What is Climate Change?

Introduces the idea of climate change, highlighting the difference between weather and climate, and the history of natural climate change versus man-made climate change. Climate change is arguably the greatest challenge of our time. Human activity has already warmed the planet by one degree Celsius relative to pre-industrial times, and we are feeling the effects through record heat waves, droughts, wildfires and flooding. If we continue to burn fossil fuels at the current rate, the planet will reach two degrees of warming by 2050—the threshold that many scientists have identified as a dangerous tipping point. What is the science behind these projections?
