An inconvenient truth? What does al gore arthur of an inconvenient truth demonstrate about the level of atmosphere carbon dioxide levels
In "An Inconvenient Truth," Al Gore demonstrates that the level of atmospheric carbon dioxide (CO2) has been increasing at an alarming rate. He presents scientific data and evidence from various sources to show that human activities, particularly the burning of fossil fuels, have led to a significant rise in CO2 levels over the past century.
Gore highlights the correlation between CO2 levels and global temperature, emphasizing that as CO2 concentrations increase, so does the Earth's average temperature. He emphasizes that this rise in temperature is causing detrimental effects on the planet, such as sea-level rise, extreme weather events, and the melting of polar ice caps.
Gore demonstrates that the current level of atmospheric CO2 is higher than it has been in the past 650,000 years, based on ice core data. He argues that this rapid increase in CO2 is primarily driven by human activities and that it contributes to the phenomenon of global warming and climate change.
Overall, Gore's "An Inconvenient Truth" highlights the alarming levels of atmospheric carbon dioxide that have been caused by human actions and stresses the urgent need to reduce greenhouse gas emissions to mitigate the impacts of climate change.
In the documentary film "An Inconvenient Truth" authored by Al Gore, the former Vice President of the United States, he demonstrates the rise in atmospheric carbon dioxide (CO2) levels and its consequences on global warming and climate change. Here is a step-by-step breakdown of what Gore demonstrates regarding the level of atmospheric carbon dioxide:
1. Explanation of the Greenhouse Effect: Gore starts by explaining how the Earth's atmosphere naturally acts as a "greenhouse," trapping heat from the sun and maintaining a stable climate. He emphasizes that certain gases, including carbon dioxide, methane, and nitrous oxide, are essential for this effect.
2. Historical Carbon Dioxide Levels: Gore presents historical data showing variations in carbon dioxide levels throughout Earth's history. He outlines how these levels have fluctuated but remained within a relatively stable range for the past 10,000 years.
3. Dramatic Increase in CO2 Levels: Gore demonstrates that since the Industrial Revolution, human activities, particularly the burning of fossil fuels, have significantly contributed to the release of carbon dioxide into the atmosphere. He presents various charts and graphs indicating a steep rise in CO2 levels over the past century.
4. Relationship with Temperature: Gore further explains the correlation between atmospheric carbon dioxide and global temperature. He shows that throughout history, increased levels of CO2 have corresponded with higher temperatures. He includes evidence from ice core samples and other scientific studies.
5. Consequences of Rising CO2 Levels: Gore outlines the potential consequences of increased carbon dioxide levels, such as melting glaciers, rising sea levels, extreme weather events, and the disruption of ecosystems. He highlights the threat to human health, food security, and national security.
6. Action and Solutions: Finally, Gore discusses the urgency of addressing climate change and presents possible solutions, including transitioning to renewable energy sources, improving energy efficiency, and adopting policies to reduce greenhouse gas emissions.
Overall, "An Inconvenient Truth" demonstrates that carbon dioxide levels in the atmosphere have significantly increased due to human activities, leading to global warming and climate change. Gore's purpose is to raise awareness about the issue and advocate for actions to mitigate the impacts of rising CO2 levels.
