WEATHER, WATER AND
CLIMATE INFORMATION PROVIDE EARLY WARNINGS THAT SAVE
LIVES
Every year, disasters related to
meteorological, hydrological and climate hazards cause significant
losses of life. Although natural hazards cannot be prevented, early
warning of the impending events can significantly reduce the death and
destruction associated with them. The World Meteorological Organization
(WMO) has been working with its international partners and the National
Meteorological and Hydrological Services (NMHSs) of its 188 Members to
integrate early warning systems into emergency management and response.
Over the years, WMO has contributed to
prevention and preparedness measures, including risk assessment,
emergency planning and response, and the operation of end-to-end
multi-hazard warning systems. These early warning systems are having a
dramatic impact. Although the number of disasters due to weather,
climate or water extreme events has increased dramatically over the past
half century, the losses of life have decreased.
Early warning systems give hospitals,
medical professionals on the ground and other emergency services
providers extra lead time to alert the public, manage and allot
resources and prepare for the impending event. Early warning systems are
in place in a range of locations for various natural hazards, including
floods, droughts, heatwaves, wildfires, and sand and dust storms. Not
only do such events directly affect people’s safety and health, but they
also can deny access to life-sustaining food and water.
Climate change is posing new risks for
disaster risk management, with the Intergovernmental Panel on Climate
Change (IPCC) in its Fourth Assessment Report stating that weather and
climate extremes are very likely to increase with the changing climate.
Information on climate variability and change is increasingly being used
in disaster risk reduction efforts. Indeed, shifting to the emergency
preparedness strategies called for in the Hyogo Framework for Action
requires the use of climate information to identify, assess and monitor
disaster risks. Adopted in January 2005 by 168 Governments at the Second
World Conference on Disaster Risk Reduction in Hyogo, Japan, HFA is a
10-year plan of action to substantially reduce disaster risks by
shifting from emergency response to preparedness and prevention
strategies.
The foundation for these systems is
robust observations and monitoring. WMO and the NMHSs of its Members,
through their scientific and technical programmes and network of Global
Meteorological Centres and Regional Specialized Meteorological Centres
provide a range of observational, monitoring, forecasting and prediction
services. To strengthen early warning, these meteorological and
hydrological service providers must work in concert with local and
regional governments. Through a coordinated approach, disaster risk
reduction can occur effectively and in a timely fashion.
Facts and Figures
From 1980-2005, nearly 7 500 natural
disasters worldwide took the lives of over 2 million people, 72.5 per
cent of which were caused by weather, climate or water-related hazards
such as droughts, floods, windstorms, tropical cyclones, storm surges,
extreme temperatures, land slides and wild fires, or by health epidemics
and insect infestations directly linked to meteorological and
hydrological conditions.
In 2008, 321 natural disasters killed 235
816 people — a death toll that was almost four times higher than the
average annual total for the seven previous years, partly due to Cyclone
Nargis which left, according to UNISDR, 138 366 people dead or missing
in Myanmar.
Over the past 50 years, 90 per cent of
natural disasters have been of hydrometeorological origin.
In the period 1956-2005, the number of
disasters and related economic losses from weather-, water- and
climate-related hazards has increased nearly 10- and 50-fold
respectively. However, the reported loss of life has decreased from 2.66
million (over the decade 1956-1965) to 0.22 million (over the decade
1996-2005), due particularly to increasingly accurate early warnings.
WMO’s objective is to reduce by 50 per
cent, by 2019, the associated 10-year average fatality of the period
1994-2003 for weather-, climate- and water-related natural disasters.
Reducing deaths, protecting
communities: Examples in action
On heatwaves:
WMO, jointly with the World Health
Organization (WHO), is preparing a Guidance on Implementation of Heat
Health Early Warning Systems. Heatwaves could affect the health status
of millions of people in some parts of the world, particularly those
with low adaptive capacity. A heatwave is a period of unusually hot
weather that lasts from a few days to a few weeks. They can lead to
increased death rates from heart and respiratory diseases. Human
diseases, injury and death caused by heatwaves can be reduced when early
warning reaches communities in a timely and easy to understand manner.
The WMO-WHO Guidelines will act as a
catalyst for bringing together key players from climate, health,
emergency response agencies, decision-makers as well as the general
public for initiating action concerning the overall management of heat
as a hazard. WMO is also comparing a number of currently used techniques
in various parts of the world, looking for example at the French
Heat-Health Watch Warning System. It was established in 2004 in the wake
of the deadly European heatwave in 2003, which caused more than 70 000
excess deaths across Europe.
On sand and dust storms:
The WMO Sand and Dust Storm Warning
Advisory and Assessment System (SDS-WAS) includes 14 Operational
Research Dust Forecasting Centres that produce daily dust and sand
forecasts. Dust and sand storms pose myriad health risk to the local
populations and ecosystems. They can disable the respiratory system,
reduce visibility and damage crops. Some studies have suggested that
acute respiratory infections among children, to which sand and dust
storms contribute, are one of the major causes of mortality in
developing countries.
The sand and dust forecasts provide
important information on when and where plumes of sand and dust will
appear, and provide governments, businesses and communities with
information to help protect their people. The SDS-WAS helps ensure that
all populations affected by sand and dust storms have access to
forecasting products.
On wildfires:
A WMO-supported Regional Specialized
Meteorological Centre in Singapore is dedicated to the forecasting of
wildfires and related events. Formed after the 1997 Southeast Asia fires
that led to more than 20 million cases of smog-related health problems,
the centre provides public satellite imagery and information about the
location and size of major fires and smoke plumes.
NMHSs and partners elsewhere in the world
similarly use satellite imagery and other data to support emergency
response to wildfires. WMO, in cooperation with WHO and the UN
Environment Programme, has developed guidelines for policy-makers on
actions that can be taken in response to fires.

On the occasion of World Climate
Conference-3, which is being held 31 August to 4 September 2009 in
Geneva, Switzerland, WMO will be issuing a series of fact sheets,
including on how climate information supports disaster risk reduction
and efforts to protect human health.
