    UNDERSTANDING

    GLOBAL WARMINGTo fully understand what is meant byglobal warming and climate change the

    greenhouse effect must first be understood.The greenhouse effect is the process wheresolar radiation (short wavelength radiation)from the sun reaches the earths surface

    where its converted to heat energy (longwavelength radiation).

    3/29

    The majority of sunlight is absorbed by theearths surface (landmass and water) andwarms it, whilst the rest is reflected by theearth back into space. Polar ice reflects 90% ofsolar radiation back into space, whereas waterabsorbs 90% of the energy it receives. In

    addition, the warm surface of the earth emitslong wavelength radiation (infrared) and this isabsorbed by the greenhouse gases (a natural aswell as manmade part of the earths

    atmosphere

    IMPACTSOF THE WARMING

    GLOBAL TEMPERATURES WILL INCREASEFROM 1.1 TO 6.4 DEGREES IN NEXT 100 YEARS

    Rise by 0.8 degrees-ocean warming, arctic ice cap

    melting, species extinction , extreme weatherevents.

    1 degree rise-coral reefs destroyed, islandnations under water.

    2 degree rise-Greenland melts, polar bearsextinct, water supply affected.

    Increasing temperatures

    3 degree rise-environmental refugees,food shortage, amazoncollapses

    4 degree rise-millions of

    refugees, 1/3 rd ofbangladesh under water,permafrost melts releasinggases

    5 degree rise-most of theworld uninhabitable, earthhotter than in 55 million

    years 6 degree rise-mass

    extinction

    The Solar Power

    Solar Towers can beconstructed to poweran entire city.

    The tower hasphoto-sensitive cellson allsides

    The tower issurrounded by mirrors

    The cost of suchtowers is too steep,hence it has become achallenge forengineers.

    The only technology comparable in efficiency of conversion of sunlight is the solarengine running on high-temperature heat, produced by a solar concentrator (afocusing trough or dish). This technology was commercialized for a brief time notvery long ago with the help of subsidies and will probably return.

    Wind Energy

    Wind power is playing animportant role in severalcountries, notably Germany

    and Denmark. The spaces betweenturbines on land can be usedin many ways, including foragriculture and grazing.

    To be practical for large-scale use in

    electrical grids, intermittentrenewable energy sources are bestcombined with energy storage

    technologies as well as energysupply technologies that canfluctuate in output yet can also

    operate a large fraction of the time.

    Land between turbines can be usedfor agriculture, grazing, and other

    purposes.

    Vertical Farms

    With increase inurbanization arable land isdecreasing quickly

    A Feasible solution for thefuture is construction ofvertical farmswhich will

    solve the problem of foodscarcity for underdeveloped nations andprovide clean air at thesame time

    The construction of suchfarms will be a civilengineering challenge butits results will be

    phenomenal

    Just a thousand ships likethese (called the albedo

    yachts by the designers) willcheck temperature rise dueto global CO2 doubling .

    Scientists still have todetermine the side effectson the rain cycle due toexcess clouds

    CO2 gobbling Plankton

    By adding nutrientslike iron or urea ,orby pumping deep-sea water to the

    ocean surface,ocean fertilizerscould stimulate CO2 gobbling

    plankton blooms,like the naturalred tides in NewZealand

    Carbon capture and

    storage Carbon capture and storage(CCS) is a plan to mitigate climate

    change by capturing carbondioxide (CO2) from large pointsources such as power plants and

    subsequently storing it awaysafely instead of releasing it intothe atmosphere.

    Technology for capturing of CO2 isalready commercially available forlarge CO2 emitters, such as power

    plants. Storage of CO2, on the otherhand is a relatively untried conceptand as yet (2007) no powerplantoperates with a full carbon captureand storage system.

    ENHANCED NATURAL

    SINKS Enhancing natural sinks entailsfostering the biological absorption ofcarbon and increasing its storageabove and below the ground by, forexample, reducing deforestation,creating new forest plantations on

    non-forested land, or expandingconservation tillage.

    Modifying agricultural

    practicesThe world could take somepressure off the energysystem by modifying theagricultural practices onnearly one-fifth of all

    cropland to bring aboutconservation tillage.It could create 60 millionhectares of sustainableplantationson nonforestedland and set a new course

    to eliminate tropicaldeforestation within 50years.

    CONCLUSIONToday we are senselessly exploiting ourresources and enjoying ourselves. This hasto stop. All we have to do is cut down on

    our exploitation in all possible ways, live asimple lifestyle, revert to what Gandhitold us almost a hundred years ago, besensitive to natures needs and remove

    from our lives ,everything that isunnecessary.
