Global emissions need to peak this year to stay within 1.5°C of global temperature rise since pre-industrial levels. This means that starting now, countries need to emit less greenhouse gas. Emissions also need to be cut in half by 2030 to prevent the worst effects of climate change.
For many nations, 1.5°C is a benchmark for survival. At that temperature, small island states in particular risk becoming uninhabitable due to rising sea levels, ecosystem loss, water insecurity, infrastructure damage and livelihood collapse.
