Climate change, especially global warming has become concern for the international community and governments, which is not only a major environment problem closely related to the survival and development of the humanity, but also a hotspot and frontier in basic science research around the world. Human social and economic activities are so wide and intensive that they have exerted significant impacts on the global climate. In recent one hundred years, global warming was caused by greenhouse gases, mostly carbon dioxide. At the same time, high-intensive regional human activities, such as air pollution, land cover change, bring greater uncertainty in the understanding of regional and global climate change.
As an eastern coastal province, Jiangsu is characterized by intensive human activities and advanced economic development, whose socio-economic development is closely related to monsoon climate changes. On the one hand, as an industrial province, Jiangsu features high carbon emission intensity as well as a huge total amount, leading to serious air pollution and other environment problems. These problems call for energy conservation and emission reduction, and place high demands on the transformation of economic development mode and innovation in production processes. On the other hand, rapid urbanization and its construction is undergoing in Jiangsu Province, southern Jiangsu becoming a demonstration area for modernization in China. Frequent extreme precipitation caused by climate change has led to serious urban waterlogging in many cities of Jiangsu Province (such as Nanjing), resulting in serious losses of people’s life and property. To forecast and respond to disasters, especially to undertake city infrastructure improvement and planning, basic scientific research is in an urgent need. At the same time, as a major agricultural province, situated in the eastern monsoon region, Jiangsu features maximum interannual variability of precipitation. At the end of lower reaches of the Yangtze River, the province is also susceptible to precipitation in the Yangtze river basin, Natural disasters caused by climate change exert huge impacts on agricultural production in this region, thus responding to climate change is of the first importance.
In general, based on international frontier of the climate change, the Collaborative Innovation Center (Collaborative Innovation Center for Climate Change) meets major demand for national and local economic and social development, and focuses on issues about Asian monsoon climate system. The center brings different disciplines and different units together, carrying out research mechanism reform and improving the overall innovation capability. That’s how it gains in-depth knowledge of basic laws and key mechanism of the climate change and its related natural disasters in eastern China against the background of global warming. It works to improve numerical modeling and prediction for issues in question, offering new ways and methods to come up with scientific measures to orderly respond and adapt to the climate change. Though collaborative innovation, the center gathers and cultivates a number of top-notch teams and talents specialized in the climate change, contributing to rapid and sustainable development of the related disciplines.
According to its development plan during the period of 2013-2016, the Collaborative Innovation Center focuses on laws, mechanism and predictability of interdecadal variation of the Asian monsoon climate. The key scientific problem to be solved is relative contribution of the climate system's natural variability and regional human activities to climate change in China and the East Asia in 10-30 years.
Its main tasks include the following aspects:
1) Decadal oscillation of Ocean-Atmosphere-Land Coupled monsoon system
2) Human activities on the decadal change modulation of monsoon system
3) Predictability and prediction theory on decadal changes in monsoon system
4) Changes of monsoon climate and prediction and orderly adaptation to its impacts in the next 10-20 years
