Definition of TermsDefinition of TermsWeather - is the specific condition of the atmosphere or “actual state” at a particular place and time.time.

Climate - is the “average weather” or normalnormal state of the atmosphere and its long term variability over a particular period (say over month, a season, a year or several years)

(Global) Climate System – interactive system consisting of 5 major components, forced or influenced by various external forcings (i.e.,sun and human activity)

Global warming refers to the increase in the earth’s mean temperature due to the so-called enhanced greenhouse effect.

Page 6: Villamor Jan29

Source: OSTPWater vapor and carbon dioxide (CO2) are the two most abundant natural heat-trapping gases in our atmosphere.

Land,vege, ocean,etc.

trapped by

Sunlight - heat energy

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

Human activities contribute to climate change by causing changes in Earth’s atmosphere in the amounts of greenhouse gases, aerosols and cloudiness.

Is this the Future?• Global warming is inadequate to describe the

changes we can expect in the Earth System.

• The focus is not on temperature alone but also on the anticipated shifts in climate variability; specifically the

• projected increase in the frequency and severity of extreme events.

Page 36: Villamor Jan29
Page 37: Villamor Jan29

• Mitigation - human intervention to reduce the source and enhance the sinks

• Adaptation- capacity to cope up with the adverse impacts of climate change- To reduce vulnerability

• Access to Financial resources - part of developed countries’ obligation under the convention to enhance adaptive capacities of developing countries

• Technology Transfer

RAINFALL SCENARIO

Page 61: Villamor Jan29

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
