There is a dire divide between scientists politicians in America that has potential to seriously harm the entirety of the world. Nothing represents that divide as closely as the debate over climate change. An almost unanimous amount, 97%, of climate scientists believe there is strong evidence to support global warming (nasa.gov.) In congress, over quarter of Representatives and Senators obstinately believe the opposite, no matter what evidence is presented to the contrary (thinkprogress.org.) The depth of the issue became especially apparent when Senator Jim Inhofe, chair of the Environment and Public Works Committee, brought a snowball into congress as testimony against global warming. Even after thousands of people have pointed out the …show more content…
Comparatively, something relatively cool like the Earth or a human body emits a very large wavelength. When small wavelength light of the sun enters the atmosphere, most of it doesn’t interact with greenhouse gases (such as carbon dioxide and methane) and simply passes through. Once the light hits Earth, it can either be absorbed or reflected.In the case where it is reflected, its wavelength doesn’t change and it has a relatively high chance of passing back through the atmosphere. If the light is absorbed, it will eventually be reemitted by the Earth at a comparatively longer wavelength light, which interacts with the atmosphere much more frequently. This results in more of the light becoming “trapped” in Earth’s atmosphere. If there are more greenhouse gases, it essentially increases the degree cycle’s effect. More of the light being trapped leads to the Earth having more energy, or equivalently a larger temperature. Global warming, as the name might suggest, has resulted in a rise of global temperature averages. Already, inaction over in the increase of greenhouse gases has caused the global temperature average to rise by about .7℃ (1.3℉) in the past century as shown in Figure 1.The National Aeronautics and Space Administration (NASA), predicts that it could easily rise by a further 2℃ to 6℃ in the coming century if nothing is done
The climate change is overall change, which has taken place in global climate pattern due to increase of carbon dioxide in many folds. Whether it is responsibility of individual or the government to control the climate change has become a moot point for many years. Proponents and opponents of both the views have their own strong arguments. Before coming to an end, I would like to light on both the views in my imminent paragraphs.
The globe is being rocked by extreme weather and the hottest temperatures on record. As the average global temperature soars, there are floods, droughts, unusually cold winters, forest fires, and huge storms. Are all of these horrors being caused by human-induced global warming?
As a result, it is no surprise scientists have estimated that in the last two hundred years the global temperature has risen by 1.4 degrees Fahrenheit. Maybe that does not sound like much, but consider this: it only took four degrees to bring us out of the last Ice Age. Experts agree that global warming is one of the greatest—if not the greatest—challenge facing all of humanity.
Although the climate scientists who say that the climate is changing (about 97 percent by some estimates) far outnumber those who don’t, Gore's comments indicate the strength of the
An urgent issue, climate change is undoubtedly a sweeping global dilemma of paramount importance. Though most people are aware of this fact, many either choose to ignore it, or acknowledge it, but take no action against it. Those who do choose to take action usually attempt to combat climate change by using the methods that are most commonly discussed: becoming more energy efficient, recycling, and reducing emissions through using more sustainable transportation. Though these actions are helpful, they are not the most efficient way to counter climate change.
Greenhouse gases are the main causes of climate change. The sun emits sunlight which travels to earth causing it to warm up the surface, and then the heat is radiated back towards space. This normal cycle is interrupted by greenhouse gases that stop the heat from bouncing back into space(“Global Climate Change: Causes”). The gases absorb the heat and emit it back everywhere on earth. Because the gases are causing the temperature to rise, it is known as the greenhouse effect. Gases that contribute to the greenhouse effect are nitrous oxide(N2O), methane (CH4), and carbon dioxide(CO2)(“Overview of Greenhouse Gases”).
The issue of scarcity in the face of climate change is something that cannot be completely solved without the contribution and sacrifice from every single living being on this planet. The rate at which climate change is occurring, is significantly increasing due too various factors, like "biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have also been identified as significant causes of recent climate change, often referred to as global warming." While there is a significant amount of damage that has already impacted our planet, there are still various ways that we the living beings that inhabit the planet can take action in the hopes of halting the rate at
Disagreements amongst experts in the same discipline are not uncommon; it happens rather frequently and many of these disagreements have allowed for further growth and expansion in a multitude of fields of study. Even though there is only said to be one ‘truth’, many different perspectives of that truth may coexist with one another. One’s perspective is shaped by various factors, such as religion, cultural identity, history, one’s surroundings and personal experiences that have the potential to evolve over time. The intensity of contradictions emerging out of advancing claims and conflicting claims rely on the atmosphere put in place by different points of view. Contingent upon the quality and nature of claims and conflicting claims these
Climate change has been a topic of debate for decades. Scientists support climate change is happening with hard scientific evidence whereas the people who oppose climate change have evidence which is mainly opinion-based. This report will cover what climate change is, why climate change is happening, the science that supports climate change, the different views and opinions on climate change, the effects of climate change around the world and particularly the effects in New Zealand, my opinion on climate change and my conclusion on the issue.
There is an issue on this planet that will define this generation. The issue is climate change. Global warming. A world on the collapse as our oceans are acidified, our air polluted, our forests disappearing, and human rights issues getting worse. It seems that people are not aware of how big climate change actually is. It’s not something that only takes place on the ice caps or in the forests on the far corners of the world. This is an issue that happens here, and now. It’s real. It’s happening.
Take a deep breath and imagine it is Sunday morning. The birds are chirping, the air is crisp with freshness, and the sun is radiating at a perfect temperature of 62 degrees. The coast is a 6-minute drive away, and this is the perfect day to take a short journey to the rocky shore and splash in the water. However, there is one problem, an action such as driving to the beach front will almost certainly contribute to the destructive effects of climate change. Due to this claim, is it then morally obligatory to not go on this Sunday morning drive in an effort to prevent greenhouse gas emissions?
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:
One of the main reasons that earth’s temperatures are rising are due to greenhouse gases. Greenhouse gases are created when humans burn fossil fuels such as coals, natural gases, and oils to produce heat or electricity. These gases are then capable of trapping infrared radiation sent by the sun. Once these
The concept of global warming has become one of the most widely debated and controversial topics of our time. Scientists learned long ago that the earth’s climate has powerfully shaped the history of humanity. However, it is only in the past few decades that research has revealed that humans have a significant influence on the climate as well. A growing body of scientific evidence indicates that since 1950, the world’s climate has been warming, primarily as a result of emissions from the burning of fossil fuels and the destruction of tropical forests. More importantly, an article titled "Global Warming" published in the New York Times shows that methane, a gas that is emitted from landfills, livestock and oil gas facilities,
As the idea of global warming becomes a more avidly discussed topic, we wanted to determine the truth on whether it is actually occurring. Therefore, we decided to complete a study where researchers analyzed the average minimum, average maximum, and average mean temperatures from the years 1948 to 2017, a period of 69 years. In each of the graphs constructed, there is a positive correlation between average temperature and years, meaning that as the years increased so did the temperatures.
