BBC has created several data visualizations illustrating how much warmer the Earth will be by 2100. Charts show that even under best-case scenarios, in which climate policies severely limit emissions, major cities such as New York and London will experience July temperatures that are roughly four degrees warmer (2.2 °C and 2.1 °C, respectively) on average in 2100 compared to 1900. Under a worst-case scenario, the average temperature in July in London could increase 10 degrees (5.8 °C) between 1900 and 2100. The visualizations also show that the Arctic is melting twice as fast as the rest of the Earth.
