What is identified as the major cause of global warming that should be included in an informational session?

The primary cause of global warming is identified as greenhouse gas emissions. These gases, such as carbon dioxide, methane, and nitrous oxide, trap heat in the Earth's atmosphere, leading to a rise in global temperatures. The combustion of fossil fuels for energy, widespread industrial activities, and agricultural practices significantly increase the concentration of these gases in the atmosphere. By including this topic in an informational session, participants can understand not just the phenomenon of global warming itself but also the underlying human activities contributing to it.

While deforestation plays a significant role in climate change by reducing the planet's capacity to absorb carbon dioxide, it is a part of the broader scenario of greenhouse gas emissions. Similarly, while methane emissions from landfills contribute to the greenhouse gas effect, they represent a specific source rather than the overarching problem. Ozone layer depletion is an important environmental issue, but it concerns the ozone layer specifically and does not directly relate to long-term global temperature increases in the same way that greenhouse gas emissions do. Emphasizing greenhouse gas emissions in discussions about global warming provides a clearer understanding of the root cause and a foundation for effective climate action.
