The build-up of greenhouse gases, largely from industrialised nations, is raising global temperatures, melting glaciers, lifting sea levels and intensifying extreme weather. This has forced hard political questions about who is responsible for past emissions and who should bear the cost of action — a persistent fault line between developed and developing countries.

Second, depletion of the ozone layer.
