2. Climate Change: reading the signs - temperature • Global mean temperature has increased 0.76oC during 1906-2005 • The average temperature in Southeast Asia has increased 0.1–0.3°C per decade over the last 50 years • Increase in temperature varies by countries – highest change observed in Singapore . Source: IPCC, 2007

3. Climate Change: reading the signs – precipitation • Indonesia: decrease in annual rainfall during recent decades in some areas • Philippines: increase in annual rainfall and in the number of rainy days • Singapore: decrease in annual rainfall in the past three decades • Thailand: decrease annual rainfall for the last five decades • Viet Nam: decrease in monthly rainfall in July-August and increase in September to November Precipitation in Southeast Asia trended downward from 1960 to 2000. Source: IPCC, 2007

4. Climate Change: reading the signs – sea level rise • Sea level has risen at the rate 1.8 mm/year since 1961 and 3.1 mm/year since 1993. • IPCC estimated sea levels may rise 18cm - 59cm in the coming century. • The Greenland ice sheet, which could raise sea levels by 6m if it melted away, is currently losing more than 100 cubic km a year-faster than can be explained by natural melting. • In SEA, sea levels have risen 1–3 millimeters per year and projected to rise by 70 cm by 2100 .

6. Climate Change: reading the signs – projection of temperature • Global mean temperature projected to be increased by 1.8 to 5.4°C by 2100 • The mean surface air temperature in SEA would increase between 0.75–0.87°C by 2039, 1.32–2.01°C by 2069, and 1.96–3.77°C by 2100 (IPCC, 2007) .

7. Reading the signs – projection of temperature • Indonesia: increase 2.1°C and 3.4°C by 2100 under the B2 and A2 scenarios, respectively. • Philippines: increase of 1.2–3.9°C by 2080, using all the IPCC emission scenarios. • Singapore: similar to the projected global mean temperature rise of 2.5°C with a range of 1.7–4.4°C. • Thailand: increase 2–4°C by the end of this century • Viet Nam: increase in temperature of 2–4°C by 2100 • Cambodia: increase in mean annual temperatures of 0.3-0.6°C by 2025, 0.7-2.7°C by the 2060s and of 1.4-4.3 °C by the 2090s .

9. 4oC Global Temperature Rise: impacts on Southeast Asia Agriculture • Yields of cereals crops could decrease by up to 5% across South East Asia (best-case scenario) and reduction in yield may be as much as 30% or higher. Any reduction in rice yield could be very significant for large rice producers such as Indonesia, Thailand and Vietnam. Water Availability • Climate change may affect the Southeast Asian monsoon and the seasonal pattern of rainfall. Incidence of drought will increase but this does not mean decrease of average annual amount of rainfall. .

10. 4oC Global Temperature Rise: impacts on Southeast Asia Sea Level Rise • Highly populated and low-lying delta areas along the Southeast Asian coast are particularly vulnerable to sea-level rise such as Bangkok Manila, Jakarta and Ho Chi Minh City. Marine Ecosystem • Could be fundamentally altered by ocean acidification and could have a significant impact on fisheries. • Many communities in Indonesia, Malaysia, Thailand, Cambodia and the Philippines rely on fisheries for their income .

11. 4oC Global Temperature Rise: impacts on Southeast Asia Health • More incidences of heat-related illness, including heat stress, strokes and cardiovascular disorders. City populations (such as in Jakarta, Manila, Bangkok) may be particularly at risk from rising temperatures. • Vector-borne diseases, such as malaria and dengue fever may change in geographical spread, and the duration of the transmission seasons could lengthen. .

12. 4oC Global Temperature Rise: impacts on Southeast Asia Mekong Delta • The global average sea-level could rise by up to 80 cm by the end of the century and such sea-level rises could submerge the lowest parts of the delta • It could also increase the threat of saline intrusion and storm surge damage to rice crops across the region. .
