This study aims to enhance government leadership in responding to the climate crisis by strengthening the application of new media communication. In the era of new media, we can get climate information quickly and easily, which brings new opportunities and challenges for the government to deal with the climate crisis. There are many deficiencies in the government's new media services in response to the climate crisis. The content and ways of communication are relatively simple, and the ability to interact with the public is insufficient; failure to establish cooperation mechanisms with multiple organizations; the ability and quality of the government to make use of new media to publicize the climate crisis should be improved; government needs to improve its level of political inquiry and handling through new media. Therefore, we suggest that the government should make reasonable use of new media to increase the publicity of the climate crisis, leverage external forces to diversify the response to the climate crisis, establish a new media public communication platform, and improve the awareness and ability of government personnel to use new media.
