Co2 Levels Are Changing Essay

The rapidly increasing amount of carbon dioxide may be one of the factors that cause climate change. As Hillman states, “Concentrations of carbon dioxide in the atmosphere are increasing, and have done so since the Industrial Revolution.” An atmospheric CO2 concentration, research shows that there is a dramatic increase from 280 parts per million (ppm) in 1750 to 373 ppm in 2002, a rise of the third. Furthermore, the linear chart demonstrated the trend of annual global CO2

Climate Change- Climate is a long term change in the Earth's weather, especially due to an increase in the average atmospheric temperature. According to research, it was discovered that the Earth's temperature rose by 0.6 degrees Celsius (C) and predicted that the sea surface temperature may rise by up to 1 degrees C over the next 50 years. Unfortunately, carbon dioxide and methane gas levels are the highest they have ever been for the last 420000 years. These two gases with water vapour, nitrous oxide and halocarbons create the five predominate greenhouse gases, effecting the environment greatly. Furthermore, it is evident that an average person release 4 metric tonnes of carbon dioxide per year. Due to this fact, carbon dioxide

Over the years Carbon Dioxide has been significantly increasing from human activity. CO2 has a concentration of about 400 ppmv (parts per million volume). Its concentration in the atmosphere was about 280 ppmv before the Industrial Revolution, now it has increased immensely to about 380 ppmv in 2006. Many have said Carbon Dioxide has been the main reason or cause of global warming; saying that if we produce too much of this greenhouse gas it can create a global climate change. Even though carbon dioxide affects the temperature of the atmosphere it also affects the acidity of water specifically in the ocean.

(Transition – I will begin by discussing the increase of carbon dioxide into the atmosphere and how humans have made it one of the main causes of climate change.

Over the last several decades, climate change has evolved from a polarizing discussion to what will likely be the largest collaborative research project of our generation. While many aspects of climate change are still misunderstood, there is little debate that the concentration of carbon dioxide in the atmosphere is rising at an alarming rate. This rise is considered the main cause behind an increase in global temperature, which has set in motion a chain reaction of climatic events.

. In unit 2 we learned that climate change is caused by CO2 (Carbon Dioxide).This layer of greenhouse gas is trapped into the atmosphere and increases the thickness of the layer. As a result it rises the Earth’s temperature warmer and causes climate change. The CO2 is caused by human activities such as pollutions and burning fossil fuel. The risk of climate change is extremely high such as loss of the major ice sheets and sudden changes in the

Human beings have increased the CO2 concentration in the atmosphere by about thirty percent, which is an extremely significant

Secondly, together with deforestation of the planet, the burning of fossil fuels is contributing to a measurable increase in the concentration of carbon dioxide in

Climate change or colloquially known as global warming, now pose a new threat to civilization as the levels of greenhouse gases (GHG) are soaring to new levels. The most significant contributor to greenhouse gasses would be Carbon Dioxide (Co2). The levels of Carbon Dioxide (Co2) gas have risen to levels civilization has not seen before. As such, the effects of these levels are not known to civilization as data gathered from the ice cores drilled in the Antarctica only shows data up to 650,000 years ago. However we can conclude that present CO2 concentrations are higher compared to any time in the last 650,000 years (IPCC 2007). Current carbon dioxide concentrations are hovering around 389 parts per million (ppm) as of September 2011,

The concept of climate change has been around for quite a while. The earliest mention of climate change dates back to the 19th century. Swedish scientist, Svante Archenius was the first scientist to study the effect of CO2 on climate. (Rodhe et al 1997)

The main effect of climate change on our oceans, apart from temperature increases, is acidification—that is, an increase in the acidity of the water (or a decrease in its pH). And the cause of this increase in acidity is the same CO2

Today, atmospheric CO2 concentration has nearly increased by 25 percent, and the global temperature has risen by nearly 1.25 degrees as reported in 2014 (U.S. Global Change Research Program, 2014), as part of a continuous rise since the 1800s. This may seem small but are having a huge effect on the Earth and causing global warming, and in turn, climate change. These changes are predominantly blamed on humans, through actions such as fossil fuel consumption, deforestation, and increased agricultural production and

Climate change has been a widely debated, controversial topic. Some think that it is not an issue that should be payed much attention to. With climate changing being caused naturally and by humans, the climate has been widely changing due to ample amounts of CO2 emissions. Where the burning of fossil fuels is the main source of the human impact. As well as volcanoes being a majority the of natural emissions. Although nature contributes to the climate change humans have more widely contributed to the change of climate abroad.

As carbon dioxide is a greenhouse gas, increased concentrations of it have led to an amplified greenhouse effect. More solar infrared radiation is re-emitted and absorbed by the Earth, causing surface temperatures to rise. Therefore, the density of the surface waters will decrease, which means there is a greater

• Carbon dioxide (CO2) is a greenhouse gas that warms the atmosphere. • Since pre-industrial times, atmospheric CO2 concentrations have increased from about 280 parts per million (ppm) to over 380 ppm. Current concentrations of CO2 and other greenhouse gases are unprecedented in at least the last 650,000 years, based on records from gas bubbles trapped in polar ice. • Independent measurements demonstrate that the increased CO2 in the atmosphere comes
