It’s rather obvious that human causes are more vulnerable compared to natural causes. Natural causes are normally external to the climate system, such as changes in volcanic activity, solar output, and the Earth 's orbit around the Sun. On the other side, climate change that are caused by human activities, are such as the burning of fossil fuels and also the conversion of land for forestry and agriculture. Not only that, carbon dioxide is also one of the main cause of human-induced climate change. Ever since the Industrial Revolution, the production of carbon dioxide which is a greenhouse gas has been increasing tremendously.
The argument of this controversy is “are humans the main cause of global warming?” “In its 2013 fifth assessment report, the IPCC stated in its summary for policymakers that it is “extremely likely that more than half of the observed increase in global average surface temperature” from 1951 to 2010 was caused by human activity. By “extremely likely”, it meant that there was between a 95% and 100% probability that more than half of modern warming was due to humans.” (Carbon brief). Human activities, such as the combustion of fossil fuels are altering the climate system. Another reason how humans affect the cause of global warming are human driven changes, such as deforestation, urbanization, and shifts in vegetation
Carbon dioxide gas is identified as one of the most important gases that contributed to greenhouse effect. What is greenhouse effect? Greenhouse effect is the trapping of the sun’s heat energy in Earth’s lower atmosphere due to great transparency. It increases the temperature of the earth globally and causing various critical problems such as climate change and melting of polar ice caps. Carbon dioxide is mainly produced by burning of fossil fuel either by cars or factories.
These include volcanic forcing, solar forcing, solar variability and the industrial chemicals. The cause of our current climate change issue is from human beings. Anthropogenic variables is the leading role of climate change today.Climate change currently is caused by the increase of greenhouse gases in earths atmosphere. The increase of greenhouse gases is driven by man made forces. In the industrial revolution the amount of greenhouse gases like Carbon dioxide increased.
An article from the Pre Research Center states that “ 74% say there is solid evidence that the average temperature on Earth has been getting warmer, while 23% say there is no solid evidence that the Earth has been warming” ( “Global Warming and Environmental regulation, personal environmentalism”) This shows that over the years more people in the world believe that there is such thing of climate change and agree that the temperature of the atmosphere has increased dramatically. Many people think they can’t help fix this problem, though they are wrong. Big organizations aren’t the only ones who can help. An individual can take actions to stop climate change, these actions can conclude to “ to help stop climate change, such as driving less, hanging washing on the line instead of using the dryer, using less water, or turning the heating down.”( Heres How You Can Help Stop Climate Change) This shows that not only a group of people, or people with a lot of money can help stop climate change. Individuals can stop climate change by doing a simple
Most climate scientists are agreed on the key parameter of climate change is the increasing amount of greenhouse gas concentration in the air. Solomon et al claimed that even if carbon dioxide emission is stopped now, the effects on climate could be reversed in 1000 years’ time (Solomon et al, 2009). According to NASA statistics, “the atmospheric concentrations of carbon dioxide, methane, and nitrous oxide have increased to levels for many years and concentration of carbon dioxide has increased from 315.71 ppm in 1956 to 398.78 ppm in 2014. Ocean acidification is caused by the absorption of 30% of the emitted anthropogenic carbon dioxide in the oceans (NASA Earth Science Communication Team, 2015). All those evidences have proved that the human factor is one of the major factors in rapid rise of greenhouse gas emissions.
When producing plastic, you need to have petroleum and natural gas. (Macklin, 2016). Petroleum and natural gas are both fossil fuels, meaning that when using they produce an excess of carbon dioxide. Too much carbon dioxide can have detrimental effects on the world including global warming and climate change. The usage of plastic emits between 100-500 million tons of CO2 every year.
To be more specific on climate topics, burning fossil fuel has been the radical basis of our economy since the Industrial Revolution, whereas a fatal impact is destroying our living planet: carbon dioxide is incredibly accumulating in the atmosphere due to the exploitation of fossil fuel. For instance, the chief reason why average temperature on Venus, a sister to our planet, is approximately 15 times higher than it on Earth is that the Venus’s atmosphere has been chock-a-block with carbon dioxide, which is trapping the Sun’s heat (Gore 2008). Nevertheless, what people have been accustomed to do is releasing carbon emissions into our atmosphere, which
Climate change is also caused by land use for two reasons. From 1750 to 2007, about two-thirds of anthropogenic CO2 emissions are produced from burning fossil fuels, and one-third of emissions from changing the lands use, primarily deforestation. Deforestation both reduces the amount of carbon dioxide absorbed by deforested regions and releases greenhouse gases at the same time, mixed with aerosols, through biomass burning and along with CO2, methane and nitrous oxide are also greater forcing contributors to the greenhouse effect. Add the largest contributors of power stations by burning coal, gasoline, and natural gas is diluting the naturally-occurring carbon dioxide in the atmosphere. Data from Trudinger, et al.
Vegetarian is the best way to reconcile with earth How concerned that in this kind of sophisticated era to find our earth getting expired. Global warming is a vital sign of this phenomenon. It is the gradual heating of Earth's surface, oceans, and atmosphere. Scientists have documented the rise in average temperatures worldwide since the late 1800s. Earth's average temperature has risen by 1.4 degrees Fahrenheit (0.8 degrees Celsius) over the past century, according to the Environmental Protection Agency (EPA).
These problems are not going to fix themselves without help the plant will warm up 0.6 celsius without any greenhouse gases influence. According to meteorologists from 1890 to 1990 temperatures have risen 0.72 degrees fahrenheit to 1.26 degrees fahrenheit. In fact through the 20th century global temperatures have rises 1.4 degrees fahrenheit which could lead to surface temperatures increasing. There has been efforts to help with global warming considering from 1998 to 2009 $99 billion dollars have been spent on climate change. Therefore these effects could be substantial.
Natural sources include decomposition, ocean release and respiration. Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas. In 2013, CO2 accounted for about 82% of all U.S. greenhouse gas emissions from human activities. Unfortunately human activities are having a substantial impact on altering the carbon cycle, both by adding more CO2 to the atmosphere and by affecting the ability of natural sinks, such as forests, to remove CO2 from the atmosphere. While CO2 emissions come from a variety of natural sources, human-related emissions are responsible for the increase that has occurred in the atmosphere since the industrial revolution.
Global Warming is the most controversial issue that we face today, because throughout the years we have been releasing greenhouse gases that are harmful in the long run and will affect the future generations. The temperature throughout the twentieth century has been increasing steadily by 1.4 degrees Fahrenheit a year. The cause of global warming is from the release of gases called GreenHouse gasses such as carbon dioxide, methane and several more. Factories ,cars, and other working companies release these gases while extracting fossil fuel from the earth 's crust. Alternatives sources of energy can be implemented because if we keep on using energy that releases these GHG then we might tear up the ozone layer.
