    Climate Change - Abrupt and Irreversible

    Changes Expected in Future

    Humaninduced

    climate

    change

    and

    global

    warming

    are

    ahuge,

    highly

    topical

    and

    rapidly changing environmental issue that humanity is facing today. The

    IntergovernmentalPanelonClimateChange(IPCC)reportpublishedinyear2007

    stronglyconfirmedthatclimatechangeduetohumanactivitiesishappeningand

    that itsconsequencesare likelytobeserious. Inthisarticlewewilltrytofigure

    These findings strongly suggests that climate change is happening, and is

    projectedto

    increase

    due

    to

    the

    ongoing

    and

    increasing

    rate

    of

    greenhouse

    gases

    emission into the atmosphere. Climate change and greenhouse gases in the

    atmosphere have reached to a stagewhere consequences can not be avoided
