A combination of climate change, pollution and search for natural resources is threatening the fragile species and ecosystems within the Arctic region. Over the last two centuries the world's global mean temperature has increased by 0.6 degrees, noting this continuous change in global temperatures is too accelerated for the natural environment to adapt to. Much of this change in global temperatures is the result of c02 emissions being released into the atmosphere. Currently, 80% of the world's growing energy demands are met by the burning of fossil fuels which emit astonishing amounts of c02 into our atmosphere (3). As the name suggests, climate change references the change of the climate, unfortunately this is not limited to the fragile systems of
They also provide evidence that under some circumstances climate can change abruptly. When air is trapped at the base of an ice core and the compacted snow turns into ice, the air is trapped in bubbles. The concentration of greenhouse gases such as carbon dioxide and methane in the layers of ice cores is evidence of how climate has changed in the past, as ice core data has shown that there were high concentrations of carbon dioxide during interglacials and low levels of carbon dioxide during glacials. It also allows scientists to compare modern concentration of greenhouse gases to the past as well as links between past concentrations of greenhouse gases to temperature (Davies, 2015). Data has suggested that when there is a change in carbon dioxide concentration in the surface waters of the ocean this may affect atmospheric concentrations, which could result in the warming or cooling to the Earth’s climate.
To carefully describe the relationship between the rate of reaction and the temperature, a graph of these two variables is plotted. It can clearly be seen that the rate of reaction gradually increases as the temperature is increase. This is best explained by the principles of chemical kinetics. The increase in temperature results in an increase in the kinetic energy of the molecules. Consequently, these molecules are able to move faster and the probability of collusion with other molecules is increased.
Glacial global temperature changes between the ice ages and interglacial periods were due to the concentration of greenhouse gases. Another name given would be called an ice age. The earth also experienced then warmer interglacial periods. When this occurred, flooding happened. Pleistocene creatures had to move to new environments and adapt to their new surroundings or they would go extinct.
Because salt can be dissolved in water, it is said to have high solubility. Sodium acetate also dissolves very easily in water, especially in warm water, so it has high solubility too(1). There are 2 ways to change the solubility of a solution. One way to change it is to raise the temperature because at higher temperatures most solids are extra soluble. The increase of temperature has 2 effects on almost all solutes that are solid.
It is easy to observe that the effect of global climate change on the Earth. For example, the rises of sea levels, glaciers, and polar ice caps are melting; numerous animals are emigrating to find other places to exist; trees are in bloom sooner. Scientists have confirmed that the temperature will keep on rising up for the next decades because of human activities in the industry (Alina). One of the biggest problems facing us now is global warming. It not only affects animals and plants but also the human population, which is indeed scary (Markham).
Arctic life disappearing. You are not dreaming, this could actually happen if the glaciers and the ice capes continue to melt at the speed they are now do to global warming. The main cause of global warming is the Greenhouse effect. This effect is natural and holds certain gases like carbon dioxide and methane and helps the Earth stay warm. The Industrial Revolution was not natural and directly contributed to the Greenhouse effect.
Examinations conclude that a great number of ice shelves are due to disintegrate caused by ocean warming alone. Ocean levels continue to increase at an alarming rate. Glacial melting in Antarctica will have a global impact. Therefore, this is a matter that should be handled by everyone globally. Currently, there appears to be clear control over the climate of Antarctica, assisting in determining what path the continent is on and the direct it leans towards.
As per the latest study shows the level of unfreeze of glaciers are affected from global warming which has been considered permanent. The shrinking of glaciers is pretending a major trouble of drinking water. The brio standards as a total of unfreezing of glaciers have risen from 0.35 mm to 0.40 mm. scholar have warned in their reports, that many glaciers will occult within a period 15 - 25 years. It will create many problems of drinking water and food grains in most of the North American countries.
As a result, less carbon dioxide is removed from the atmosphere resulting in greenhouse gases accumulation and thus, a negative feedback. However, during the Cryogenian period, the earth continents were all at tropical latitudes which slowed down the effect of the negative feedback (Kirschvink, 2002). 5.1 Effect of frozen period on life A global glaciations as tremendous as the one suggested by Snowball Earth theory, would logically eliminate any photosynthetic life on Earth, as a result of the drastically depletion of oxygen. However, it was observed that microfossils such as stromatolites and oncolites have proven that life at marine environments at least did not suffer any mass extinction. Surprisingly, life developed and survived the cold period (Corsetti et al 2003).
Anthony Marr a geophysicist also argues that the increase of Latent heat or Enthalpy will affect the hottest and coldest areas in the world. The event he calls “Latent Heat of Fusion” will rise the temperatures in Antarctic, Artic, and Greenland melting glacial ice. As the ice melt the surrounding waters become warmer which may play a big role in the way future climate change unfolds. This is threat to wildlife which depend on the freezing temperature for survival. This may also cause rise in sea levels and shifting of the balance of the earth
