The greenhouse effect is crucial for climate change as it involves the trapping of heat in the Earth’s atmosphere by greenhouse gases, such as carbon dioxide, methane, and nitrous oxide. These gases allow sunlight to enter but hinder the escape of infrared radiation, resulting in a gradual increase in global temperatures. The enhanced greenhouse effect, driven by human activities like fossil fuel burning and deforestation, leads to significant changes in climate patterns, causing severe weather events, rising sea levels, and disruptions in ecosystems, all of which underscore the urgency for climate action.
