Climate change is one of the most urgent issues of our time. It is an existential threat because it could make Earth completely uninhabitable for humans. Scientists have agreed that we need to limit global warming to 2°C (ideally 1.5°C), but there is currently a high chance that we will surpass 3°C. It is important to note that even the current level of climate change will exacerbate most other issues, such as hunger, poverty, and war.
