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.
Climate change has been happening since late nineteenth century, but has increased significant since then. The world’s oceans are steadily warming up and ice is melting. Furthermore, the factories and cars are causes of global warming. There are a lot of cars and factories in the world but its danger for atmosphere. Also, one more causes
Climate change can be defined as the study of weather patterns over an extended period in any environment and at any time of year. Global warming relates to climate change because it is the ongoing increase of Earth’s normal temperature. The cause for climate change is due to the rise in concentrations of greenhouse gases in the atmosphere like carbon dioxide, methane, ozone, and water vapor. Issues that arise because of climate change are sea levels rising, growth in ocean heat content, and buildup of carbon dioxide in the atmosphere due to human activities. Humans contribute the most to climate change by engaging in driving, burning fossil fuels, and natural gas distribution. Climate change is conceivably evolving due to human activities and minimally biological factors but, climate change is still a scientific phenomenon that requires further investigation.
Basically, this article is about the climate change, which is having a general tendency of going up. It can be divided into three parts. In the first part, it presents a prediction that any summer between 2061 and 2080 will be warmer than the hottest record, and it’s going to affect around 80 percent of the world’s land area, including Antarctica. And the second part is a description of how the group of scientists gets this prediction. By constructing simulation models, those scientists establish a large range of temperature that will possibly occur in the future. The third part propose that reducing greenhouse emission would decrease the possibility of the future summer breaking the record, especially in some areas.
The North pole is one of the main places affected by global warming . The Arctic and the Antarctica are both vulnerable to the climate that has changed overtime. The ice caps have promptly melted overtime that they are now differently than they were. (The Arctic ice cap is less than ten feet thick on average). The ice are spread apart floating in the ocean making it hard for animals such as the polar bear to travel one place to another. This creatures must now swim through long distances of waters some becoming exhausted and drowning before reaching to the next
Global Warming is an ongoing problem in the world which causes the average global temperature to increase near the earth surface. This has affected many animals, especially the polar
The most well-known climate change must is the global warming due to the inclination of greenhouse gas in atmosphere, which is a common issue for all human beings and ling creatures. For examples, the melting of arctic glaciers, one of the most critical consequences of global warming, has caused severe damage to the species diversity of the living creatures of entire Arctic Circle. Polar bears and seals are two of most influenced living creatures in Arctic Circle since their habitats have been highly eliminated and invasive creatures have severely negative influences on their life. Now, although many countries have acted to rescue polar bears and seals, but scientists predicted that their situation would continuously worsen in the future.
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 melting ice caps are having a dramatic affect on the polar regions of the earth. For example, the average temperature in the Arctic is rising twice as fast than the rest of the world (nrdc.org). The once prominent ice is now melting at a dramatic speed, which is affecting native people, wildlife, and plants. When the Ward Hunt Ice Shelf splintered, the freshwater lake that it surrounded drained into the ocean, along with the ecosystem that inhabited it. Polar bears, whales, walrus and seals are changing their feeding and migration patterns, making it harder for native people to hunt them (nrdc.org). Because of the flooding, entire villages will be uprooted order to avoid being swamped. Also, the Arctic coastlines are beginning to move as well. The melting ice caps are threatening the native peoples’ cultural identity and their very survival. Ice-dependant animals, such as walruses and ring seals will be greatly affected by the melting ice caps (treehugger.com). They have fewer places to rest on, as well as fewer places to hunt. If the ice caps keep melting, their lives will become in great danger. The melting ice caps are not only affecting the Polar Regions, but they are also affecting the rest of the world as well in the form of rising ocean levels.
There is noticeable change in the climate of the earth through the passes of the time due to natural factor as well as the human activities by the production of the excessive amount of the gases responsible for trapping the energy. The change in the earth climate is influence by human civilization by the production of the different greenhouse gases like carbon dioxide, water vapor, and sulfur dioxide gases. Its true that the temperature of the earth is increasing. The phenomenon of the global warming can be seen as the temperature of the earth surface is increasing throughout the world. There are many evidences that shows that the earth climate system is warming. Different studies done at different period of time shows that the temperature
People have increased 40% the amount of CO2 (“Basics of Global Warming” 2). To this day there is more CO2 in the atmosphere than there has been in the past 8000 years (“Basics of Global Warming” ). The ozone layer is beginning to get smaller and smaller and is letting more heat into the Earth. Precipitation has increased. Sea level has risen faster than in the last century (Effects of Global Warming” 3)
The effects of climate change are much more complex then a simple rise in temperature. Habitats and the species that rely on them are disappearing, in what I view as a ‘snowball effect’ of biodiversity loss. A reduction in a species habitat will have dire consequences for them as well as other species that co-exist with them, over time every aspect of that environment is affected. In the Artic, sea ice is melting at a faster then it has in centuries. According to an article published by Aarhus University "Climate change is by far the worst threat to Arctic biodiversity. Temperatures are expected to increase more in the Arctic compared to the global average, resulting in severe disruptions to Arctic biodiversity some of which are already visible” (Aarhus University, 2013). Among the many species being affected, the polar bear population has already experienced serious decline because of its reliance on sea ice. Polar bears rely on the sea ice to hunt, breed, and, in some cases, den. Changes in their population and distribution are starting to become noticeable within the Arctic ecosystem. There are social, environmental and economic effects associated with the negative effects climate change has on the polar bear population. Because of these dire consequences related to climate change, swift action must be taken in order to help protect this species and its environment.
Climate change is one of the world’s biggest threats. Climate change has been and currently still is affecting the planet. It affects the environment, animals, plants, the ecosystem and it affects humans as well. However, even though climate change affects humans, we also play a big part in contributing to climate change. For example, the amount of CO2 in the atmosphere has gone up due to the burning of fossil fuels (from human activity) as well as deforestation (clearing or removal of trees) which requires human participation (Reece). The rise of CO2 affects the global temperature and human activities only add to the climate change. As stated before, climate change not only effects humans, it also effects plants and animals. For instance, with climate change happening, plants and animals are experiencing drastic changes in their habitat. Therefore, plants and animals have to migrate to an environment better suited for them. (Reece). Climate change has also had an effect on the arctic as well as plants, animals, humans, etc. It is said that climate change is known to be the greatest threat to the arctic as we know it. For example, the arctic sea has already experienced the largest amount of warming in 2012 and it is suggested that within a few decades or so there may not be any more ice. Henceforth, the habitat for seals, polar bears and other mammals will be decreasing and their species will be at risk (Reece 2011). There have definitely been some significant changes that
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.
Global warming is a very important issue of which there are divided opinions. During the last 50 years global warming has increased at a remarkably accelerated speed, which may raise suspicions to find out why this is happening in this way. Some people believe that global warming is not real, but scientists say that if we do not slow gas emissions to the atmosphere, temperatures could rise by about 10 ° in the next century. There are many theories and reports that try to explain the reasons why this remarkable increase in temperature is happening. There is only one thing that is certain, and that is that if we do not join together to do something before it is too late, our planet will suffer great damage.
