Abstract:In 2022, The United Nations' Intergovernmental Panel on Climate Change (IPCC) released the Sixth Assessment Report (AR6) of Climate Change 2022:Impact, Adaptation and Vulnerability and China Meteorological Administration issued China Climate Chang Blue Book (2022). This paper presents a brief summary of the assessment report on the ecological impacts of climate change and adaption strategies, and related studies of China by reviewing additional literature. The AR6 report and related studies indicate that the ecological impacts of climate warming are significant, including advancement of phenology, extension of plant growing season; species range shift towards high latitude or elevation, tree line moving towards the top of the hill; local extinction of species or habitat loss; increase in frequency, severity and range of disease outbreaks. These ecological impacts of climate change may differ between species or regions. The AR6 report and related studies highlight the urgent need to take necessary measures of adaption and mitigation and to deal with the damages or challenges of climate change to the ecosystems which humans live on. These reports and studies also provide important enlightenment to China in dealing with climate change. We need to strengthen studies of climate change biology so as to take scientific and effective measures of adaptation and mitigation to climate change.
