MODELLING SEA LEVEL CHANGES

STUDENT BOOKLET

MODELLING SEA LEVEL CHANGES BACKGROUND INFORMATION

Over the past 20 years, sea level rise has accelerated due to climate change. This rise in sea levels has affected vulnerable populations in small island nations. Scientists around the world have used techniques such as satellite tracking to measure changes in the oceans – and they have found that the global average of sea level rise per year is 4 mm.

Researchers believe humans are to blame for this rise in sea levels. Industrial activities have generated pollution and carbon dioxide (CO2) – a colourless and odourless gas that is produced by burning carbon and other organic compounds. CO2 is considered a greenhouse gas (climatekids.nasa.gov/greenhouse-effect), which means it absorbs heat, working almost like a blanket that keeps the planet toastier than it should be.
