4. GLOBAL WARMING
Global warming is a long-term rise in the average
temperature of earth’s climate system, an aspect
of climate change shown by temperature
measurements and by multiple effects of the
warming.
• The term commonly refers to the mainly human-
caused observed warming since pre-industrial
times and its projected continuation.

5. MAJOR CAUSES OF
GOLBAL WARMING
• There are many possible mechanisms that can
cause the warming of the atmosphere, for
example:
• Natural variation – the climate becomes warmer by internal
chaotic dynamics of the earth-atmosphere system (that is, no
external influence).
• Solar activity – either direct increase of solar energy output or
indirect “trigger” mechanisms due to solar activity (though
nobody knows how) may cause the surface temperature to go
up.
• Greenhouse effect – increasing “greenhouse” gases such as
CO2, CH4, N2O, CFC,…etc. (actually H2O is very efficient, too,
but at present it is assumed to be in steady state).
• The last one is presently thought to be the most likely cause
of the global warming

15. WHAT TO DO
Civil engineer should design ecofriendly structure
which could not effect climate condition.
Environment condition could not effect. Ecosystem
should be balanced. No need to construct heavy
type structure in hilly areas because that type of
structure effect the environment and ecosystem.
