Why should we be concerned with global warming?

Question

i need really good reasons why?

Answer 1

dont listen to the two aboveme please. ozone has nothing to do with global warming. the  " hole in the ozone layer"   disappeared years ago.  Now its greenhouse gases  causing the heat on the eath to rise. which is a bunch of bull since thers no evidence. Oh and  since the scientists and producers who made an inconvienient truth stated after the fact " we admit we have used statistics that weer exaggerated to make a point."  in fact all the hype about global warming is nothing more than a psychic prediction. theres no evidence yet.  Al gore likes to say oh its warmer this year than any other year before!, except weve only been keeping track of temperatures in this country since the 1800's. This makes no sense since the earths cylces of cooling and  heating  take place over thousands of years. My favorite is how they blame hurricane katrinas devastation, on global warming.  The fact the  most of louisiana is below sea level and the residents of luisiana  voted against raising taxes to fix the levies to keep the sea water back, meant nothing. Oh and al gore says   global warming is the cause for  the  large amount of hurricanes, except last year we had fewer hurricanes than any year in the previous 15 years. Yep lots of evidence here. I am amazed so many people talk about global warming but no one seems to take the time to learn the facts.

Answer 2

this is also boring

and the people who are dying are far away and they are not Americans ,so it does not matter ,

but when you have to pay a lot for a drink of water ,and when the food prices hit the roof ,you will not be so bored any more ,just be patient

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 3

Listen to all the bad things people say it might cause.

Droughts Hurricanes Flooding.

IF they are right then being concerned and trying to take some action now is the correct thing to do.

IF they are wrong, Great Wonderful and we will have saved ourselves some money by saving energy :-)

I am a borderline believer / un-believer but I think we should all be concerned.

In UK schools Global Warming was taught 15 years ago (when I was a kid) when cfc's were the other big topic. Why does it seam to be an issue only now.

If we were to do something about it shouldn't we have done something about it then? since we haven't heard about it for such a long time I assumed it wasn't an immanent issue. I think politicians in USA are using it to get the liberal votes.

1 scary fact I know is CO2 has risen 37% since the start of the industrial revolution and 19% in the last 40 years. If CO2 has as bigger part in the global climate as some people think then we might have inadvertently caused ourselves big problems. I really hope they are wrong!

Answer 4

We should be very concerned about global warming because the things governments do to solve the problem may make things much worse.  If global warming is indeed happening and it is caused by carbon dioxide emissions then it is already too late to do much about it.  We can prepare for the effects but the carbon dioxide emitted in 1950, 1900, 1850 etc.  won't just go away.  Destroying millions of square miles of virgin rain forest to grow sugar cane to make ethanol is only one of the idiotic plans being considered.  Paying some people to plant trees in Africa, selling "carbon credits" based on the trees, then, when the trees die in a year or so, doing it all over again is one of the goofier ideas being sold to the gullible.

Answer 5

to simply things it messes up the ozone layer which protects us from nuclear radiation produced by the sun... without the ozone we are expose to nuclear radiation and we would be screwed...

Answer 6

coz if you don't, you'll end up with skin you wont want to look at...with no ozone of course..

and ...loads of things..better look for an article Yahoo!Search!

Answer 7

because if we keep treating the earth like c**p then there will be no ozone left.
