Global warming refers to an unequivocal and continuing rise in the average temperature of Earth's climate system .

In layman’s term means that the world is heating up.

Earth’s atmosphere traps solar radiation and is mediated by the presence in the atmospheres

Of gases such as co2,water vapour & methane

that allow incoming sunlight to pass through but absorb the heat radiated back from the earth’s surface .

Warming occurring in two phase 1. First phase -1919 to 1940 with average

temperature gain of .35 C2. Second phase -1970 to present ,exhibiting

temp. rise gain of .55 C .

1. Warming of the oceans .2. Rising of sea level.3. Melting of glaciers.4. Diminished snow cover in northern

hemisphere.Thus the immense geological changes will

continue their destruction unabated if steps to mitigate global warming are not taken.

OVERALL STRATEGY-Global warming can be addressed by three

key aspects: Policy Education Technology

1. Capture and bury pollution gases- By artificial tree , ocean fertilisation etc.

2. Shades the earth from solar radiation- By metal coated balloons , shoot mirror in to

space, by salt spray aerosol.

1-LAUNCH A MIRROR –size of green-land and strategically position it b/w the planet and sun.

2- LAUNCH TRILLIONS OF TINYMIRRORS- which place above earth into an L-1 orbit .

DESIGN- It made of transparent film pierced with

small holes. Two feet in diameter 1/5000 of an inch thick weight about a gram ELECTROMAGNETIC SPACE LAUNCHER-madeby sandia national lab .

The disperse fine droplets of sulphuric acid by the aircraft are in the lower stratosphere.

sulphur + water vapour =sulphate aerosols..

These get swept upward by natural wind patterns and are dispersed over the globe, including the poles.

Once spread across the stratosphere, the aerosols will reflect about 1 percent of the sunlight hitting Earth back into space.

1. Acid raid.2. Damage to the ozone layer.3. Impact on plant growth.4. Disruption of summer mansoon in africa

and asia.

By extra iron added to the sea is supposed to feed the growth of plant like phytoplankton which absorb more co2 from air during photosynthesis.

OCEANGRAPHER –JOHN MARTIN

1. How deep is deep enough to accomplish this ?

2. How does the ocean food wed change during and after a bloom ?

3. Which part’s of ocean are best for iron fertilization?

That absorbs co2 from air using leaves that are 1000 times more efficient than the real tree.

The leaves look like sheets of papery plastic and coated in a resin that contain sodium carbonate .

His tree remove one tonnes of co2 a day. Ten millions of these tree could remove 3.6

billion tonnes of co2 a year . It suggest co2 can be converted into liquid

fuel to power vehicles .

CO2 +H2O= [CO + H ]

We are trying to bring the earth’s climate on it’s pre-industrial level with efficient and effective technology at without destruction of our ecosystem.
