2. Can these
recent extreme events be attributed to climate change? How can we make sense out of these?
The topic of attribution has its origin in perceptibly growing number of extreme events and related impacts. Attribution of any particular climatic event to climate change is the most difficult aspect of climate services and our understanding of climate system as a whole has not reached a point where the models employed can help us attribute certain climatic event to climate change with greater accuracy (Read Nature Editorial 19 December 2012). Irrespective of the purpose of attribution (e.g. climate negotiations), the emphasis on attribution may not yield as much value and usefulness compared to putting efforts on advanced early warning systems, strengthening dissemination and efficient application of early warning information for definitive actions on the ground. There is a sufficient agreement among climate researchers for high probability of extreme events in the future and there is a clear evidence for increasing number of extreme events historically. Despite this, there is certain difficulty in attributing the impacts on the ground to climate change for the reason that more and more people have been living in vulnerable areas putting them in the harm’s way than before. The rapid economic growth is only making this trend worse as more and more infrastructure is being constructed in vulnerable areas. Hence, understanding the dynamics of population growth and distribution and its interaction with the natural hazards assumes greater significance in understanding the observed impact trends and for achieving effective risk reduction.

prepare, nationally, internationally and locally, especially in the Asia

There are several tropical cyclone classifications. Following IMD
classification, the Cyclone Phailin is classified as Very Severe Cyclone Storm
and Typhoon Haiyan as Super Cyclonic Storm.
