This is based on data from https://www.globalwarmingindex.org

  1. Watch the clock to see how long it takes for the temperature to rise by 0.000 000 01ºC. Use this to to work out how long it will take, in seconds, for the temperature to rise by 0.01 ºC. What is this in days?
  2. Assuming the temperature rise continues at the current rate, in roughly how many years will the human-induced warming reach +1.5 ºC?
