Drivers, changes and impacts

What does a rising temperature mean for our planet? Find out what the drivers, changes and impacts are of a global rise in temperature.
Drivers Changes And Impacts

As Nishtha Singh explained earlier, we know from temperature measurements that global average temperatures have already increased by around 1 degree Celsius. Climate models suggest that warming will continue if we don’t change our behaviour.

Why does this matter? Is 1°C or 2°C or even 5°C really such a big deal? Let’s find out! What does a rising temperature mean for our planet?

Review the diagram below. The centre shows what is driving climate change, the inner ring shows examples of changes that are happening to the climate system, and the outer ring shows examples of the impacts that those changes are causing. You can read more about the drivers, changes and impacts below.

Drivers of climate change

Human activity, such as the burning of fossil fuels and deforestation, lead to an increase in greenhouse gases in the atmosphere. Remember the Tetris cubes that were piling up? This leads to a rise in global temperatures. The higher the global temperatures, the more changes are triggered in the global climate system.

Changes to the climate system

These changes include: the melting of sea ice, ocean acidification, increase in sea levels, changes in ocean circulation, as well as more frequent and more intense extreme weather events. These changes to the climate will have wide-spread impacts on natural and socio-economic systems.


Changes such as rising sea levels can lead to flooding of coastal regions, damage to infrastructure (like bridges, roads and power grids), climate migrants, and a risk to drinking water supply. Higher temperatures on land can lead to: the introduction of new pests that can affect human and crop health, increased heat stress, and food insecurity from crop failures.
