Global Warming: Not Our Fault The earth is constantly undergoing changes. This ranges from tectonic activity to atmospheric and climate changes. The most recent change that we have noticed, is the increase in temperature. Some believe that this increase is the result of human activity. However, this is not the case. The increased temperatures are within the normal tolerances from the past few thousand years (Robinson, Robinson, & Soon, 2008). This and other changes to the atmosphere have been going on for millions of years. Global warming is not our fault because it is a natural occurring phenomenon. The increased temperatures are part of a natural cycle that the earth goes through. These cycles include both warming and cooling periods. The most recent warming period was approximately 1000 years ago known as the “Medieval Climate Optimum” (Robinson, Robinson, & Soon, 2008). During the Medieval Climate Optimum the average temperature was much warmer than what is now. 1000 years ago they didn’t burn hydrocarbons like we do now, and the temperatures then were warmer than they are now. 200 - 500 years ago the earth went through a cooling period known as a “Little Ice Age” (Robinson, Robinson, & Soon, 2008). We are currently recovering from that cooling period. During the Little Ice Age temperatures dropped well below average. However, a study of more recent history temperatures can also show that the climates are cyclic and not the result of human activities.
We might disagree on the causes of global warming; however, we cannot ignore that it is happening. Although we still experience cold winters, average global temperatures has risen drastically for the past three decades. Polar ice caps are melting; as a result, sea levels are rising. Scientist predict more extreme weather in the coming decades, in fact, droughts will probably be more common. Also, flooding and tropical temperatures might cause large amounts of methane gases to be released, which could be disastrous for our atmosphere. Climate change may have human causes and also it might be a natural occurrence. Nevertheless, we must find ways to save our planet.
Humans are to blame for global warming, there is no question about it. Humans and human actions are causing a rise in temperature worldwide. We have recorded a steady rise in temperature for the last fifty years. This rise is caused by an estimated 95% of human actions.Humans are to blame for global warming because of deforestation, population growth, and the use of non-environmentally safe products.
These are called warming, or cooling periods. Currently earth is in a warming period, it’s natural. We have had 5 warming periods already and they go way back in time. So far the one we are in right now, is the only one that has involved humans. The evidence in graphs can prove that there has only been one warming period with humans.Our earth didn’t just start changing it’s climate.Climate change has been happening for millions, even billions, of years. It’s not important to us, we shouldn’t be worrying. Even scientists know this, “The world's climate has been changing for the past 20,000 year.” It’s most likely, been happening for even longer than this time. We aren’t the only things that contribute to climate change, theres tons of other things that emit carbon and other gases into the atmosphere..“The change in the orbit affects the heating of the earth... This can last from 10,000 to 100,000 years.” The reason it’s changing the heating is because earths orbit is usually in a circle, but it sometimes changes to an oval like orbit. When the orbit is “Oval like,” it’s closer to the sun. Therefore the earth is heated more, in some spots, when it’s in this orbit. These are some of the simplest reasons to prove my point, but there are plenty out there, look for
Recently, there has been a warmer climate change, causing earth to get warmer, as well as negatively affecting earth, animals, and humans. Since 1880, the average temperature of earth has risen about 0.8 degrees celsius, which is a drastic change, even though it may not seem like much. Also, there has recently been a large amount of greenhouse gases being released, which is a large cause of why earth is getting warmer. Many consequences come with this change in climate. The fast-changing climate on earth has caused countless consequences that could permanently affect the earth.
The human race all around the world wonders if the climate is changing due to human activity or if it is just a natural occurrence. At certain parts of the Earth's surface, the climate can be observed much differently than other locations. As the years go by the average temperature of the Earth increases by little intervals. There are several different reasons why people believe the climate is changing every year. However, the increase of worldwide population and production of heat to the atmosphere is due to the increase of human activities that take place on a daily basis. Human activity is the main cause of the global climate change. The human impact on climate exceeds any known changes due to natural processes. The impact of this human activity is often misunderstood when looking at climate change.
In order to understand the issue of global warming (also referred to as climate change), you must first understand what it means and how it happens. Global warming is a result of a process known as the greenhouse effect, in which the light and heat from the sun are trapped in the Earth’s atmosphere by greenhouse gases; which subsequently raises the average temperature on Earth. The greenhouse gases responsible for this process are carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and tropospheric ozone, all of which are released into the atmosphere through naturally occurring processes (Warrick, R. & Farmer, G., 1990).
Global warming is hot topic nowadays. Alarmists and scientists fight to make their statements known, but while the alarmists avoid the scientist, non-governmental organizations pass themselves as scientist. They not only give out exaggerated data, they also have the nerve to accuse humans of being the cause of global warming. Also, we cannot be certain that we are being told the truth without knowing exactly what is really going on behind the scenes. We blindly trust those in authority because we think that they have our greater good in mind and that whatever they say must be the truth.
On November 8th, American citizens will go to the polls and vote for the next president of the United States. During the presidential campaign, both candidates, Hillary Clinton and Donald Trump, have their own different points of view on environmental issues. Hillary Clinton affirms her commitment to the fight against climate change. She supports the Paris Agreement, which is an agreement among many nations to respond to the threat of global warming and to reverse the worst effects of climate change. Donald Trump, by contrast, does not believe that the shift in the climate is a manmade disaster. He claims that global warming just is a hoax and current global warming is just a part of a natural cycle that is naturally occurring. Donald Trump, then, promises to dismantle the agreement if he becomes the U.S. President. It is important to note that many people and scientists share this same belief with Trump, protesting that global warming is a natural phenomenon. The debate between Hillary Clinton and Donald Trump raises an important issue. Are people primary responsible for global warming? Global warming is due to many reasons; specifically, human activities are the major factors causing the planet to get gradually warmer over time.
The Earth’s temperature has been rising over the years. Sail Bhattacharya a professor & head of a medical college claims that over the last 8000 years, Earth’s surface temperature raised by 1 degree Celsius only (1). He also said, at the present rate of global temperature would rise by 2.5 degrees Celsius by 2050” (1). It’s a fact that the earth has gotten warmer over the years. At this moment the temperature hasn't raised much, only 1 degree Celsius. It may seem like it’s not a big deal, but it actually is, because the rising temperature rate is increasing as time passes according to Sail Bhattacharya (1). The temperature rising might not cause much harm now, but can badly affect us or whoever is living on Earth in the future.
Jessica Ann Olson, argues Al Gore’s points from, An Inconvenient Truth: The Planetary Emergency of Global Warming and What We Can Do about it. Olson plans to use Al Gore’s facts on global warming to support her college essay. Certainty, statistics reflect the impact of our poor choices and the environmental effects.
Earth’s climate system has been experiences changes during the last century. Dating back in 1859 a Swedish scientist named Svante Arrhenius was the first to claim that fossil fuel combustion eventually resulted to the contribution of global warming. According to S.M. Enzler MSc, in his article “History of the Greenhouse Effect and Global Warming”, published by Lenntech, Dr. Arrhenius’ findings were long forgotten, “At that time it was thought than human influences were insignificant compared to natural forces, such as solar activity and ocean circulation. It was also believed that the oceans were such great carbon sinks that they would automatically cancel out our pollution.” (Enzler 1.). Global Warming was just an illusion up until the mid-1900s a scientist named Gilbert Plass began experimenting with carbon dioxide which he soon concluded that adding more carbon dioxide to the atmosphere would intercept infrared radiation, that is otherwise lost to space, thus warming the earth. Dr. Plass’ conclusion is very similar to that of Dr. Arrhenius, and the reason why it was not overlooked was due to the advances in technology during Dr.Plass time, proven to have a more accurate data compared to the past. Further research was conducted to help explain the rise in the global annual mean temperature. As of 1988 it was finally acknowledged that climate was warmer than any period since 1880. I agree that
The global warming is a phenomenon happening all over the earth, there are several causes, but most are a result of human activity. The graph in image 1 shows that a significant increase in the climate temperature in the mid-20th century, somewhere between 1900 and 1950. The industrial revolution happened between the years 1820 and 1840, although great improvements in technology were achieved in the 1900 's. The increasing temperatures since the industrial revolution work as a proof that global warming is a direct effect of human activity. As image 1 shows before the 20th century the variations in the earth 's climate were minimal, except for that of the ice age. Although the industrial revolution detonated the rising temperature due to the use of new chemicals, this change is not evident until it surpasses the previously registered temperatures in the mid-1900 's. Science and technology have improved in the last 200 years, most devices used to measure changes in temperatures were just developed about 150 years ago, so there is not much information of the temperatures before that (Vallis). Nevertheless, scientists have been able to estimate the earth 's temperature from millions of years ago by studding trees, fossils, sediments and water temperatures. Recent studies have proved how many man-made chemicals and activities have contributed to the climate change, affecting the natural processes in the earth like the
The United States Environmental Association (EPA) has listed natural changes in greenhouse gas (GHG) concentrations, volcanic eruptions and solar energy as some of the natural causes of climate changes on earth. However, the recent climate changes cannot be explained by natural causes alone. Research indicates that natural causes are very unlikely to explain most observed warming, especially warming since the mid-20th century. Rather, human activities can very likely explain most of that warming. These human activities are the causes of anthropogenic climate changes. The article also adds “Since the Industrial Revolution began around 1750; human activities have contributed substantially to climate change by the addition of CO2 and other heat-trapping gases to the atmosphere. These greenhouse gas emissions have increased the greenhouse effect has caused Earth’s surface temperature to rise. This is the primary reason which is affecting the amount and rate of climate change is greenhouse gas emissions from the burning of fossil fuels.” Other activities that initiate climate changes are caused by the gas emissions from fossil fuels used to heat homes, petroleum based fuels like gasoline and diesel used for transportation and electricity production which comes from burning fossil fuels.
Researches reveal that natural events as well as human related activities contribute to changes in average global temperatures. AtKisson affirms that global warming is basically a result of increased emission of greenhouse gases into the atmosphere. This atmospheric carbon dioxide (co2) comes from anthropogenic (caused by humans) sources. The concentration of greenhouse gas carbon dioxide, nitrous gases, and methane in the atmosphere has increased evidently due to human activities since 1800. NASA’s article adds:
The earth is warming. No credible scientist will deny this fact. Certain gases in the atmosphere, such as carbon dioxide, trap and absorb the sun’s energy and re-radiate that thermal radiation in all directions, which causes the Earth’s surface to warm. This is known as the greenhouse effect, which is another undeniable fact. The greenhouse effect is not a new concept, however the media portrays its influence to be entirely harmful on the climate. Most people fail to realize that if greenhouse gases were absent in the atmosphere, the average global temperature would drop to -18°C (Farley 69-75). It is safe to assume that the greenhouse effect is vital to human lifestyle and existence because without greenhouse gases the oceans would be completely sheeted by ice and the entire biosphere would be dramatically different. On the other hand, an overabundance of greenhouse gases in the atmosphere could also prove to dramatically change Earth’s environment by flooding most of the land on earth and then leading to a possibly massive drought. Humanity as a whole needs to realize that the emissions released during human activity, especially carbon dioxide, are greatly affecting the climate. While looking at concrete facts, even though a 1500-year natural earth cycle is evident, the fastest temperature increase in recorded earth history cannot be disregarded, and neither can the melting ice caps due to increasing atmospheric carbon
