Do you believe there is such a thing called global warming?

Question

well something seems to be changing our weather and such.

Answer 1

Global warming is a very complex collection of many effects

this text only covers some aspects of global warming ,mainly agriculture i.e.effects of deforestation and subsequent man made desertification

water and air polution such as caused by

industrial contamination ,the contaminating effects of the cities(the internal combustion engine) ,are other stories,

and all of these are also man made ,such as the high industrial chimneys pumping contamination into the clouds and the burning of tires,some of this polution has been found in the ice in the polar regions

there are natural cycles in the planets life

but a lot is influenced by mans existance ,and this is increasing with overpopulation,putting strains on Natural resources and increasing contaminations as well as destructions of essential componants the ensure living conditions for all life forms

climate change is caused in great parts by desertification ,and most desertification is caused by man

the thinner ozone layer helps to speed this up.and this is caused mainly by air polution ,also as a result of mans actions

DEFORESTATION

in the past

the Building of the Spanish Armada deforrested Spain

the Phoenician trading fleet turned Lebanon in a dessert

Ganges Khan put everything to the sword and torch, then filled the wells with sand,

the sun finished of the job and whole countries turned to wastelands.

Today ,

Slash and burn destroys the protective vegetation (which helps to form the soil ),

leaving it open to the Sun ,and then ,wind and, water erosion.

The Plough turns the soil ,killing micro-biotic life (essential to soil building) and accelerates the drying out .

Pressures of the :vehicles, cattle and rain impact brings the salt to the surface.

Mono cultures ,aided by chemicals Exhaust and pollutes the soil .

Adding to this the effects of overgrazing has resulted in large scale desertification.

and there is less and less water (because of deforestation),to irrigate this production ,Farmers

are overpumping deep carbon aquifiers

and plowing more and more unstable lands going into the jungles and onto mountain slopes

expanding populations and expanding farming ,that has to keep pace with the expanding populations are very strong forces that encroach upon the rainforest's

clearing them for farming and settlement areas .

Rainforest's always are in third world countries and always in third world countries corruption and the need for money s highest

in North Africa,India,Mexico ,millions of people are effected by land loss and desertification and some have died as a result

,the Sahara is growing by 7 kilometers a year

and most of the desserts we know are a results of mans actions ,and they are increasing ,not getting less ,in the dinosaurs days ,there were few desserts.

collectively this planet is drying up ,

each degree rise in temperature means 10%crop loss

and there is less and less water (because of deforestation),to irrigate this production ,

and there are less and less farmers to do it..

Arable lands and their farms are lost all over the globe. Many farmers sons abandon farming and head for the cities.

Northern China is drying up, what once were millions of food producing people, are now hungry refugees ,running for their lives from the all consuming dust storms.

This will have a great effect on world food prices when they start buying at what ever cost, to feed their people.

The farmers that are left have to feed some 70 million more people than the year before but with less topsoil.

Over the last half century,

Population growth & rising incomes have tripled world grain demand from 640 million tons to 1,855 million

In the near future the global farming community will not be able to feed every body ,food prices will continue to rise. .

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.but the melting ice from Green land and the south pole ,are another matter

Global warming could be slowed down to some extent,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,instead of just some third world countries Source(s) here are a 100 ways to help

Answer 2

the evedince is there

Answer 3

Believe in it? Im hoping for it. Otherwise Ive been using aquanet and right guard all of these years for nothing.

Answer 4

Yes, it happens every so often, but we do not cause it nor can we stop it.  It has happened innumerable times, followed by Global cooling (i.e. Ice Ages).  All we can do is sit back and watch as the earth renews it's self.

Answer 5

Earth's temperature always changes.  It always changed before there were humans and it changed after humans came and it will change whether or not humans continue to exist in the future.

Scientific proof is backed up by repeated experiments and achieving similar results to discern between causality and chance.  Those who claim that there is scientific evidence for man-made global warming are either liars or idiots.  We currently lack the technology and knowledge to fully simulate earth.

Man-made global warming theory is just a hoax to push for global taxation.

Answer 6

yep, Happens every so often. See ICE AGE.

Answer 7

With all the information available these days why are people questioning this? If it's only because of political rhetoric you'd be better off getting your science information elsewhere. Politics and science don't go together very well.

Answer 8

There might but I think there is not.

Anyway, what if global warming is real and everybody trying to cool the globe is working. But it is working too well, and the globe gets so cool it will bring anoter ice age. Or, greenhouse gasses are a luck we have and we're making the globe hotter to prevent the next ice age.

Answer 9

Global warming is only in Al Gore's head.  Most of us refer to it as "fried brain symptom."  Too many drugs in the early 70s.  I'm typing this now as I sit in my freezing apt. wishing the globe would warm up a bit.

Answer 10

Well hmmmmm... We may not know for sure but we can wait and find out and see if the state of Florida becomes the ocean floor. Maybe get some swim trunks and plenty of sunscreen while were at it, will never know. If were lucky nothing will happen. Otherwise we would no longer have Atlanta but The Lost City Of Atlanta! Sounds like a great idea does it? On the same token we could always assume that all bomb threats at airports are hoaxes and not bother checking it. For the sake of avoiding the inconvenience waiting for security screening, flight delays, and cancellations. Wait and see if another 9/11 happens. Doesn't that sound brilliant? After all most bomb threats are hoaxes anyways. So I guess we should treat a global "bomb threat" as a hoax too. Just for the sake of keeping our wonderful and convenient fossil fuel energy and not have to go through the inconvenience of a few minor changes in our cars and energy sources. Great Idea! Who cares about those brats living in our future generation anyways! We can all be like Nero and play the fiddle and whine about mother nature's cruelty instead of standing up and taking action at least make an attempt to see if humans can stop global warming. If it ends up we cant let our tears overflow the oceans and flood all our coastal cities and hope for a miracle to come and save us. ( Or at least build a plastic inflatable raft out of our last drop of petroleum)
