World Must Adapt to Unknown Climate Future
A.There is still great uncertainty about the impacts of climate change，according to the latest report from the Intefgovernmental Panel on Climate Change，released today.So if we are to survive and prosper, rather than trying to fend off specific threats like cyclones，we must build flexible and resilient(有弹性的)societies.
B.Today’s report is the second of three instalments(分期连载)of the IPCC’s fifth assessment of climate change.The first instalment，released last year,covered the physical science of climate change.It stated with increased certainty that climate change is happenin9，and that it is the result of humanity’s greenhouse gas emissions.The new report focuses on the impacts of climate change and how to adapt to them.The third instalment，on how to cut greenhouse gas emissions，comes out in April.
C.The latest report backs off from some of the predictions made in the previous IPCC report，in 2007.During the final editing process.the authors also retreated from many of the more confident projections from the final draft，leaked last year.The IPCC now says it often cannot predict which specific impacts of climate change—such as droughts，storms or floods——will hit particular places.
D.Instead，the IPCC focuses on how people call adapt in the face of uncertainty,arguing that we must become resilient against diverse changes in the climate.“The natural human tendency is to want things to be clear and simple.”says the report’s co-chair Chris Field of the Carnegie Institution for Science in Stanford，Califomia.“And one of the messages that doesn’t just come from the IPCC，it comes from history,is that the future doesn’t ever turn out the way you think it will be.”That means，Field adds，that‘'being prepared for a wide range of possible futures is iust always smart”.
