Global warming statistics
June 25th, 2009
Global warming has been a hot subject in today’s environmental issues because of its effect on the climate, which drastically changed in the past years. Hot summers become hotter and cold winter has not been cooler. Global warming occurs when there is an average increase in the Earth’s temperature. Studies show that the earth is getting warmer by 1 degrees farenheit over the last 100 years. The climate and health effects of global warming in general has caused the subject to be an interesting study nowadays.
A government panel called Intergovernmental Panel on Climate Change (IPCC) released its fourth assessment report on the climate change in 2007. This organization was estbalished by United Nations Environmental Programme and UN’s World Meteorological Organization (WMO) since 1988. The panel is composed of members of the UN and WMO.
The fourth assessment report in 2007 showed that the the earth has indeed warmed since the 20th century and that this observation is unequivocal. It also concluded that the average increase in temprature was due to the greenhouse gas concentration in the atmosphere which keeps the earth’s surface warmer. Other observations include the earth atmospheric composition, the earth’s average temperature, conditions of the ocean and other changes in the climate.
Based on the report, one of the indications that the earth has warmed is that there was lesser cold night and winters. In fact, the years between 1995 and 2006 was the warmest year. An average temperature of 0.74 degrees Celsius has caused this warming effect and that a metropolitan area or what we call the urban heat island has not been counted to these effects. It has also been observed that 80% of the heat has been absorbed by the ocean which cause the change in the climate system. Furthermore, snow and glaciers in the north and south hemisphere have decreased in volume as well as the ice sheets in the arctic. This causes the rise on the sea level by about 3.1mm yearly since 1993 to 2003. However, anartic sea ice has not increase its sea level since there was no observed warming in that area. There was also increase in hurricane activities especially in North Atlantic although there was no specifications on how many hurricanes are expected but this increase is related to the rise in the temperature of the sea surface.
The observations from this report is somewhat subject to criticism due to some political issues.There are also scientific and non scientific arguments that can be derived from this. However, these are panels composed of scientists and authors that agree on issues related to climate change and has been a reliable source of review.
Global warming facts
June 24th, 2009
Global warming or what scientists popularly call them as climate change has taken its toll. Vice president Al Gore, has expressed his views on the dangers of these natural threat to the living creatures on this planet Earth. It may not be directly felt at this time but the danger may be faced by the next generations to come.
This phenomenon is causing a lot of changes to the globe’s climate, distorted weather patterns which has become unpredictable over the years, increase of vector-borne diseases, and leading to animal extinctions.
The changes in earth’s climate can be best described as the imbalance in the greenhouse effect. Greenhouse effect basically pertains to an occurrence in the Earth’s atmosphere which traps the heat from escaping but in turn maintains the earth’s temperature to provide a certain amount of heat for the living things to thrive- the rest of the heat escapes into space. The danger comes when more of the greenhouse gases are in the atmosphere. When more heat gets trapped, it increases the intensity of the temperature leading to unimaginable disturbance in the natural cycle.
Global warming is both caused by natural cycle of the earth’s activities and human undertakings. Most scientists and researchers believe that the main cause of global warming is due to an increased emission of greenhouse gases from different activities.
Not all greenhouse gases have similar heat-trapping abilities. Some of them can trap more heat than carbon dioxide. A molecule of methane can trap heat 20 times more than a molecule of CO2. Nitrous oxide has 300 times more heat trapping property than CO2. Other gases, such as chlorofluorocarbons, have heat-trapping potential thousands of times greater than CO2. But because the concentrations of these gases are much lower than CO2, not one of them has the potential to add as much warmth to earth’s atmosphere as CO2 does.
It has been noted that the United States is responsible for the highest amount of cumulative CO2 emissions which amounts to about 30% even up to today and continues to increase emitting the greenhouse gas by 20%. China, however, is expected to compete or even overtake the US in the next decades with their increasing industrial activities.
It may take over a decade to allow the carbon dioxide to disappear in the Earth’s atmosphere. But even if carbon dioxide emissions cease immediately overnight, still past irresponsible actions would still affect the planets in years to come, affecting future generations.
Unfortunately, the World Health Organization blames the 150,000 deaths in a certain period of time, to the effects of global warming- the extreme and predictable weather in selected places, longer droughts, extreme heat waves, decreased food production, and spread of malaria, a vector-borne disease.
Bang for the cluck: Turning chicken feathers into car fuel and more

If there is any more worthless waste product than the four billion pounds of chicken feathers produced by our enormous appetite for poultry products, I don’t know what it is. It would be great if we could stuff them into pillows, but down comes from geese.
Believe it or not, we turn feathers into low-grade animal feed by mixing them with water in a giant and inefficient pressure cooker. Scientist Walter Schmidt of the Agricultural Research Service in Maryland thinks he can make paper, cloth, plant pots, and, yes, auto parts out of them, but it might take a while. Australian researchers want to wear chicken feathers, making them into high-tech sweat pants.
The keratin fiber in chicken feathers is even stronger and more absorbent than wood, and it breaks down in landfills far faster than does plastic or Styrofoam. Finding novel uses for chicken feathers is a pet project of Professor Richard P. Wool of the chemical engineering department of the University of Delaware. He had a very original idea: Why not use carbonized chicken feathers – which resemble highly versatile (and tiny) carbon nanotubes – to store hydrogen for fuel-cell vehicles. Picture very tiny natural sponges, which have a big weight advantage over metal hydride storage of this useful element. How great is that?
Wood enlisted Turkish-born graduate student Erman Senöz in the project, whose results were announced this morning at a conference in College Park, Maryland. We started three years ago, Senöz said. The pyrolysis process – very high heat without combustion in the absence of oxygen – yields fibers that are micro-porous, very thin and hollow inside like carbon nanotubes. They start forming at 350 degrees Centigrade, and above 500 C they collapse. We’re trying to find the perfect temperature.
By the way, the fiber is from the central quill part, so the fluffy feathers are still available to force-feed livestock. Feather fiber is, of course, very cheap, and the gas tank equivalent would be too, costing only about $200. A carbon nanotube tank? How about $5.5 million. Metal hydride tanks, Wool says, are probably $30,000.
This process is not near commercialization, and hydrogen’s extremely low density is a big issue. Wool says that, using the team’s technology, a car would need a 75-gallon chicken tank to go 300 miles in a car. They’re working on it. And the poultry-minded scientists also think they can make bio-based computer circuit boards and hurricane-resistant roofing from the same chicken fibers.
I love the idea of recovering stuff we usually dump into landfills. And since we produce billions of pounds annually, this is one waste stream that really needs to get diverted.

Global warming articles

The earth has certainly been hot these days. It was really observed as such since there was fire and dust which made the skies of Indonesia turn orange because of drought. It was really so as different hurricanes and tsunami hit the different part of USA and even on the other part of Asia. Also, there are real observations on the size of the ice in the Arctic and Antarctic has been recorded and this has supported the real effect of earth’s warming. Natural disasters have truly been a part of the problems in most countries. Nowadays, this has become more common and evident in international news as before. This is truly the result of global warming.
The subject has been around even before the 20th century. But it has become more clear that the earth truly has been sick since then and scientists have been trying to get the attention of the government and individuals since then. With the result on heat waves, floods, forest fires, and melting glaciers, the climate becomes unhealthy as well.
Before, environmentalists and the government has been bombarding what facts and myths are about this phenomena but now these has remained to be real in everyone’s eyes. The debate about global warming has indeed stopped. All agreed that human factors have contributed to the abnormal climate changes. All sectors of the community have been encouraged to be involved to stop and resolve the obvious effect of the warming. Articles are being cited, researches supported and awareness are highly increased on the subject.
Everybody is now aware of the situation. The release of CO2 in the atmosphere will frighten a responsible citizen as the “last part per million of greenhouse gas behaves like the 212th degree Fahrenheit that turns a pot of hot water into a plume of billowing steam”. A melt in the Greenland ice will give an impression we are not only soaking in the melted water but actually unload a much bigger glacier. The latest assessment shows indeed that several ice sheets have doubled rate of slide. The sea level, thus, will continue to rise. This rise concerns on health and animal extinction. If these possibilities will happen, what will become of us? Further misbalance of nature is expected.
It is indeed up to us now to control more natural disaster. Now that we know that nature give back only what we give to it.
