资源简介：
The daily climate change news indices for China from 2010 to 2025 are provided.
Initially, based on nearly 4.9 million news articles published by nine Chinese newspapers (People's Daily, Guangming Daily, Xinhua Daily Telegraph, China News Service, Science and Technology Daily, Science Times, China Energy News, China Environment News, and Global Times) from January 2010 to November 2022, the indices were constructed using the Latent Dirichlet Allocation (LDA) model, encompassing five distinct themes: natural disasters, climate governance, energy transition, climate cooperation, and climate communication.
Subsequently, the indices were updated to 2025 utilizing a naive Bayes model.
