Climate Change - Abrupt and Irreversible
Changes Expected in Future
Humaninduced

and
global

are
ahuge,
highly
topical
and
rapidly changing environmental issue that humanity is facing today. The
IntergovernmentalPanelonClimateChange(IPCC)reportpublishedinyear2007
stronglyconfirmedthatclimatechangeduetohumanactivitiesishappeningand

Increasedsalinizationof freshwater resources leading toscarcityof freshwater.
These findings strongly suggests that climate change is happening, and is
projectedto
increase
due
to
the
ongoing
and
increasing
rate
of

emission into the atmosphere. Climate change and greenhouse gases in the
atmosphere have reached to a stagewhere consequences can not be avoided
