The IPCC has released a new climate report, updating and synthesizing the findings from a series of previous reports. But what exactly is the IPCC? What do all these reports mean? Is our situation as grim as some of the news headlines make it sound?
We’ve prepared this guide to help you understand what these climate reports are, what their findings mean for our world and what we can do.
IPCC stands for Intergovernmental Panel on Climate Change. The IPCC is the scientific group assembled by the United Nations to monitor and assess all global science related to climate change. Every IPCC report focuses on different aspects of climate change.
This latest report is the IPCC’s 6 th Synthesis report. It updates and compiles in one report findings from all the reports in the IPCC’s sixth assessment cycle, which covered the latest climate science, the threats we’re already facing today from climate change, and what we can do to limit further temperature rises and the dangers that poses for the whole planet.
There is some good news in this synthesis report. There have been promising developments in low-carbon technologies. Countries are making more ambitious national commitments to reduce their emissions and doing more to help communities adapt to the effects of climate change. And we’re seeing more funding committed for all of this work.
The problem is it’s still not enough. Even if every country in the world delivers on its current climate pledges, that’s probably not enough to keep global warming to 1.5°C above pre-industrial levels—a threshold scientists believe is necessary to avoid the worst impacts of climate change.
Current adaptation efforts, too, are scattered and leave behind some of the most vulnerable communities. And if the planet gets much warmer, we may see irreversible changes to some ecosystems around the world, which would be catastrophic for the people and wildlife that depend on them.

Yes. Climate change is here today, reshaping our world in ways big and small—but that doesn’t mean our future is predetermined. Every fraction of a degree of warming makes a big difference in how powerful the effects of climate change will be, including the frequency and intensity of heatwaves, storms, floods and droughts. That means every action we take to limit further warming makes a big difference, especially for vulnerable communities around the world.
We need bolder global climate commitments, and we need them fast so we can transition to clean energy and reach “net zero” emissions as soon possible. And as the IPCC's reports shows, we’ll not only need to cut out emissions—we’ll have to remove some of the carbon that’s already in the atmosphere. Fortunately, nature created a powerful technology that does just that: photosynthesis. Plants naturally absorb carbon from the air and store it in their roots and in the soil.
In addition to phasing out fossil fuels, we also need to protect the natural habitats around the world that store billions of tons of this “living carbon.” We can also help by changing the way we manage working lands like farms and timber forests so they retain more carbon, and restore natural habitats on lands that have been cleared or degraded.
A global challenge like climate change requires global solutions. It will require movement-building and on-the-ground action, as well as new national policies and economic transformations. Here’s a few things that communities, governments, and business can do.
