Greenhouse gas levels have been increasing since the start of the Industrial Revolution, but over the last few decades growth has been particularly fast. Increases in carbon dioxide levels have made the world’s oceans 30% more acidic since the Industrial Revolution. The ocean serves as a sink for this gas and absorbs about a quarter of human carbon dioxide emissions, which then goes on to react with seawater to form carbonic acid. So as the level of carbon dioxide in the atmosphere rises, the acidification of the oceans increases.Over the last century, global background ozone concentrations have become 2 times larger due mainly to increases in methane and nitrogen oxides caused by human emissions.At ground level, ozone is an air pollutant that is a major component of smog which is dangerous for both humans and plants.Long-term ozone exposure has also been shown to reduce life expectancy. 362000-700000 of annual premature cardiopulmonary deaths worldwide are attributable to ozone.Throughout history, humans have existed side-by-side with bacteria and viruses. From the bubonic plague to smallpox, we have evolved to resist them, and in response they have developed new ways of infecting us.We have had antibiotics for almost a century, ever since Alexander Fleming discovered penicillin. In response, bacteria have responded by evolving antibiotic resistance. The battle is endless: because we spend so much time with pathogens, we sometimes develop a kind of natural stalemate.However, what would happen if we were suddenly exposed to deadly bacteria and viruses that have been absent for thousands of years, or that we have never met before?We may be about to find out. Climate change is melting permafrost soils that have been frozen for thousands of years, and as the soils melt they are releasing ancient viruses and bacteria that, having lain dormant, are springing back to life.People and animals have been buried in permafrost for centuries, so it is conceivable that other infectious agents could be unleashed. For instance, scientists have discovered fragments of RNA from the 1918 Spanish flu virus in corpses buried in mass graves in Alaska’s tundra. Smallpox and the bubonic plague are also likely buried in Siberia.Carbon dioxide is in a gaseous state at normal temperatures and its chemical equation is stated as CO2. Many people associate this with the internal combustion engine which powers the modern automobile. In fact, the largest producer of carbon dioxide, in the United States, within the fossil fuel combustion group is the generation of electricity.Transportation comes in second place in the United States for CO2 production levels. Although the burning of fossil fuels happens to be the largest source of CO2 there are also natural causes of the gas within the atmosphere. The breathing of animals, volcanic eruptions, and release of CO2 from the ocean, which happens to be a large carbon “sink”,are all natural causes of carbon dioxide. One of the great parts of our Earth is the natural way it can clean itself. Carbon dioxide is a naturally occurring gas within our atmosphere. Due to this naturally occurring substance, there is a natural way for decreasing the levels of CO2. During this process carbon dioxide is drawn in through the leaves and stored within the main mass of the plant/tree. The carbon is then drawn into the soil through the roots of the agricultural crop or tree. This is nature’s way of drawing the carbon dioxide out of the air and into the ground where it can be stored. Even though the carbon dioxide is being released into the air again this is how nature self-regulates the CO2 on its own. The CO2 emissions today are higher than natural amounts due to the burning of fossil fuels as previously mentioned. Technology will help us to develop machines and devices to reduce the emission of carbon dioxide from the burning of fossil fuels. However, currently, we do not have the technology to completely eliminate the gas from our emission list. In order to reduce CO2 emission levels action must be taken to enhance a device in the exhaust of modern machinery. New technologies could also be introduced to various other parts of the combustion process in order to make it more efficient. The more efficient a combustion process is, the less fuel will be needed and therefore less CO2 will be produced from that running engine. A great way of reducing the carbon dioxide levels would be to switch over to a different type of fuel energy in order to receive the same amount of work time, or more, with less maintenance. One method of reducing CO2 levels is to use Carbon sequestration. During this time there weren’t any regulations on carbon dioxide levels emitted from production plants. Therefore plants back then were producing large amounts of CO2 and nobody thought anything of it until testing was done at a later date. This proves that the industrial revolution along with current fossil fuel burning has produced mass quantities of CO2 and placed the gas into the atmosphere. The increase in carbon dioxide in our atmosphere is said to have been a contributing factor to the “global warming” effect. CO2 is named a greenhouse gas along with other gases such as methane and nitrous oxide. These retain heat and emit it at the same time. Elon Musk, co-founder, and owner of Tesla has created a legacy for himself and his company. Not only are his cars sleek looking and incredibly fast, they are also one-hundred percent electric. This means that the vehicle uses no fossil fuels or other dirty fuel sources to power itself. In fact, the cars main battery can be swapped out for other batteries, which can be larger or smaller than the one provided. The battery can also be recharged with solar energy . Global warming is increasing day by day because of the continuous increase in the levels of greenhouse gases. A vast increase in the temperature, sea level, and weather patterns has been seen clearly in few last decades. All the changes because of the ever-increasing global warming are not a coincidence however it is caused by the human activities and technological advancement. A little fluctuation in the level atmospheric carbon dioxide may cause a high-level significant effect on the global temperature. The continuous rise in the percentage of atmospheric carbon dioxide is alarming us by its dangerous effects however we are still ignoring. Increasing need for fossil fuels by the people of industrial civilization is giving the opportunity to rise in carbon dioxide emissions.Deforestation is also causing an increase in the carbon dioxide through decreasing number of plants and exposing soil to the sunlight. Trees are the best source to absorb CO2 from the atmosphere however what happens if we finish the main source of reducing the CO2 level. Our malpractices just to live a luxurious life on a daily basis are hugely altering the environment as well as endangering the lives of people in return. A little rise in the level of greenhouse gases may hugely affect the global warming.
