3. Definition of Terms Weather - is the specific condition of the atmosphere or “actual state” at a particular place and time. Climate - is the “average weather” or normal state of the atmosphere and its long term variability over a particular period (say over month, a season, a year or several years)
4. (Global) Climate System – interactive system consisting of 5 major components, forced or influenced by various external forcings (i.e.,sun and human activity) Cryosphere
5. Global warming refers to the increase in the earth’s mean temperature due to the so-called enhanced greenhouse effect.

7. Source: OSTP Water vapor and carbon dioxide (CO2) are the two most abundant natural heat-trapping gases in our atmosphere. These and other gases keep the Earth’s surface about 60°F (33 °C) warmer than it otherwise would be. Without this natural greenhouse or blanket effect, life as we know it would not be possible Land,vege, ocean,etc. trapped by Sunlight - heat energy

59. Temperature Projection 1.8-3 C increase 1.8-3 C increase 2.1-2.7 C increase 2.1-2.7 C increase Increase in entire archipelago; Greater increase in MAM FUTURE (2075-2099) Solis,2009 (Capacity Development for Adaptation to Climate Change in Asia-Climate Change Analysis)
60. RAINFALL SCENARIO END OF 21 ST CENTURY JFM - An increase in rainfall (0.5 - 2 mm/day) decrease over the mountainous areas ( W.Luzon ) Eastern part wet, will be more wet more dry increase + Areas statistically significant at 95% level AMJ - Rainfall reduction in entire archipelago (5 - 20%); greater decrease over Luzon and the mountainous areas

63. Intensity of precipitation events is projected to increase. Even in areas where mean precipitation decreases, precipitation intensity is projected to increase but there would be longer periods between rainfall events. “ It rains less frequently, but when it does rain, there is more precipitation for a given event.” (Tebaldi et al. 2006) Extremes will have more impact than changes in mean climate

INTERNATIONAL RESPONSE TO ADDRESS CLIMATE CHANGE 1990 1 st IPCC report - the planet seems to be warming - Human activity seems to be responsible for it 1992 2 nd Earth Summit, Rio de Janeiro - UNFCCC was adopted - Call for a stabilization of GHG emissions by 2000 1994 UNFCCC entered into force - Philippines ratified UNFCCC 1997 Kyoto Protocol was adopted at COP 3, Kyoto Conference 2005 Kyoto Protocol entered into force 2007 4 th IPCC report - Equivocally, the planet is warming due to man-made activities

Editor's Notes
Greenhouse is made of glass or strong semi-transparent plastic material. When the sun shines, it produces energy in the form of sunlight, passes thru the glass and heats inside of that greenhouse, the ground, plants, vegetable, etc. Some of IR is absorbed, but most of it escapes to space.
global average air temperature increased by 0.74°C from 1906 to 2005 Strong temperature increase since 1975 (unprecedented)
Global mean temperatures has increased; b. Sea levels are rising; and c. Snow cover in Arctic has decreased
More intense and increase in frequency of events
These are based on what has been observed locally, so we need local impact assessment of future changes in climate. That’s why there is an increasing demand…
Our available data shows that there is an increasing trend in the number of tropical cyclones in the Visayas and decreasing trend in Mindanao. There is no trend in the number of tropical cyclones in Luzon. In general, there is no trend in the total number of annual tropical cyclones in the Philippines (the blue bar represents 1951-1980 30-year total number of TC, pink bar represents 1961-1990 30-year total TC, and yellow shows the 1971-2000 30-year total TC).
Increase in incidence of diseases in animals and crops Availability of food could decline; Prices will rise as a result; Employment opportunities may become less; More people could face hunger and starvation
