White Paper | Science and Impacts Program. Extreme Weather and Climate Change : understanding the Link, Managing the Risk
Typically, climate change is described in terms of average changes in temperature or precipitation, but most of the social and economic costs associated with climate change will result from shifts in the frequency and severity of extreme events.[1] This fact is illustrated by a large number of costly weather disasters in 2010, which tied 2005 as the warmest year globally since 1880.[2] Incidentally, both years were noted for exceptionally damaging weather events, such as Hurricane Katrina in 2005 and the deadly Russian heat wave in 2010.

Published by: C2ES ; 2011Typically, climate change is described in terms of average changes in temperature or precipitation, but most of the social and economic costs associated with climate change will result from shifts in the frequency and severity of extreme events.[1] This fact is illustrated by a large number of costly weather disasters in 2010, which tied 2005 as the warmest year globally since 1880.[2] Incidentally, both years were noted for exceptionally damaging weather events, such as Hurricane Katrina in 2005 and the deadly Russian heat wave in 2010. Other remarkable events of 2010 include Pakistan’s biggest flood, Canada’s warmest year, and Southwest Australia’s driest year. The early months of 2011 continued in similar form, with “biblical” flooding in Australia, devastating drought and wildfires in Texas, New Mexico, and Arizona, and unprecedented flooding in North Dakota.[3] ...

Challenges in Estimating and Understanding Recent Changes in the Frequency and Intensity of Extreme Climate and Weather Events
This paper briefly reviews some aspects of the current status of research on changes in climate extremes, identifying gaps and issues that warrant additional work. This paper focuses primarily on the historical instrumental record, giving a sense of the nature of the results that have been obtained, challenges that arise from observational, methodological and climate modelling uncertainties and discussing the extent to which detection and attribution research has been able to link observed changes to external forcing of the climate system. It also very briefly discusses projections for the 21s ...Challenges in Estimating and Understanding Recent Changes in the Frequency and Intensity of Extreme Climate and Weather Events

Published by: WMO ; 2011This paper briefly reviews some aspects of the current status of research on changes in climate extremes, identifying gaps and issues that warrant additional work. This paper focuses primarily on the historical instrumental record, giving a sense of the nature of the results that have been obtained, challenges that arise from observational, methodological and climate modelling uncertainties and discussing the extent to which detection and attribution research has been able to link observed changes to external forcing of the climate system. It also very briefly discusses projections for the 21st century. Extremes are not discussed on paleo time scales, in the context of the present (i.e., short term forecasting), or in the context of climate surprises (extreme tipping points). These choices reflect our desire not to attempt too broad a review of the topic due to space constraints of this short paper, as well as a view that very high priority should be given to reducing uncertainty in our understanding of historical changes in extremes over the instrumental period as a prerequisite to confidently predicting changes over the next century. This includes the development of improved and comprehensive observational records, improvement in our ability to confidently detect changes in observations through the development of better physical models, forcing data sets and more power statistical techniques, the development and refinement of our understanding of the physical processes that produce extremes, and continued improvement in our ability to attribute causes to those changes. This does not imply that research on extremes on paleo timescales or on the projection of future changes in extremes is of lesser importance, but rather that overall progress on understanding implications of ongoing and future changes in extremes will be strongly dependent upon our ability to document and understand changes in extremes during the period of history that has been (and continues to be) most comprehensively and directly observed.

Attribution of Weather and Climate-Related Extreme Events
Unusual or extreme weather and climate-related events are of great public concern and interest, yet there are often conflicting messages from scientists about whether such events can be linked to climate change. There is clear evidence that climate has changed as a result of human-induced greenhouse gas emissions, and that across the globe some aspects of extremes have changed as a result. But this does not imply that the probability of occurrence (or, given a fixed damage, risk) of a specific type of recently observed weather or climate event has changed significantly as a result of human in ...World Meteorological Organization (WMO) ; Myles R.

Published by: WMO ; 2011Unusual or extreme weather and climate-related events are of great public concern and interest, yet there are often conflicting messages from scientists about whether such events can be linked to climate change. There is clear evidence that climate has changed as a result of human-induced greenhouse gas emissions, and that across the globe some aspects of extremes have changed as a result. But this does not imply that the probability of occurrence (or, given a fixed damage, risk) of a specific type of recently observed weather or climate event has changed significantly as a result of human influence or that it is likely to become more or less frequent in the future. Conversely, it 2 is sometimes stated that it isn’t possible to attribute any individual weather or climate event to a particular cause. Such statements can be interpreted to mean that human induced climate change could never be shown to be at least partly responsible for any specific event. In this paper we propose a way forward through the development of carefully calibrated physically-based assessments of observed weather and climate-related events and identification of any changed risk of such events attributable to particular factors.

Экстремальные явления погоды в условиях изменяющегося климата : От ретроспективы к предвидению
Связанные с погодой и климатом разрушительные события, зарегистриро-ванные в последние годы, привлекли внимание широкой общественности, правительств и средств массовой информации. В настоящей брошюре приводится ряд примеров экстремальных явлений, произошедших за по- следнее десятилетие (2001-2010 гг.). Некоторые из этих явлений были сравнимы с наиболее значительными событиями прошлых лет или превос- ходили их по интенсивности, продолжительности или географической про- тяженности.Published by: BMO ; 2011
