 Greenhouse gas emissions
A graph shows the deviation of the global air temperature between 1850 and 2017 from the average global air temperature from 1961 to 1990, which is taken as the baseline period. 2017 was 0.54 degrees Celsius warmer than the baseline average.
 Global surface temperature
A graph shows the number of hot days in the areal mean for 1951 to 2018. Although the trend varies greatly, the increase is clearly visible. A trend line has also been plotted on the graph which shows a significant rise.
 Hot days
A graph shows the trend for greenhouse gas emissions avoided through the use of renewables for power, heat and transport. 27.8 million tonnes of CO2 equivalents were avoided in 1990, and 177.8 million tonnes in 2017.
