The main threat to polar bears is climate change because it melts sea ice. Climate change, is the result of greenhouse gases. Greenhouse gases (GHGs) in the atmosphere act like a blanket that keeps the earth warm. Over the past 200 years, humans have greatly increased the level of GHGs in the atmosphere by burning fossil fuels like oil and coal. This is like throwing on a second blanket, causing temperatures to rise and melting sea ice.
