Greenhouse Gases Essay

We've all heard about global warming as well as climate change. Climate Change is the buildup of massive amounts of man made greenhouse gases in the Earth's atmosphere. Causing the Earth's temperature to slowly rise over a long period of time.The amount of carbon dioxide in the air has increased rapidly over the years. Climate Change is a global problem and recently an issue more and more people are paying attention to.

Climate change is a change in the average global or regional weather patterns. Climate changes includes factors such as; temperature, precipitation, humidity, wind and seasons, influenced by oceans, land surfaces and ice sheets. This plays a

Climate change is defined as the change in global or regional climate patterns, which is apparent from the mid to late 20th century onwards. When looking at climate change there is an abundance of evidence that supports that humans are the leading causes of the drastic shift in the weather pattern but there is also a lot of evidence against humans actually causing climate changes. For example, the increasing levels of man made gases that are let into the atmosphere may have created a greenhouse effect, which traps heat and ultimately causes global warming. But there are also many scientists who believe that the earth has always naturally cooled down or warmed up at its own pace.

Climate change can be defined as a significant change in the “average weather” of any given region sustained in the long-term and can be caused by Earth 's dynamic processes, external forces including variations in sunlight intensity, and also by human activities (USEPA, 2014).

NGS integrates greenhouse into other major policy initiatives, such as the Natural Heritage Trust, and launches new measures to increase greenhouse emission reduction activities across the Australian community. It provides the strategic framework for an effective greenhouse response and for meeting current and future international commitments. It will provide a fresh impetus for action by governments, stakeholder groups and the broader community and set directions for that action into the next century.

The UNFCC also defines climate change as “a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over time periods.”

Climate is the average of the weather of a region, and the climate of the Earth is the climate average of all the regions. Based on that, climate change is a change in the average climate of the Earth. According to the NASA, “Some causes of climate change are natural. These include changes in Earth's orbit and in the amount of energy coming from the sun. Ocean changes and volcanic eruptions are also natural causes of climate change”

Climate Change is the significant change in the climate and distribution of weather patterns on Earth ranging from the last decade to millennia earlier.

This article critically examines the ways in which individuals could help reduce the impacts of global warming. The author challenges that every individual could significantly minimise the effects of global warming by adopting to a more responsible lifestyle.

Climate change is the term used to describe the warming of the average surface temperature on earth. Climate change; often referred to as the general term global warming, is a topic that often inspires fierce debate among those on both sides of the issue. One thing those who are pro and those that are con both agree on is that the temperature on earth has increased over the past century by an average of 1.4 degrees. The big debate on the two sides is if the warming temperatures are caused by human activities and if it is not stopped it will have dire consequences (the pro side) or if it is the result of natural causes and the earth’s surface will find ways to adapt such as crops becoming more heat resistant (the con side).

   The United States releases twenty tons of carbon monoxide per person per year. Carbon Monoxide release is a result of burning fossil fuels with an insufficient amount of oxygen that causes the formation of carbon monoxide that pollutes our environment. Everyday fuel is burnt by cars, airplanes, large factories and manufacturing plants. This is causing a very large and deadly problem for our environment. When gases used on earth are released into the atmosphere they act as a blanket and trap radiation that is then redirected to earth. This concept is called the Greenhouse Effect (Bad Greenhouse, 1).

Humans are polluting our atmosphere causing the Greenhouse Effect.  What’s the Greenhouse Effect?  “The Greenhouse Effect can be visualized as follows: imagine that Earth has been encircled by a giant glass sphere.  The heat of the sun penetrates through the glass.  Some of the heat is absorbed by the Earth, and some is radiated back towards space.  The radiated heat reaches the glass sphere and is prevented from dispersing any further”(Global Warming The Facts).  This makes the heat bounce back towards the Earth, which heats it up tremendously.

The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases –– primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed. Although uncertainty exists about exactly how earth’’s climate responds to these gases, global temperatures are rising. Go to the Emissions section for much more on greenhouse gases.

Much like the glass of a greenhouse, gases in our atmosphere sustain life on Earth by trapping the sun 's heat. The Earth’s atmosphere contains several different gases that act like a blanket, keeping the Earth warm. Water vapour and some trace gases like CO2, CH4 (methane), O3 (ozone), N2O (nitrous oxide), are “IR active”, i.e. they absorb heat energy, and stop the warmth from escaping into space. Without the entrapment of heat, the earth’s mean temperature would be -180 C and life, as we know it today, would not be possible. These gases are present in the atmosphere in tiny quantities compared to the amounts of oxygen and nitrogen. But even a small change in the concentration of these gases may create an effect that could change our

Climate change could be described as any process that causes adjustment to climate system be it a volcanic eruption to a change in the solar activity. Today, however, the phrase is most often used as climate change caused by humans. Climate change is also used commonly with another phrase – "global warming" – reflecting scientific observations of strong warming trends over the past century or so. Indicators like rising sea levels, retreating snow cover and glaciers, longer growing seasons and shifting wildlife has alarmed scientific community unanimously agreeing that the earth has warmed in the last century. Experts however are of the opinion that climate change is a more accurate phrase than global warming as the latter is just one component affecting the larger climate systems of the earth.
