarctica Ice Sheets, rising sea levels and shrinking oceanic capacity. It has the potential for increasing fire risk in certain parts of Russia, Australia and South Africa. Not only are these risks, but the loss or destruction of native species can also pose a threat to human life.
"Chasing Ice," a video about climate change, is one of the most popular. It features a photojournalist in a mission to find evidence of climate changes. PBS offers this series. The episodes feature interviews of scientists and experts who discuss the science behind climate changes.
Another series, "Extreme Engineering and Architecture", focuses on technologies to lower greenhouse gas emissions. They also explore extreme architecture, such as building structures on stilts to accommodate rising sea levels. Many of these videos are under copyright, but philanthropists have the opportunity to purchase the rights.
John Holdren returns to the program to discuss geoengineering's tradeoffs. He is also the director at the Woods Hole Oceanographic Institute. He also discusses the upcoming Arctic Ocean albedo turn.
You can also find many more great videos about climate change on the Internet. These include 'Global Warming: The Signs and the Science,' made by ETV in South Carolina. This documentary film gives an excellent overview about the causes, consequences, solutions, and implications of global warming.
Another great documentary is "What's Up with the Weather?" PBS 18 aired this documentary. Episode 8 discusses climate change and the weather. While this video is primarily focused on overpopulation, it does highlight some of the negative impacts of climate change.
Climate change is causing more severe weather in the United States than it has ever been. The climate made last year's heatwave thirty times more likely. Over the past five years, the rate of melting off the Antarctic glacier has increased.
As a result of this, oceans are becoming more acidic and the capacity to absorb carbon dioxide is decreasing. Oceans could also rise up to 1.5 inches per decade by 2050. The threat of flooding is increasing for coastal cities as well as islands.
FAQ
What are the roles of greenhouse gases in climate changes?
Greenhouse gases play a major role in climate change. They act as an invisible blanket that wraps around the Earth, trapping heat radiation and warming it. Without them, the planet might be much colder that it is now.
The human activity of burning fossil fuels, or other industries that generate emissions, can create greenhouse gases. These activities are increasing in number, which means that more heat is trapped in our atmosphere. This can lead to extreme weather events and rising temperatures.
Carbon dioxide (CO2) is the most common greenhouse gas. It is produced when fossil fuels like coal, oil and gas are burned. Other major contributors to climate changes include methane, nitrous oxide and fluorinated gases (F-gases).
Because of human activities, the concentrations of greenhouse gases have increased substantially since preindustrial days. Global warming has resulted in an increase of temperatures around the world and in our oceans. It is also causing changes such as more intense storms and droughts, melting glaciers, and rising sea levels.
To avoid further damage from climate change, humans need to reduce their emissions of greenhouse gases by transitioning away from fossil fuels towards renewable energy sources like solar or wind power. Reforestation and other agricultural practices can be used to absorb more CO2 from air. These actions will help reduce atmospheric concentrations in greenhouse gases and create a healthier ecosystem for all life.
What are the causes for climate change
Climate change, which is a global phenomenon, has been driven by an increased amount of greenhouse gases from human activity. The increase was primarily caused by fossil fuel burning to generate electricity and transport. These emissions cause more of the sun's warmth to be trapped in Earth's atmosphere, leading to rising global temperatures.
Climate change can also be caused by population growth, land clearing, destruction of ecosystems and energy consumption, over-grazing, and deforestation. This further decreases the number natural carbon sinks that absorb CO2 in the atmosphere. Changes in solar radiation and other natural forces can also contribute to climate changes.
These human activities combined result in Earth being unable to adequately balance its energy resources, which has led to an average global temperature increase of 1 degree Celsius from pre-industrial times. Glaciers melt faster than they form and sea levels rise as oceans absorb most of this heat energy. Other negative consequences include water scarcity, droughts and extreme weather events like flooding and hurricanes.
We must reduce our carbon footprint, and begin reducing our emissions immediately to protect ourselves from the increasing impacts of climate change. Along with reducing our dependence upon fossil fuels to generate electricity, it is important to invest in renewable sources like wind turbines or solar cells that do not emit harmful pollutants into nature. Other sustainable practices like reforestation can also help restore some balance around these delicate planetary cycles we rely on for survival.
How does human activity contribute to climate change?
Climate change is caused primarily by human activity. In fact, according to the Intergovernmental Panel on Climate Change (IPCC), humans are responsible for more than 70% of all global warming since the mid-20th century.
Burning Fossil Fuels: Burning fossil fuels such as coal, oil, and gas releases carbon dioxide into the atmosphere. This increases the already high levels of atmospheric CO2, which acts as a greenhouse gas by trapping heat from Earth's sun and increasing temperatures. This leads to higher ocean levels as Arctic ice melts and scrambles weather patterns around the world leading to deadly storms, droughts, and floods which could affect food production and endanger human health.
Deforestation: Deforestation knocks out trees which sequester atmospheric carbon dioxide in their trunks when they take it up during photosynthesis. The albedo is also increased by cutting down forests. It refers to the amount of solar radiation reflected back into space. As well decreases local air quality with deforestation being linked permanently with respiratory issues.
Farming: The animal agriculture industry contributes 14%-18% of total anthropogenic emissions of greenhouse gases globally every year. Because animal waste is rich in methane bacteria, large amounts of methane are released into the atmosphere. This can lead to a significant increase in global warming.
Conclusion: Human activity has had a profound impact on the environment for centuries. However, technology has made it possible to leverage green innovation and make eco-friendly efforts to combat climate change. This will ensure that everyone is safe while prospering in nature.

How To
How to Incorporate Sustainable Practices into Your Daily Life to Fight Climate Change
One way you can incorporate sustainable practices into your daily life is by reducing your consumption of resources such as food, clothes, and energy. Don't buy new items every single day. Instead, shop secondhand. Also, vegetarian meals can be a great way to cut down on methane from livestock production. Turn off lights whenever you are leaving a room in order to conserve energy.
One way to combat climate change, is to decrease emissions from transportation sources like planes and cars by carpooling. In place of traditional fossil fuels, we can choose to use renewable power sources such solar panels to generate electricity at our homes. It is crucial to support measures at the policy level that encourage clean air regulations in order to make climate change mitigation work. Also, engaging with other citizens on issues such plastic pollution reduction and deforestation will help to create more conscious citizens that will take action.
