The chances of keeping global temperature rise below 1.5C, the toughest goal of the Paris Agreement, are increasingly slim. “Well below 2C” is a stretch.


Yet there has been little discussion at an international level on how to handle “overshoot” of those goals. A high-powered commission due to launch in May aims to break the silence.


Climate diplomats are finalising a 15-strong lineup of former presidents, ministers and representatives of international organisations to explore options for deep adaptation, carbon dioxide removal (CDR) and geoengineering, Climate Home News can reveal.


The Climate Overshoot Commission will address sensitive questions around the ethics and feasibility of potential ways to reverse warming that are problematic or unproven at large scale.


“The primary strategy to combat climate change should remain reducing greenhouse gas emissions, but it has also become necessary to explore additional strategies,” Jesse Reynolds, executive secretary of the commission, told Climate Home.


France’s Pascal Lamy, director general of the World Trade Organisation between 2005 and 2013, has been appointed as chair. He is president of the Paris Peace Forum, which will host the commission.
