How did Global Warming start? pleasee help!!!?

Question

I know that Global warming is very serious&&dangerous but how did it start? Is it because of pollution?

Answer 1

It started when Dr. James Hansen wrote a computer model showing the Earth was cooling and entering into a new ice age.

Then he discovered that there was more money in global warming. So he published his fiction, democrats bought into it, John Kerry gave him $250,000.00 to endorse his campaign, and Algore gave him money as a consultant on his movie 'truth'.

And after the first million was made, we had the start of global warming.

Answer 2

It's a very good question but an accurate answer isn't all that simple.

The planet goes thrrough a series of natural cycles (to do with the way it moves in space) and these cause natural warming and cooling - it's why we have ice ages and periods without any ice. In respect of natural events then the world has always been warming or cooling. When the world first formed it was a fiery ball, it would have cooled for the first 3 or 4 billion years and then natural cycles would have kicked in. The earliest warming would have been about 1 billion years ago.

Thousands of years ago much of the northern hemisphere was covered in glaciers because the world had just gone through a cooling phase. This ended and a natural warming cycle began 18,000 years ago, it was quick to start with but for the last 10,500 years the planet has been naturally warming much more slowly.

Manmade global warming began with the Industrial Revolution, this is when we started putting large amounts of greenhouse gases into the atmosphere, this was about 200 years ago and is generally accepted as being the start of human induced global warming (it's a bit more complicated than that because some of the junk we poured into the atmosphere also caused global cooling at the same time).

The reason it started - the manmade part at least - is because we put more greenhouse gases into the atmosphere than nature can handle. We've overloaded the natural cycles and caused an accumulation of excess greenhouse gases, these have the ability to retain heat within the atmosphere and the more of them we pump out the warmer the planet becomes.

Look up info on the environmental defense website. They are a good place to start. They also have alerts you can do...That is sign petitions right now that email instantly to senatorsand other lawmakers deciding on laws protecting lands for endangered animals and saving forests and so forth. So global warming is affecting more than just the atmosphere. For example, If the polar ice caps keep melting then the temperature rises then there's no more stable ice flows the polar bears use to drift out and catch fish --making life more difficult for them. Don't you feel better knowing there are polar bears out there somewhere catching snow shoe rabbits and arctic foxes?The balance of the polar ecosystem will affect us in the long term. Public action is one way young people can be informed and change the way of the future. If your whole class joined environmental defense or any other "green" website and read the email news updates every other day changes or progress toward change can be made to stop some of the awful things that are happening/could happen. We are all connected; whether we choose to see it or not will determine how fast the earth changes for the better or for the worse. Good luck on your paper.

Now that you have the fringe answer let me give you the real answer. It started around the 1700s as the world became more industrialized. Coal and other fossil fuels threw gasses into the air which formed an umbrella keeping in the heat. In the early years there was not that much of an effect but as more and more countries industrialized more and more gasses were thrown into the atmosphere. Yes, the cycles of the sun do add to the heating but it is accepted fact that man has contributed so much pollution that it is rising far faster than it would naturally. If you want a full description of how it happened read the August 2007 issue of Scientific American. There is an article there written by members of the Intergovernmental Panel on Climate Change. That was a panel of over 1200 scientists from 152 countries that all agree that global warming is being accelerated by mankind.

Answer 5

The Industrial Revolution beginning in the 1700s and the continuing unchecked explosion of population, technology, industry, and the economies of the world throughout the 1800s and 1900s has allowed for the possibly irreversible mess we are in today. There's a whole host of horrible things contributing to this mess - pollution, specifically CO2 emissions, loss of the great forests that helped cool the planet and clear the air, greed for higher and higher profits causing the forseeable consummation of most natural resources and extinction of many plants and animals. Time will tell if climate trends will stabilize or become more severe and lead to more castrophy. In the mean time, we have to deal with a variety of what seems to be insurmountable problems, sociological, economic and environmental problems among them. Oh well, we tried. :(

Answer 6

There is no such thing as global warming. Global climate change yes, but not global warming. Humans cannot alter global climate change. It started because our earth goes through a cycle.

Answer 7

It started a long, long time ago long before man was on the scene. And don't forget about global cooling too, both have happen long before man was here.

I know you've heard that global warming is dangerous, but without global warming there would be no life on earth.

I could easily go on a rant, both pro, or con. Some people think that man is responsible for this current round of global warming, some think it's just part of the natural cycle, some think it a combination of both. Just do a seach on global warming and see for yourself.

Answer 8

The scientific consensus is that global warming is largely the result of greenhouse gases like carbon dioxide which are emitted by human civilization. We derive a large fraction of our energy from carbon based fuels like coal, oil and gas and the combustion products of these fuels are indeed pollutants.

Historically, because of its relatively "low" toxicity, carbon dioxide was believed to be harmless. Today, however, we can see that the enormous amounts of carbon dioxide and other greenhouse gases which we emit have effects on the world's climate.

A large fraction of the misconceptions about human influences on the planet can probably be traced back to the conceptual and emotional difficulty to understand how we, small as we are, are able to change something as large as the planet. The evidence, however, is not only that we are responsible for changes, but also that many of these changes are threatening our very own lives.

In the past we had this insight with mercury and heavy metals in our rivers and water supplies. Later we learned about acid rain and ozone depleting chemicals. Now we can see that greenhouse gases have a profound effect on our environment. Just like in the past we have to take this insight seriously and adapt the ways we do business. And like in the past we can do it without sacrifice. Mercury free rivers have not meant the end to our technical civilization. Neither have catalytic converters stopped us from driving our cars. Our refrigerators run just as fine, better, actually, on the new, ozone friendly refrigerants, as they did in the past. And more and more people realize that they can live just as well using half as much energy or less than they used to.

But everything important takes time. Global warming will take one hundred years to control and reverse, maybe more. We are the ones at the beginning of a process which will take all of our children's and grand children's lives. What seems so hard to us, to think first before we release something into the environment in such large quantities as we do with greenhouse gases, will be second nature to those who will follow us. But we have to do the first step and teach them how to act responsibly.

Answer 9

it didn't start. there is no global warming. some will say that the levels of co2 emissions by industries and cars and such are the cause of global warming. they don't take the fact that volcanic activity releases more co2 in a year than humans have throughout the industrial revolution, to the present day. don't worry about global warming, worry about things that are real and controllable.

Answer 10

It started as soon as people started burning other materials to create heat. It might of not been a problem in the 1600's but they were still contributing to it.

In modern times it started during the Industrial revolution.
