How clear and simple data visualizations bring the climate crisis home

One of the most common ways to show its effects is through rising temperatures. A typical IPCC graph might show global mean temperatures increasing over the past century. These graphs are comprehensive, but they can also be difficult to interpret and often feel abstract.

A more striking alternative is the climate stripes graphic, which compresses over a century of data into a series of blue-to-red color shifts. The result is a sharp visual transition, and while the chart doesn’t include any numbers, the message is hard to miss. It also introduces a kind of binary framing: cold vs. hot, blue vs. red, normal vs. not.

Other graphics build on this idea. One New York Times graphic, for example, overlays a traditional temperature chart with color-coded shading to make recent warming more visually salient.

Separately, in a piece by Zeke Hausfather, also in the Times, the trend is broken into three color-coded segments and animated to draw attention to how warming has accelerated in the past 15 years. This kind of design encourages “step-wise” thinking, prompting viewers to interpret the warming not as slow or gradual, but as a sudden shift. That’s the same kind of perception we observed in our own study.

The same lesson applies to how we visualize the loss of Arctic sea ice. NASA’s standard line graphs show the area of sea ice declining over the past few decades. These are clear in a technical sense, but they ask viewers to interpret a slope and mentally translate that into real-world loss.

There are ways to make this loss feel more concrete. One graphic from The Economist, for example, distills the long-term decline into three snapshots: sea ice coverage in 1980, 2000, and 2019. By grouping the data this way, the charts emphasize not a gradual slope but a step-wise pattern of loss. Viewers don’t need to track exact numbers. They just need to register the shrinking boundary of Arctic ice to understand what has disappeared.

While temperature and sea-ice visuals often show large-scale, abstract trends, it’s even more important to communicate how climate change is affecting everyday life.

One culturally familiar and concrete example is the gradual disappearance of white Christmases. This phenomenon is typically shown using winter temperature or snowfall graphs, which are informative but can feel detached.

In contrast, some graphics take a more localized and personal approach—marking each year in a specific city, like Toronto or Berlin, as either a white Christmas or not.

This kind of yes-or-no framing mirrors the design of our lake-freeze study and may be more effective at conveying what’s been lost, especially when tied to familiar places.

Localizing and familiarizing climate change further, Climate Central has created several graphics showing how climate change is influencing different cultural activities across the United States. For example, one graphic shows how rising temperatures are affecting football season in different US cities.

These visuals link climate trends to specific teams and locations, making the effects of warming feel more immediate—especially for audiences that might not connect with global averages.
