11th Hour Research Paper

Climate change will cause the air in the arctic to get warmer which melts the permafrost in the ground. The Sea ice will melt due to higher temperatures of the air and ocean, ending in rising sea levels and the melting of glaciers. You might think we have lots of time before this happens but in reality each year we lose about twice the size

Economic growth is vital to sustain human life; however, the unsustainable consumption of natural resources to attain this demand is leading to self-destruction. The Earth is facing environmental changes, including climate changes, which are altering the Earth system. Significantly higher thermal expansion is inescapable if the increasing pollution by carbon dioxide emission continues relentlessly. One evidence of this change is global warming and its impact in the Arctic Ice. The critical role of the Arctic in the global climate system implies that Arctic Ice changes will have far-reaching connotations for, and feedbacks to, the entire Earth. Currently, the warning signs include: rapid diminishing of sea ice, increased mass

12 hours. At the time, it seems like such a long trip. 12 hours on the road. Little did I know that in those twelve hours I would come to place that would change my outlook on life.

The change the Artic will have an impact on the earth. Temperatures in the Arctic are rising at twice the rate of the rest of the world on average, and melting glaciers and land-based ice sheets are contributing to rising sea levels. Rising ocean temperatures are affecting ocean ecosystems. In turn having an affect on the communities and economies that depend on them. The changing Arctic could lead to global changes in ocean-based food security that will place additional burdens on economies, societies, and institutions around the world.

It has been observed through various researches that in the last century, average temperatures across the globe increased by over 1.3°F with an increase of more than two times in the Arctic. (Bates, Kundzewicz, Wu, & Palutikof, June 2008). The results of climate change can also be seen in changing precipitation patterns, increases in ocean temperatures, changes in the sea level, and acidity and melting of glaciers and sea ice (USEPA, 2014).

Altogether, the author effectively shows the damages that climate change causes on the Arctic Ocean. This includes changes in the water’s components, the loss of marine life, and rising oceans. The author is also able to show how imminent these problems are today, and that this is not just a topic for the future. This topic is important because the world’s emissions of greenhouse gases is hurting the ice caps exponentially, which will cause a ripple effect of harmful

In the Ian Eisenman, Tapio Schneider, Davis Battisti, and Cecilia Bitz’s article “Consistent Changes in the Sea Ice Seasonal Cycle in Response to Global Warming”, published in Journal of Climate, authors describes and illustrates how global warming affect arctic ice. Authors explain that even though, changes in distribution in ice on both hemispheres of earth looks different it is only due to geological factors. However, in conclusion, the rate of withdrawal of the ice is drastic on both hemispheres, and it is mostly due to global warming.

` Countless of people across the United States and around the world are unaware of what climate change is. It can be a change in the Earth’s climate, a change in the Earth’s usual temperature, or a change in where snow and rain descend. Climate change all the way from the Arctic can affect us in different ways. It can alter global climate and precipitation patterns. It can affect Arctic species, which can be felt globally. It can also increase global sea levels.

The piece of some the assigned reading that interest me the most is the effect of greediness and behaviors impacting the environment. As such, in ‘Eco Defense”, however the writer pointed out the imperative for one’s to take action to preserve the environment. Addition, in “The call of Wild” the author highlights the behaviors of humankind destroying everything; such as, earth and naturel resources, and as well as animals, trees and plant are being affected by the disruption of the human. Basically my topic will be on the environment and what other aspect that are destroying the planet and also what can be done to educate the new generation about it. Not only I believe it is a patriotic thing to preserve the planet and also believe that it

Artic ice melts each summer and refreezes each winter, this a natural thaw – freeze cycle, but in recent years this cycle has been greatly affected by global warming. Summer ice has been melting much more rapidly, which affects the average thickness of the ice. This also changes the ocean’s albedo drastically. It no longer reflects the sun’s energy, but rather absorbs it due to its dark, open waters. This is the beginning of a very destructive cycle: the loss of ice leads to the warming of the ocean which in turn leads to more ice loss. The thinning and eventual loss of ice can have major effects on regional temperatures. This can cause shoreline erosion which would force thousands of locals to relocate to higher ground. It would also cause great damage to natural resources and habitats.

As the Earth keeps warming, the Arctic's summer sea ice is vanishing at a stunning pace. This rapid melt is expected to have significant environmental and health consequences for the entire world, including sea level rise, affecting agriculture, endangering water and food security, erosion of coastal habitats, increasing intensity of natural disasters, and species extinction. Countries have since responded to climate change by adapting to its impacts and acceding to various international treaties such as the Kyoto Protocol to mitigate green house gas emissions, thereby reducing the rate and magnitude of change.

Many problems result from global warming. One of the biggest problems is how much rise in sea level there has been. The rise in seal level could result in the flooding of low costal areas and cities. Ice on Greenland and along Antarctica is disappearing too. Climate models did not predict the shrinking of the sea ice in the Artic Ocean in in more recent years. Attempting to figure out what was happening, scientists have been charting, by satellite and ground measurement, glaciers in Greenland. They also have been sending probes under the Antarctic ice shelves. A Glaciologist in Greenland watched a lake of melt water get drained through a crack, 3000 foot thick, ice. It was powerful enough to lift the massive glacier off the bedrock and slide it into the ocean at a very fast speed. The data shows that the huge glaciers slide into the sea has increased from one meter a day to about 15 to 20 meters a day. Along the coasts of Antarctica and Greenland, large ice shelves are collapsing, showing how unstable they really are. The ice shelves act as supporters, as they hold back the ice that is grounded on the ocean floor and glaciers

In the last 40 years ocean temperatures have been rising constantly. The vast masses of water store high amounts of excess heat energy (~93%) and in the past 40 years the temperatures up to a depth of 700m rose up to 0.44°C in the first 75m and about 0.06°C in 700m depth. There is data from expeditions dating back to the 1870s that show observable changes in ocean temperature since then. Once of the most important aspects about increasing surface temperature of the oceans is the consequences warmer water has for floating sea ice.2In general, the amount of sea ice in the Arctic and Antarctic has decreased dramatically. It is said that within the twenty-first century there will be sea ice free summers in the Arctic. The melting of sea ice causes sea levels to rise, currently with a rate of about 3mm every year,

The most significant event to indicate climate change is the melting of the polar ice caps. The area of sea covered by the Arctic ice at the North Pole has shrunk by 10% in recent decades, and the thickness of the ice above the water has decreased by about 40%. On the other side of the world, the ice sheet above the Antarctic continent has become unstable. Glaciers are retreating all around the world. Since 1979, glaciers in the European Alps have lost about one-fifth of their volume, and the loss rate has clearly accelerated since the 1980s.

Warming of the climate system is unequivocal. Since 1950’s many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, and sea level has risen. Additionally most of these climate changes are due to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate. The signal of climate change include rise of sea level, surface temperature rise ,glacier retreats, shrinking ice sheets, warming of ocean ,declining artic sea ice ,increase in Antarctic sea ice ,increase in extreme events ,decrease in the amount of snow of snow and ice ,increase in concentration of CHGS.Each indicator described below has been extensively studied over the past several decades, and was captured from many different data sets and technologies.
