The planet is facing a crisis. Temperatures continue to rise, bringing extreme weather, exacerbating food shortages, and leading to the extinction of some species. Scientists have repeatedly warned that the effects of climate change are becoming irreversible.

In this week's Arena, we debate these issues with renowned climate scientist James Hansen, climate activist and cofounder of the Sunrise movement, Varshini Prakash and Amanda Mukwashi, CEO of the global NGO Christian Aid.
