Climate Change refers to changes in the average weather experienced over a long period. This includes temperature and rainfall patterns.
Over the years, greenhouse gases have accumulated in the atmosphere, and their warming effect is now leading to rising sea levels and the breakdown of our climate.
It is likely to mean warmer wetter winters and hotter drier summers with more extreme weather events such as greater flooding and heatwaves.
It is identified as the single greatest threat humanity has ever faced.
