Climate Change in Numbers

The Climate Action Unit is developing metrics that communicate clearly what is happening with climate change right now


We are currently developing three new metrics which help people understand how human activities result in climate change, and how this links to the weather we experience.

The project uses a 'design-led' approach. This means we're starting with communications and design principles, rather than basing the metrics on what data is already availabile. We're also taking lessons learned from the COVID-19 crisis about how communicators used metrics like the R-number.

Current activities

In November 2022, we completed the design sprint to visualise the three metrics conceived in the first part of the project. We then conducted a testing phase until the start of 2023 with a core group of end-users. 

From January 2023 onwards, we worked with design studio Accurat to refine the prototype metrics, including their design and the online platform on which they will operate. We connected the metrics up to the latest data sets in March 2023, and are now planning a series of events to launch the metrics with journalists, science communicators, policymakers, the general public and other end-users.

Our series of launch events will be announced in April 2023.
