The special report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX)  was approved and accepted by the Intergovernmental Panel on Climate Change (IPCC) on November 18, 2011, in Kampala, Uganda. The report remarks that decision and policy making needs to be based on the nature of vulnerability and exposure, and not only on the hazard itself.

  • Globally, there has been an increase in the number of warm days and nights. This means that the number of cold days and nights would be fewer.
  • Frequent and/or longer heat waves and warm spells are more likely.
  • There will be more frequent and intense heavy precipitation over most regions.
  • Economic losses from weather and climate-related disasters are increasing, albeit with large inter-annual variability.
  • As climate change impacts become more dramatic, its effect on a range of climate extremes in Asia will become increasingly important and will play a more significant role in disaster impacts.
  • High levels of vulnerability, combined with more severe and frequent weather and climate extremes, may affect places, such as low lying islands and coastal areas. These will become increasingly difficult places to live and work in.
