Beyond the bad omens, COP27 also opens with some "positive" signs. Never before has the world been so convinced that climate action must be a top priority.
Furthermore, recent studies on the impact of action against climate change also urge us not to despair. Only a decade ago, before the Paris Agreement, the most pessimistic models saw the world warming to a likely untenable +4 to 5 degrees (relative to the pre-industrial era). COP26 ended with far-from-sufficient global commitments to meet the goals of the Paris Agreement, creating a huge credibility gap between long-term promises and short-term implementation. However, if all commitments were met today, the world would be on a 2.4 to 2.8-degree warming trajectory.
