Scientists are deeply concerned about rising concentrations of atmospheric greenhouse gases, such as carbon dioxide, and their potential long-term impacts on global biodiversity.
Figure 1 shows the concentration of atmospheric carbon dioxide (CO2\text{CO}_2CO2) in parts per million (ppm) recorded between 2000 and 2024.
a.[4]
Describe two patterns shown in Figure 1. Use data from Figure 1 in your answer.
b.[2]
Give two human activities that increase the concentration of carbon dioxide in the atmosphere.
c.[4]
The trend shown in Figure 1 may continue for many years. Explain what effect the rising concentration of greenhouse gases like carbon dioxide could have on living organisms.
