As the chapters of IPCC Sixth Assessment Report were released over the course of last year, it was clear that the damage from climate change is affecting us sooner and on a greater scale than we knew. Today’s findings in the IPCC Synthesis Report for its Sixth Assessment, which draws from previous released material, shows how close we are to losing the window in which we can effectively limit warming to 1.5°C, a critical benchmark in our fight against climate change. While the narrow window to limit warming to 1.5°C has not yet closed, it is growing ever narrower. 

Fortunately, the report also provides a roadmap for us to make a rapid transition with accelerated actions from nations, states, cities, businesses, and civil society. Today’s findings reinforce many of the policy solutions outlined in An All-In Path to 2030: The Beyond 50 Scenario, America Is All In’s analysis that shows how an all-of-society climate strategy can enable the United States to meet its 2030 climate target. 

Following the release of today’s report, America Is All In Co-Chairs issued the following statements: 

Michael R. Bloomberg, UN Secretary-General’s Special Envoy on Climate Ambition and Solutions and founder of Bloomberg LP and Bloomberg Philanthropies, said: "The latest IPCC report makes clear that while the battle against climate change is still winnable, time is running short. Bloomberg Philanthropies is working to help cities around the world take ambitious steps to cut emissions, but reaching our climate goals will take all of us—from local and state leaders, businesses, and national governments—going all in and coming together to find ways to do more, faster.” 

Washington Governor Jay Inslee said: “We don’t have time to agonize or despair. We must focus on mobilizing every part of our economy in the net-zero transition. State-level leadership in the United States is critical to the implementation of international and national policies. States must seize that leadership role now to make the most of historic climate investments such as the Inflation Reduction Act, while continuing the push to go even further, faster.” 

Charlotte Mayor Vi Lyles said: “This IPCC report clearly shows the widespread disruption that climate change is causing to ecosystems and livelihoods around the globe. It also outlines that when cities reduce their overall emissions, there are significant, cascading benefits that extend beyond city boundaries. By increasing investments in our facilities, infrastructure and transit, we have the opportunity to change direction and move our region toward a robust, sustainable economy powered by clean energy.”   

In addition, Nathan Hultman, Director of the Center for Global Sustainability at the University of Maryland and author of the An All-In Path to 2030: The Beyond 50 Scenario study, said: “In 2021, the U.S. set an ambitious climate target to achieve 50-52% emissions reductions by 2030. But today’s report is clear: we need to do more. And we can do more with additional actions from federal, state, city, and local governments. Our analysis shows that an all-of-society strategy that combines the transformational steps in recent federal legislation with federal regulatory actions, plus expanded leadership from states, cities, businesses, and others can get us beyond our goal.”
