“The detailed patterns of climate on earth
are produced by a complex web of
interacting physical, chemical and biological
processes within the global climate system.”
(Bureau of Meteorology Australia, 2003)
Different ocean currents
can indicate changes in
temperature (ISDR, 2008)

“…in particular fossil fuel use and changing land-uses, are the

converted into crude

The increase in fossil fuel

If forests are cut down, no

It is no surprise that the climate

In fact, this is a natural phenomenon that has been
taking place for centuries.

How do the GHGs of the past
affect us today?
Since GHGs have different lifespans that last for at least
two years, the GHGs produced in the past are part of
the cause of climate change today.
The current situation of climate change in the
Philippines is partially caused by human activities that
took place in the 1980s, for example.
CO2 released in the past still affects climate change
today because the GHGs are still present in the Earth’s

up the Earth (CCC)

To date, the Earth has

The eleven years of 1995 to 2006 rank among
the twelve warmest years in the record of
global surface temperature (since 1850).
The linear warming trend from 1956 to 2005
(0.13 [0.10 to 0.16]°C per decade) is nearly
twice that for the 100 years from 1906 to 2005.

Greenhouse gases trap heat in the atmosphere and
make the Earth warmer.
The greenhouse effect is a natural warming process

Many people have been
pushing for the
mitigation of climate
change for many years.
Climate change, specifically global warming, was already an
issue that was raised in the early 1900’s. There was not enough
support to convince people to mitigate its effects since the
impacts were not felt during these times yet.
What is mitigation?
It is the effort of people to reduce the emissions
they contribute to climate change. (CCC)
This is achieved by decreasing the greenhouse
developing low-energy technologies
Reducing energy consumption
Switching to renewable energy
Preserving natural biomes that capture carbon dioxide
The effects of climate
change have been rapidly
increasing to the point that
mitigation is not enough.
We must learn to adapt.
Response to Address Climate Change
The impacts are inevitable. They will happen, no
matter how great the efforts will be to mitigate
Due to the fact that the Philippines has been so
vulnerable to climate change, mitigation efforts will
not be able to keep up with the increasing effects.
With this in mind, adaptation is key in dealing with
What is adaptation?
Adaptation is adjusting our human habits and
lifestyles in response to climate change and its
Communities can adapt by:
preparing risk assessments
improving agricultural methods
managing water resources
building settlements in safe zones
instituting better building designs (ISDR)
This has been a call for global
efforts, first from the developed
United Nations Framework Convention on Climate Change
the foundation of global efforts to combat global warming; opened
for signature in 1992 at the Rio Earth Summit; has almost universal
membership with 195 governments having ratified the Convention
All participating industrialized countries are required to “reduce
emissions on average 5.2 percent below 1990 levels by 2008–2012”;
ratified by 182 countries (includes all developed countries except
Even emissions from
developing countries are
rising faster than those
from developed countries.
“Their per capita emissions, however, will remain much lower than
those of developed countries. Despite being surpassed by China as
the largest annual emitter of GHGs in 2006, the United States
accounts for 30 percent of cumulative energy-related CO2
emissions since 1850 while China accounts for 9 percent.” (PEW)
