Essay About Climate Change

The earth was covered with extensive polar and mountainous sheets of ice. So much water was taken up with ice that the global sea level dropped almost 140 meters. This time in earth’s history would be considered a glacial period. Oceanic circulation, solar energy fluctuations, continental positions and earth 's orbital cycle caused these conditions. Glacial global temperature changes between the ice ages and interglacial periods were due to the concentration of greenhouse gases.

Many of the ocean’s and Great Lake’s properties can be altered due to climate change. The two important indicators of climate change in the Atlantic Ocean and Great Lakes are sea level and sea surface temperature. In the Atlantic Ocean, as greenhouse gasses trap more energy from the sun, the ocean is absorbing more heat. This results in an increase in sea level and sea surface temperature. The overall increase in sea surface temperatures has occurred during the past three decades.

Convection currents, seafloor spreading and rift valleys also drive the movement of the Earth’s plates. When Gondwana drifted apart, Antarctica, South America, Africa and Australia moved into the southern hemisphere and the Arabian Peninsula and the Indian Subcontinent moved into the northern hemisphere. The tectonic plates are always moving and the Australian plate is moving northwards at about 3cm per

On the other side, there is sharp decline in sea cover; glaciers and sea ice. Because of climate change, the earth is getting warmer, rain patters are changing, and snow and ice are melting at an alarming rate. As the global temperatures continue to rise, it is evident that we are going to see more changes in our climate and environment which changes are going to have severe effects on mankind and natural ecosystems. Over the past years, the Earth’s climate has been affected by natural factors that are external to the climate system, such as changes in volcanic activity, solar output, and the Earth's orbit around the Sun. In terms of the Earth’s energy balance, these factors primarily influence the amount of incoming energy and changes in solar irradiance which has contributed to climate trends over the past century.

By far the biggest factor causing to climate change is the burning of fossil fuels for electricity and transportation. This process takes carbon that has been underground for millions of years. Later, it moves into the atmosphere, as carbon dioxide, where it will influence the climate for many centuries into the future. So, now it’s pretty obvious that it all comes down to

The earth has gone through several climate changes through its 4.6 billion year lifetime. It’s a natural process that the earth goes through during its lifetime, but something

These gases retain heat on earth thus increasing the temperature above average. Different gases have dissimilar abilities to trap heat. Deforestation is also another important reason for global warming. Plants release oxygen and take in carbon, thus providing us a clean and healthy environment. But by deforesting the lands, the trees would emit the carbon stored in them from hundreds of years making the air impure.

The impact of human activity and the emission of carbon dioxide in the earth’s atmosphere is linked to global warming. Sea surface temperatures have steadily had increases up to about 1.5 degrees Celsius over the past 54 years. Climate change continues

Climate Change is one of the most unsettling problems mankind faces today. It leaves an impact on every single living thing, on every continent, no matter the privilege. Long term investment must be used to change the world. People must do more than just change out their light bulbs for eco-friendly ones, or drive fuel efficient cars. A choice as simple as changing our diets could reduce a human’s carbon footprint by fifty percent.

Climate Change is something that we have caused because of our choices to burn fossil fuels, at some point we have to face the problems that we have created. The consequences of Climate Change are horrific and Climate Change could end our existence as a species, most people do take action against Climate Change except, The Government of the United States of America, refuses to accept the serious dangers of climate change and continues releasing propaganda on Climate Change, claiming its effects are minimal and that we are not causing it. Peculiar how almost every other government in the world thinks otherwise. The reasons we are heading in the wrong direction is because the actions of humans are causing Climate Change, and almost all scientists agree on this matter. Another reason is the that the government isn’t trustworthy in what they say about Climate Change, meaning what they say about Climate Change is wrong, and we should change our policy on Climate Change.

Climate change refers to a is the change of a region’s or city's’ typical weather. Both human and natural causes can affect the Earth’s energy balance. Factors include, dissimilarity in the sun’s energy reaching Earth and the buildup of greenhouse gases in Earth’s atmosphere. The United Nations Intergovernmental Panel on Climate used scientist from 27 different countries to report a world policy on Climate change.

THE EFFECTS OF GLOBAL WARMING AND THE WAYS TO OVERCOME Nowadays, global warming has grabbed the experts and the scientists’ attention. It is the most critical issue that our world facing in the 21st century. Global warming is the gradual heating of Earth 's surface, oceans and atmosphere. Global warming occurred, when carbon dioxide increases in the air and the air start to be warmer and hotter.

Humans are the most influential and destructive living things on this planet, and our mistakes are starting to have an effect on our lives. These actions have created the occurrence we know as global warming. This is the average warming of the Earth’s atmosphere and oceans by way of natural warming processes, but is greatly amplified by human emissions of greenhouse gases and pollution. Carbon Dioxide is the major gas that we pump into the air every day, as waste from industrial processes, transportation emissions, and energy production. These gases in the Earth's atmosphere lead to heat that is reflected off the Earth from the sun’s rays to become trapped, creating higher temperatures in the atmosphere, which is in turn, absorbed by the oceans.

There are two main causes of climate change: natural causes and human causes. Natural causes that influence climate change include volcanic eruptions, ocean current, earth orbital changes, and solar variations. Those natural causes contribute small part of climate change; however, the biggest part in climate change is caused by human. The spectacular increase of human population, contribute significantly to the climate change. There are more than 7 billion people live in the world now, compared to about 3 billion people in late 1960s.

One of the causes which has caused the biggest impact has been climate change. All the debate revolving around Global warming has become very relevant. As you may already know, global warming refers to
