How Climate Scientists Predict the Future

The video explores the history and future of Earth's climate, highlighting the evolution of climate models from the 1940s to today. It discusses how these models have improved in accuracy and detail, allowing scientists to predict future climate changes and their impacts. Despite advancements, challenges remain in perfecting predictions, especially for sea-level rise and regional effects. The video emphasizes the importance of understanding climate change to mitigate its consequences.

What is the primary method used to predict future climate changes?
