There is natural climate change and then there is man-made climate change – and the latter is where the world’s scientists have measured dramatic changes over the last decades. The world is on average around 1°C warmer now than before the industrialization.
When fossil fuels are burnt and the concentration of greenhouse gases in the atmosphere increases, we get global warming and climate change. Man-made climate change is also called anthropogenic climate change.
The likely effects of climate change include:
- Worse conditions for food production in parts of the world
- Rising seas and flooding depriving people of their land
- Increased competition over scarce resources (water and energy for example) can lead to conflict
- Animals and plants which can’t adapt to the effects of climate change will face extinction
