Global warming is one of the most serious challenges facing us today. To protect the health and economic well-being of current and future generations, we must reduce our emissions of heat-trapping gases by using the technology, know-how, and practical solutions already at our disposal.
Global warming is real and effects our climate, temperatures, crop growth, even us physically.
But there are many ideas to curb this effect that humans have on the planet and many countries are working diligently to solve some of the problems.
Allot of the problem is why won't the big oil companies such as Exxon and others start to reduce the amount of petroleum dependent products they support. The answer is MONEY. Many people are getting very rich by causing the masses to believe that we need these things.
So global warming is real and will continue until the masses conceive a viable alternative.

Don't think whatever you learn and best one million/two of what you spot. Of direction, Global warming is truly. The final Ice age has long past away, has it no longer? So, we have to have worldwide warming. Do individuals give a contribution to worldwide warming? Probably a few small quantity, in spite of everything we ARE Warm and we breath in oxygen and breath out CO2, we have to be side of the obstacle. What is Al Gore going to do approximately it? Kill a entire lot of individuals? Invariably that's what Socialists do once they take manipulate of a nation. Is that higher than destroying their financial system and inflicting thousands to starve to dying?

Yes, global warming is real, BUT so is global cooling!
The earth heats and cools. We can't do anything to change that. We can't even temporarily change local weather.
2 million years ago, Florida was 3 times the size it is today. Sea level was MUCH lower. When Florida was settled 10,000 years ago, sea level was 80 feet lower than now (end of last ice age). The phosphate in Florida is from sea-life that lived when all but the central highlands was under water. That was 10-15 million years ago and sea level was 150 feet higher than now (hot age!)
1,000 years ago the Vikings farmed Greenland during the Medieval Warm Period (MWP). It truly was "green" and much warmer then. (although the Vikings didn't drive SUVs).
Few people know that it takes 50 Million years for a photon created in the center of the sun to reach the sun's surface! (More know it takes only about 8 minutes from the sun's surface to earth.) How can you expect the general population to understand that the sun's output is not constant but varies over both short (11 year) and long (several million year) cycles!
We are actually in a cooling cycle now, so expect temperature to drop over the next 10 to 50 years no matter what people do.
_______________
To re-clarify (and re-affirm) the "global cooling" consensus of only 20 years ago... check out the Newsweek article of April 28th 1975 on the last source below. No, the "global warming" hysteria began in 1997. There was no concern for "global warming" before then, only concern over the devastating effects of "global cooling".

Global warming is undeniable. It's been an accepted fact within the scientific community for over 100 years and known about but not quite understood for another 100 years on top of that.
We have very precise records which show how much the world is warming (and sometimes cooling). The overall trend is one of warming and in recent years it's been accelerating.
There is natural warming and cooling but even the most rapid natural warming, such as that which was witnessed between 10,500 and 18,000 years ago, is very small in comparison to what we've seen over the last 200 years.
From my own peer reviewed and published research temperatures over the last 25 years have ben rising at 31.2 times the rate at which they've risen naturally since the onset of the last warming phase.
---------------
Just to clarify a couple of points from the above answer. Greenland was never green. this was a piece of Viking propoganda orchestrated by Eirik Raude (Eric the Red) to lure the Icelandic people to his new settlement, in his own words "people would be attracted to go there if it had a favourable name". In fact, there were only two places where crops could be grown and then, only during the short summer months. The rest was a frozen wasteland.
Solar variation over short periods of time is minute, the difference between minimum and maximum output during a full sun spot cycle is a little less than 0.1% (1.3 from 1366 W/m²/yr). A deviation over many years can add up but the deviation from year to year is much smaller than the cyclical variation range, more like 0.001%).
Heat from solar radiation attributable to solar variation has increased by approximately 0.3W/m²/yr since 1750, anthropogenic global warming has contributed a further 2.4 W/m²/yr. In percentage terms human have contributed 89%.
Further, we're not in a cooling cycle now unless you look at the much larger picture stretching back to the onset of the last ice age a little over 50 million years (technically we're still in the same ice age now). Recently temperatures have been higher than at any time since humans appeared on Earth (not the highest ever, they've been considerably warmer on four occasions dating back through the 542 million years for which we have climate data) and all of the hottest years on record have occured recently. 2006 being the hottest year and 2007 on track to break the record (despite snow and ice in much of the US - globally temps are considerably above average).

Since average temperatures are dropping around the world, I'd say its turned to global cooling again.

Real and mostly caused by us. Reasons:
This is science. Opinions don't prove anything. "logical" arguments don't prove anything. The data is what's important and the scientific data says global warming is happening and it's mostly caused by us.
Very short version:
http://en.wikipedia.org/wiki/Image:Climate_Change_Attribution.png
The best summary of the data available:
http://www.ipcc.ch/SPM2feb07.pdf
Scientists have seen much stranger things than global warming (like Einstein's relativity or quantum mechanics) proved to be true by data. So the data, not "logical" arguments, is what they go by. The data is why why the vast majority of scientists agree that it's real and mostly caused by us. Data about that here:
http://www.sciencemag.org/cgi/content/full/306/5702/1686

there is a lot of evidence of man made climate change .and there are many reasons to hide the truth
scientists who work for politicians ,get paid by these politicians and they have downplayed the facts because solutions are expensive and means change and change effects many peoples incomes,and upsets profit margins,so most of the world is kept in the dark of the real things that are going on.for political and economic reasons
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 no 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.
Africa and Asia are loosing millions of people to AIDS , many of whom were food producers.
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

I"m freezing at my house in the south this late in the year. It was warm in Jan. It's weather. It's gets hotter, it's gets colder but my car had nothing to do with it. I tell you one thing I believe is that you can't change the weather no mater what you do!

Yeah. As far as people who don't believe in it go.. what's so bad about finding more environment-friendly fuel and energy sources? The economy will survive.
