World Must Adapt to Unknown Climate Future
e is still great uncertainty about the impacts of climate change,according to the latest report from the Intefgovernmental Panel on Climate Change,released 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.
y’s report is the second of three instalments(分期连载)of the IPCC’s fifth assessment of climate first instalment,released last year,covered the physical science of climate stated with increased certainty that climate change is happenin9,and that it is the result of humanity’s greenhouse gas new report focuses on the impacts of climate change and how to adapt to third instalment,on how to cut greenhouse gas emissions,comes out in April.
latest report backs off from some of the predictions made in the previous IPCC report,in ng the final editing authors also retreated from many of the more confident projections from the final draft,leaked last IPCC now says it often cannot predict which specific impacts of climate change—such as droughts,storms or floods——will hit particular places.
ead,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”.
New Scientist breaks down what is new in the report,and what it means for humanity’s efforts to cope with a changing climate.A companion article,“How climate change will affect where you live”,highlights some of the key impacts that different regions are has changed in the new IPCC report?
essence,the predictions are intentionally of the firlner language from the 2007 report about exactly what kind of weather to expect,and how changes witl affect people,has been replaced with more cautious scale and timing of many regional impacts,and even the form of some,now appear uncertain.
example,the 2007 report predicted that the intensity of cyclones over Asia would increase by 10to 20 per new report makes no such larly,the last report estimated that climate change would force up to a quarter of a billion Africans into water shortage by the end of this new report avoids using such firm numbers.
report has even watered down many of the more confident predictions that appeared in the lcaked rences to“hundreds of millions”of people being affected by rising sea levels have been removed from the summary,as have statements about the impact of warmer temperatures on crops.“I think it's gone back a bit,”says Jean Palutikof of Griffith University in Brisbane,Queensland,Australia,who worked on the 2007 report.“That may be a good the fourth [climate assessment]we tried to do things that weren’t really possible and the fifth has sort of rebalanced the whole thing.”
So do we know less than we did before?
really,says Andy Pitman of the University of New South Wales in Sydney, is just more rigorous language.“Pointing to the sign of the change,rather than the precise magnitude of the change,is scientifically more defensible,”he says.
also know more about what we don’t know,says David Karoly at the University of Melbourne.“There is now a better understanding of uncertainties in regional climate proj ections at decadal timescales(时标).”
Are we less confident about all the impacts of climate change?
e are still plenty of confident predictions of impacts in the reponv—at least in the draft chapters that were lcaked last year,and which are expected to be roughly the same when they are released later this e include more rain in parts ofAfrica,more heatwaves in southem Europe,and more frequent droughts in Australia(see“How climate change will affect where you live”) also remains clear that the seas are do we prepare in cases in which there is low confidence about the effects of climate change?
