Throughout history Earth`s climate has changed a lot, and there is a lot of evidence that shows how humans have contributed to this changed and effected the Earth. Just in the last 650,000 years there have been seven cycles of glacial advances, the increase in the thickness and area of a glacier. As well as glacial retreats, a condition occurring when backward melting at the front of a glacier takes place at a rate exceeding forward motion. Most climate changes are attributed to very small variations in the earth`s orbit, that change the amount of solar energy our planet receives. The 21st century has seen the most temperature records broken in recorded history. 2016 was the hottest year on record since 1880, according to Nasa and the National …show more content…
Human activities contribute to climate change by causing changes in Earth`s atmosphere in the amounts of greenhouse gases. Since the start of the industrial era (about 1750) the overall effect of human activities on climate has been a warming influence. The United States is the second biggest contributor of CO2 in our environment, however it is home to only 4.4 percent of the total population. In the event that everybody on the planet lived the way individuals do in the U.S., it would take four Earths to give enough assets to everybody. In many ways over time the effect that humans have on the climate is very bad and very dangerous. Arguably the most significant thing humans have done to cause climate change is the drastic increase in CO2. As a result of human activities, carbon dioxide, methane, nitrous oxide, and the halocarbons (a group of gases containing fluorine, chlorine, and bromine) build up in the atmosphere over time, as well as the natural sources of CO2, like vegetation. The concentration ofCO2 has went from 280 to more than 380 parts per million in just two hundred years. Still currently rising, the burning of fossil fuels by humans will continue to cause global warming and climate
Water rising due to climate change is impacting people by causing islands to get flooded. This causes people to have to evacuate and find new homes, which can cause overpopulation in some cases (Doc G & H). Climate change is also impacting people because of health. The warmer temperatures cause there to be longer pollen seasons since the cold comes later and goes away sooner (Doc E). This makes for miserable and potentially dangerous summers for people who are allergic to pollen (Doc F).
The Earth is melting, and people need to help. Climate change is a regular thing that happens on Earth, but recently, it has changed drastically. " Since 1880, Earth’s average temperature has increased by about 0.8 degrees Celsius. (BGE) This may not seem like much, but scientists are worried.
Climate change is an irreversible consequence of the damage we do to our Earth. If we do not change our ways, the global temperature will swell, causing an unchangeable series of events, consecrating detriments onto all the existence upon Earth. In only about 140 years, the average global temperature has increased 0.8 degrees celsius, and the ramification is the irreparable destruction of the place where we and millions of other species live. The most important consequence of climate change is the global increase in temperature and how that is affecting various animal species all over the Earth, the health of humans, and the rapid rise of sea level.
By releasing this gas into the air the natural greenhouse gases increase and cause many effects to happen. Carbon dioxide is also caused by removing natural resources from the land for agriculture. When the Earth starts to warm many other things do to, the ocean will become more acidic and glaciers might partially melt. If the oceans become acidic, fish and other sea creatures will have an unlivable environment. If glaciers start to melt arctic animals that rely on the ice may start to become extinct.
The carbon dioxide levels have risen over the last 10,000 years. CO2 is thought to be the greenhouse gas that causes climate change and global warming. It possibly went up due to the increase in the population. Since we breathe in oxygen and exhale CO2. Everything is putting CO2 back into the environment but, at high rates.
Global warming is all about adverse climate change caused by the trapping of greenhouse gases in the earth's atmosphere that affects biodiversity and poses a serious health hazard. Scientists have found strong evidence that human activities have caused most of the warming since the mid-1900 (“global warming”). Humans are responsible for
The things we do like burning coal, oil, gas and even the cutting down and burning of forest fires. Some actions done by higher class individuals, are usually out of the control of an average human, but there is small things we can do. Though the harm we have done to our earth is irreversible, we can work to improve its further state. There is scientific reasoning to back up the fact that humans are the main cause of climate change. People are the causes for the main factors
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.
An even larger source of carbon dioxide is from dying vegetation, such as falling leaves in the autumn. Lastly, Professor Carl Wunsch from the Massachusetts Institute of Technology, studies oceanography and claims that, “The Ocean is the major reservoir into which carbon dioxide goes when it comes out of the atmosphere and where it is reemitted when it comes back out of the atmosphere.” Therefore, if the ocean is heated it tends to emit carbon dioxide and similarity, if the ocean is cooled, the ocean will dissolve more carbon. Therefore, if CO2 caused by humans don’t drive Earth’s climate, what does?
In today’s day and age, climate change is becoming a hot topic. Whether one is an advocate for change or is just skeptical of the entire belief, there is no doubt that this concept is relevant to the modern society. In an article by Robert J. Antonio titled, “Climate Change and Society by John Urry," he evaluates the research of scientist and breaks down the complexities of climate change for the audience. In a separate article by Ashokankur Datta and E. Somanathan titled, “Climate Policy and Innovation in the Absence of Commitment”, the authors evaluate policies concerning the pricing of adapting to more emission-free, healthier technology for the environment. These two articles will be compared and contrasted based on reasons why the public
Heat related illnesses are especially great in the elderly and in young children (Bedsworth, 2009). Those with respiratory and cardiovascular problems are also more susceptible to falling ill because of these illnesses. Air pollution is also a great contributor of climate change related deaths as it kills roughly 3.3 million people a year with 55,000 of those being American lives (Adams, 2015). Hotter temperatures are ideal for the growth of pathogens as they thrive in the heat and ideal for diseases to spread. The warmer climate is also ideal for mosquito and insect borne diseases such as malaria and the zika virus, which currently has no cure (Bedsworth,
Our planet is getting warmer and warmer day by day. According to Statista.com, in 2016 the surface temperature was 0.94 degree Celsius (33.629 degrees Fahrenheit) warmer than the 20th century average. If temperatures keeps going up, then our world could be so hot that it cannot sustain life. Our atmosphere naturally traps heat to make Earth’s climate warm enough to sustain life, the sunlight shines onto the Earth’s surface where it is absorbed and then it is reflected off into the atmosphere. In the atmosphere the greenhouse gases, like carbon dioxide, and methane, trap some of the heat and sends rest into space.
Furthermore, glaciers and ice caps are, and will continue to melt because of this increase in CO2 in our atmosphere. Trees and plants absorb carbon dioxide, a vital element to the growth and nutrition of the plant, however since they are being cleared by humans, the excess carbon dioxide is unable to be absorbed by them. Therefore, creating an above average amount of carbon dioxide in the atmosphere, causing the overall global temperature to increase, which then leads to a warmer climate. Humans have caused a great deal of harm to our planet and all the species that live within it. Most of the excess amount of CO2 in earth’s atmosphere is man’s own fault.
