Climate change videos cover many topics including how climate change affects the environment and what you can do about it. These videos can be used to educate and engage the public. They can be used to introduce key issues and others to explain how to reduce emissions.
One of the most important things to understand is the relation between greenhouse gas emission and climate change. The graph below shows how the CO2 emissions of the top emitters from each country have changed over the past 150-years. This shows how greenhouse gases have been closely correlated with temperature for the past three decades.
Many devastating environmental effects have already been caused by climate change. These include melting of Greenland's ice sheets and Antarctica's ice caps, an increase in sea level rise and a shrinking capacity for the oceans. It has the potential for increasing fire risk in certain parts of Russia, Australia and South Africa. The loss of native species could also have dangerous consequences for human lives.
"Chasing Ice" is one of the best climate change videos. It follows a photojournalist on a mission, to record evidence of climate change. PBS is streaming this series. The episodes feature interviews with scientists and experts and look at the science behind climate change.
Another series, titled "Extreme Engineering and Architecture", is focused on technologies to reduce greenhouse gases emissions. They also explore extreme architecture, such as building structures on stilts to accommodate rising sea levels. These videos are often under copyright. Philanthropists can purchase the rights.
John Holdren returns to the program to discuss geoengineering's tradeoffs. He is director for the Woods Hole Oceanographic Institute. Also, he discussed the upcoming Arctic Ocean Albedo Flip.
There are many other amazing videos about climate change that you can find on the Internet. ETV South Carolina produced "Global Warming" which explains the science behind the phenomenon. This documentary gives a great overview of global warming's causes, consequences and solutions.
Another excellent documentary is "What's the weather?" PBS's season 18 series aired it. Episode 8 is about climate change. Although the video is focused on overpopulation, it does highlight some adverse effects of climate changing.
The United States is experiencing more severe weather than ever before due to climate change. The climate made last summer's heatwave 30 times more likely. Also, the rate of melting from the Antarctic ice sheet has accelerated over the past five years.
Oceans are becoming more acidic, and their capacity to absorb carbon dioxide is declining. In addition, oceans are expected to rise by as much as 1.5 inches per decade by 2050. At the same time, flooding is a growing problem in coastal areas and islands.
FAQ
How does climate change politics impact global efforts?
Climate change is a controversial issue that has caused a lot of division between nations, governments and individuals. The political stances taken by different actors will impact the implementation measures to combat climate changes. It has been difficult to reach a consensus on the global effort to address this urgent environmental problem.
A majority of scientists agree that climate change caused by humans is real and must be addressed immediately. These politics often hamper global cooperation needed to achieve effective progress in implementing sustainable energy practices.
Many governments around the globe want to protect business interests and enforce policies that restrict business activities. This often clashes with regulations that experts recommend for effectively addressing climate change. Without strong commitments by all countries involved and large-scale international action it is difficult for any state or group to adequately address climate changes through legislation.
The difficulty of reaching a full consensus about the best way to combat climate change is further complicated by differences in power dynamics. Countries with more economic power may appoint themselves to be represented on international bodies for negotiations about the environment. This can lead the to divisive discussions between the countries' interests and the collective interest. Additionally, the potential side effects of implementing radical changes like geoengineering are being heavily debated at both national as well international levels.
A grassroots movement has also struggled against powerful opposition, including corporate ownerships as well-funded lobbyists trying to keep their industries politically favorable. This is especially true when it comes funding research into alternative energy production and enforcing mandates for renewable energy technology. Individual governments need to be clear about the potential rewards and outcomes of making valid progress on the issue. They cannot seek short-term spectacles or gains to gain public support.
It is essential to distribute resources properly to any intervention program, and to be mindful of political divisions within nations, if we want to see an effective coordinated effort to mitigate our current environmental crisis.
What's the potential for climate-change technology?
This global problem is a huge challenge that new technologies can address. From renewable energy sources like solar, wind, and geothermal to energy storage systems like battery packs or thermal tanks, advances in applied science are making it possible for us to transition to a more sustainable future.
To reduce greenhouse gas emissions, new methods of carbon capture can be used. Enhanced agricultural practices can also help to reduce the amount of livestock and soil degradation. Smart grid technology is also possible to be integrated into existing power infrastructure, resulting in an efficiency boost. Furthermore, improved building design can help decrease energy consumption.
The latest synthetic biology methods allow scientists to create organisms that can use green sources of fuel like the CO2 laser as biofuels or alternative feedstocks. This could change the way that transportation is done if petrol-based vehicles are replaced by zero emission electric cars that are powered from clean sources.
Finally, increased investments in digital technology or AI can provide people with more information on their ecological footprints across borders. This will allow them to make more informed decisions regarding their consumption habits. Understanding how we contribute to the carbon production of our planet is key for better stewardship.
What is the role of greenhouse gases in climate change?
Climate change is influenced by greenhouse gases. They act like an invisible blanket around the Earth, trapping infrared radiation and warming the atmosphere. Without them the planet would be much more colder than it currently is.
Human activity can cause greenhouse gases, such as the burning of fossil fuels and other industries that emit emissions. As these activities continue to increase, more heat gets trapped in the atmosphere, leading to rising temperatures and extreme weather events.
Carbon dioxide (CO2), the most potent greenhouse gas, is released by fossil fuels like gas, oil, and coal. Other major contributors to climate changes include methane, nitrous oxide and fluorinated gases (F-gases).
The concentration of greenhouse gases has increased significantly since preindustrial times due to human activities. Global warming has resulted in an increase of temperatures around the world and in our oceans. It is also leading to changes such as intense storms and droughts; melting glaciers; and rising seas.
Humans must reduce greenhouse gas emissions to avoid further climate change damage. This can be done by switching from fossil fuels to renewable energy sources such as solar and wind power. We can also adopt reforestation methods or agricultural methods that allow the soil absorb more CO2 in the air. These activities will reduce atmospheric greenhouse gas concentrations and create a healthier environment that supports all life.
What is the current global climate? And how is it changing over time?
The current state of the global climate is one of unprecedented change and uncertainty. Unprecedented levels in atmospheric carbon dioxide are causing global temperatures to rise significantly. This can lead to droughts and heat waves as well changing rainfall patterns, melting Polar ice caps, ocean acidification and rising sea levels.
These changes are already having a profound impact on ecosystems around the world, causing extinctions and disruption of habitats. They are also threatening the lives and livelihoods of billions of people, particularly those in areas already facing resource scarcity and poverty.
The number of extreme weather events - such as cyclones, hurricanes, floods, and wildfires - has been steadily growing over time due to higher average surface temperatures caused by human activity. As temperatures rise, this trend will likely continue.
A rapidly changing climate has many effects. They can impact everything from food insecurity to displacement by extreme weather events to sea level rise, causing communities to relocate. Climate change is also exacerbating existing social inequalities by disproportionately affecting marginalized communities that do not possess the resources or knowledge necessary for adapting effectively.
While progress has been made in some countries in terms of reducing carbon emission or developing renewable energy programs, there has yet to be any meaningful action taken at a global scale that would allow us to address these issues effectively. We must all work together now to stop further disruptions and destruction from climate change.
What is the impact of land use change and deforestation on climate change?
The climate can be directly affected by deforestation and changes in land use. Carbon dioxide, which is the most important greenhouse gas on Earth, can't be absorbed by trees if they are removed or burned. This is why less carbon dioxide is removed when trees are cut down or burned for agricultural reasons.
Land use changes can also increase the atmospheric concentration of greenhouse gases. In addition to methane and nitrous oxide, pesticide and fertilizer use can increase when forests are converted into agricultural lands. Also, clearing can increase soils containing large amounts of carbon; these soils may be exposed to farming activities that turn them over or disturb them, which will release more carbon dioxide in the atmosphere.
The impacts of deforestation and land-use change extend beyond just increased greenhouse gas emissions; it can also have an impact on regional air quality. As an example, deforestation smoke has been shown to reduce visibility and cause respiratory illnesses such asthma and other conditions. The cumulative effects of these changes in local air quality could have an impact on global climate change. Higher temperatures can be caused by more sunlight reaching the Earth's surface due to lower aerosol particles.
The deforestation of land and the resulting changes in land-use have made a significant contribution towards increasing global greenhouse gas emission levels. These impacts have also had a negative impact on local air quality which has further contributed to climate change. If serious efforts to mitigate climate change are to be made, it is important that these practices are reduced.

How To
How to support climate-friendly policies and companies
Individuals have many options to support climate-friendly policies. This can include speaking out against non-climate-friendly businesses or politicians, voting for pro-environment candidates, writing letters or emails of encouragement to those who are already taking positive action towards the environment, and signing petitions in favor of policies that encourage and support climate-friendliness. Individuals can also immediately take more practical steps such as switching providers when possible to ones that have a better environmental record or choosing sustainable products over those with higher carbon emissions.
It is important to reduce one's carbon footprint in order to support climate-friendly companies and policies. It is possible to make simple changes such as turning off lights and unplugging devices, moving by public transport or carpooling, using eco-friendly household goods like biodegradable cleaning products and composting kitchen wastes instead of adding them to the landfills.
Investors interested in supporting climate friendly policies should research companies with lower carbon emissions before investing. Additionally, they should look into their portfolios periodically to ensure they meet the sustainability standards they have set themselves ahead of time. Investors may want to ensure that their investments in Green bonds do not finance projects with any activity which contributes more greenhouse gases into the air than they take away. Investors should be alert to opportunities where funds can be converted towards green business activities like renewable energy alternatives or other initiatives promoting sustainability, such as community-building projects based on green technologies.
