Impact of Climate Change
Additional people with Increased water stress (50C)
20 to 30% species at inc. high risk of extinction (2-30C) Decrease (low latitudes) (1-20C) 30% loss of coastal wetlands(3-40C) Increased mortality due to heatwaves, floods and drought (10C)
Reconfiguration of coastlines and inundation of low-lying areas (50C)
Increase (mid & high latitudes) (1-20C) (impact is
beneficial)

Future climate change is likely to continue to adversely affect human health in Asia
Disease primarily associated with climate change are expected in South and South- East Asia Increases in coastal water temperature would exacerbate the abundance and/or toxicity

SLIDE 15
Efforts to cope with the impacts of climate change and attempts to promote sustainable development share common goals and determinants
- Access to resources
- Equity in the distribution
- f resources (i.e. human
and social capital)
- Access to risk-sharing
mechanisms
- Abilities of decision-
support mechanisms to cope with uncertainty
SLIDE 16
Nonetheless, some development activities exacerbate climate-related vulnerabilities
High rise building in urban areas Processing plants Road development Land use change/Mining in natural forests (Irresponsible mining)
SLIDE 17
Climate change will result in net costs into the future; these costs will grow over time
By 2080, it is likely that : 1.1 to 3.2 billion people will be experiencing water scarcity 200 to 600 million will be hungry 2 to 7 million more per year affected by coastal flooding

Climate change will impede nations’ abilities to achieve sustainable development pathways as measured, for example, by long-term progress towards the Millennium Development Goals
