Le Bourget, Paris — Momentum continues to build here for a landmark agreement to combat climate change. More than 170 countries have already submitted plans for climate steps they will take, which pave the way for a deal. Remaining issues include mechanisms for transparency that would ensure nations live up to their commitments, how much money will be available to help struggling nations adapt to climate change or deal with loss and damage from extreme weather, and whether commitments will be revisited and made more ambitious in the future. Yet hopes are high. As U.S. Secretary of State John Kerry noted at an event today: "I am so hopeful that Paris will be a truly historic moment."
