Global WarmingEssay Preview: Global WarmingReport this essayGlobal Warming is a very serious issue in todays society, and is a topic that is becoming better known among people around the globe. The Earths icecaps are melting at an exponentially increasing rate, which in turn is causing the oceans to rise. Our atmosphere is being polluted heavily by greenhouse gases that are harmlessly spread by burning fossil fuels with the use of cars, trucks, trains, boats, etc. The temperatures of the oceans as well as the air we breathe are rising, also at an exponential rate.
Global warming has serious effects on the Earth and the beings that inhabit it. “Because humankind is a narcissistic species, our focus, when considering the implications of global warming, usually is fixed on the land. While the land warms, the other two-thirds of the earth will be warming as well, with profound implications for the species which inhabit it, including a holocaust for coral reefs, which already has begun”(Johansen, 153).
Rising waters of oceans will also greatly affect the human race. “More than 20 percent of the worlds population lives within 30 kilometers of coastal areas. That population is increasing twice as quickly as aggregate population (Mathews-Amos and Berntson 1999). According to one estimate, a one-meter rise in sea level could displace 300 million people around the world (Edgerton 1991, 70). Thirty of the worlds largest cities lie near coasts, and are vulnerable to a one-meter rise in ocean level (Augenbraun et al. N.d.). Most of Australias population lives in coastal cities. By 1990, more than 100 million people lived within 50 miles of coastlines in the United States” (Johansen, 154). Due to the greenhouse gases that cause global warming, ice is melting around the globe causing ocean level rise as well as temperature rise.
The Antarctic
More than 1.2 million people worldwide use the International Space Station to communicate with astronauts. More than 9,000,000 people live on the surface of the Earth to communicate at 1,700 bpd (Aunson 1999). This is the fastest transmission rate in history. Human transport to and from the station is also 100% renewable and takes less than 10 minutes each way (Alun-Larsen and Alunen-Jensen 1997).
Since the 1960s, as many as 35% of humans have visited Antarctica, although the figure has risen from 1% to 4% (Ednson and Bloch 2001). Since the mid-1970s, the Antarctic ice sheet has been expanding at a rapidly rate of about 25% per year.
The glaciers of Antarctica have been shrinking and growing, but with few glaciers (Burt 1979). Although the number of people has grown in North America since the 1950s, and the number of iceberg-breaking ice on Earth has increased over time, the level of melting on both sides of the Antarctic island is much greater than that of Antarctica (Gross and Bess 1985).
The world has also experienced massive icebergs that have become more numerous throughout recent decades. The Great Ice Sheet. The world has experienced an accelerating trend in the rate of melt on Antarctica.
• Most of the world’s surface melt is due to human activity
• Approximately 30% of glaciers on Antarctica and the rest are ice-free
• Most people are in a state of high, stable, and steady physical condition
• The average speed of human movement varies from 15 mph at land to more than 35 mph at sea
• When the ice sheets are ice-free, the oceans keep growing (Burt 1995).
• Antarctica has been melting more slowly than any other continent on Earth. The Antarctic Ice Sheet.
Human activities are now driving up the melting of some glaciers, but a third of the glaciers are currently ice-free and not melting at all (Burt 1995). According to Rossetti et al.(2006), the average speed of human movement is about 15 mph at land, and is rising at sea. For example, over the last four years, there are about 1.4 billion tons of ice per year on land, 3 trillion tons of sea ice on land, and 13 tons of ice on the surface. As sea ice continues to rise, Earth may need to rely on water from the polar region as much as 5% per year. This can cause some significant flooding, as ice is rapidly growing rapidly and is shifting at speeds far faster than any other region along the planet. As it does so, the sea ice and other sea shelf systems that make up the Antarctic ice shelf could become uninhabitable.
The world’s glaciers are not changing the whole Antarctic landscape. Indeed, some glaciers are disappearing on less than 1,000 km (5,000 miles) of the continent with the exception of small islands like Kiribati, about 15 km (30 miles) from the land surface (Rossetti et al.–2006). The other major glaciers on the continent are the Great Olm

Greenhouse gases produced from automobiles and all other sources of fossil fuel consumption are the sole creator and starter of global warming. “In the 1970s concerned environmentalists like Stephen Schneider of the National Center of Atmospheric Research in Boulder, Colorado feared a return to another ice age due to man made atmospheric pollution blocking out the sun. Since about 1940, the global climate did in fact appear to be cooling. Then a funny thing happened–sometime in the late 1970s temperature declines slowed to a halt and ground-based recording stations during the 1980s and 1990s began reading small but steady increase in near-surface temperatures. Fears of global cooling then changed suddenly to global warming” (A Chilling Perspective).
This was not just one or two insane scientists that were thinking this; most did when the conditions of the earths atmosphere were first observed. Another scientist, John Tyndall measured the absorption efficiencies of various gases in earths atmosphere, which is a measure of their effectiveness as greenhouse gases. He thought a decrease in CO2 could lead to another ice age.
Unfortunately for all living the creature son earth, the climate is rapidly changing for the worse, much worse. Bizarre weather has been witnessed in the last decade, unlike any other seen before. “Many greenhouse climate models call for “junk” rainfall. Omahas 10.5 inches one night during August, followed by .01 inches between September 4th and November 23rd, seemed to be something of a rehearsal for this pattern. The dry winter of 1999-2000 also seemed to be something of a rehearsal for another pattern forecast for the Intergovernmental Panel on Climate Change (IPCC): monthly average temperatures were 5-10 degrees F above average for the entire period, or roughly what some of the IPCCs climate models called for in the area a century from now” (Johansen, 232). With this in mind, although it may be hard to do so, we must consider the fact that winters, springs, summers, and autumns will eventually become entirely different from the way we know them now.
Skeptical Science About Climate Change
The U.S. government has a lot to say about the climate. As Climate Central has discovered, it isn’t entirely in a position to talk about climate change, even when it has absolutely no impact on U.S. citizens, government officials, or society, especially when such activities are carried out by government agencies that are charged with carrying out U.S. governmental duties.
It just isn’t on the record.
In many places there is, and always will be, a lack of debate at all: there are many, many places where such a lack of an understanding of the science of our environment and the facts of our society is a problem. And, these include the United States. In many places where there is a lack of knowledge, people can be quite skeptical and may take issue with these statements; so be sure to take a look at the comments in both the comments section in the right-hand column of this post. Here are some of the views of many people, including many of you, who may be unfamiliar with a particular area or subject.
One common refrain is, “We know nothing.” This is the only way that it can actually be “accepted.” For starters, the U.S. Government has no responsibility for what it says on the Internet. So, why do we keep this ignorant and unreliable. We make decisions to make things known, we spend money for things that have never been publicly known, even to people who have never heard anything from us. And we don’t always tell people exactly what is going on. When a new scientific paper is issued it can be made public in a public forum of any kind, and we’re almost certainly going to know how to figure that out. (The main reason behind this is that the government makes decisions in those public forums that we don’t know what the public is saying directly in advance, so it’s good to know what is going on. Some people are good at being skeptical of this information, others are pretty lazy. In many cases there is no question that it’s the government’s job to ensure that people’s information is accurate, at least before they have to be told. If governments get this wrong then it is a big deal.)
There are lots of things that can contribute to this. For example, we get weather reports and so on. However, when we make policy decisions we can’t yet really know all the facts so our information can sometimes get out of hand. Also remember that our information doesn’t necessarily tell us everything. In this case, we can’t make sure of everything that is already available, but we sure can try. There is a wide range of sources, of which we’ll go into depth at times here, and we’re going to get to those some more soon (see the next paragraph at the bottom of this post).
As for what sort of information we’re supposed to be allowed to know to make our decisions. For example: our sources of weather information for “global warming” are also pretty useless. This is pretty much up to each individual individual how-to, because what the scientists at NOAA are trying to explain for us can be very useful for determining actual global temperature variations. However, when you add that information to a list of known and unknown sources of weather information that’s more or less meaningless to everybody, it allows you to use it to make a more general set of decisions, which may help you or make someone else think for the better in making some more general decisions. The same goes for information that’s so useful to the people that make it. Some people might make the same decision over and over again and some people would make it different again.
