Planetary wellbeing

Human-caused climate change is a significant and lasting change in the Earth's climate as a result of human activity. One of the main causes is the excess release into the atmosphere of greenhouse gases such as carbon dioxide⁠ and methane, through burning fossil fuels, deforestation and agriculture. These gases trap the sun's heat in the Earth's atmosphere, creating the so-called greenhouse effect, which raises the planet's temperature. Since the beginning of the Industrial Revolution, human activity has raised the average global temperature by about 1.4°C (as of 2025)⁠.

Climate change is worrying because it has many serious consequences. For example, sea levels are rising and flooding coastal areas, extreme weather is becoming more frequent and more intense, and ecosystems are being destroyed. It also affects the global food supply and threatens biodiversity.
