What will it take for countries to keep their climate promises?

World leaders are gathering in Glasgow for a global climate summit to agree on how to further limit the threat of global warming. Experts say the conference, known as COP26, could be the last chance for governments to agree on a way to cut global emissions in half by 2030. It’s also an opportunity to assess how well they have been doing with previous targets to prevent average global temperatures from rising beyond 1.5 degrees Celsius, agreed at a big climate meeting in Paris in 2015. According to the Climate Action Tracker, The Gambia is thought to be one of the only countries with plans in line with 1.5 degrees. What further commitments will leaders from the rest of the world arrive with at COP26 and what will it take for countries to keep those climate promises?
