For the last 10,000 years, the Earth’s temperature has been fairly steady, fluctuating by only about one degree Celsius. Since human existence the Earth’s temperature has fallen within this narrow range; however, for the first time in our history we have pushed above our historical temperature range due to emittance of anthropogenic carbon emissions. Scientists are uncertain of how much warming humanity can tolerate before experiencing the most destructive and dangerous effects of climate change, but most believe that two degrees Celsius is a good starting point to aim for. Thus, the stated goal of many international climate dialogs, such as the Paris Agreements, has been to stop the planet from warming an additional two degrees Celsius in order to mobilize the action need to get the whole world to work collaboratively to solve more extensive warming. In order to prevent further warming countries must stick to and follow through on their agreed emission cuts and find innovative solutions to make more significant cuts in the future. While there is some uncertainty about how much of a problem two degrees of additional warming will be and how humanity will be able to adapt to it, most scientists such as Michael Oppenheimer from Princeton University, believe that we will be likely to see longer droughts and more intense heat waves, which will cause further disruptions to the world’s already limited food supply. Moreover, at two degrees’ sea levels could rise several feet,
A big question is climate change a hazard to future generations? Climate change is and always will be a hazard to future generations and not just for human beings, but for all kinds of species. The comprehension to accept it, is a hazard that species that cannot adapt to the change in climate are more likely become extinct. Luckily, human beings are masters of adaptability. Because our own evolution is a reason for climate change and our capability to adapt. After all, the hazards are always there should we ever fail to adapt fast enough. Our climate is always changing, both naturally and due to human effect on the environment. There were already beyond doubt, proof that animals, birds, and plants are being affected by climate change.
The world has many years existing in this galaxy and every day we see that is changing more and more but not in a very good way that it can end in the extinction of the planet earth. “Earth Hasn’t Heated Up This Fast Since the Dinosaurs’ End” (Lavelle). Carbon is growing so fast in the atmosphere faster than in the past 66 million years since the dinosaurs went extinct (Lavelle). All the presidents hold a position of power that could change this big problem that the planet is having, behind this problem there is other problems that are causing a much bigger problem in all the country. “By year 2100, the average temperature will rise by 5.8 degrees as a result of global warming. The Arctic ice is melting rapidly. By 2040 the region is expected to have a completely ice-free summer, or even earlier. Since 1880, the average temperature has risen by 1.4-Fahrenheit degrees” (Rinkesh). Humans are the one in power of this planet, they are often making some decisions, but they do not know if that is going to hurt the planet. Also, is because humans are selfish. These decisions often include manipulating the system of other country, how they work, what products they can make, how to get benefit from that country, and etc. Also, taking control and/ or credit over other countries work. Some countries are taking very serious the Global Warming problem, so the other countries want a prove of how are they helping to fix this problem. Many countries have agreements with other countries that
“Scientists have been warning about global warming for decades. It's too late to stop it now, but we can lessen its severity and impacts” - David Suzuki. Global warming, a primary topic of debate in various conversations throughout all levels of government, has been an issue for countless years. In fact, of the 134 years recorded, the 10 warmest years have all occurred “since 2000, with the exception of 1998 “(NASA). Solving a global issue such as this is not as easy as it may seem; however ,The Paris Agreement vows to do just that by setting a plan to limit global warming to well below 2°C in “the first-ever universal, legally binding global climate deal” (Europa). Before signing off on such an agreement one must analyze the many negatives
Climate is inherently variable. Climate changes from place to place and it varies with time. The world now faces one of the complex and important issue it has ever had to deal with: climate change. Climate change today is one of the biggest concerns of human beings on the planet and the effects of climate change are undeniable and it may cause environmental, social, and economic threats to the planet. We already know and easily can highlight several signs of climate change. They are: rising global sea level, widespread melting of snow and ice, rapidly changing ocean and global temperatures, and other signs. So, what are the causes of climate change? Is it natural or do human beings cause it? Well, in both cases we would be right. The climate change can be affected by natural factors, such as solar output, volcanic eruptions, and the Earth’s orbit around the Sun. Also, climate change can be affected by human activities such as, deforestation, burning fossil fuels, causing ozone hole, and building mass destructive weapons and using them on earth that causes a huge radioactivity on earth. Currently, the threat of global climate change does not threaten some nations to the extent of others. Compare the United States with the rest of African countries. We live in prosperity and in much easier time than the rest African countries. Most African countries cannot grow anything on their lands because of climate change. At the end, climate change might affect everyone on
Global warming is an increase in the temperature of the earth's weather. Global warming is also known as the green house effect. Global warming is a very serious world issue. Most humans are trying to do as much as they can to help stop global warming. Global warming has caused many problems to the earth in addition to the humans that live here on the earth. A problem caused by global warming is very hot summers. Some summers have had days that the temperature had reached 30*C. Another Problem that global warming has caused is the melting of polar ice caps. Global warming caused the polar ice caps to melt which will cause the ice to break free as well as melt in the sea, sea levels all over the world will rise. Lastly,
Scientists across the globe are being funded to research the effects of climate change. Why, some may ask. Not only does climate change affect the world around you, it affects you directly. Whether it be through air, land, or sea, the human population is not overlooked by nature. Every single person on this planet is faced with climate change symptoms on a regular basis. The focus of this paper however will be solely on how the climate change is changing weather patterns and natural climates to create more frequent, large tropical storms and increased costal flooding. These storms and flooding are often a concern for hundreds of millions of people worldwide (typically costal dwellers), with a multitude of health risks involved with them. A storm or two here and there may not feel like a problem, but when we look and find global patterns there is no denying this is not natural.
The Earth is the only home of life that humans know of in the universe thus far. Humans have lived on the Earth for an extended period of time now, and yet the human race does not fully understand what occurs on the Earth. A phenomenon which went unnoticed and misunderstood until the past couple of decades was climate change; a phenomenon of vast importance to the human race and all life on Earth. Climate change was previously seen as unimportant (and by some, still is), but as information on the affect which climate change can have on modern society came into fruition, the urgency of discovering information on what causes it also came into fruition. Many scientists believe that the acceleration of climate change may have cataclysmic consequences on humanity including: the melting of the polar ice-caps (and the rise of sea levels and loss of animal habitats due to this), a higher frequency of category 4 and 5 hurricanes forming, and an increase in both droughts and heat waves. In retaliation scientists begun extensive research on climate change; discovering that the main culprit of climate change is the process of the greenhouse effect. From this information it was seen that the discovery of climate change would have the inadvertent effect of scientists attempting to unearth possible actions which can combat the acceleration of climate change. Due to this, it is conspicuously witnessed that the main source of
Climate change is defined by the Intergovernmental panel on climate change ( IPCC) as a variation in the mean state of climate persisting for an extended period of time typically decades or longer while the United Nations Framework Convention on Climate Change (UNFCC) defines climate change as a change in the climate which is attributed directly or indirectly to human activities that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.
There is widespread agreement in the scientific community that the climate is changing and it has likely received contributions from humans in the form of increased carbon emissions. The Fourth Assessment Report of the Intergovernmental Panel on Climate Change has stated that there is ninety percent certainty that human activity has been the primary cause of temperature rises seen since 1950; if the climate rises by more than two degrees Celsius, scientists predict dire consequences to be faced by humans and the world (McMichael and Lindgren, 2011, p. 402). Changes in climate, no matter how small, bring with it changes in other seemingly unrelated aspects of life. As current research suggests, climate change will have negative effects on
Recently, global temperature is without a doubt increasing, and there is a very powerful chance that the reason for the heat range change is man made pollution. The alleged cause of this climatic change is the development of carbon dioxide, which blocks solar heat and keeps it from radiating out of the weather.
The climate on the Earth is changing. Currently, the temperature of the earth’s climate system continues to rapidly increase which leads to global warming. Global warming, by definition is the “gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants”(Webster’s). There are many reasons why global warming occurs, such as human activities and the increasing of gases; for instance carbon dioxide in the atmosphere. To reduce the issue, about 200 countries have signed Kyoto Protocol that states that they must lower four greenhouse gases. The Kyoto Protocol is an international agreement linked to the United Nations Convention on climate change and it commits the Parties to reduce greenhouse gas emissions.
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.
The greenhouse effect, in environmental science, is a popular term for the effect that certain variable constituents of the Earth's lower atmosphere have on surface temperatures. It has been known since 1896 that Earth has been warmed by a blanket of gasses (This is called the "greenhouse effect."). The gases--water vapor (H2O), carbon dioxide (CO2), and methane (CH4)--keep ground temperatures at a global average of about 15 degrees C (60 degrees F). Without them the average would be below the freezing point of water. The gases have this effect because as incoming solar radiation strikes the surface, the surface gives off infrared radiation, or heat, that the gases trap and keep near ground
Global warming is directly causing the rise in temperature of the Earth. The melting of the polar ice caps causes some of the most pressing issues including the endangerment of species indigenous to this region and the rise of ocean levels.
As Robert Frost once said, “ Some say the world will end in fire, some say in ice. From what I’ve tasted of desire I hold with those who favor fire.” This excerpt can relate to the idea of global warming. Global warming can be defined as an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. During the past 10,000 years the earth has been in an ever-growing cycle that has significantly changed the climate. These changes are becoming more prevalent in our world today in the past 150 years. Scientists have been analyzing the causes and effects of the greenhouse effect and many other issues that global warming has presented. As John Houghton
