Peatlands are like time capsules that hold clues about how the environment has changed over thousands of years. By studying the layers of peat, scientists can learn about past climates, how peatlands have evolved, and how they store carbon. Recent advances in dating methods and research techniques have renewed interest in using peatlands as records of climate change. Climate has influenced how much carbon peatlands store and the health of these ecosystems. By studying peatlands, researchers can better understand how human activities impact these important habitats and how to protect them. Peatlands offer a diverse range of information that can help answer many research questions and should be studied more by scientists.
