Answer by byderule
here are some reasons why the climate is changing
Lester E Brown is the director and founder of the global institute of Environment in the United states .he has compiled a report based on all the satalite information available from NASA,and all the information that has come from Universities and American embassies WORLD WIDE ,
his little book Plan B has been trans lated into 50 languages and won the best book award in 2003.
GLOBAL WARMING IS ONE OF THE MEGA THREATS OF THE PLANET EARTH AND IS AN EFFECT OF GLOBAL ENVIRONMENTAL MISMANAGEMENT
Clorofluorocarbons and gases that are released into the atmosphere by car exausts, non biodegradable materials
chief causes for global warming are the destruction of the ozone and excessive carbon production ,because we have so many cars and so much land is being deforrested.
the trees absorb carbon emisions ,which is poison to us and they produce oxygen which we need to breathe.
the sea does as well but this is limited to winter periods how ever if the waters also heat up ,the seas will absorb less than ususal and we create more and more
the trees produce the air that we need to breathe.
deforestation must be stopped before desertification goes out of control and consumes the planet.
other reasons are the burning of rubbish especially tires and plastic,and the exessive use of aerosprays which release gasses thes gasses built up ,and because we are a closed system (an enclosed package drifting in space)the trapped gasses heat up and produce the green house effect.
because of the green house effect and the desertification this planet is heating up
Each degree rise in temperature signifies 10% crop loss
DESERTIFICATION
the sahara is growing by 7 kilometres every day.
two major desserts in northern china are growing together making one giant dessert and,causing dust storms so making thousands of people refugeese
the trees evaporate a mist which ,which protects us from the strong rays of the sun .
the planet is drying out at an alarming rate.
in the days of the dinasaurs this planet was under an aquiferus manta ,a mist that covered the entire earth ,and there were no desserts .
Count how many there are today,and all of them are as a result of mans actions.
the sahara used to be forrests
arabia ,irak ,iran used to be fertile lands in biblical times
Ghengas Kahn burned all the forrests here and filled the well with water and so turning vast lands into dessert.
Bad agricultural practises is turning vast teritories into desserts ,because of over grazing and the exessive pumping of carbon aquifiers ,the surface aquifiers already having been depleted.
And the use of fertilisers and heavy machinery that compacts the ground which raises the salt in the soil.
Modern agriculture today is doing the same as ghengas kahn but in much bigger territories.
RISING SEAS
The northpole is melting ,and we will know it without ice in our life times.
this does not affect the sea level because it is ice that is already in the water.
Green land and the south pole ,which apperantly has a hole in the ozone the size of the usa,are another matter.
this is ice above the sea ,on the land, and melted water will return to the sea .and so duely affect sea levels.the sea has been rising for a long time.
in portugal remains of Roman villas have been discovered 3/4 of a mile in the sea,and in one town the locals say that the sea is eating their town ,in recent years the Dona Philipa golf cours has lost the 16th and 17th hole which have fallen of the cliffs unto the beach.
in California and Florida rising seas have flooded arable land that has been lost
so far only a few millions acres in total globaly ,but this will speed up with the increasing global warming.
And in Antartica arms of ice that even had names because the were so permanent have broken of into the sea.
Global warming is in theory reversable,but it will mean global co operation between all countries ,and taking into account human nature and the world politics ,it is unlikely that this will happen,
At least not untill we are all in the middle of planetary disastres and it becomes a battle for the survival of humanity every where.
