The Narwhal curve shows the gap between the actual progress (for the US) on renewables and what it takes to get under 2 oC. It is called Narwhal as the shape of the graph resembles the toothed whale. The term is associated with Professor Leah Stokes, who plotted the progress of the top two emitters (electricity and transportation) to become carbon-free in the US until now (about 1- 2% growth rate) to the rate that is required to meet the target of carbon-free electricity and transportation by 2035, which is more than 10%.
