Human And Natural Climate Change - 1485 Words

Have you ever wondered what could possibly be causing the change in our temperature? This essay delves into the meaning of climate change along with the human and natural processes that alter the globes atmospheric temperatures over a long period of time. It includes various mechanisms and feedbacks, the history of climatic change, human roles/impacts, as well as my own position on the subject. Natural Climate Change The focus of this section is to explore natural climate change- which occurs without any human influence. These natural processes have been around for thousands of years and still operate and influence the planet today despite the presence of human beings. These changes have occurred over multiple timescales and will continue to alter our climatic temperatures in the future. There is no single cause of the switch in climatic changes as many factors affect the atmospheric temperatures. Changes can occur slowly or operate very quickly over a shorter time span and either resulted due to external or internal factors. External factors include any change in solar radiation, asteroid impacts, slow movement of continents or tectonic processes. Internal factors are those within the earth itself, such as ice-albedo feedback or increases in volcanic activity. Along with these various mechanisms, there are also positive or negative feedback. Positive feedback means that it amplifies the initial change. It does not necessarily mean it is warming nor does it mean it isShow MoreRelatedHuman And Natural Drivers Of Climate Change1732 Words   |  7 PagesClimate Change in relation to Architecture Tallis Holloway - s5015034 There are many human and natural drivers of climate change, cities and buildings in particular are increasingly affected by risks linked to rapid environmental changes and their impact themselves on the atmosphere however architect s can help limit many contributing factors.

The amount of carbon dioxide in the atmosphere, as well as the cyclical processes of the Earth and Sun, affect the warming of our oceans and atmosphere. Although processes other than anthropogenic practices modify the climate, our influence on the climate since the Industrial Revolution has been unmatched.

Is it human cause or is a natural process that is happening? I think that us as humans contribute more to climate change then natural causes. Human Causes Humans affect climate change in different ways, three main ways that humans caused climate change is deforestation, greenhouse gases and Agriculture. Deforestation causes change to the landscapeRead MoreWhat Role Has Human Activity Played in Causing Climate Change?678 Words   |  3 PagesThe change in global climate is the most powerful problem that currently occurs on the earth. The problems of climate change may be caused by both of human activities and natural events. Climate change is the changes that affect the world’s weather, including shifts in temperature, ocean level, land, and precipitation. The climate change phenomenon can affect everything in the world not only natural environment, but also human society, and the world economy. This essay aims to evaluate the role ofRead MoreThe Effects Of Global Warming On Our Planet s Ecosystem1173 Words   |  5 PagesMother Earth is burning as we speak; humanity has killed our precious Earth. Global-warming is a vicious ki ller that was created by the humans on this Earth, and there s no way to cure it. We, as humans, have the power to cleanse the Earth, but instead we destroy it. Heat is absorbed by carbon dioxide and greenhouse gases. A greenhouse gas absorbs thermal radiation emitted by the Earth s surface. As the sun s energy reaches the Earth’s surface, some of it is released into space, some is absorbedRead MoreThe Effects Of Fossil Fuels On The Environment1734 Words   |  7 Pagesalternative routes or ability to make change. In consort with President Obama, many scientists believe the point of no return could occur if significant efforts aren’t made soon. Anthropogenic (human influenced) activities in comparison to natural influences have more of an impact on the environment. Since the industrial era carbon concentrations in the atmosphere have increased by thirty percent. The burning of fossil fuels and deforestation are the two largest human caused contributors to high carbonR ead MoreClimate Change : The Greenhouse Effect1199 Words   |  5 Pagesexistence, climate change has occurred. Temperatures, sea levels, quantities of gases in the atmosphere, and levels of precipitation have risen and fallen over a span of billions of years. However, over the last two centuries, climate change has been far too drastic to be caused by natural forces alone. Globally, the alterations in temperatures, sea levels, precipitation, melting of ice caps and glaciers, and violence of natural disasters are clearly caused by another factor, in addition to natural climateRead MoreHuman Activity And Climate Change1252 Words   |  6 Pagesdefine climate change as â€Å"change in the state of the climate that can be identified (e.g. using statistical tests) by changes in the mean and/or the variability of its properties, and that persists for an extended period, typically decades or longer.
