During a high school debate on global warming, explain that the scientific community at large warns of severe negative consequences to come if humans do not take action to stop climate change from occurring. Cite reputable organizations, such as the Natural Resources Defense Council and Union of Concerned Scientists, to support this claim. Describe how the buildup of carbon dioxide in the atmosphere contributes to increased average temperatures by trapping heat from the sun.
A complete debate on global warming should touch upon the dangers that climate change poses to the planet and its inhabitants. As heat levels rise, humans become at a greater risk for heat-related sicknesses and death, according to the NRDC. Increasing global temperatures also cause the sea levels to rise, making coastal areas more prone to flooding, notes the Union of Concerned Scientists. Additionally, an increase in air pollution poses health risks to humans and animals, such as by increasing the concentrations of allergens in the air. Wildfire season grows longer, and wildfires occur more frequently with climate change, as well.
It is also important to explain what steps people must take to curb global warming. Stopping deforestation is one of the best ways to reduce carbon dioxide emissions, according to the Union of Concerned Scientists. Depending less on coal and other fossil fuels for energy also helps reduce emissions.
