Jim Thomson an oceanographer from the University of Washington has made a remarkable correlation between waves in the Arctic Ocean and global warming. According to Thomson the increasing wave size that he documented during a storm is because of the increasing open ocean (University of Washington, 2014.). The open ocean in the Arctic a decade ago was only 100 miles, but in 2012, it was documented at more than 1000 miles (University of Washington, 2014.) With more open ocean, the normal harsh winds, and warmer temperatures it is predicted that wave sizes will increase. Currently, Thomson measured storm waves reaching sixteen feet and it can only be concluded that waves will increase in size (University of Washington, 2014.). The open ocean impacts the wave size because as wind blows across the surface the water will ripple and create white caps, which will steady double in size, and because of more open ocean the waves will keep getting bigger. This is a problem because as shipping companies look for ice-free routes they will face more stormy ocean weather, which is the leading cause of death on the ocean waterways. …show more content…
Because of increasing Open Ocean it does not only impact shipping companies, but the environment (University of Washington, 2014.). The environment is not only losing glacier ice from increasing temperature, but also from waves battering the face of glaciers, which will break down the summer ice, which will in turn create more Open Ocean. The problem is that as the temperature rises the more glacier ice is melted in the Arctic Ocean. It’s a cycle that has no end unless a deep freeze, ice age, manages to reconstruct the
It is an unquestioned fact that the climate is changing. There is abundant evidence that the world is becoming warmer and warmer. The temperature of the global land average temperature has increased by about 8.5 degrees centigrade from 1880 to 2012 (Karr, et al 406). The one or two degrees increase in temperature can cause dramatic and serious consequences to the earth as well as humans. More extreme weather occurs, such as heat waves and droughts. The Arctic Region is especially sensitive to global climate change. According to the data in recent decades, the temperature in the Arctic has increased by more than 2 degrees centigrade in the recent half century (Przybylak 316). Climate change has led to a series of environmental and ecological negative
It is predicted that the effect of permafrost melting will be that the ocean levels will rise and will significantly increase the temperature and accelerate the rate at which global warming occurs. Permafrost covers 24% of the land in the Northern Hemisphere (Insert Citation), if this was to melt 1700 gigatonnes of methane and carbon dioxide (Insert Citation), powerful heat trapping gases, would be released into the atmosphere increasing the amount of greenhouse gases by 200%.
First, global warming has an immense impact on Arctic Sovereignty as the rise of greenhouse gases thrive in Canada along with other countries. Within 20 years, the polar ice caps of the Arctic have melted twice as fast compared to before. The loss of Arctic ice can furthermore pose a threat to shipping, as navigating the Arctic becomes increasingly challenging. Finally, climate change threatens the extinction of numerous animal species, namely the polar bear. Hence, global warming poses a major challenge to Arctic Sovereignty and Canada along with other members in the Arctic Council must prevent it.
People are responsible for higher carbon dioxide atmosphere emissions, while the Earth is now into the Little Ice Age, or just behind it. These factors together cause many years discussions of the main sources of climate changes and the temperature increasing as a result of human been or natural changes and its consequences; even if its lead to the global warming, or to the Earth’s cooling. In their articles, “Global Warming Is Eroding Glacial Ice” by Andrew C. Revkin and “Global Warming Is Not a Threat to Polar Ice” by Philip Stott, both authors discuss these two theories (Revkin 340; Stott 344). Revkin is right that global warming is taking place. Significant increase of carbon dioxide in the atmosphere is due to human activities combined with natural factors such as volcanic emissions and solar radiation – all together they lead to climate changes and temperatures rising. At the same time, other factors such as deforestation contribute to environmental changes for some glaciers not less than air pollution. However, during global warming not all regions of the planet are affected in the same way, local warming and cooling are both possible during these changes.
While it is hard to directly connect Hurricane Sandy to global warming, it is clear that warmer waters and increased sea level contributed to the severity of the storm. Higher sea levels increase the chance that hurricane winds will bring more water on land and storm surges that reach further inland. The Atlantic region is already experiencing sea level rise, and globally this trend is expected to continue. Ocean temperatures are also on the rise, an...
90 percent of the effects of global warming are attributed to rising temperatures and heat. This heat tends to affect our oceans due to the ...
Global warming is a major concern among the study of biology. Global warming will lead to drastic changes to Earth. There are so many problems that global warming affects, but the one thing that may be overlooked at times is how global warming will affect local farms leading to a decrease in food supply. New Jersey farms will become greatly affected by global warming causing decrease in food supply in the Mid-Atlantic. At the rate the Earth’s temperature is changing, many people locally will experience differences in the amount of food that is available.
Climate change has drastically increased the amount of Arctic ice that melts each
These emissions have caused the Earth's surface temperature to rise, and the oceans absorb about 80 percent of this additional heat. Therefore Woodard states, “...the glaciers in this area drain the West Antarctic Ice Sheet, a precariously balanced portion of the southern ice cap that contains enough ice to raise sea levels by 20 feet…”, which means higher temperatures caused by global warming have led to diminished snowfall due to later winters and earlier springs. This imbalance results in a significant change to ocean evaporation; inevitably, causing sea levels to rise.Rising seas will push hundreds of millions of people live in coastal areas to new areas leaving the grounds that will become progressively vulnerable to flooding. In relation to Hinrichsen by stating, “ In the United States, studies suggest that up to 43 percent of remaining coastal wetlands would be submerged, mostly along the Atlantic and Gulf coast”. Rising seas will push hundreds of millions of citizens that live in coastal areas to new areas leaving the grounds that will become progressively vulnerable to flooding.. Consequently do to soaring water quantity, there will be an increase flood threats everywhere near the coast line, prompting flash flooding during extreme natural disasters. This will cost millions more of taxpayers money to fix damages and destruction. Rivers and lakes exposed by saltwater will contaminate the freshwater , affecting runoff, drinking water, and triggering death to native freshwater fish. Not only can increasing water volume damage properties, it can also alter weather patterns. Increasing temperatures and melting ice in the Arctic regions are creating more snowfall in the autumn months at lower latitudes, which affects an atmospheric pattern that leads to colder winters. As stated by Hanses ”... increasing
If the global temperature continues to rise at its current amount per year, the world could see an increase of about 2°C (3.6°F) (Osborn) resulting in devastating effects. Due to the sudden changes (geologically time speaking) in the temperature there have been some already observable effects in the climate. The Arctic has seen major changes in the amount of ice present in its oceans as well as changes in the icy composition of the Antarctic.
Other effects of ocean warming are it affects the mortality of animals, interference with their breeding ability and it can also lead to the extinction of fish which cannot survive in deep water and are in fewer numbers. Even though the deep ocean waters' is not increasing, they will continue to increase even after the global warming has decreased. This means its effect on the whole ecosystem will still continue and will have an impact on benthic communities in the deep sea. There will be a change in food composition, quality and quantity. Will affect many fish communities, depletion of oxygen, the decrease in biodiversity and increase in sea level threatening the lives of many people living in the coastal region.
With temperatures steadily increasing, glaciers and ice caps will soon melt and in fact already are melting. If all the polar ice caps and glaciers in the world were to melt, sea levels would rise drastically covering numerous cities and towns. All the production and all the hard work would literally drown because of our own
They say that warmer waters will increase the power of tropical storms such as hurricanes and typhoons. Again the statistics given are made by a select group of notoriously bias paid scientists. Meaning the waters won’t get warmer. The waters get warmer every year because of the natural warming and cooling of the earth’s environment. This is the way that the earth works because of the shape and rotation of the earth around the sun. Added on to that is the fact that the storms that have been forming nowadays have been the same size as always just in new locations. This is just one e...
The glaciers are melting hundred times faster than anytime in history. Causing sea levels to rise between 7 and 23 inches by the end of the century. While global temperatures continue to rise the ocean will get warmer impacting sea life. For example, squid and tuna have migrated up to the Northern Pacific because water here in Southern California are not as cold as they use to be to keep them alive. Salmon is about to be affected if northern Pacific if water continues to get warmer. Over the years researchers have seen a decline of penguins have fallen from 32,000 to 11,000 in 30 years.
One of the major effects of global warming is the rise of sea level due to thermal expansion of the ocean, in addition to the melting of land ice. Now there are dozens of land areas that sit well below sea level and the majority of those land areas are very well populated. At least 40 percent of the world 's population lives within 62 miles of the ocean, putting millions of lives and billions of dollars ' worth of property and infrastructure at risk. (Juliet Christian-Smith, 2011) This means if the sea level rises to the projected level of 25 meters (82 feet) half of the world will retreat back to the ocean. (Rohrer, 2007) Also rising sea levels means higher tides and storm surges riding on ever-higher seas which are more dangerous to people and coastal inf...
