Atmospheric circulation

The carbon isotope compositions of marine carbonate sediments from the late Paleocene vary significantly, exhibiting a sudden decrease close to the Eocene boundary, which coincides with deep-sea benthic disappearances and with changes in ocean circulation. Such as, life flourished in the Eocene era of…

the additional energy stored in the climate system since 1975 has gone into ocean warming; the remainder has melted the ice, and warmed the continents , occeans and atmosphere. The observed increases in worldwide average surface temperatures and atmospheric carbondioxide have been much faster in recent decadies than the natural changes of previous millennia, and levels are now higher than at an time for hundreds of thousands of years before now. scientific understand of the cause of global…

The four chemicals that are essential for life on Earth are water, carbon, nitrogen and phosphorus. Water is essential for life because it is an excellent solvent. Many different type of material can dissolve in water. Water transport nutrients and waste in and from the human body. Water is also found everywhere on Earth. It can exist as a liquid, solid or gas. Many organisms use water in order to flush toxins anything into and out of a cell. Without water there would be no vegetation on land…

activities, especially in the industrialized process of developed countries caused by economic activities, fossil fuel combustion and deforestation, land-use change and other human-induced greenhouse gas emissions led to a significant increase in atmospheric greenhouse gas concentrations. Between 1906 and 2005, the global temperature increased by 0.74°C. The scientists who from IPCC(Intergovernmental Panel on Climate Change)…

In a 2015 article by Otto Friederike, he suggests that we can relate extreme weather to climate change. Warmer weather has the ability to change the atmospheric circulation and can also start dynamic changes in the atmosphere which cause extreme rainfall. This was shown using the 2012 Krymsk flood as an example, the author states that the extreme event was made stronger due to the a rise in sea temperature. Even…

Understanding oxygen supply and demand while working in the health care field is essential. The tissue cell mitochondria need to have adequate oxygen for metabolic consumption and ATP production. There are limited means of oxygen storage in the tissues; as such a continuous supply of oxygen is required. The respiratory and cardiovascular systems work together to make sure oxygen is delivered throughout the body, and that these continuous requirements are met. Exploring the main role of the…

relative to the holocene period. The holocene period is the only period we know to support human life. The most common greenhouse gases are Carbon dioxide (CO2), Methane (CH4), Water Vapour (H2O) and Nitrous Oxide (N2O). These gases cause increasing atmospheric and earthly temperatures, because they wrap around the earth like a blanket and trap the Suns solar energy, (Solar Radiation) or heat, effectively acting how a glasshouse does. This is known as the greenhouse effect. The natural…

Physiological Effects of Decreased Atmospheric Pressure At lower altitudes such as sea level, the main stimulation for ventilation is carbon dioxide. (7) At high altitudes, hypoxia stimulates ventilation. (7) However, hypoxia only stimulates ventilation when the partial pressure of inspired oxygen is reduced to roughly 13.3kPa, and is at an altitude of 3000m or more. (7) When the inspired partial pressure of oxygen is 13.3kPa, alveolar oxygen pressure is 8kPa. (7) As hypoxia continues to…

and causing more heat absorption in the sea, which resulted in the melting of the ice that creates a positive feedback loop indicating the warming of the sea. The polar heat affects weather worldwide because the atmospheric circulation and ocean current is the control of heat circulation that create a balance on earth. Fueled on the variations of warmth and salinity, this cause the weather patterns at sea and on land to result in more storm. Sea ice acts as insulation between the two the Arctic…

"We need to save the Arctic not because of the polar bears, and not because it is the most beautiful place in the world, but because our very survival depends upon it" (Lewis Gordon Pugh). Anthropogenic contamination and change of the Arctic has been an issue for human civilization for many years, however many people do not believe that humans are the cause of such a difference in this once pristine environment. The activity of humans is primarily responsible for global warming, however, this…
