I saw the question about 'Planet Earth' and wanted to know your thoughts on Global Warming...?

Question

Do you think it is happening? Do you not? Do you care? Do you not? Tell me your thougths, concerns, and what you are doing to help Mama Earth?

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
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 very 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 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

Global Warming is definitely occurring. That is an undisputable, scientific. The earth has always warmed and cooled. The question is whether it is caused by mankind or is independent of us. My opinion is that humans have little effect on global warming. What we can control and effect is the way that the earth is trashed. Cleaning the environment is a good thing. Keep our planet clean just don't threaten me with extinction to get me to do it.

Answer 3

Personally Im very woried about it. They say that most of the countries will sink when the ice melts completly in about 10 to 15 years. Thats scary! I live in Puerto Rico and people that live in the coast already have seen the ocean water rising and less sand "space" on the beaches. PR, California, NY are some that will be under water.

I try to help by using flourecent light bulbs (MY WHOLE HOUSE HAS THEM!) , I drive a Hybrid car, and I have a solar heater for my hot water, and I recycle every week.

If everyone does just a little in their daily lives we can help stop, or slow down Global Warming.

Answer 4

I think perhaps it's kept us out of an ice age.
I can't take the cold.

The Earth has had fluctuations in climate from the time it began. Hot, cold, hot cold. It will continue to do so.

Should we take care in how we treat the environment? Of course - any other option is absurd, it's our home. Should we do it without a cause celebre? Of course. You don't need a platform to tend to your future and the future of your children.

I think it's disgusting the manner in which people are treating global warming as if they are chicken little. Its shameful that human beings cannot tend to the needs of the environment without fear of the sky falling down.

Answer 5

Global warming is real and mostly caused by us. Three reasons, with solid support, most important first.

There's an overwhelming amount of peer reviewed scientific data that says that. Short and long summaries.

Science is quite good about exposing bad science or hoaxes:

http://www.cs.cmu.edu/~dst/ATG/polywater.html

There's a large number of people who agree that it is, who are not liberals, environmentalists, stupid, or conceivably part of a "conspiracy". Just three examples of many:

"Global warming is real, now, and it must be addressed."

Lee Scott, CEO, Wal-Mart

"Our nation has both an obligation and self-interest in facing head-on the serious environmental, economic and national security threat posed by global warming."

Senator John McCain, Republican, Arizona

“DuPont believes that action is warranted, not further debate."

Charles O. Holliday, Jr., CEO, DuPont

There's a lot less controversy about this is the real world than there is on Yahoo answers:

http://www.worldpublicopinion.org/pipa/articles/home_page/329.php?nid=&id=&pnt=329&lb=hmpg1

And vastly less controversy in the scientific community than you might guess from the few skeptics talked about here:

Answer 6

It is real but it is not all our fault some of it is natural warming and the other part is out fault. I think that it is important but all we need to do is create more fuel effecente cars.

Answer 7

yes it is happening that is why it was sooooo cold in the winter.....the ice caps have allready started melting
