Overall global warming will impact life on earth in many ways but the extent of the change is largely dependent on human activities as scientist have shown that human emissions of greenhouse gases are pushing global temperatures up. It can therefore be concluded that climate change is the long-term averages and variations in the weather over a long period of time were as anthropogenic climate change relates to the effects human activities have on the greenhouse gases and as the greenhouse gases are long-lived, therefore the planet will continue to warm and changes will happen in the future, but the degree to which global warming changes is up to the human activities affecting climate
Climate change is believed to be the biggest issue facing the Earth. It is a long-term change in the Earth’s temperatures and climate (“Climate Change”, Dictionary.com). Our atmosphere is part of the reason why we can live on Earth with reasonable temperatures. Humans have been emitting unnatural greenhouse gases, like coal, oil, and gas. This is changing the natural systems that take place in our atmosphere.
Global warming is a rise in the surface temperature of the earth. The issues that cause Global warming are divided into two categories natural and human influences. There are some natural reasons why Global warming is occurring. The climate has continuously
Climate change and global warming is the changes in the earth’s weather, wind patterns and rainfall. These changes are the result of increase in temperature of the earth’s atmosphere which is caused by the increase of particular gases, especially carbon dioxide. Carbon dioxide is a vital gas for plant life on earth and is formed during respiration. Although there are two types of carbon sinks- man-made and natural, in this essay, I will focus on one natural carbon sink- forests, however, I will give a brief insight into another carbon sink. Firstly, I will introduce and discuss forest as my chosen carbon sink, how it works in relation to soaking up carbon dioxide and how it benefits the environment.
Climate change is refers to the rise in average surface temperatures on earth, mostly due to the burning of the fossil fuels such as oil and coal, which emits greenhouse gases into the atmosphere which are primarily carbon dioxide, water vapor, methane, nitrous oxide, and chlorofluorocarbons (#02). In addition, other human activities, such as agriculture and deforestation, also contribute to the growth of greenhouse gases that cause climate change (#01). According to this, many have make their own conclusions on how are humans responsible for climate change and whether or not it is a real thing. Some people think and guarantee that climate change is real and it is happening at least in part because of human activity. This people argue that in the last 100 years, carbon dioxide concentrations in the atmosphere have risen from 290 parts per million (ppm) to 369 ppm, with strong evidence pointing to the burning of fossil fuels by humans as a primary cause of these increases (#03).
While orbital forcing is the primary external driver of glacial cycles, carbon dioxide content in the atmosphere plays this important internal feedback role (Pittock, 2005). Evidence for environmental change in the Pleistocene epoch include constituents of gas bubbles trapped in ice cores. According to BAS Natural Environment Research Council (2015), Ice cores are cylinders of ice drilled out of an ice sheet or glacier, with most of them coming from Antarctica and Greenland. Looking at ice cores can provide direct information about past climate change, going back as far as at least 800,000 years. They also provide evidence that under some circumstances climate can change abruptly.
It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossils fuels and release of harmful gases by industries. Climate change has various harmful effects but not limited to melting of polar ice, changes in seasons, occurrence of new diseases, frequent occurrence of floods and change in overall weather scenario. • Loss of Biodiversity: Human activity is leading to the extinction of species and habitants and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollution is crucial to the survival population is decimating.
Volcano eruptions, solar output (amount of energy the sun puts out), and the earth’s rotation around the sun all are natural causes in why the climate changes. Climate change caused by human interaction is mainly due to the burning of fossil fuels like coal, natural gas, oil, and other fossil fuels for energy. We are releasing a dangerous amount of carbon dioxide (CO2) in the atmosphere, which make the greenhouse effect stronger. There are two other types of gases that are also released by human activity, which is making the greenhouse effect stronger. These gases are methane (CH4) and nitrous oxide (N2O).
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.
There are some specific waste and agricultural management practices that increase the burden on earth by releasing other global warming gases. These other gases include nitrous oxide and methane. Scientists claim that 95% of global warming is caused by the increasing concentration of the greenhouse gases and other activities made by humans. There are many causes of global warming coal burning, car and vehicles and methane gas.
