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).

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.

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.

electrical grids, intermittentrenewable energy sources are bestcombined with energy storage
technologies as well as energysupply technologies that canfluctuate in output yet can also

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

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.

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.
