Climate Change Impacts on Central China and Adaptation Measures

摘要

In Central China,the obvious climate change has happened along with global warming.Based on the observational analysis,the climate change has significant efects,both positive and negative,in every field within the study area,and with the harmful efects far more prevalent.Under the scenario A1B,it is reported that temperature,precipitation,days of heat waves and extreme precipitation intensity will increase at respective rates of 0.38 C per decade,12.6 mm per decade,6.4 d and 47 mm per decade in the 21st century.It is widely believed that these climate changes in the future will result in some apparent impacts on agro-ecosystems,water resources,wetland ecosystem,forest ecosystem,human health,energy sectors and other sensitive fields in Central China.Due to the limited scientific knowledge and researches,there are still some shortages in the climate change assessment methodologies and many uncertainties in the climate prediction results.Therefore,it is urgent and essential to increase the studies of the regional climate change adaptation,extend the research fields,and enhance the studies in the extreme weather and climate events to reduce the uncertainties of the climate change assessments.
