Listen to Liu Yu, chief forecaster of Yunnan Meteorological Bureau, explain the theme for you and understand the climate change in Yunnan. Interpretation theme: Climate change is affecting our natural environment and human environment, greenhouse climate emissions continue to rise, and the temperature of the lower atmosphere and ocean rises. Now, the temperature of the earth is 1℃ higher than that at the beginning of the twentieth century. Due to past and present human activities (including carbon emissions, land use change, forest cover, etc. ), there will be hotter days, warmer nights and heat waves in the future, and we must take measures to slow down and deal with this change. We must also respond to drought more actively through integrated drought management, and we need to provide guidance to decision makers on effective policies and land management strategies. Climate change also increases the risk of rainstorm and flood. On the basis of today's weather forecast, we should strengthen research, improve the accuracy of the forecast and protect our lives and property from disasters. Meteorological departments at all levels, from national to local, will provide the best possible scientific knowledge and operational products on weather and climate change to support China's efforts to achieve sustainable development and cope with climate change. The climate in Yunnan has become hot, dry and waterlogged since 1 year. Summary of drought and flood trends in Yunnan since meteorological records.
