Climate change videos discuss a wide range of topics such as how climate change is affecting our environment and what we can do about it. These videos can be used to educate and engage the public. Some provide a good introduction to key issues while others show how to take action to reduce emissions.
The relationship between climate change, greenhouse gas emissions and other factors is one of the most important aspects to understand. A graph shows the relative increase of CO2 emissions from the largest emitters in each country over the past 150 years. This shows that greenhouse gases have been tracking closely with temperature, which means we have been gradually warming up for more than three decades now.
The effects of climate change have already had devastating impacts on the environment. These include melting of the ice sheets in Greenland and Antarctica, increasing sea level rise, and shrinking capacity of the oceans. This could also increase fire risk, particularly in 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 has this series. The episodes feature interviews featuring scientists and experts. They also examine the science behind climate change.
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. While many of these videos are protected by copyright, philanthropists may purchase the rights.
John Holdren is back to discuss the tradeoffs involved in geoengineering. He is the director of Woods Hole Oceanographic Institute and also spoke about the forthcoming Arctic Ocean albedo flip.
There are many other climate change videos that can be found on the Internet. ETV South Carolina has a great video called "Global Warming - The Signs and the Science". This documentary provides a comprehensive overview of the causes, effects, and solutions to global heating.
Another great documentary is 'What's 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. Also, the rate of melting from the Antarctic ice sheet has accelerated over the past five years.
As a consequence, the oceans are becoming acidicer and have a decreasing capacity to absorb carbon. Additionally, the oceans will rise as much as 1.5 inches per ten years by 2050. At the same time, flooding is a growing problem in coastal areas and islands.
FAQ
What are the impact of deforestation and land use change on climate change?
Deforestation, land use change and other factors have an immediate and direct impact on climate. Carbon dioxide, which is the most important greenhouse gas on Earth, can't be absorbed by trees if they are removed or burned. Carbon dioxide is therefore less removed from the atmosphere when trees are deforested or burned for agricultural purposes.
Changes in land usage can also cause more greenhouse gasses to be released into the atmosphere. In addition to methane and nitrous oxide, pesticide and fertilizer use can increase when forests are converted into agricultural lands. Clearance can increase exposure of soils that have large amounts stored carbon. These soils release carbon dioxide when they are turned over or disturbed through farming activities.
Deforestation and land-use changes can have a significant impact on regional air quality. For instance, smoke from burning events associated with deforestation has been linked to decreased visibility as well as health concerns such as asthma and other respiratory ailments. 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.
In conclusion, both deforestation (and land-use) change have been a major contributor to rising levels of global greenhouse gases emissions. Additionally, they have had negative effects on local airquality that has contributed further to climate changes. If serious efforts to mitigate climate change are to be made, it is important that these practices are reduced.
What are the roles of greenhouse gases in climate changes?
Greenhouse gasses are key to climate change. They act as an invisible layer around the Earth trapping infrared radiation. This warms the atmosphere. Without them, our planet would be much cooler than it is now.
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.
The most prevalent greenhouse gas is carbon dioxide, which is released from fossil fuels, such as oil, gas, and coal. Other major contributors to climate changes include methane, nitrous oxide and fluorinated gases (F-gases).
Human activities have caused a significant increase in greenhouse gas concentrations since preindustrial times. Global warming has caused an increase in temperature all around the globe, and in our oceans. It is also causing drastic changes, such as increased storms, droughts, melting glaciers and rising ocean levels.
To prevent further climate change-related damage, humanity must reduce its greenhouse gas emissions by moving away from fossil fuels and towards renewable energy sources like wind or solar power. We can also take measures such as reforestation or adopting agricultural methods that allow the soil to absorb more CO2 from the air. These activities will lower the atmospheric concentrations of greenhouse gasses and make the Earth a more healthy place for all life.
How does climate change politics impact global efforts?
Climate change has become a highly politicized topic that has caused great divisions among governments, nations, and individuals. The political stances taken by different actors will impact the implementation measures to combat climate changes. It has become difficult to find consensus on global efforts to tackle this pressing environmental crisis.
The vast majority of scientific opinion agrees that human-generated climate change is real and requires urgent action. These politics often hamper global cooperation needed to achieve effective progress in implementing sustainable energy practices.
Most governments are eager to protect their business interests and enforce rules that will limit business activity as much as possible. This is often in conflict with the regulations experts recommend to combat climate change. Without strong commitments of all participating countries, and international action on a large scale, it becomes difficult for any state or group or states to effectively address climate-change legislation.
It is difficult to reach a consensus about how to address climate change because of differences in power dynamics between countries. Countries with more economic power often appoint their own representatives to represent them on international bodies responsible for negotiations over the environment - this can lead to lopsided discussions of those countries' perceived interests versus the collective interest of all involved parties. The potential side effects of radical change like geoengineering, have been extensively discussed at both the national level and internationally.
The grassroots movements also have struggled against powerful enemies, such as corporate ownerships and well funded lobbyists who want to maintain politically favorable positions in their industries. This includes funding research into alternative forms energy production and enforcing renewable technology mandates. It is important that individual governments are clear about the possible rewards and outcomes if they intend to actively pursue valid progress on this matter and not seek public favor through short-term gains and spectacles.
Properly distributing resources allocated towards any intervention program while being mindful of political divisions between nations will be critical if any coordinated effort aimed at mitigating our current environmental crisis is going successfully to come to fruition.
What is the impact of climate change on biodiversity and ecosystems?
Climate change can have a variety of impacts on biodiversity, ecosystems, and the environment. Rising temperatures, changes in extreme weather events and sea levels, as well as increased acidity in the ocean are just some of the issues affecting wildlife and ecosystems today.
These changes can result in shifts of habitat areas, disrupting food chains or affecting population numbers or distributions. With potentially devastating consequences for biodiversity, ecosystems and their functioning, these shifts in climate conditions could cause significant impacts. Changes in the hydrological cycle can also affect water availability for aquatic species.
Moreover, changes to climate result in rising temperatures and more frequent extremes such as droughts and floods which puts more stress on already fragile systems such as coral reefs or tropical rainforests. Climate change could lead to the extermination of up to 30% of animal species by 2050. This would cause further ecological community losses.
Climate change poses a significant threat to biodiversity and human societies, as well as to ecosystems that provide food, water, timber, or other services. It is essential to mitigate its effects at all levels. Future damages must be avoided by careful management.
How are extreme weather events related to climate change?
Global warming has directly affected extreme weather phenomena such as heatwaves. Global warming has caused an increase in atmospheric temperatures. This has had an impact on different weather phenomena worldwide.
Climate scientists claim that the frequency of extreme weather related disasters has more then doubled since 1980. Sea levels rise as a result of changing wind patterns and ocean temperatures. This impacts the normal distribution of storms or hurricanes in different areas across the globe.
Warm water was pushed towards South America by the 2015 El Nino event. This caused rising temperatures to alarming levels. Heavy rains also caused flooding in Peru and Bolivia, causing displacement and property damage. Many places, including Antarctica had their highest-ever temperatures. This suggests a connection between global warming trends or the occurrence or frequency in extreme weather events.
Another example is Hurricane Irma in 2017. It caused $50 billion economic loss to Florida and other states, as well as Puerto Rico and Cuba. This is yet another proof that climate change is responsible.
The Intergovernmental Panel on Climate Change (IPCC) concluded that human activities are increasing the severity of current climate change which naturally leads to more frequent, severe, and intense natural disasters globally hence bringing forth strong evidence regarding humans' relation to extreme weather events occurring at frequent intervals around us all.
What can be done to ensure a sustainable future, given the climate change challenges?
Sustainability refers to the ability to satisfy current needs while not compromising future generations' ability to do so. Climate change is presenting new challenges. We need to take immediate action to end our dependence on finite resources.
It is crucial that we reexamine our consumption and production patterns, as well our dependence on fossil fuels, in order to move towards a sustainable future. We need to find new technologies, renewable energy sources, and systems that can reduce harmful emissions and still meet our daily needs.
Furthermore, it is crucial to take a holistic approach to sustainability. This means taking into account all aspects of production, from the materials used, waste management, and reuse strategies, to energy utilization in transportation and industry. There are many options available, including the use of renewable energies like solar, wind and hydropower, improved waste management systems, increased efficiency in agriculture, improved transport networks, green building regulations, and sustainable urban planning.
For us to achieve our goal, we must make behavioral changes across all segments of society. Education programs will be needed to support individuals in understanding climate change and how they can positively contribute towards a sustainable world.
We can only make significant progress in creating sustainable environments for the future by working together with industry leaders, citizens, and governments.

How To
How to reduce your carbon footprint and fight climate change
There are many things you can do to help reduce your carbon footprint, and fight climate change. First, you can reduce your energy consumption by purchasing energy-efficient appliances, lighting and insulation. You can also reduce energy consumption by turning down your thermostat during winter and summer, unplugging electronics, using public transportation, walking instead of driving, and switching off lights when they are not in use.
Second, try to recycle and compost all food scraps. It will help prevent them from ending up in landfills that emit methane gas. Third, plant trees around your home for shade and natural cooling since vegetation absorbs carbon dioxide from the air. The last thing you should do is to look for products that have minimal packaging and sustainable labels, such organic cotton or FSC certified wood. This means the product has been sustainably managed over time in order to maintain forest health.
You can help reduce your personal emissions by supporting organizations such as Emissions Reduction Alberta, Climate Change Solutions; The Pembina Institute and The Nature Conservancy Canada. These organizations work to lower emissions through clean energy investments. They also support international initiatives such ICLEI – Local Governments for Sustainability's Urban Sustainability Strategies program.
