In 2005, in Gleneagles, Scotland, G8 nations committed to “act with resolve and urgency” to reduce greenhouse gas emissions. Leaders also committed to “work with developing countries on building capacity to help them improve their resilience and integrate adaptation goals into sustainable development strategies.” 1 Five years later, climate change is dangerously near irreversible tipping points, and the intensifying impacts of climate change are threatening the lives of vulnerable people across the globe. Meaningful action by G8 and G20 leaders has never been more urgent.
