The World Weather Watch and the Operations of NMS
Numerical weather prediction led to climate model
development and studies of climate variability
(e.g. ENSO) and climate change. - Climate
services to a wide range of socio-economic
activities

MONITORING HYDROLOGICAL CYCLE FOR CLIMATE CHANGE

• Hydrological data from478 000 stations (river
  basin runoff, evaporation, ground water, etc) may
  
• provide early warning signal of climate change.
• WHYCOS (MED-HYCOS,etc.) - increased exchange of
  hydrological data for climate studies.

Climate-induced increases in sea level are caused
by thermal expansion of the oceans and melting of
land ice and ice sheets

Food production needs to double to meet the needs
of an additional 3 billion people in the next 30
years
Climate change is projected to decrease
agricultural productivity in the tropics and
sub-tropics for almost any amount of warming
From IPCC 2001
12
Wood fuel is the only source of fuel for one
third of the worlds population Wood demand will
double in the next 50 years Forest management
will become more difficult due to an increase in
pests and fires
From IPCC 2001
13
Climate change is projected to decrease water
availability in many arid- and semi-arid regions
One third of the worlds population is now
subject to water scarcity
Population facing water scarcity will more than
double over the next 30 years
From IPCC 2001
14
Estimated 10-15 of the worlds species could
become extinct over the next 30 years
Biodiversity underlies all ecological goods and
services
Climate change will exacerbate the loss of
biodiversity
From IPCC 2001

Agricultural Lands
Coastal Zones
Forest Lands
Freshwater Systems
Arid Lands Grasslands
Food and Fiber Production Provision of Clean and
Sufficient Water Maintenance of
Biodiversity Maintenance of Human Health Storage
and cycling of Carbon, Nitrogen, Phosphorus
Climate change will affect the ability of
ecological systems to provide a range of
essential ecological goods and services
