Global warming seems to be the "in" thing right now to explain everything going on with the weather.
Too hot?- Global warming!
Too cold?- Global warming!
Flood?- Global warming!
Drought?- Global warming!
Hurricane?- Global warming!
No hurricane?- Global warming!
It's really getting old.

I believe it is a concern - maybe not a real threat at this time.
I believe that our large scale and exponential use of energy and the affect of this use on the environment in the form of pollution and waste heat pollution is not well understood or thought out.

There is a growing noxious ,puss yellow haze ,spreading across the globe, you do not need any scientific investigation to see it or explain what it's source is and our natural instincts should tell us that this phenomena is detrimental to the health of the entire environment and we should be doing more to remedy the situation for our own health and well being on into the future.

I believe it's a total liberal scare tactic. Our planet has always gone in cycles, back to prehistoric times.
If the world is warming, why was it so damn cold in Florida last week????

Well let me tell you something I am not going to spend the time calling you this that insulting you instead I will attempt to prove to you that global warming is real. Not through opinion or news articles, but instead through science! I have taken it from a report I have done a few semesters ago. Please do not plagiarize.
The atmosphere acts as somewhat of a “selectively” permeable membrane due to its thin layer; in other words the atmosphere is penetrable by a quantity of solar radiation. The atmosphere is composed of nitrogen (78.084%), oxygen (20.946%), argon (0.9340%), carbon dioxide (381 parts per million by volume), neon (18.18 ppmv), helium (5.24 ppmv), methane (1.745 ppmv), krypton (1.14 ppmv), and hydrogen (0.55 ppmv).
The sun emits a variety of solar radiation that spans the spectrum of wavelengths. Visible light is between 400nm and to 700nm, infrared radiation between 700nm to 1nm, and ultra violet rays (UV) is between 500nm to 700nm. Basic quantum physics law states that energy of these wavelengths is the result of multiplying Pluck’s constant, h= 6.624 10-34joule-sec by the frequency (v) thus E = h v (frequency is established by multiplying the speed of light, c, by the wavelength, λ). So by mathematically utilizing these equations one can deduce that the shorter the wavelength (λ) the more energy the wavelength contains. Iinfrared radiation, ultra violet rays and visible light are among the shortest of wavelengths.
The atmosphere, in particular the stratosphere which contains the ozone layer repels most solar radiation by reacting with ozone (O3) yielding O2 + O, or simply O3 + UV => O2 + O (this will be discussed in detail later on). But visible light does not fully cooperate with the atmosphere; some visible light does penetrates the atmosphere as due to its enormous energy capacity. This visible light is necessary for life on earth because the dynamics of any ecosystem depend on the process of cycling of nutrients and the flow of energy. Now what happens to the solar radiation, the energy? The first law of thermodynamics, the conservation of energy principle takes control it states that energy can be changed from one state (liquid, solid, gas) to another but it cannot be created nor destroyed and as Albert Einstein proved, energy and matter, are connected ( the atomic bomb being a prime example of this connection).
A vast majority of the solar radiation is then used to accommodate photosynthesis by earth’s plant population (this is the change of state), carbon dioxide + water + light energy => glucose + oxygen + water; these results are an absolute necessity to maintain life on this planet. The remaining sunlight (solar radiation) is remitted into the atmosphere and at this stage is where the problem begins. A common misconception is that CO2 is the problem but this is not so CO2 as mentioned previously is also required for photosynthesis (not to mention plant respiration). The real problem of course is the increasing amount of carbon dioxide; many figures on the interent shows an increasing amount of carbon dioxide in our atmosphere. Carbon dioxide is a green house gas, meaning that it does not allow heat to escape, therefore the solar radiation which was emitted, or reflected by the ocean must pass through this barrier of increasing carbon dioxide (in the troposphere).
Carbon dioxide consists of a carbon atom and two oxygen atoms covalently bonded. Quantum physics dictates that solar radiation heat is not permitted to be absorbed by a molecule unless it is vibrating asymmetrically. In order for the molecule to be vibrating asymmetrically the molecule must contain three atoms. As mentioned previously the atmosphere is composed of nitrogen (N2), oxygen (O2), argon (Ar), carbon dioxide (CO2), neon (Ne), helium (He), methane (CH4), krypton (Kr), and hydrogen (H2). This leaves us with two molecules that contain three atoms: methane and carbon dioxide, being the more abundant molecule (and growing). There was once a balance, the oceans would regulate the amount of carbon dioxide, by reacting to the carbon dioxide to yield carbonic acid (CO2 + H2O => H2CO3 ) but with increasing amounts of CO2 the rate of carbon dioxide conversion is slow in comparison to carbon dioxide production. Therefore, increasing amounts of carbon dioxide results in warmer global temperatures.

Also people speak of this "natural" trend in global temperatures as if the conditions of the past are identical to our modern day. The trend stopped being a trend after the industrial revolution.

Peace
Ive noticed yahoo answers poltical arena has become a battle ground between democrates and conservatives. Why waste your time calling each other this that blah blah why not use reason, facts, investigation, science to make a statement. Remember "Wise men speak because they have something to say: Fools because they have to say something" Plato

Is global warming a man-made menace?
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
some home truths
politicians and scientists who work for politicians have downplayed the facts because solutions are expensive and means change and change effects many people income,and most of the world is kept in the dark of the real things that are going on.
in North Africa,India,Mexico ,millions of people are effected by land loss and desertification
in recent times thousands of people have died because of exessive heat,usually old people.in India ,Mexico and France,
deforestation causing desertification,the desert conditions causing very cold nights and scorching hot days
in china, thousands of what used to be farmers are running for their lives from the dust storms that have burried their towns and turned their lands into dessert,the globe where they were got to hot for them .
and instead of producing food they are now needing it from some where else,and they will drastically effect the world food prices when they start buying water in the form of grains ,at any cost destabalising governments, in some countries ,could be the result
(are you seeing more Chinese around interested in agricultural lands ,we do here in Mexico)
,the Sahara is growing by 7 kilometers a year
and all 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 because of bad farming practices like,over grazing and fertilizers,
as far as the food production is concerned, Global warming or some of its effects are serious,rising seas result in landloss
each degree rise in temperature means 10%crop loss
more landloss because of desertification every year,we have less areble land to produce food ,for an extra 70 million people ,
and there is less and less water (because of deforestation),to irrigate this production ,
and there are less and less farmers to do it..
who are overpumping deep carbon aquifiers
who are plowing more and more unstable lands because they have lost so many million hectares to desertification ,
because of bad farming practises ,such as using fertilizers and heavy machinary or over grazing
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 is in theory reversable,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.
SOLUTIONS
if you want to help the planet ,plant a tree every week ,if everyone on the planet did we we would be able to reverse the destructive processes
reduce carbon emisions,and they are already working on that by alternative forms of energy and regulations on carbon producing materials,aerosol cans,burning rubbish,industrial chimneys,powerplants etc.
the capture of carbon and the production of water and assist the aquiferous manta.
the world bank pays large subsidies for reforrestation to capture carbon and the best tree for this is the Pawlonia
Waterharvesting projects ,such as millions of small dams.to redirect over ground waterflows from the rains into the ground to supply subteranian water supplies.
the protection of existing forrests.
stop building more highways,urban planning to include vegetation stop building cities encourage people to return to the land to conduct their business from there which now has become possible thanks to the internet.
education to motivate people to auto sufficiency by building more home food gardens.
education on environmental awareness
education on family planning to curb over´populaion
Agricultural education and improvements to follow the principals or sustainability and soil management.
more environmental or land ,design to prevent bush fires,such as--fire breaks
,more dams.regulations and control for public behaviour
alternative effeciant public transport to discourage the use of the internal conbustion engine
recicling wastes,limit water use
