Explain that increased greenhouse gas concentrations are linked to global climate change.

Increased concentrations of greenhouse gases, such as carbon dioxide and methane, trap more infrared radiation emitted from the Earth's surface, leading to a rise in global temperatures. This phenomenon, known as the greenhouse effect, is a significant driver of global climate change. As these gases accumulate in the atmosphere, they enhance the natural greenhouse effect, resulting in alterations to weather patterns, rising sea levels, and more frequent extreme weather events. Understanding this link is crucial for addressing climate change and implementing effective mitigation strategies.
