"Methane has emerged as the critical greenhouse gas to be tackled this decade, and today's IPCC report affirms that," said Daphne Wysham, CEO of the NGO Methane Action, which is working to identify solutions that can rapidly reduce atmospheric methane concentrations. "Without rapid reduction in manmade methane emissions and active methane removal, we will not be able to meet our Paris Agreement targets, and Methane Action is the only NGO working on both. We are heartened to see the IPCC acknowledge the importance of our science advisors' work."
