Global Warming: Natural Or Man Made?

1463 words - 6 pages

Man made global warming has been a topic of uncontrollable controversy for many decades now. Global warming is the increase in the average global surface temperature in the Earth’s atmosphere. There are many theories as to why there has been such a drastic change in the Earth’s atmosphere throughout the years. These theories have ignited many debates amongst scientists. According to multiple scientists, humans are the ones responsible for the alarming change in the Earth’s atmospheric temperature. Theses scientists also fear that human activity will have long consequential problems for the world. Bill Nye, the science guy, is one of those scientists that believes humans are at fault for the increased temperature of the Earth. On the other side of the argument lie a numerous amount of skeptics who are not convinced that human activity is the cause of global warming. Marc Morano is one of those skeptics that opposes the concept of man made global warming. He is the publisher of “ClimateDepot.com” in which he explains why he believes that humans are not at fault. Marc Morano believes that the warming of the Earth’s atmosphere is just part of Earth’s natural weather cycle and nothing more. To him, the increasing rate of Carbon dioxide in the atmosphere does not affect the climate of the Earth. I agree with Bill nye, the science guy, and his theories about human activity causing global warming.
Decades ago scientists did not know wether the Earth’s atmosphere was cooling down or getting warmer. For many years it was hard to tell in what direction the climate was headed. It was not until 1975 that highly sophisticated computer models were predicting that the temperature would increase by roughly 5 degrees fahrenheit or 2.8 degrees celsius. Many other professionals believe so as well. According to Tim Flannery, a well renown author, the doubling of carbon dioxide gas in the atmosphere would lead to a drastic increase in global temperature. “Air pollution is causing a hefty share of global warming” (Tim Flannery “The History of Climate Change”). Carbon dioxide can be produced by respiration or decomposition of organic matter. It is of vital importance to the Earth: It helps regulate the air and water temperatures of our planet. Carbon dioxide is very crucial to for the survival of our planet. All plants use Carbon dioxide during a process called photosynthesis. Plants are important to our planet because they produce Oxygen, which we need in order to survive. Although Carbon dioxide is of much importance to our planet, it is not a good thing for CO2 levels to be very high. When Carbon dioxide levels are too high it can cause what is known as the Greenhouse effect.
The Greenhouse effect can be very dangerous to our planet. What that Greenhouse effect does is it causes the Earth to retain heat: therefore producing high global temperatures. Greenhouse gasses consist of Water vapor, CO2, and Methane. Having high amounts of Carbon dioxide in the atmosphere...

The Natural Causes of Global Warming

1130 words - 5 pages experienced warming throughout the last century is not proof that the industrialization of humans was the cause. If we want to even try to predict what the climate will do in the future, we must look back over a longer time interval. The recent global warming is not a result of human activity, but of natural causes. 97 percent of carbon dioxide in the earth's atmosphere comes from nature, not from man. Volcanoes, swamps, rice paddies, fallen

Global Warming: Human Activity vs. Natural Cycles

1225 words - 5 pages controversial topic, though most of the scientific community can recognize the existence of global warming. Many often question if this effect on the environment is caused by human activity or natural cycles. About 95 percent of scientific studies prove that global warming is essentially caused by man. Although among scientists there is a consensus, all people do not believe it to be true that society contributes to global warming by enforcing the use of

Global Warming and Natural Oceanic Conditions

1367 words - 6 pages Coral reefs face considerable threats and impacts caused by global warming and local effects that alter the natural oceanic conditions, warned Eric Jordan Dahlgreen, of the Institute of marine sciences and Limnology (ICMyL) of the UNAM. Depending on the region of the planet, the hazards to organisms that make up coral communities change in relative importance. However, regardless of the cause, if the conditions are drastically transformed, the

Global Climate Change is Man-made

956 words - 4 pages Whether human beings are responsible for the global climate change has been debated for decades. The climate change is the long-term change of weather in decades to millions of years. Some people argued that the global climate change is part of the natural climate cycle of the Earth or is caused by the radiation and heat from the sun. However, United Nations has claimed that “Human influence has been detected in warming of the atmosphere and

Subsidizing insurance in disaster prone areas or target populations is feasible solution to this issue. The rationale from the consumer's side for not buying insurance against catastrophic loss is its extremely low probability. A policy of social insurance from the government's side could potentially provide an incentive to the consumers for

Global Warming: Fiction or Truth?

1556 words - 6 pages True or false; global warming is a catastrophic event that is occurring by natural and human means that is causing global temperature to rise and that can lead to many disasters? This has been an issue that hundreds and maybe thousands of scientists and citizens have debated about back and forth. The thought of global warming existing is a strong claim that many and most people have been backing up. Reliable sources have claims and evidence that

Global Warming: Fact or Fiction

1503 words - 6 pages present, 98% of total global greenhouse gas emissions are natural. Only 2% are from man-made sources. Although the climate has warmed slightly in the last 100 years, most of that warming occurred prior to 1940, before the upsurge in greenhouse gas emissions from industrial processes. Actually, according to National Oceanic and Atmospheric Administration Climatologist Thomas Karl, in a paper published in 1989, temperatures have been showing a downward

Global Warming – Myth or Reality
