Global Climate Change

Increasing the average global temperature is a significant reason for global climate change. The potential consequences are severe and wide-ranging:

Melting of polar ice caps

Melting of polar ice caps

  • The melting of polar ice caps would cause:
  • Sea levels to rise, leading to flooding and erosion of our coastlines.
  • Some species to be less successful hunters (e.g. the polar bear).
Meteorological events

Meteorological events

  • Extreme meteorological events, such as storms, heatwaves and droughts, could increase in frequency and intensity.
Changes in water availability

Changes in water availability

  • Changes in water availability could affect how species are distributed.
Changes in precipitation

Changes in precipitation

  • The quantity, timing and distribution of precipitation could change. This would result in some regions receiving much less or much more rainfall than they previously did.
Food shortages

Food shortages

  • A combination of some or all of these factors could hinder a region’s ability to produce food. This could lead to potential famines.

Test yourself on Climate Change

  • How could a combination of climate change factors affect a region's ability to produce food?

  • What is a direct result of melting polar ice caps, rather than a change in precipitation patterns?

  • Why would the melting of polar ice caps lead to the flooding and erosion of coastal regions?

  • How could global climate change affect extreme weather events such as storms, heatwaves and droughts?

  • How could changes in water availability caused by climate change affect wildlife?
