Extreme weather events and crop price spikes in a changing climate: illustrative global simulation scenarios
Willenbockel D. - Oxfam, 2012Agriculture is highly sensitive to climate variability and weather extremes. Various impact studies have considered the effects of projected long-run trends in temperature, precipitation and carbon dioxide concentrations caused by climate change on global food production and prices. However, according to this study, an area that remains underexplored is the food price impacts that may result from an expected increase in the frequency and intensity of extreme weather events. The study uses a global dynamic multi-region computable general equilibrium (CGE) model to explore the potential food pri ...

Learning Lessons: ADB’s Response to Natural Disasters and Disaster Risks
ADB, 2012Natural disasters triggered by extreme hazards have increased sharply worldwide since the 1980s, as measured in lives lost, displaced people, and financial cost. Asia and the Pacific have borne the brunt of the physical and economic damage. This brief highlights lessons and recommendations from an independent evaluation report that assessed ADB support for disaster prevention and recovery programs during 1995–2011. The evaluation finds that disaster recovery projects have been much more successful than ADB-supported projects overall. Nonetheless, it also finds that most ADB country programs ha ...

Climate Change and Price Volatility: Can We Count on the ASEAN Plus Three Emergency Rice Reserve?
ADB, 2012On 12 July 2012, the Association of Southeast Asian Nations (ASEAN) Plus Three intergovernmental agreement establishing the ASEAN Plus Three Emergency Rice Reserve (APTERR) entered into force. In this paper, lead author Roehlano Briones, a senior research fellow at the Philippine Institute for Development Studies, assesses the effectiveness of APTERR as a mechanism for addressing food security in light of the rising challenges of climate change and price volatility. Using Riceflow, a model of the global rice economy, he studies the possible impacts of APTERR releases on the rice market by simu ...

Green Accounting and Data Improvement for Water Resources
Winpenny James; United Nations Educational, Scientific and Cultural Organization (UNESCO) - UNESCO, 2012 (UNESCO Side publications series-No. 02)Water makes a critical contribution to all aspects of personal welfare and economic life. However, global water resources are coming under increasing pressure. It is widely recognized that over the next few decades global drivers such as climate change, population growth and improving living standards will increase pressure on the availability, quality and distribution of water resources. Managing the impacts of these drivers to maximize social and economic welfare will require intelligent policy and management responses at all levels of collection, production and distribution of water. The go ...

The connection between climate change and recent extreme weather events
What do we know about the connection between climate change and recent extreme weather events, such as the heat waves, drought, and fires? This fact sheet summarizes scientists' statements that climate change has already primed the pump for extreme weather events.
Explaining extreme events of 2011 from a climate perspective
Peterson Thomas C.; Stott Peter A.; Herring Stephanie; et al. - U.S. Government printing office, 2012This report focuses on a way to foster the growth of explaining the causes of specific extreme disaster events in near-real time. It provides an assessment on causes of historical changes in temperature and precipitation extremes worldwide to provide a long-term perspective for the events discussed in 2011. It encourages the development of an objective criteria for defining extreme weather and climate events ahead of time, and applying predetermined methodologies to minimize risk. This report should help develop the means of communicating assessments of the extent to which natural and anthropo ...

Safer Communities Through Disaster Risk Reduction (SC-DRR) in Development
The issue of climate change is set to increase the frequency of extreme weather events. Countries, therefore, are required to undertake adaptive measures to ameliorate the impact of such events; Disaster Risk Reduction (DRR) is an important element of such measures. This report, published by the United Nations Development Program and the Government of Indonesia, presents findings from the final evaluation of the Safer Communities through Disaster Risk Reduction (SC-DRR) project. The project aimed to improve safety in Indonesia by considering the ways in which DRR can be integrated into the cou ...

CAWCR technical report, 37. Large-scale indicators of Australian East Coast lows and associated extreme weather events
Extra-tropical cyclones that develop near the east coast of Australia often have severe consequences such as flash flooding and damaging winds and seas, as well as beneficial consequences such as being responsible for heavy rainfall events that contribute significantly to total rainfall and runoff. There is subjective evidence that the development of most major events, commonly known as East Coast Lows, is associated with the movement of a high amplitude upper-tropospheric trough system over eastern Australia. This report examines a number of large-scale diagnostic quantities in the upper trop ...
Assessement of selected global models in short range forecasting over West Africa: case study of Senegal
World Meteorological Organization (WMO) ; ANAMS ; National Oceanic and Atmospheric Administration (NOAA) - WMO, 2011Severe weather events in West Africa are associated mainly with meso-scale thunderstorms and squall lines. Forecasting such severe weather to reduce the risk of hazards is one of the challenges faced by many met services. However, the recent progress in the area of numerical weather prediction has enabled some countries to forecast these events in a better way.
Due to lack of capacity, many of the West African countries were not able to use numerical weather prediction systems effectively in their day to day forecasting activities. The CPC/African Desk has been playing big role in buil ...

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. Other remarkable events of 2010 include Pakistan’s bigge ...
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 ...
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 ...
