Did We Fix The Ozone Layer?

The ozone hole is a region of the ozone layer that is thinning. This hole is as big as the USA and is located over Antarctica. The depletion of the ozone layer in Antarctic takes place there because of the atmospheric conditions that occurs no other place in the world. Because the temperatures during the winter is extremely low, polar stratospheric clouds form. Polar Stratospheric are located in the stratosphere over Antarctica and the Arctic. They also convert forms of chlorine monoxide which are man-made pollutants that get trapped in these clouds. These clouds account for the deterioration of the ozone around Antarctica and helps in the growth of the ozone hole. The ozone hole is also caused by gases called chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) from cars, etc. Halons (brominated fluorocarbons) also have a major effect of the formation of the hole and they can destroy up to 10 times as much ozone as CFCs can. These gases are found in spray cans, refrigerators, air conditioners, fire extinguishers, etc.

Antarctica is the coldest, driest, and most inhospitable continent on Earth. Yet it is yields some 90 percent of the Earth most precious natural resource: water. But behind this pristine exterior, Antarctica is fighting a losing battle. New data suggests that the continent as a whole is warming at an alarming rate. According to recent studies gathered from Nature Magazine, the western half of the continent is warming five times faster than any other place

The third factor that plays a major role in causing skin cancer is the Ozone layer. It helps protect people from ultraviolet radiation. However, the ozone layer is shrinking and this is due to man-made products like sprays and combustion of cars that are emitted in the atmosphere. This process is allowing more ultraviolet penetration to the earth thus increasing risk of skin cancer (Bair, 1991, P. 367,368). Ultraviolet radiation are the chief causes for skin cancer because the UV radiation

Did you know that with all this talk about global warming, and the disappearing of the ozone layer, the root of the problem is us? Yes, we’re the cause of all those problems. We keep putting something called greenhouse gases into the air. A few greenhouse gases are water vapor, carbon dioxide, and methane. While some climate change is natural, humans need to be careful about greenhouse gases because ecosystems are changing, sea levels are rising, and global average temperature increased by more than 1.3 degrees Fahrenheit over the last century.

How do CFCs or chlorofluorocarbons affect Canada’s Ozone layer. To answer this question we first have to understand chlorofluorocarbons and the earth's ozone layer. Chlorofluorocarbons are chemical compounds made up of three chlorine atoms. One fluorine atom and 1 carbon atom. There were many uses for CFCs ranging from, being used as coolants in refrigerants to propellants for aerosols to being used as solvents for dry cleaning. As CFCs are non- flammable and not very toxic we thought they were a revolutionary compound, but unfortunately CFCs were one of the leading causes for the depletion of our ozone layer. ozone is a type of oxygen, an ozone molecule consists of three oxygen atoms whereas a regular oxygen molecule only consists of two.

Antarctica is essential for science because of its enormous effect on the Earth's climate and ocean systems. The Antarctic is critical our understanding of global climate change. Preserved in its four kilometre-thick ice sheet is a unique record of the

The Ice (snow) in the Arctic is melting faster than usual. Sea levels are raising Increased heat waves.

As most people know there is this layer in the sky called the ozone layer. Its job is to protect us from foreign objects and keep oxygen in. We, humans, have created chemicals that can potentially destroy it forever. Chlorine and bromine atoms both destroy the ozone. One chlorine atom when comes in contact with the ozone can destroy 100,000 ozone

The case for attributing the recent global warming to human activities rests on the following undisputed scientific facts:

This is just an explanation of how Global Warming is becoming about. Scientist are proving and discovering new ways to detect and analyze Global Warming and the effects.

Scientists all over the world have been widely researching to find out ways in which the ozone layer is being destroyed through human actions. The ozone layer is gradually being destroyed by ozone depleting chemicals. These chemicals include chlorofluorocarbons (CFCs), hydroflourocarbons (HFCs), methyl bromide, halons, methyl chloroform and carbon tetrachloride among others (Ryding 173). These chemicals are used locally in coolants, fire extinguishers, solvents, pesticides, aerosol propellants and foaming agents.

Ozone molecules absorb ultraviolet radiation that’s radiated from the Sun and this occurs in the upper atmosphere at where the ozone layer lies. This prevents the majority of ultraviolet radiation emitted from reaching the Earth’s surface which is beneficial for human life as it decreases the risk of skin cancer, damage to the eyes and immune system (Kovats, S. and Menne, M. 2002). Ozone is considered to be a protective layer around the

National Geographic wrote the article “Good Ozone, Bad Ozone”. The article is about how there are both good parts of the ozone layer and some bad parts of the ozone layer. The ozone layer is only good when the gas is high above the ground if it is not then it can be very harmful for us. The bad thing about the ozone layer is it is made up of poisonous gasses. Approximately 90 percent of the earth’s ozone is called the stratosphere. Many scientists believe that ozone layer is being destroyed due to chemicals we use. The National Geographic was motivated to write this article to educate us on how the ozone layer has a good and a bad layer. Even though, the ozone layer is helpful because it protects us from harmful ultraviolet rays. It can be bad when the layer is depleted and

The Ozone is made up of three oxygen molecule joint together by covalent bond (O3) which is mostly found in the stratosphere of the Earth. Although it is a poisonous gas, it is important in many ways for human as well as other aquatic and terrestrial animals. But due to the large emission of the halogens and CFCs ozone is being depleted rapidly (Vermishev and Danilov-Danilyan 360-361). The enormous disadvantage of the ozone layer depletion is the inability of the earth’s atmosphere to filter the UV (Ultra Violate) rays emitted by the sun and actually which has created a various problems such as the negative effects on the terrestrial and aquatic skin.

“When taking the heating of the entire climate system into account, our planet has warmed at a rate equivalent to 4 Hiroshima atomic bomb detonations per second over the past 15 years” (Cook). Our planet is becoming warmer. When scientists add up all the heat warming the land, oceans, atmosphere, ice melting, earth is accumulating heat equivalent to four Hiroshima bombs worth of heat per second. Global warming is a serious issue faced by our world as there has been a significant increase in temperature over the years. But the article published by Dr. Mark Sircus on “Global Warming -largest science scandal in the history” refutes the theory of global warming. Dr. Sircus states that there is no linkage between carbon dioxide and temperature leading to global warming, the sea level is not rising, arctic sea ice extent is now higher and climate change is due to solar activity. Dr. Sircus also points out that that the recent weather changes are not in line with global warming and “we are in the beginning of a deep freeze” (Global Warming - Largest Science Scandal in US History). NASA and the scientific community states that global warming is not a hoax and there is a rapid increase in Earth’s average surface temperature due to greenhouse gases released as people burn fossils. NASA states that the “key indicators of global warming are based on surface, satellite, and ocean temperature measurements, satellite measurements of energy imbalance and of receding glaciers, sea ice, and
