What causes global warming, and what is it exactly ?

Question

I know its bad and a lot of stupid people don't believe it but I really don't know a lot about it. What is it ?

Answer 1

Global warming uncovered most of North America. What about that big ice sheet? Did fossil fuels cause the glacier to retreat? Our planet has always been in cycles  of temperature variations.

Answer 2

it's not real.

haha, it's been proven.

but anyways... they say it's by burning fossil fuels, and something else.

so dumb.

go burn thousands of gallons of gas in your jet, al gore.

oh oh oh!!

Answer 3

What you do not realize is that those who deny the whole scam are the smart ones as they have been burned with cons in the past and have learned a sometimes great financial cost how to spot them. Those who are supporting the con are either making huge profits from it like the oil companies that started it or have been sucked in like those that invest in Ponzi or pyramid games.

Answer 4

  Lise, you said you don't know what it is, you don't what causes it and you don't know much about it. If that's the case, how can you call people stupid who disagree with you? By your own admission, if they know just a little, they know more than you but you call them stupid. That's an illogical, rude and immature statement. There are scientists who disagree with you and many have proven AL Gore's movie to contain many errors and in some cases flat out lies. Are these scientists who have studied this event stupid? I wouldn't compare your I.Q. against them.

  Experts who believe in global warming admitted last year that the models they used to come up with the global warming theory are flawed. They continue to use those models though because that's all they have at the present. Also many of these global warming theorists disagree on whether humans are the cause.

  That information alone tells me that everything about global warming on both sides of the issue are just theories and theories can be wrong. After all, a theory is just an educated guess by definition.

  Just last week scientists found moss and insects growing under the ice in the Antarctica. They believe that 14 million years ago that desolate ice-covered land was green and supported life. Gee, did the earth warm back then and then freeze over to its present state? How did it do that if humans weren't around to drive cars and wreak havoc? Did the earth do this without human intervention? Of course it did we weren't around.

  There is a debate going on over whether or not global warming is real. There is also a debate over whether or not if it is real, is it caused by humans? These debates are being carried out by learned people on the subject. If they can't agree than we, I mean you and I are not in a position to argue the point too much. Certainly we are not in the position to call people we disagree with stupid!  We can only put our belief on one side of the other.

  I believe the earth is warming based on what I've read and I've read plenty. I also believe that the slight warming will not be detrimental to our planet and I don't believe that humans are causing it.

  When Mt. St Helens erupted in the late 70's it spewed more pollutants into the air in one day and into one small area than if all the cars in the world ran non stop every day for a year but there is no long lasting damage to that area today. It was nature doing more damage than humans could ever attempt to do and nature healed itself.  

  So since you don't know much, (your words, not mine) educate yourself and then defend a position, but please do not call people stupid who disagree with your position.  

  In 83 famous actor Ted Danson went on all the talk shows and begged people to contribute time and money to help end global cooling. He put his faith into some scientist at the time who said the earth was cooling and we are headed for another ice age. He looked into the camera and said that the oceans will be destroyed in 25 years. Well it's 25 years later, the oceans are fine and Ted Danson is on the global warming fad. He never apologised for scaring the bejeepers out of people in the 80's.

  Al gore has been on his anti global warming fight for over ten years. He has tried everything to lower his carbon footprint but in 2007 his footprint was larger than 2006. That should tell you that reducing carbon emmissions doesn't help one bit because it's not the problem.  

Answer 5

mostly air pollutions, any kind of gas that help to trap the heat on the surface increases the over-all temperature globally.

Answer 6

Global warming is the increase in the average measured temperature of the Earth's near-surface air and oceans. This happens due to conversion of the chemical enegry in fossil fuels to heat energy. Hence the amount of heat energy in the whole world is increasing. This makes the average global temperatures rise and cause the ice in polar caps to melt. If all the ice melts, the water in all the seas are expected to rise by 72 m globally. Thats why its dangerous and thats the reason we need to act and act fast on this.

Answer 7

Wrong !!! GW is a scam propigated by the Left to make money. They want gasoline to go much higher to protect the envirement. Then they want U to vote for them so they can raise the tax..

Answer 8

the sun!  

Answer 9

Your mom

Answer 10

Global warming is not a problem, people w/fabricated stories are!  This is just nature running it's course, it's a cycle nature goes thru.

Answer 11

Actually, it's not bad. Earth goes through long cycles (millions of years) of warming and cooling and there are smaller cycles within the larger ones. The temperate trend at any time is a consequence of these cycles. If this warming and cooling did not occur, Earth would be a dead planet incapable of supporting life.

Human activity has nothing to do with it. We haven't influenced accidentally and we can't influence it intentionally, nor should we try.

Answer 12

Let's start with the normal basics. Well, light and heat from the sun come to the earth as rays. they bounce off the earth's surface and some heat can escape to space, and some heat stays on earth. areas on earth closer to the sun get more heat this way, the polar ice caps don't.

well, due to the huge increase of CO2, the atmosphere has gotten thicker and thicker. because of this, more heat waves get trapped on earth, causing higher temperatures. this is why the polar ice caps are melting. by the end of our lifetime, polar bears will be extinct.

Answer 13

a lot of things but mainly the increased CO2 levels which come from us with our cars, factories, etc....

see the movie "An Inconvenient Truth"

Answer 14

Global warming AND cooling are both dominated by the Sun's activity.  If there is no Sun..... there is only cooling (like REAL cool).

At this point, it has not been proven that CO2 emissions.....natural or manmade .....have any effect on our climate.

Keep in mind that just because someone does not believe in something that is unproven.... only a guess.... does not make one stupid.  To blindly believe in something not based on facts makes one a follower of religion...... not science.

Answer 15

All kinds of things - mostly the sun - barely humans.  Global warming is not a problem.

Answer 16

Global warming is a natrual cycle that occurs to regulate the envirmet of the earth relative to the interactions of the cosmos, solar wionds magnetic storms, solar flares.  IT has been recorded that the earth has been much hotter in the 1200 and much cooler in the late 1800's but some have decided in an new effort to control sheep populas taht we as humans jsut being here are causing dramtic change to the envorment and if we dont do exactly waht they say( which changes on a daily basis) we are all going to die by 2012. Now when those I mentioned above start selling all asssets and living in a tee pee I will belive that i need to make some changes..

Answer 17

To do with the CO2 gasses building up in the atmosphere and creating a  kind of shield around the earth, and then with the heat we produce due to western ways the heat builds up and then cant escape therefore causing global warming...in a nutshell

Answer 18

An increase level of CO2 gasses being released into the air. The CO2 traps the heat and the earth begins to warm up. The release of methane gas by the cattle industry is a big cause also. Methane is 27 times stronger than CO2.
