Man-made climate change is one of the biggest threats to the world, and climate change poses an increasing threat to the stability of Earth's systems. The effects are already being seen through receding glaciers, ocean acidification and an increase in extreme weather such as hurricanes, floods, and droughts. We must work to find solutions to climate change. If we want to protect our planet from dangerous and unprecedented change, first, we must understand the science behind climate change and teach it to people.
