The World Has Got A Problem



The world has got a problem,
That politicians just wont face.
The world has got a problem,
That concerns the human race.
The world has got a problem,
That business men ignore.
The world has got a problem,
That affects us more and more.

We're burning those natural resources,
I tell you that we've got to hold our horses,
Cos we're making too much carbon dioxide,
Thats a waste we just can't hide.
Too much carbon dioxide,
Is a problem spread worldwide,
Too much carbon dioxide,
Will destroy our precious jewell.
Too much carbon dioxide,
Comes from burning fossil fuel.

We've got to leave the coal in the ground,
And let the oil stay where its lying.
Just leave the natural gas where 'ere its found,
Or very soon we'll all be dieing.
We've got to keep the atmosphere really clean,
Or the climate will get deadiy mean,
And life on Earth will end,
You've got to listen to me friend.

Youv'e got to leave the coal right in the ground,
And let the oil stay where its lying.
Just leave the natural gas where 'ere its found,
Or very soon we'll all be dieing.
We've got to keep the atmosphere really clean,
Or the climate will get deadly mean,
And life on Earth will end,
Our selfish ways we now must mend.

We'll soon be reaching Rubicon,
That's the point of no return,
We've got to make our minds up,
A lesson we must learn.
We're acting like a cancer,
We're commiting suicide.
There must be something we should do,
Cos we cannot run and hide.

We've got to leave the coal in the ground,
And let the oil stay where its lying.
Just leave the natural gas where 'ere its found,
Or very soon we'll all be dieing.
We've got to keep the atmosphere really clean,
Or the climate will get deadly mean,
And life on Earth will end,
You've got to listen to me friend.

Youv'e got to leave the coal right in the ground,
And let the oil stay where its lying.
Just leave the natural gas where 'ere its found,
Or very soon we'll all be dieing.
We've got to keep the atmosphere really clean,
Or the climate will get deadly mean,
And life on Earth will End

''Despite what some in the “mainstream” media assert, there is no “debate about global warming not amongst informed scientists, anyways. Scientists knowledgeable about climate change debate only the finer details, such as: how much CO2 increase will double surface temperature (known as the Climate Sensitivity Equilibrium), or, the role of aerosols in slowing or forcing atmospheric warming (seems different aerosols can have different impacts, and depending on where in the stratosphere they reside).

The only “debate” in mainstream society is a pseudo debate between far-right conservatives (and their proxy pundits in the media) who remain in denial about human-caused (or human-accelerated) climate change — despite a growing mountain of supporting evidence — and a shrinking population of hold-out skeptics and those who sadly receive their science news from limited and/or disingenuous sources.'' (source)


Global warming is primarily a problem of too much carbon dioxide (CO2) in the atmosphere which acts as a blanket trapping heat and warming the planet, in turn creating Climate Change. As we burn fossil fuels like coal, oil and natural gas for energy or cut down and burn forests to create pastures and plantations, vastly increased ammounts of carbon accumulate and poison our atmosphere, killing plants-wildlife-agriculture and ourselves, the trapped heat melts our ice caps releasing water and further gasess into the atmosphere, sea levels rise flooding both farming and urban land areas...



Moreover, since the atmosphere is absorbing more energy than before, the increase energy will also make storms more violent, more powerful. This is an application of a very basic laws of physics - the law of conservation of energy. Since the atmosphere has more energy, it will use it. The atmosphere will not simply absorb more energy forever. Think stronger hurricanes, stronger thunderstorms, more windy days, etc on an esclating vortex without end. Venus is a fine example of what happens if the 'Greenhouse Effect' goes too far. Venus is covered in clouds and super hurricane storms hurtling around the planet. Venus' high concentration of 'Greenhouse' gases also absorb infrared radiation well, making the planet very hot.

The Three Stooges Of Climate Change - Ignorance, Avarice and Inertia
 Climate change is also making snowstorms stronger and more frequent - US scientsists have stated ''...as the Earth gets warmer and more mositure gets absorbed into the atmosphere, we are steadily loading the  dice in favour of more extreme storms in all seasons, capable of causing greater impacts on society'' ( source ).

At the same time, because less of a region’s precipitation is falling in light storms and more of it in heavy storms, the risks of drought and wildfire are also greater. Ironically, higher air temperatures tend to produce intense drought periods punctuated by heavy floods, often in the same region. These kinds of disasters may become a normal pattern in our everyday weather as levels of heat-trapping gases in the atmosphere continue to rise.


What would be the effects of an increase of CO2 on agriculture and plant growth in general?  
The following points make it clear;

“Both climate change & climate variability are relevant drivers for plant disease epidemiology” (Maynard et al, 2003).
1. CO2 enhanced plants will need extra water both to maintain their larger growth as well as to compensate for greater moisture evaporation as the heat increases. Where will it come from? Rainwater is not sufficient for current agriculture and the aquifers they rely on are running dry throughout the Earth. On the other hand, as predicted by Global Warming, we are receiving intense storms with increased rain throughout of the world. One would think that this should be good for agriculture. Unfortunately, when rain falls very quickly, it does not have time to soak into the ground. Instead, it builds up above the soil then floods causing damage to the crops. The water also floods into creeks, then rivers, and finally out into the ocean carrying off large amounts of soil and fertilizer.

2. Unlike Nature, modern agriculture does not self fertilize by recycling all dead plants, animals and their waste. Instead we constantly produce artificial fertilizers from natural gas which will eventually start running out. By increasing the need for such fertilizer we shorten the supply of natural gas creating competition between the heating of our homes and the growing of our food. This will drive the prices of both up.

3. Too high a concentration of CO2 causes a reduction of photosynthesis in certain of plants. There is also evidence from the past of major damage to a wide variety of plants species from a sudden rise in CO2. Higher concentrations of CO2 also reduce the nutritional quality of some staples, such as wheat.

4. The worse problem, by far, is that increasing CO2 will increase temperatures
throughout the Earth. This will make deserts and other types of dry land grow. While deserts increase in size, other eco-zones, whether tropical, forest or grassland will try to migrate towards the poles. However, soil conditions will not necessarily favor their growth even at optimum temperatures.....



CO2 Direct Impact on Human Physiology.
Carbon dioxide (CO2) is a gas that's always present in your blood. It is the waste product generated as your body uses up oxygen, and it is expelled from the lungs when you exhale. At normal levels, its presence has no measurable adverse effects on you, but if your breathing is compromised or you are exposed to large amounts of this gas, you can experience a wide range of side effects, some of which include permanent injury and death. 
Respiratory Effects;
Carbon dioxide is known as an asphyxiant, which is a substance that bonds with your blood in place of oxygen. The website eMedMag.com notes that while most simple asphyxiants do not have any inherent toxicity of their own, cases of CO2 poisoning have been linked to central nervous system damage and permanent deterioration of respiratory functions. Because of these findings, CO2 is considered not just a simple asphyxiant, but a gas with acute systemic effects as well. 
Cardiovascular Effects;
If your blood becomes saturated with too much CO2, you develop the condition known as hypercapnia. Symptoms and signs of early hypercapnia include flushed skin, headache, confusion, lethargy, muscle twitches, hand flaps, reduced neural activity, and possibly a raised blood pressure. Increased levels of CO2 also affect the pH level of your blood, turning it more acidic. This condition is called acidemia and, if prolonged, causes acidosis, which is injury to the body's cells by a rise in acidity that leads to faltering functions of the heart. Some possible outcomes of this interference with your heart include low blood pressure and cardiac arrhythmia. 
Nerve Damage;
HealthNewsFlash.com details the levels of damage your central nervous system can experience as a result of high acidity. These conditions are result of temporary or permanent nerve damage brought on by acidemia, including delirium, hallucinations, seizures, respiratory failure, coma or death. 
Asphyxiation;
As an asphyxiant, carbon dioxide displaces breathable oxygen and impairs pulmonary gas exchange. While asphyxiation is commonly associated with choking on a physical object or drowning, you can suffocate on CO2 without any visible abnormality or obstruction of your breathing. If the oxygen content of the air you breathe is insufficient, you slowly suffocate due to selective oxygen depletion until you experience permanent damage or death.

Global Warming of the past 100 or so years has already resulted in:

A. More extreme weather patterns (too hot, cold, dry or wet for some); B. Less predictability
C. Melting of ice in polar regions and the retreat of glaciers in alpine regions;
D. Variable and unpredictable snowfall reductions in areas that have supported winter tourism activities (snowfall in the Alps has halved over past 30 years); Year after year ski rental figures go down as temperatures go up.
E. Desertification (the world’s tropical forests are disappearing at the rate of 13 million hectares a year – that is an amount equivalent to the size of Greece);
F. Unusual flooding and increasing storms.
Until relatively recently (the last 3-5 years), there was no scientific consensus that the planet was warming and that this increase in average temperature was caused by human activity. Now the evidence of warming is indisputable although some still argue that its cause may be more due to natural cycles than human activity. While changes in average temperature have occurred on several occasions in the past, they took place over much longer time frames (from thousands to millions of years) giving species time to evolve and adapt. Meta changes are now occurring within decades. 



An argument, made by those who deny man made Global Warming, is that the Carbon Dioxide that is being released by the burning of fossil fuels is actually good for the environment based on the logic that, if plants need CO2 for their growth, then more of it should be better. However "Too much of a good thing can be a bad thing." For example, if a doctor tells you to take one pill of a certain medicine, taking four is not likely to heal you four times faster , It's more likely to make you sick.

Nuclear's proponents do have a point that nuclear power does not directly emit GHGs. Unfortunately, there are a great number of concerns about nuclear power that should be addressed before it can be classed as a green or safe power source. The uranium/nuclear fuel cycle replaces one emissions problem, GHGs, with another, nuclear wastes. Recalling Murphy's Law-that if anything can go wrong, it will. It is prudent to remember names like Three Mile Island,Chernobyl andf Fukushima Daiichi...

 

Alternative Energy sources include Solar Power, Sea/Wave Power, Wind Power, Passive Heating & Cooling, plus tapping  Geothermal Energy.

ENERGY - Mural by Green-Flower
Many other alternative sources are already widely used. Hydroelectric energy plants generate a significant portion of the world’s power. Other sources, including solar energy and wind power provide a small share of a region’s power but could provide much more. Sources such as tidal power and geothermal heat are site-specific, and of use only in the right location. Some promising technologies, for example the hydrogen fuel cell, remain under development.

Unlike that from fossil fuels, energy from sunlight, wind, water, plants, and geothermal heat does not create extra carbon dioxide, and so does not add to global warming. Best of all, unlike fossil fuels, which will become increasingly scarce, these fuel sources are renewable and will never run out. One day, they may completely replace fossil fuels.
