Introduction
Over the past 100 years, the earth has warmed by about 1ºF.the reason as to why and how has not been concluded scientifically as the scientists themselves seem not to be exactly sure. Some are of the view that the earth could be getting warmer on its own, with others, the majority being of the world’s leading climate scientists asserting that things people do contribute to earth warming (Peito and Hartzel, 2000). Scientists worldwide are aware that greenhouse gases make warms the earth by trapping energy in the atmosphere hence they the effects of these gases. With climatic change
Global warming
Global warming connotes a typical increase in the Earth’s temperature, culminating in climatic changes (John H, 1997). Warmth in the earth can lead to changes in rainfall patterns, an increase in sea level, as well as a wide range of impacts on plants, wildlife, and humans. When scientists talk about the issue of climate change, their concern is based on global warming caused by human activities.
Global warming as it is thought it exists, it does not exist. And believe it or not, Global Warming if it does, it is not due to the human contribution of Carbon Dioxide (CO2). This brings us to the greatest deception in the history of science (Peito and Hartzel, 2000). And people waste time, energy, and trillions of dollars while generating needless fear and anxiety over an issue with no scientific explanation. For instance, Environment Canada boasts about using $3.7 billion in the last five years trying to resolve the climatic change almost all on propaganda attempting to defend a defenseless scientific position whereas ironically closing weather stations and faulting to meet legislated pollution targets.
I am not denying that global warming has happened. The hard fact is that the world has warmed since 1680, the depths of a relatively cool epoch known as the Little Ice Age (LIA) that has generally persisted to the present. I would overtly suggest that these climate changes are well within natural variability and which can be explained quite easily by engaging with other natural phenomena such as changes in the sun. But there is nothing unusual going on (George P, 1998).
The presumption of Global Warming presupposes that CO2 is an atmospheric greenhouse gas and as it raises temperatures inversely increase (John H, 1997). It is on this basis that it was theorized that since humans were generating more CO2 than before, the temperature would certainly increase. The theory seems to have been accepted before testing had started.
I would personally argue that “the compromise was arrived at before the research had even been carried out.” and in the meantime, any scientist who attempts to question the existing wisdom is marginalized and referred to as a skeptic, when in fact he is are simply being good scientists (Thomas G, 1998). This has indeed climaxed with the normal scientific method is effectively thwarted.
It is no wonder that politicians have been drawn into the debate. Politicians are being listened to, whilst a good number of them have no knowledge or understanding of science, especially the science of climate and climatic changes (Thomas G, 1998). Hence, they are not well equipped to question a policy on climate change when it threatens the entire planet. Furthermore, the use of fear and generation of hysteria makes it very difficult to make calm rational decisions about issues requiring attention.
Scientists largely believe carbon dioxide and other air pollution that is collecting in the atmosphere like a thickening blanket, traps the sun’s heat and hence causes planet earth to warm up. It is argued that coal-burning power plants in the U.S. play a significant role in carbon dioxide pollution – it is estimated that they emit 2.5 billion tons every year. Automobiles are considered, the second-largest source, producing nearly 1.5 billion tons of CO2 annually.
Scientist’s version of effects of warming the earth
It is acknowledged that global warming is the one causing havoc in various parts of the United States. In 2002, Colorado, Arizona, and Oregon suffered their worst wildfire period ever. Within the same year, drought created severe dust storms in Montana, Colorado, and Kansas, with floods causing hundreds of millions of dollars in damage in Texas, Montana, and North Dakota. Within sixty years the world has witnessed snow-capped mountains thawing and shortened winter seasons in some seasons such as the Cascade Range in Oregon and Washington.
Outside the American region, extreme heatwaves are marked to have occasioned more than 20,000 deaths in Europe and more than 1,500 deaths in India. This leads scientists to regard this as an alarming precursor of events to come, with the Arctic’s perennial polar ice cap waning at the rate of 9 percent per decade.
Scientists associate Global warming with hurricanes. Here it is safe to admit that global warming doesn’t produce hurricanes; however, it does make them stronger and more dangerous. Because in the event the ocean gets warmer, tropical storms pick up more energy and become more powerful. The net effect is that global warming can turn, a category 3 storm into a much more dangerous category 4 storm.
Even though global warming is an intricate phenomenon, with full-scale impacts hard to predict far in advance, every year scientists find out more about how global warming is affecting the planet, and many agree that certain consequences are possible to take place if current trends continue (Thomas G, 1998). They put forth that, melting glaciers, early snowmelt, and severe droughts will cause more dramatic water shortages in the world, presume that the rising sea levels may promulgate coastal flooding specifically on the Eastern seaboard, in Florida, and other areas, such as the Gulf of Mexico, increased hurricanes as a result of warmer sea surface temperatures, as well as disruption of habitats which can adversely drive many plant and animal species to extermination.
Cutting global warming pollution
It is suggested that global warming can be cut reducing pollution from vehicles and power plants. This calls upon putting the existing technologies for constructing cleaner cars and extra modern electricity generators into widespread use, as well as increasing our reliance on renewable energy sources such as wind, sun, and geothermal.
Conclusion
The rationale I hold is that there is no significant association between CO2 levels and Earth’s temperature over this [geologic] epoch (Peterson T.C & Vose R.S 1997). when CO2 levels were over ten times higher than they are presently, about 450 million years ago, the earth was in the depths of the absolute coldest period in the last half-billion years. Considering the basis of these facts, how can one argue that the recent relatively small increase in CO2 levels is the major cause of the past century’s modest warming.
Concerning Gore’s spectacular display of Antarctic glaciers, breaking up entering the sea. Breaking glacier walls has been explained to be due to the normal advance of a glacier (Peterson T.C & Vose R.S 1997). With low temperatures found in Antarctica, they forbid the melting of the ice front, so if the ice is grounded, the results are that it breaks off in beautiful ice cascades. If the water is deep enough icebergs will form (Thomas G, 1998). Geographers also point out that the temperature rise in this part of Antarctica is probably a result of a small change in the position of the low-pressure systems.
Gore tells us in his material, “Starting in 1970, there was a precipitous drop-off in the amount and extent and thickness of the Arctic ice cap.” This has been held not to be true as there has been some reduction in ice depth in the Canadian Arctic over the past 30 years but no thaw down (Peito and Hartzel, 2000). The Canadian Ice Service reports indicate that from 1971-1981 there was average, to above average, ice profundity (Peterson T.C & Vose R.S 1997). In the years 1981-1982, there was a sharp decline of 15% but there was a quick recovery to average, to slightly above average, as per values from 1983-1995. A sharp drop of 30% occurred again 1996-1998 and since then there has been a steady increase to reach near-normal conditions since 2001.
Gore points out that 200 cities and towns in the American West set all-time high-temperature records. This wantonly misleading as the actual data indicates that overall, recent temperatures in the U.S. are not unusual (Peito and Hartzel, 2000). These indicators and many others leave one convicted that global is otherwise a hoax.
