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.
Based on these facts we can consider: "that Climate change is a result of natural occurrences of the adjustments done by the climate systems "or" a result of anthropogenic (man-made) factors leading to an acceleration of global temperatures witnessed in the past century". Natural adjustments to climate systems:
Scientists have discovered 'climate forcing’s ' influence variations in climate systems and based on the depth and period of such forcing’s the adjustments to climate may be in a shorter or longer earth cycle. Natural forcing’s like variations in earth 's orbit, solar variation, volcanic eruptions and motion of tectonic plates have influence on the Earth 's climate
At the outset, there are numerous reasons why the climate change is probably caused by human activities, and the most conspicuous one stems from the fact that the phenomenon became increasingly obvious as the technology advances. For example, a recent seminar conducted by the University of Sydney manifested that the pullution is
Climate change can be defined as a significant change in the “average weather” of any given region sustained in the long-term and can be caused by Earth 's dynamic processes, external forces including variations in sunlight intensity, and also by human activities (USEPA, 2014).
Everyone talks about climate change and how the Earth is slowly deteriorating, but no one seems to have specific examples. In Linnea Saukko’s “How to Poison the Earth,” she does use specific examples of what is causing climate change. She uses satire with a hint of sarcasm in her essay. She gives the reader specific examples of how to poison the Earth, but not really wanting to poison the Earth. Gretel Ehrlich writes her essay, “Chronicles of Ice,” a little differently. She uses personal experiences of visiting a glacier and the way that it is falling apart to explain climate change. She uses detailed, sensory description to explain
Climate change has been a widely debated, controversial topic. Some think that it is not an issue that should be payed much attention to. With climate changing being caused naturally and by humans, the climate has been widely changing due to ample amounts of CO2 emissions. Where the burning of fossil fuels is the main source of the human impact. As well as volcanoes being a majority the of natural emissions. Although nature contributes to the climate change humans have more widely contributed to the change of climate abroad.
Climate change is the term used to describe the warming of the average surface temperature on earth. Climate change; often referred to as the general term global warming, is a topic that often inspires fierce debate among those on both sides of the issue. One thing those who are pro and those that are con both agree on is that the temperature on earth has increased over the past century by an average of 1.4 degrees. The big debate on the two sides is if the warming temperatures are caused by human activities and if it is not stopped it will have dire consequences (the pro side) or if it is the result of natural causes and the earth’s surface will find ways to adapt such as crops becoming more heat resistant (the con side).
Climate change has been a big global issue, and there are many reasons that scientists have proposed. The factor on climate change includes solar radiation, the Earth's orbit changes, orogeny, greenhouse gas emissions. The impact of climate change relative to changes in climate factors, it may take long time to emerge.
The human race all around the world wonders if the climate is changing due to human activity or if it is just a natural occurrence. At certain parts of the Earth's surface, the climate can be observed much differently than other locations. As the years go by the average temperature of the Earth increases by little intervals. There are several different reasons why people believe the climate is changing every year. However, the increase of worldwide population and production of heat to the atmosphere is due to the increase of human activities that take place on a daily basis. Human activity is the main cause of the global climate change. The human impact on climate exceeds any known changes due to natural processes. The impact of this human activity is often misunderstood when looking at climate change.
Climate change is a rising issue of importance in our day and age, and one that is threatening our global society on many levels. In the past few decades, scientists have discovered that our planet’s climate has been changing at an alarming rate. The way in which we have changed the land to
Climate change is defined as the increase of the average surface temperature on the earth. There is speculation that this climate change is due to human activity, but there are skeptics that say that it’s the earth’s natural variation of temperature. Even though natural variation is evident, data reveals that the extent of this climate change isn’t only effected by natural variation.
Climate change is defined as the change in global or regional climate patterns, which is apparent from the mid to late 20th century onwards. When looking at climate change there is an abundance of evidence that supports that humans are the leading causes of the drastic shift in the weather pattern but there is also a lot of evidence against humans actually causing climate changes. For example, the increasing levels of man made gases that are let into the atmosphere may have created a greenhouse effect, which traps heat and ultimately causes global warming. But there are also many scientists who believe that the earth has always naturally cooled down or warmed up at its own pace.
The planet has been experiencing considerable climate change for the last several decades. There have been many explanations toward the main causes of the increased warming of the planet. On one hand are the environmentalists who believe that the major cause of this increased warming of the planet is the increase in greenhouse gases in the atmosphere induced by human activities. On the other hand, the scientists believe that there are natural causes of global climate change. While the supporters of the man-made theory of global climate change reason that the major greenhouse gas causing global warming is carbon dioxide, the advocates of natural causes
“Our generation has inherited an incredibly beautiful world from our parents and they from their parents. It is in our hands whether our children and their children inherit the same world” (Richard Branson). This quote is a brief rewording of the issue we have today with global warming. For those who are not aware of what global warming is, it is when too much carbon dioxide is added into the atmosphere. Global warming can cause sever hurricanes, intense weather, and many other natural disasters. For example, the lack of protection to our species and natural resources has led to many conflicts around the world. The lack of conservation of natural resources and need for habitat protection has had a major impact on the environment also.
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
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 is
This issue is no longer a myth, hoax, or conspiracy among scientists. Climate change is very real. Climate change is a change in the statistical properties of the climate system when considered over long periods of time, regardless of cause (NASA: Evidence). The term climate change is often used to refer to anthropogenic climate change. Anthropogenic climate change is caused by human activity, one of the biggest causes of climate change (NASA: Evidence). It was found that human activities had the potential to drastically alter the climate. The term climate change replaced climatic change as the dominant term to reflect an anthropogenic cause. Certain human activities have been identified as primary causes of ongoing climate change. The term climate change has become directly related with anthropogenic global warming. Global warming refers to surface temperature increases while climate change includes global warming and everything else connected with increasing greenhouse gas levels (NASA: Evidence). Climate change refers to a change in average weather conditions, or in the time variation of weather depending on the conditions.
