The global warming debate is a very hot topic. Some believe that it is real, while others do not. Even on the side of the people who think it is a real thing there is debate. Some people think that it is a naturally occurring event while others think that it is manmade. Those who believe it is manmade think that too much carbon output is the cause. This is the stand that former vice president/presidential candidate Al Gore takes in his academy award winning documentary, An Inconvenient Truth.…
The Earth’s climate has changed over the last century. Increases in average temperatures have been seen around the globe and there is new and stronger evidence that most of the warming observed of the last 50 years is due to human activities.…
Global climate change has been a subject of much discussion for some time now. The earth has naturally gone through heating and cooling phases in its lifetime. Most scientists agree that these changes aren’t solely the product of humans, but that the time required for natural climate change has been decreased due to humans. This has led to new problems for the earth and all of its inhabitants. According to research the earth is warming at an average of 1.2-1.4° F every 100 years (epa.gov).…
2) Scientist view climate change with more urgency now than they did in 2007 because before scientist and even the most sophisticated computers thought that the sea ice “would not disappear before the middle of this century if then”. Meaning that in the middle of the 21st century the sea ice in the Arctic would disappear but even then they weren’t sure but now scientists think that the summer ice in the Arctic could disappear as soon as 2020. Another factor scientist view climate change with urgency is because the U.S has not responded to the change of limiting green-house gasses. This is a big deal because the U.S is the second most carbon emitting county that dishes out 5,610,000,000 metric tons of carbon.…
For the last 2.5 million years, global temperature has shifted between cold glacial periods that last for around 100 000 years, and warmer interglacial periods that last for around 10 000 years. Right now we are in an interglacial period. 20 000 years ago the Earth was cold. Around 15000 years ago it started to warm up, this was the end of the last glacial period. Over the last 10 000 years the climate has been warm with minor fluctuations, however over the last 1000 years the climate has been fairly constant with small fluctuations in annual temperature. Over the last century global temperature has increased rapidly. This is called global warming; there has been a sharp rise in average temperature, 0.7oc between 1900 and 2000. The temperature increase over the last century has been very fast. There is a consensus among scientists that the changes in climate over the last century are a result in human activities (anthropogenic causes), including Al Gore, as shown in the statement which I agree with. I think the majority of global warming is due to humans therefore it is our right to try and find solutions to diminish global warming as much as we can.…
The climate change debate, as it discussed in the mainstream media, appears to be divided into two major sides. One side argues that the current global warming is caused by human factors while the other side insists it is occurring because of natural forces. In the latter argument, two natural causes that dominate the conversation are solar changes and changes to the Earth's orbit.…
The view that human activities are likely responsible for most of the observed increase in global mean temperature ("global warming") since the mid-20th century is an accurate reflection of current scientific thinking. Human-induced warming of the climate is expected to continue throughout the 21st century and beyond.…
Controversy over global warming exists as a dispute regarding the nature and consequences of global warming. The theory of global warning as presented in the mainstream media currently assumes that carbon dioxide is an atmospheric greenhouse gas and since humans are producing more carbon dioxide than previously, the temperature must therefore rise. The cause of global warming is not actually known, but in it 's simplest terms the debate boils down to whether or not global warming is caused by human interference or part of a naturally occurring cycle. The debate has recently become one-sided in favor of human interference due mostly to three factors: political pressure on scientists to produce research that supports the global warming theory, public misconception of what scientific consensus is, and an irresponsible that media promotes sensationalized viewpoints to sell advertising.…
Thus, any impartial jury should not come back with a “guilty” verdict convicting humanity of forcing recent climatological changes. Even the most ardent supporters of global warming will not argue this point. Instead, they argue that humans are only partially responsible for the observed climate change. If one takes a hard look at the science involved, their assertions appear to be groundless.…
The debate between whether global climate warming is due to manmade causes or natural ones is an ongoing socio economic and political debate.…
Robert Cooke’s article “An Arctic Floe of Climate Question” presents a more reasonable argument. In Robert Cooke’s article he wants to prove that global warming has really begun and it is affecting us humans. The author provides strong evidence in the following statement, “A recent University of Wisconsin study has shown that in the Northern Hemisphere many of the rivers and lakes that freeze are doing so later—by 8.7 days—than they did more than a century ago.”(Cooke 11) In other words, it’s stating a cause of global warming which is that rivers and lakes are taking a longer period to unfreeze than they did before. Another example of strong evidence is this, “Temperature records also show, clearly that globally temperatures have gone up by about 3 degrees Fahrenheit in the past 150 years, or since temperatures have been recorded.” (Cooke 11) On the other hand, it’s telling us general cause of global warming which are temperatures has gone up in the past years. Even though, these are very convincing facts one weakness this article has is, “So we can’t say it is something that was unprecedented.” In addition it’s saying they…
According to the article Global Warming on NASA’s website, published by Holly Riebeek on June 3, 2010, between 1906 and 2005 the Earth’s average surface temperature rose between 1.1 to 1.6 degrees Fahrenheit. This is not the first time the Earth’s climate has changed. The climate has experienced changes since the beginning of time. Small differences that occur in the Earth’s orbit cause a somewhat different temperature. The sun is the main ingredient when it comes to temperature. In the past, the Earth’s orbit has changed, causing a slight change in temperature (Riebeek 1). This is not what the controversy sweeping the world. The problem is the more drastic change recently because of humans. The Earth has a natural heating mechanism called the Greenhouse Effect. The Greenhouse Effect is a necessary part of human existence. However, the problem is humans are increasing these greenhouse gasses by burning fossil fuels, such as oil, and burning down forests, increasing the carbon dioxide level (2). Without all this, humans would face an inevitable downfall.…
Government officials under the Republican Party and their supporters are the most common doubters of climate change today. They will often either argue that climate change does not exist, or argue that the changing climate is natural, and would have happened with or without the existence of humans. There is scientific evidence to disprove this, but these skeptics turn a blind eye. According to NASA, 95% of climate scientists agree that humans are the main cause of global warming, due to our expansion of the “greenhouse effect”, a process in which the earth becomes like a greenhouse: gases in the atmosphere trap heat and radiation close to Earth, slowly warming the environment. The average surface temperature has risen about 2° Fahrenheit since the late…
The earth has been around for billions of years and many issues in our time as a species have risen up. One matter that has come up is the issue of global warming or climate change. This conflict has been around for many years, but has started to get worse every year, since the United States and other countries have been emitting carbon dioxide into the earth’s atmosphere. Global warming is an urgent issue; moreover, there exists a controversy on whether humanity or nature is the cause, and the scientists who consider this a serious matter are entirely correct because humans are at fault.…
In the past 100 years, the temperature of our Earth has increased by about 4.5 degrees (Guggenheim). This may not seem like a lot, but on a global scale, it can have a huge impact. Global Warming is a serious problem, and it should be taken very seriously. Unless we take action now, we will have major consequences to deal with later on. These include, but are certainly not limited to, extreme weather, a decline in polar life, and effects on human health. It seems like Global Warming has become such a political issue that people tend to take a side based solely on the political party they support. This needs to stop. No matter where you fall on the political spectrum, you cannot ignore the facts. The temperature of our atmosphere has been increasing at an alarming rate in recent years. Global warming is happening, and action needs to be taken to stop it, no exceptions.…
