Global warming's top culprit, carbon dioxide, is helping to boost crop yields in some parts of the world. Higher levels of carbon dioxide in the atmosphere can cause plants to grow faster and produce more leaves and stems. This can lead to increased yields of agricultural crops, such as wheat, rice, and corn. However, the benefits of carbon dioxide fertilization are likely to be offset by the negative impacts of climate change, such as rising temperatures, changes in precipitation patterns, and more frequent extreme weather events.
