Recommended: Impact of greenhouse effect

To attain a good understanding of the important aspects of atmospheric carbon pollution, it helps to separate the science from the politics, rhetoric and spin surrounding the climate change debate. Fossil emissions account for 8.5 gigatonnes of carbon per annum and the total amount of carbon in the atmosphere is in the order of 800-850 gt. The present latest reading for carbon concentration is 385-400 ppm as compared to the pre-industrial [ approx. 1800 ] level of 280 ppm, however 60% of the increase has occurred since 1960.
The rise in temperature attributed to the greenhouse effect since preindustrial times is 0.8-1.2 C [ degrees centigrade ] with another 0.5 C factored to rise within the next two decades. Many scientists and governments …show more content…

The rocks and sand became very hot from hours of the sun 's rays however the vegetation remained bland and cool, even though the total amount received by each comparable area was equal. The land mass heats at twice the rate of the oceans, due to their increased capacity to absorb the sun 's infra-red rays and to the cooling effect of evaporation.
The other main clue that the greenhouse gases are not the major cause of global warming lies in the science itself, particularly the relative concentration of atmospheric gases comprising largely 78% N, 21% O, 0.9% Argon & 0.03% CO2. Atmospheric C02 accounts for only 10-25 % of the greenhouse effect, methane 5-10 %, ozone 3-7%, however water vapour accounts for a much higher 35-70 %. Also the amount of water vapour in the atmosphere before the wide-spread clearing of forests, one could logically deduce would have been much higher due to the extra transpiration of water vapour through the …show more content…

Previously the abundant forests were sufficient to buffer this effect however with the large scale clearing of lands throughout the 1900 's and particularly since 1950 this has diminished. This has also paralleled the rise in C02 emissions from industry and may be the reason that it has merely been overlooked. Scientists have focused, as would be expected, on the finer details at the molecular level of the greenhouse effect of global warming and have missed the 'bigger picture ' effects of the earth being heated by the sun 's infra-red rays with each rotation around it 's axis every 24 hours throughout it 's 12 month orbit around the

Greenhouse gases are those that absorb and emit infrared radiation in the atmosphere. The most abundant greenhouse gases in Earth 's atmosphere are: Carbon dioxide, Methane, Nitrous oxide ,Ozone ,Chlorofluorocarbons (CFCs). Human activities also contribute to climate change by the amounts of greenhouse gases, aerosols (small particles). The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas in the atmosphere.

B. Thesis: The causes of global warming and climate change are because of increased emissions of greenhouse gases, and the effects of this are rising temperatures and more severe natural disasters. II. Body A. Counter Claim: Most scientist and people believe that humans are the cause of global warming because of the emissions that they put into the air, but there is a small percentage of people who think that global warming is not caused by emissions at all.

Climate Change This quote said by Washington State Governor, Jay Inslee shows the severity of climate change “We are the first generation to feel the sting of climate change, and we are the last generation that can do something about it.” “On Earth human activities are changing the natural greenhouse of the Earth.” (A blanket around the Earth). Burning fossil fuels is causing carbon dioxide to be released into the air.

Global warming is all about adverse climate change caused by the trapping of greenhouse gases in the earth's atmosphere that affects biodiversity and poses a serious health hazard. Scientists have found strong evidence that human activities have caused most of the warming since the mid-1900 (“global warming”). Humans are responsible for

Deforestation: Good or Bad? By Tristan McDermott (Final Copy) Deforestation is a controversial environmental issue, with some people believing that it is necessary to cut down trees to make room for things such as buildings and roads, while others believe that it is bad because it is destroying the environment. I believe that deforestation, while it does have a few positive effects, mainly has negative effects that massively outweigh the positive effects. According to an article written by National Geographic, (https://www.nationalgeographic.com/environment/global-warming/deforestation/) deforestation is a major contributor to global warming: “Trees also play a critical role in absorbing the greenhouse gases that fuel global warming.

Many scientists believe that our production of carbon dioxide and other greenhouse gases is having a heat effect on the atmosphere and this could be dangerous for the environment and human life (Hansen, 2011). This article will examine the causes of global warming, its impacts and the remedies we can do to combat global warming. Many problems could result from global warming. Increase

1. Introduction: Carbon dioxide (CO2) is one of the important green house gases (GHGs) emitted in the atmosphere through various human and natural activities. The human activities include rapid industrialization and urbanization, deforestation, excessive use of fertilizers in agriculture, excessive use of fuels, papers and many other manmade resources whereas natural activities include volcano eruption, forest fires, earthquakes etc. Emission of GHGs in the atmosphere leads to global warming which is one of the primary reasons behind the atmospheric changes that affect the human life directly or indirectly. The consequences of global warming are extremely harsh seasons, untimely rains, extended summers and floods that results in human deaths, destruction of flora and fauna in addition to the huge economical losses.

Arguably the most significant thing humans have done to cause climate change is the drastic increase in CO2. As a result of human activities, carbon dioxide, methane, nitrous oxide, and the halocarbons (a group of gases containing fluorine, chlorine, and bromine) build up in the atmosphere over time, as well as the natural sources of CO2, like vegetation. The concentration ofCO2 has went from 280 to more than 380 parts per million in just two hundred years. Still currently rising, the burning of fossil fuels by humans will continue to cause global warming and climate

With deforestation being one of these roles because when we chop down these trees and plants of where animals habitats our it also releases a lot of carbon dioxide into the air. And if you didn’t know forests are major carbon storage centers, when deforestation happens all the carbon dioxide that is stored in these forests; is released back into the atmosphere. Deforestation not only contributes to changes in the climate, it also causes localized changes in the weather. Trees transpire, or release water into the atmosphere, during photosynthesis. This water replenishes clouds and maintains rainfall.

Perhaps less obvious but no less ominous a threat to the environment are the general increase in temperatures worldwide and the resulting climate changes. This phenomenon, known as global warming, could have serious negative effects on humans and all other living things on Earth. Global warming is a complex problem, and governments have had great difficulty deciding how to address it. Some people think that it is the work of the world where nothing we do can ether change it or anything we do will prevent it. While others say that the

These factors combined will probably further exacerbate climate change. As soon as the average temperatures are higher than 2C relative to pre-industrial levels, irreversible effects that presumably reinforce themselves will manifest (IPCC, 2014). Moreover, some researches even argue that a cap at 2C might be overly benevolent and would not prevent severe detrimental consequences (Hansen et al.,
