I need to write introduction about global warming and ai have no idea of what i should write!?

Question

i need some idea of how to write an intro for globle warming can some one help me!

Answer 1

I would suggest a basic introduction paragraph defining what global warming is.

Next, explain the basics of the major points of view on what is causing global warming.

You can get basic and easy to understand information from the links here, including an article titled "Introduction to Global Warming":

Answer 2

Here's some basic info.  The websites will contain tons more stuff for you.

Some gases ("greenhouse gases") let sunlight in, which warms the Earth, and then block that heat from leaving. That's the "greenhouse effect", and it's a natural thing, mostly caused by water vapor.

Man is making excessive amounts of greenhouse gases, mostly by burning fossil fuels. That causes the delicate natural balance to go out of whack and the Earth warms. That's global warming.

It won't be a Hollywood movie style disaster. Gradually coastal areas will flood and agriculture will be damaged. But it will be very bad. Rich countries will cope, but it will take huge amounts of money. In poor countries many people will die of starvation, but not all of them.

Most scientists say, in 20-50 years. But we need to start right now to fix it, fixing it will take even longer than that.

Really good website for more information here:

http://www.nrdc.org/globalWarming/f101.a...

Lots of numerical scientific data proving it real here:

http://en.wikipedia.org/wiki/Image:Clima...

Proof that most scientists think it's real and mostly caused by us here:

Answer 3

Check out the book An Inconvenient Truth by Al Gore it is good and it will definately help you.

Answer 4

Dana or Bob are good at that read their answers

i have this to say

Global Warming is true, there are Natural fazes but we are affecting that to a great extent ,with deforestation ,desertification and pollution., especially air pollution.

A few weeks ago one of NASA's top scientists concluded that the Arctic Ocean could be nearly ice-free within five years, much faster than all previous predictions.

when the north pole is gone , you may have polar bears soon in America ,looking for a home ,

Calculations do not include the accumulative ,speeding up ,factor with time. the increase in water temperature will get faster all the time as well as the melting, when the ice is all gone the deeper cold Ocean currents will be drastically affected,which in turn will affect the warm currents,since all moving bodies of water are connected in series.

This will affect coastal climates ,world wide ,almost instantly. All aquatic flora and fauna will be affected,many dying off and others becoming invasive,

And recently In Chiapas ,and Tabasco in Mexico .more then a million people became homeless overnight with water coming up to their roofs ,because of rains from super evaporation from the forests,this had never happened before. Millions of animals died.

In India 3000 people died because of super storms .

.A few years ago in Europe 3500 people,died during a heat wave ,many of them in France .

Right now the average death toll annually is 150.000 due to Global warming

. these figures are already out of date and are expected to double soon.

In Northern China millions of people are running for their lives because regular dust storms so far have buried 900 villages under the sand and the whole of northern China is turning into a dessert.

The Sahara is growing by 7 kilometers a year all around the edges ,like a slow burning fire shriveling up their neighbors In the Kalahari huge rivers have dried up and thousand of species are gone due to their habitats disappearing .

The biggest changes are invisible at micro biotic levels species are becoming extinct ,others are multiplying ,

This affects the insect populations that follow ,and changes in that ,affect all that follows in the food chains ,

All life is interrelated of both flora and fauna, And since we are on the top of the food chain ,

we are always the last to know.

So Global warming has its toll there are incidents all over the world ,

However

confusion rules the day ,i am beginning to think that SCIENCE HAS BEEN INVADED WITH POLITICS AND HUMAN EMOTIONS

The truth is being distorted at high levels,

And lies have been weaved in.

Some of the real dangers are being hidden because there are no solutions , Public could panic.and Authorities would loose control .

Besides Corporations have other priorities and changes will cause loss of profits ,this also affects the truths being published

Others facts are exaggerated so that the phenomena can be used to milk the people.

This is further complicated with Arrogance that will not admit that mankind could be guilty, or that Gods could be out of control ,unloving or incompetent

But I do not think we can make a real difference anymore to change the tide.

On a Global scale,Humanity is not co operative enough .

The poor regions have other priorities such as daily survival.

There is a lot we can do about being more responsible with what we got ,

In the first world countries many do not care or are more interested in Global Control than Global Warming.

Answer 5

It is really about a Global warming Tax

World Temperatures according to the Hadley Center for Climate Prediction. Note the steep drop over the last year.

A twelve-month long drop in world temperatures erases global warming

Over the past year, anecdotal evidence for a cooling planet has exploded. China has its coldest winter in 100 years. Baghdad sees its first snow in all recorded history. North America has the most snowcover in 50 years, with places like Wisconsin the highest since record-keeping began. Record levels of Antarctic sea ice, record cold in Minnesota, Texas, Florida, Mexico, Australia, Iran, Greece, South Africa, Greenland, Argentina, Chile -- the list goes on and on.

No more than anecdotal evidence, to be sure. But now, that evidence has been supplanted by hard scientific fact. All four major global temperature tracking outlets (Hadley, NASA's GISS, UAH, RSS) have released updated data. All show that over the past year, global temperatures have dropped precipitously.

Meteorologist Anthony Watts compiled the results of all the sources. The total amount of cooling ranges from 0.65C up to 0.75C -- a value large enough to erase nearly all the global warming recorded over the past 100 years. All in one year time. For all sources, it's the single fastest temperature change every recorded, either up or down.

Scientists quoted in a past DailyTech article link the cooling to reduced solar activity which they claim is a much larger driver of climate change than man-made greenhouse gases. The dramatic cooling seen in just 12 months time seems to bear that out. While the data doesn't itself disprove that carbon dioxide is acting to warm the planet, it does demonstrate clearly that more powerful factors are now cooling it.

Let's hope those factors stop fast. Cold is more damaging than heat. The mean temperature of the planet is about 54 degrees. Humans -- and most of the crops and animals we depend on -- prefer a temperature closer to 70.

Historically, the warm periods such as the Medieval Climate Optimum were beneficial for civilization. Corresponding cooling events such as the Little Ice Age, though, were uniformly bad news.
