Intergovernmental Panel on ClimateChange (IPCC)

The highest scientific body formed bythe United Nations Environment Program and

the World Meteorological Society Tasked to investigate the causes and risks of

global warming

Won the 2007 Nobel Peace Prizetogether with Al Gore


8/132

What does the IPCC say?

Warming of the climate system is

unequivocal, as is now evident fromobservations ofincreases in global averageair and ocean temperatures, widespread

melting of snow and ice, and rising globalaverage sea level


9/132

From IPCCsFourth

AssessmentReport(2007)


10/132


Global atmospheric concentrations ofCO2, methane (CH4) and nitrous oxide (N2O)

have increased markedly as a result ofhuman activities since 1750 and

now far exceed pre-industrial valuesdetermined from ice cores spanning manythousands of years.


11/132


12/132


Most of the observed increase in globally-

averaged temperatures since the mid-

20th century is very likelydue to theobserved increase in anthropogenic GHGconcentrations.


13/132


Anthropogenic warming over the last

three decades has likelyhad adiscernible influence at the global scale

on observed changes in many physical

and biological systems.

Stern Review on Economics of

Climate Change

Study concludes that inactionresults in economic slowdown

Act fast or pay very high costs!!

Stabilizing CO2 at 550 ppm will cost

1% of world economic product

Not acting soon may require a costof 5 20% of world gross economic

product

More and more economic capacitywill be spent cleaning up after

disasters or helping people find food

Rainfall

Drought and deluge - fewer wet days

but on these wet days the rainswill be heavier than usual.

A strong positive increase of wet days

in the Visayas appears to be a trend,

Coupled with a reduced number of wet days in the entire

country. This will be most pronounced over eastern

Luzon.

Water1 out of every 5 Filipinos has no direct access to clean

water (WB). Climate change will make

things worse.

Health

Observed mutations of vector-borne diseases are

expected to continue, into more virulent forms.

Energy

A pronounced decrease in rainfall over Luzon andMindanao will be bad news for hydropower

generation. Visayas, which will have increased rains,

has virtually no major dams.


87/132


88/132

Salt-water intrusion

Virtually all of Pampanga's rice fields and fish

ponds will be contaminated with salt water.

Agriculture

From 1970 to 1990, 82.4% of total rice losses

in the Philippines were attributed to typhoons,

floods, and droughts (Lansigan, 2000).

Temperature

A 0.5 degree Celsius increase has already been

confirmed over the 1961-1990 mean temperature.

A study by MJ Manton in 2001 established a trend ofwarmer days and warmer nights.

It defined 4 indices of extreme temperature and

found all 4 consistently pointed to warmer days andnights in ALL WEATHER STATIONS IN THEPHILIPPINES.
