After the Industrial revolution, global warming has increasingly becoming a threat. Consequently, global warming is becoming a bigger threat that needs to be addressed before even more serious damage is done. “Scientific evidence for warming of the climate system is unequivocal” -Intergovernmental panel on climate change. One of the many questions that scientists and people alike are asking and trying
Risks for infrastructure, risks for ecosystems, risks for fresh water resources and food production, but only steps to build resilient societies can reduce these risks. A few impacts global warming has on the environment are- 1. Physical- It causes an increase in the global mean temperature relative to the pre-industrial levels. Some other effects include global mean sea level rise and ocean acidification causing floods to coastal areas and affecting marine life. Global warming would be irreversible for several millennia.
Mankind has abused nature for far too long and would pay a heavy price unless urgent remedial measures are undertaken. The aim of this document is to take a look at the measures already taken by mankind to reduce the effects of climate change and also suggest additional measure which could be taken by countries around the world after analyzing the current scenario. Author: Commitee on Ecological Impacts of Climate Change Document name: Ecological Impacts of Climate Change Pg 13 Chapters reviewed What exactly is climate change? How does it occur? Climate change can be defined as a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.c Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions.
Many scientists believe that our production of carbon dioxide and other greenhouse gases is having a heat effect on the atmosphere and this could be dangerous for the environment and human life (Hansen, 2011). This article will examine the causes of global warming, its impacts and the remedies we can do to combat global warming. Many problems could result from global warming. Increase in average temperatures could lead to ice melting in both polar ice caps and mountain glaciers. Global warming also bring extreme weather events, causes sea level to rise, increases ocean acidification and causes lakes and oceans to warm rapidly than surrounding environment.
The steady flow of greenhouse gases that traps the rays of the sun. The suns rays heat up the earth atmosphere, and this causes the melting of glaciers at the poles. To support this theory, according to author Melissa Denchak the “According to the National Climate Assessment, human influences are the number one cause of global warming, especially the carbon pollution we cause by burning fossil fuels and the pollution-capturing we prevent by destroying forests. The carbon dioxide, methane, soot, and other pollutants we release into the atmosphere act like a blanket, trapping the sun 's heat and causing the planet to warm.” This shows that due to human advancement in technology we have in a sense changed the environment for the worst. The global
One of the most important problems to this day is global warming. Global warming is the gradual warming of the Earth's surface and the lowest layers of the atmosphere caused by the greenhouse effect, which leads to global climate change. Climate has been changing since the Earth's past, but it is also considered that the current global warming is due to increased emissions of greenhouse gases. The last 100 years have seen the largest increases in temperature over the past 1300 years. People do not know how much they pollute the environment and what catastrophic consequences their actions could possibly bring.
All those evidences have proved that the human factor is one of the major factors in rapid rise of greenhouse gas emissions. Additionally, as the greenhouse gas emission amounts continue to rise, the climate change would cause a change in whole climate system. Limiting or at least being aware of the current condition of greenhouse gases become significant as the consequences become dramatically
When these fossil fuels are burned, they release a gas called carbon dioxide into the atmosphere. These gases trap heat into the atmosphere, in a process known as the greenhouse effect, “which has been attributed to be the major cause of global warming” (“Shift to electric cars”). Global warming is the idea that because of the excessive amount of pollutants being deposited into the atmosphere, the Earth is heating up as a result of the greenhouse effect. While energy production from fossil fuels may have negative impact on the environment, there are alternative ways of producing energy, renewable energy.
Our energy production and use is very much linked with many other aspects of life, such as water consumption, use of goods and services, transportation, economic growth, land use, and population growth. Climate change could affect the amount of water available to produce electricity or extract fuel. In areas where water is already scarce, competition for water between energy production and other uses could increase (epa.gov). Water is an essential thing for human survival. Global warming is threatening and shortening our water sources, drinkable and water bodies.
An increase in the earth’s average temperature is called global warming. It is an adaptation that is believed to be permanently changing the earth's climate. Many scientists are trying to prove that how and why there is an increase in the earth’s temperature. Many greenhouse gases and other human activities are considered to be the foremost cause of global warming. It is really clear that we are not taking a good care of our nature, on which we are dependent.
