Fundamental Ways That Could Stop Global Warming

Fundamental Paul Brown Friendswood Ways  Author Nathalie Fiset.

What do you think could come in as more important to our basic human needs such as food, shelter, medicine, education or even the need for affection? There could be one issue that would predetermine everything that will transpire on the planet, and that is the planet’s condition. If the world were on the brink of destruction, saving it would be the priority of every single individual. And save it we must. Although the threat is still not at a life and death level, there is an alarming truth that there are several problems that are now bugging the place that we live in. Say hello to global warming. And try to say bye – stop global warming!

Global warming, which is also known as the greenhouse effect, has been here long before you or anybody else out there existed. It’s been here for thousands of years. And through those thousands of years, the earth’s temperature has increased, and so has the effects of global warming. Time magazine has actually coined this problem as a planetary emergency.

There are major solutions that have been done worldwide to cope, alleviate or altogether stop the effects of this major problem. But among these choices, the obvious choice that the human race is supposed to concentrate on is how to stop global warming. Since we have all contributed to the occurrence of global warming (in our own little ways), then we should also join forces in combating this dilemma.

1. Join organizations that promise to educate you about the effects of global warming and what you can do to put a stop to this problem. Be an activist on this matter. After all, everything begins with you.

2. The next step is to conserve energy. And yes, there are so many ways that an individual can save energy. Let’s list some here: car pooling, turning off appliances that are not in use; unplugging any electronic devices that are not in use; buying energy-efficient lamps; keeping the filters of your air-conditioning unit clean; taking a walk (instead of driving); turn off the faucet when enough water has been consumed; do not use appliances or products that release chlorofluorocarbons into the atmosphere (examples are hairsprays and refrigerators that have CFCs); use EEF appliances; start planting trees, etc. These are basic things that we have learned even from grade school and yet, tend to forget the most.

3. If you are a slave of your profession, then, cut on those work hours to help save energy. For every individual that would cut down an hour from his work, there would be millions worth of energy saved. Learn to maximize your time and to properly manage it. I guess you never imagined before that this could also stop global warming, huh?

4. Recycle. Need we elaborate on that?

5. Use environment-friendly fuels and vehicles. They may be a little bit more expensive but they do not contribute to pollution. Honda was the first to come up with a vehicle that is cell-powered, thus, there are no harmful emissions. If you cannot afford cell-powered vehicles just yet, you can opt for those that can run thirty miles in just a gallon of fuel. This way, carbon monoxide is greatly reduced.

6. If you can, harness the power of the sun, wind and water to generate electricity. There are equipments in the market that can be used to harness solar, wind or geothermal energy. These sources of energy are clean and reusable. If, again, you can’t afford to tap on the power of these sources, then, at least, choose an electric provider that does not pollute the environment by the use of fossil fuels.

7. Insulate your home to prevent excessive use of heaters. During summer, dress lightly to minimize the use of air-conditioning units.

Most people would argue that these, altogether, would not stop global warming. Well, maybe for now that is true. But with the collective efforts of each and everyone in the planet, and if everyone would be disciplined enough to care for environmental issues such as this, then even two degrees off the present global temperature would be such a major feat.

Will Global Warming Cause the Next Ice Age?

Next Paul Brown Friendswood Ice Age by Robert F Allison.

One major problem in the debate over climate change is a general lack of knowledge on the subject. People usually don’t think about where their electricity, gasoline, or toilet paper comes from. Part of this acceptance comes from the way industry separates products from the production process…When we turn on lights in L.A., we don’t see the plants and coal mines that generated the power…Only those paying careful attention make the connections. Another part of the problem is that we are reluctant to question science, which has such prestige that people rarely stop to question who is funding research and whether that could compromise findings. (Gibson 17)

Most people also don’t understand how the theory of global warming works. They think that a really cold winter is evidence that global warming is a myth. However, scientists that support the ideas of global warming are referring to long-term climate change. Climate refers to environmental patterns over a long period of time. Weather refers to short-lived events, and can have isolated extremes. One of the predictions of many scientists is that global warming will cause more extreme weather: hotter summers, longer droughts, colder winters, and stronger storms. According to their theories, Europe could be tossed into another ice age because of global warming, not turned into a tropical paradise. This is because of the effect global warming could have on ocean currents.

Skeptics will often find any opportunity to attack the views of scientists based on some isolated weather event, or the lack of such an event. If the scientists predict increasing frequency and intensity of hurricanes, skeptics will point out that this last hurricane season was extremely mild, with the only intense storms hitting Mexico. Ultra-conservative commentator, Rush Limbaugh, doesn’t just consider global warming to be a myth; he calls it a hoax and a religion. “It’s got salvation, got everything in it. It has the primary ingredient of every religion: faith. Because none of it can be proved” (Limbaugh 4). Limbaugh also takes issue with the use of the word “consensus” by global warming activists, and is right to do so. “Consensus and science-I got blue in the face saying this-don’t and cannot mutually co-exist” (Limbaugh 4). If scientists had reached any sort of consensus, this would be a dead issue. Most scientists agree that the temperature of the earth has been gradually increasing, but that doesn’t mean they agree on the possible causes or consequences.

A survey of more than 530 climate scientists from 27 different countries showed that 82% of the scientists agreed that global warming is occurring. Only 2.6% said they “strongly disagree.” When asked if current scientific knowledge can allow for a reasonable assessment of greenhouse gases, two-thirds of the scientists disagreed with the statement.

The question most people are most keen to ask climate scientists is probably “do you agree or disagree that climate change is mostly the result of anthropogenic (man-made) causes?” Slightly more than half (55.8%) of climate scientists surveyed agreed, 14.2% were unsure, and 30% disagreed. Interestingly, more scientists “strongly disagree” than “strongly agree” that climate change is mostly the result of anthropogenic causes. The survey clearly shows that the debate over why the climate is changing is still underway, with nearly half of climate scientists disagreeing with what is often claimed to be the “consensus” view. (Bast 4)

The study goes on to clarify that the question wasn’t whether humans have any effect on climate, but whether they are mostly to blame. It’s certainly quite possible that humans are having at least some effect on the climate, but nothing can be proven with any certainty.

Some skeptics believe that mankind is too insignificant and could not possibly have so much influence on the environment. S. Fred Singer is a well-known climate change skeptic. He has been trying to gain support for the theory that climate change is a natural, cyclical process. He believes the earth has a 1,500-year cycle of warming and cooling, with minor ice ages interspersed with interglacial periods. Singer claims that his research shows this cycle going back at least one million years, often with abrupt changes. At one time, Greenland was quite green, with crops and livestock farming. Warm waters were abundant with fish and seals. There were two thriving settlements, but they were eventually lost to glaciers, malnutrition, and starvation. Dairy farmers were even forced to eat their cows. This was due to a 1.5 degree Celsius drop in average temperatures between 1100 and 1400. “Denmark would not re-colonize Greenland until 1721, when the Little Ice Age was losing its grip on the huge island. Today, 150 years into the Modern Warming, Greenland has 50,000 people” (Singer xii). Singer believes that these cycles are caused by solar changes, not greenhouse gases.

Global Warming: A Brief Introduction

A Paul Brown Friendswood Introduction by Simon Rosser.

The term Global Warming has been in common usage for some time and usually refers to recent warming of Earth’s atmosphere,which also implies a manmade or human influence.

Earth’s atmosphere comprises many gases: oxygen, nitrogen, carbon dioxide (hereafter abbreviated to CO2) and water vapour, to name a few. These gases are collectively called greenhouse gases and they keep the Earth’s temperature at a comfortable 15°C. Without them Earth would be a freezing -18&degC.

Since pre-industrial times, usually taken to be before 1750, we know from ice-core records that CO2 levels were about 280 ppm,that’s 280 parts of CO2 per million parts of air. As industrialisation got underway humankind started to farm the land more intensely than ever before, which included deforestation for agriculture and settlements. Later – since about 1850 or so – the burning of fossil fuels for energy and transport has added considerably to greenhouse gas levels, particularly CO2.

This has resulted in CO2 levels increasing to about 385 ppm, a rise of about thirty-seven per cent from pre-industrial levels – mainly as a result of burning fossil fuels.

How do we know this?

Well, data from ice-core records that go back at least 650,000 years now show us that CO2 levels have fluctuated naturally during this time between 280 and 300 ppm. CO2 levels have also been measured accurately from the top of Mauna Loa Volcano in Hawaii since 1958, and results show an increase in CO2 levels from 315 ppm to 385 ppm since that time.

Therefore CO2 is now at eighty ppm more than it has been for at least 650,000 years of Earth’s history. It is a known scientific fact that higher levels of greenhouse gases will lead to higher temperatures, which appears to be happening now. The world has warmed by an average of 0.74 degrees during the last 100 years or so. As a result of this warming, polar ice has started to decrease and melt, and so have Earth’s land-based glaciers. This in turn is causing sea levels to rise, which is putting low-lying islands at risk of flooding or total submersion, and will eventually threaten more and more of the world’s coastal cities and regions.

Things may get worse, however, because once Earth’s atmosphere starts to warm, the warming itself may cause further positive feedback mechanisms to kick in. A warmer atmosphere holds more water vapour, which is itself a powerful greenhouse gas. This will in turn cause further warming, and so on.

Melting ice results in more sunlight being absorbed by the surrounding ‘darker’ water and land, and that results in further warming, and more melting ice. Methane deposits currently held in a frozen but stable state under the sea and under the permafrost may be released as the oceans warm and permafrost melts, which will cause further warming. This is very worrying as methane is a potent greenhouse gas and around twenty times more powerful than CO2 when talking about it’s ability to warm the Earth’s atmosphere.

This is global warming in a nut shell, however there are of course far more complex issues involved as global warming will not affect the whole planet in the same way at the same time. Some parts will experience more drought, some parts more rainfall, and some parts more extreme weather such as floods and heatwaves.
