Recommended: What are the causes of global warming
Global warming is the rise of temperature of the Earth. The main cause of global warming is the greenhouse effect. The way humans behave is the reason that greenhouse gas trap more heat. Automobiles are the main cause of the greenhouse gases to to trap the heat. Global warming doesn’t completely mean a constant rise in temperature, it is mainly a change in temperature.in patterns.
The two major greenhouse gases include methane and carbon dioxide. Carbon dioxide and methane normally come from Earth’s atmosphere. The greenhouse gases are enhanced because of our human activity. The greenhouse gases are known as synthetic chemicals.
Our Earth has had at least five ice ages. The very first ice age we have had occurred nearly 2 billion years ago. Also, our most recent ice age started happening close to 3 million years ago. The most recent ice age is still happening today so technically we live in an ice age. An ice age is a long period of time when the planet is semi-cold and the earth is covered in giant sheets of ice in some areas. During an ice age we experience short flashes of very warm weather. Sometimes during the heat flashes the glaciers can melt.
The medieval warming period happened from about 950 through 1250. The medieval warming period was a time when the temperatures were risen in the North Atlantic region. The medieval warming period took place in the European middle ages. Recently after the medieval warming period there was a cooler time called the little ice age.
The little ice age lasted from 1250 to the end of the nineteenth century. It has been found that neither the little ice age or the medieval warming period were global, the two only took place in the North Atlantic region.

...gases to go into a strong effect. The greenhouse gases trap all of the heat in our atmosphere and make it hotter. Humans have let ultraviolet rays into the ozone layer. Destroying the ozone will make the Earth much hotter.
The temperature is rising at very fast speeds. In the last hundred years our Earth’s temperature has risen a full degree. The temperature is rising because of what us humans are doing to the environment.
Besides the greenhouse effect, one of the most harmful thing to global warming is the ultraviolet radiation. I agree that global warming is a moral issue because it is our fault. We have to work together to prevent global warming. We need to find a better way of transportation and better ways of not enhancing the greenhouse effect.

The European middle ages lasted from the 5th century to the 15th century, which started the fall of the Western Roman Empire and moved to the Renaissance and the Age of Discovery. The classical antiquity, the medieval period, and the modern period were the divisions to the early, high, and late middle ages. The gothic awakening was in England during the 1750s, caused by the medieval forms. Medieval Europe was awakening from a feudal war and ignorance. The new way of learning was spread in the western society. In the gothic awakening age, towns and kingdoms flourished and built churches across Europe.
The years between 500 A.D. and 1400 A.D. were most commonly known as the Middle Ages. The Middle Ages was a time period where several events had occurred, each supporting a different label for this era. The Middle Ages deserve the titles of the Age of Feudalism and the Dark Ages because people needed stability and relied on higher government officials for protection, and there were many wars and there was no organized government. However, the Middle Ages can be best described as the Age of Faith because the Church had power over every citizen. Although there are more labels to describe the time period, these were the best titles to describe Europe after the fall of the Roman Empire.
First, during the last few decades the Earth is experiencing greater rate of rising temperatures due to greenhouse gases that are being produced by human activities rather than because of environmental reasons, such as solar or volcanic activities. In 2006 the President of the National Academy of Sciences stated: “There is no doubt that the Earth is warming,” also he added that people are at least partly responsible for these changes in addition to regular factors (Cicerone, par.4). Natural factors have produced climate fluctuations on Earth for several million years. People have effected an atmosphere of the Earth just for nearly one hundred years, since Industrial Revolution has begun (Revkin 340). Of course, it is unfair to say that global warming is caused entirely by humans. For example, people can not have an impact on the position of Earth in relation to the sun, or on the galactic density, or such nature events as air emissions of volcanic gases. As a result of these environmental factors, Earth usually had higher rates of temperature fluctuations during the previous million years than it has in later centuries. On the other hand, people are responsible for the highest concentration of greenhouse gases during the last 650,000 years in the atmosphere due to industrial manufacturing, driven by the increase in consumer consumption (Lindsey, par.
The Little Ice Age was a period of time in which parts of Europe and North America were exposed to colder winters than those generations before and after. This phase lasted a surprisingly long time from around the 1300’s to about 1870. Although it is not considered to be a full on “ice age”, it is said to have many effects on history including important roles on defining how we currently live today.
The Precambrian era is about 90% of the earth’s geologic life. It refers to all geologic time before 600 million years ago. During the Precambrian era, the earth formed along with the oceans and atmosphere. Originally, the earth was in a molten state, but as it cooled down, it developed a hard crust and oceans that developed water vapor to form an atmosphere. About five hundred million years after the earth was formed, small continents started to form. The plate tectonics also started to build up. As the earth grew older within this period, the layers of the earth started to form. The continents were thought to be joined together in one super continent. It is thought that the end of the Precambrian era was the start of a global ice age.
The Little Ice Age is the name for the period of cooling spanning from 1400 to 1900 c.e. that took place after the Medieval Warm Period. Scientists believe that solar minimums and reversals in the Northern Atlantic Oscillation, a large atmospheric-circulation system that affects weather in the North Atlantic area including Europe, drove these changes (Encyclopedia Britannica, 2014). It is often assumed that the Little Ice Age had a global impact. However, in 2001, the Intergovernmental Panel on Climate Change put forth in a climate assessment report that though there were glacial increases in other parts of the world, they were not synchronous with the glacia...
The rising of temperatures is caused by factors called climate forcing or “forcing mechanisms”. This includes processes such as variations in solar radiation, variations in the Earth’s orbit, mountain-building and continental drift, and changes in greenhouse gas concentration. Solar radiation gets trapped by gases, which are created on earth, in the atmosphere. The radiation comes from the sun towards earth and bounces off the earth’s surface. However much of the radiation gets trapped by the gases remaining behind which warms our planet instead of going back into space like previously. This is known as the greenhouse effect. Some of the major contributing gases are; water vapor, carbon dioxide, methane, and our ozone layer. According to sources at Real Climate, 36-85% of the greenhouse effect is due to water vapor (including clouds), followed by carbon dioxide at 9-26%, and last all the minor greenhouse gas absorbers at 7-8%. Humans contribute to the greenhouse effect by deforestation, land use changes, and burning fo...
Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over
The last thirty years have been warmer at the Earth’s surface than the previous years since 1850. Case in point, it was reported that in the Northern Hemisphere the last 30 years (1983-2012) were the warmest in the past 1400 years.
The climate on the Earth is changing. Ice age is interleaved with the global warming. In the present age, the temperature of the Earth's climate system continues to rapidly increase and it leads to global warming. Global warming is the process of gradual growth of average annual temperature of the atmosphere of the Earth and World oceans. The average temperature on the Earth was increased by 0.6C. There are various reasons for global warming, such as human activities, natural events, increasing of gases, such as carbon dioxide in atmosphere and solar activity (Global warming).
Our world is always changing, so is our climate. Some changes are apparent, others not so much. Climate change is an important issue of concern in the twenty-first century. Environment, if it changes at all, evolves so slowly that the difference cannot be seen in a human lifetime (Wearth, 2014). Mostly all scientists predicted that it would take thousands of years for the planet to warm up due to emissions of carbon dioxide from fossil fuels called greenhouse gases. But in the past 200 years, things began to change. The rate and the amount of warming that is happening on this planet are unprecedented. Wearth says, “People did not grasp the prodigious fact that both population and industrialization were exploding in a pattern of exponential
It is known that in the last 650,000 years there have been seven cycles of glacial advance and retreat with the last one 7,000 years ago. This was when the modern climate era started which lead to the beginning of human civilization all
Global warming and climate change are not the same thing. All though a lot of newspapers, magazines and commercials use them so much it’s as if they were and many people believe that they are. Global warming actually is when the earth loses more energy than it’s suppose to gain. The Climate uses that energy that earth receives and the energy that is radiated away from the earth. When it is balanced correctly then the climate is more normally how it is and more stable. Climate change is a long period of a places average weather like said in the above sentences, but also it s...
Currently, scientists believe that once an ice age has been triggered, oceanic circulation currents can change and the mixing of the oceans cools the southern hemisphere. As glaciers begin to accumulate in the northern hemisphere, solar heat is reflected off the snow which leads to further cooling.
The common definition of global warming is a gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide and other pollutants (Global warming, Wikipedia). Moreover, the effects of global warming will bring ecological and social changes. Because there is no exact way to predict the effects of global warming, it is almost impossible to say how strong global warming will affect life in the future.
