I have been trying to understand the history of international climate agreements and I keep hearing about COP21 in Paris being this huge breakthrough, but I am less clear on what actually happened at COP22 the following year in Marrakech. Was it just a follow up meeting or did they actually make significant progress on implementing the Paris goals? I am particularly interested in how developing countries were supported and whether the funding pledges materialised into real action. I have found some general summaries but nothing that gives me a clear picture of the specific outcomes and why this conference mattered beyond just being another annual meeting. Does anyone have a good resource that explains the significance of COP22 in plain language?
