Let the Earth Warm Up at Most 1.5℃: The Application of Information Visualization Design in Climate Change Communication

This study proposes and implements an exhibition design project on the theme of “Let the Earth Warm Up at Most 1.5℃”, which is centered on the issue of global climate change. By integrating visualization design, spatial display and science communication, the project aims to present the global warming trend triggered by greenhouse gas emissions and its multiple impacts on the ecosystem in a visual and tangible way. The exhibition is based on the HadCRUT Global Surface Temperature Dataset (1860-2020), which is a multi-dimensional graphic based on scientific evidence, reflecting the trend of global average annual temperature change since the Industrial Revolution.The design covers a number of ecological tipping points in the context of climate warming, such as the melting of the Greenland ice cap, the degradation of the Amazon rainforest, the reduction of Arctic sea ice and the demise of coral reefs, etc. Through screen installations, multimedia interactions and information on display panels, it simulates the temperature rise scenarios and their chain of impacts on biodiversity. Among them, the “sensible” design is reflected in the integration of visual, auditory and tactile dimensions, such as the visualization interface, real-time feedback temperature measurement paper material and temperature rise simulation device, etc., so that the audience can perceive the real consequences of climate change in an immersive environment.At the same time, the exhibition extends to supporting design elements such as exhibition tickets, cultural and creative packaging, and the use of eco-friendly materials to stimulate audience engagement and emotional resonance.“Public Participation” is reflected through sustainable education modules and interactive feedback mechanisms, such as “Future Commitment Card” and “I will do something to reduce carbon emissions for the Earth”, which will guide the audience to the project's design logic is based on the concept of “Climate Action”.The design logic of this project is based on the path of “scientific fact - visual interpretation - public participation”, exploring the role of design in environmental communication and climate action. Through the construction of an interactive environmental education field, the project promotes the audience's understanding and emotional resonance of climate change issues, and highlights the potential and responsibility of design as a communication medium in social sustainability issues.
