It’s easy to feel pessimistic when scientists around the world are warning that climate change has advanced so far, it’s now inevitable that societies will either transform themselves or be transformed. But as two of the authors of a recent international climate report, we also see reason for optimism.

The latest reports from the Intergovernmental Panel on Climate Change, including the synthesis report released March 20, 2023, discuss changes ahead, but they also describe how existing solutions can reduce greenhouse gas emissions and help people adjust to impacts of climate change that can’t be avoided.

The problem is that these solutions aren’t being deployed fast enough. In addition to pushback from industries, people’s fear of change has helped maintain the status quo.

To slow climate change and adapt to the damage already underway, the world will have to shift how it generates and uses energy, transports people and goods, designs buildings and grows food. That starts with embracing innovation and change.

From the industrial revolution to the rise of social media, societies have undergone fundamental changes in how people live and understand their place in the world.

Some transformations are widely regarded as bad, including many of those connected to climate change. For example, about half the world’s coral reef ecosystems have died because of increasing heat and acidity in the oceans. Island nations like Kiribati and coastal communities, including in Louisiana and Alaska, are losing land into rising seas.

Other transformations have had both good and bad effects. The industrial revolution vastly raised standards of living for many people, but it spawned inequality, social disruption and environmental destruction.

People often resist transformation because their fear of losing what they have is more powerful than knowing they might gain something better. Wanting to retain things as they are – known as status quo bias – explains all sorts of individual decisions, from sticking with incumbent politicians to not enrolling in retirement or health plans even when the alternatives may be rationally better.

This effect may be even more pronounced for larger changes. In the past, delaying inevitable change has led to transformations that are unnecessarily harsh, such as the collapse of some 13th-century civilizations in what is now the U.S. Southwest. As more people experience the harms of climate change firsthand, they may begin to realize that transformation is inevitable and embrace new solutions.

The IPCC reports make clear that the future inevitably involves more and larger climate-related transformations. The question is what the mix of good and bad will be in those transformations.
