Change In The Arctic Ocean

etc., are released. A substantial amount of carbon dioxide being released into the atmosphere is from the burning of fossil fuels. Evidence acquired from several studies report that since the early nineteenth century, there has been over a 30 percent increase in the carbon dioxide content in the atmosphere.

off the surface, having a reduced amount of ice in the ocean would cause higher temperatures. In

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

For many years now, scientists have believed that our climate is changing. This climate change has caused water currents up north, near Antarctica to shift leading to warm waters taking the place of the usual cold arctic waters. Warm water melts the glaciers and causes the top of the glaciers to float off into the sea, allowing the warm water to melt even more glaciers. The extra glacier melting into our sea has caused the sea levels to raise and the

Climate itself adjusts time to time however recently it’s been noted that it’s been getting warmer more rapidly than expected, which in turn has melted ice sheets in the artic.The change the Artic will have an impact on the earth.

Recent scientific evidence indicates that humans have upset the carbon cycle, leaving more carbon dioxide and other greenhouse gases in the atmosphere. Burning fossil fuels such as oil and natural gas, burning biomass such as ethanol and wood, creating cement and releasing other chemicals into the atmosphere is upsetting the natural flow of carbon.

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.

Global warming has effected the world. The earth has had a drastic and devastating aftermath since humans have decided to release greenhouse gases into the atmosphere. This resulted in the ground (above or below water) temperature to rise; the very definition of global warming. This has warmed up the waters and the fish of the ocean are now living in an environment that is too hot for them to live in.

American environmentalist Jeff Goodell once said, “Some studies suggest that the Arctic Ocean may be ice-free by the end of the century.” The destruction of the Polar Regions has caused major implications for the Earth today and has caused a positive feedback loop that ultimately will cause them to deplete further. The Polar Regions have slowly faded away due to the lack of precautions humans have taken to protect them, such as the use of chlorofluorocarbons, the destruction of the ozone layer, and the accelerated process of the Greenhouse Effect.

As Earth’s surface temperature rises, the ocean also becomes hotter which results in an increase in sea level and decrease in Earth’s ice. “The oceans have absorbed much of this increased heat, with the top 700 meters of ocean showing warming of 0.302 degrees Fahrenheit since 1969” (“Climate Change: How Do We Know?”). Since greenhouse gases are trapping energy from the sun, the oceans absorb more heat which ultimately increases surface temperature. Oceans are able to absorb large amounts of heat energy because water has a greater heat capacity than air. As oceans become warmer, the frozen water on Earth melts at an accelerated pace. The thickness of Arctic Sea ice has dramatically declined throughout the last several decades. “Arctic sea ice

Throughout history, Arctic Ocean has been explored by many nations that put its attention to discover the particular unknown areas. The first explorations of the Arctic started on 330 BC by European marine explorer named Pytheas of Massalia. Pytheas was the first person that recorded the existence of Polar Ice . Since the 12th century, with the increasing of the population and the increment of trade-related activities, commercial routes have had a growing importance and the overseas search for alternative routes has become crucial . On 1594-1960,the driving force for the exploration of the Arctic was the desire of European monarchs to find an alternate route to India and China, either a Northwest Passage along the coast of North America or

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.

Why don’t Oceans freeze. In many parts of the world , winter temperatures drop low enough to make rivers and lakes freeze. In these parts of the world, the ocean will not freeze even though other water sources does. In the Arctic region, most of it is a tundra, which include frozen soil and animals such as polar bears and penguins. The ocean however is not frozen.

     Now that we are aware that global warming is influencing our world’s oceans, we must look at the affects that it is having. I did not find any positive affects of global warming on the oceans. It is sad to say, but I was left with only the negative. One of the effects that warmer temperatures have on the oceans is that they disrupt the ocean circulation rate (Pearce, 1996). As I previously mentioned, oceans must maintain all of its characteristics properly. Warmer temperatures in the atmosphere affect circulation rates in the oceans. If circulation rates in the oceans are altered, then everything in the oceanic environment becomes changed. The oceanic currents become affected, as well.
