The science is clear. We must prevent the global temperature from rising by more than 1.5°C or risk catastrophic impacts for people and nature. At the UN COP26 climate conference, there were signs that world leaders are moving in the right direction after agreeing to positive measures, including the phasing out of fossil fuel subsidies and reducing the use of coal. But, with the world still on track for warming above 2°C, countries must do so much more. Together, we must call on leaders to set stronger targets for climate action, recognize the valuable role that nature-based solutions can play, finance the work needed to build a safer future, and deliver a 50% cut in greenhouse gas emissions by 2030.
