Negatives Of Climate Change Essay

Killer whales are starting to hunt animals that polar bears and humans hunt making it more difficult for native people in the North Atlantic to find food. (Higdon et. al. 2009) When an economy is reliant on a particular income and it is taken away, the economy starts to collapse and that is what we see happening in the northern most towns and cities.

(Goldenberg, Suzanne.) The bears at risk are a sign of something wrong in the Arctic marine ecosystem. Climate change and the lost of sea ice habitat is the greatest threat. They now have fewer opportunities to feed. They rely on sea ice to hunt and store energy for summer and fall, when food can be scarce.

El Niño’s have been occurring for about 10,000 years since the last Ice Age. When an El Niño occurs it decreases the rise of cold water off the coast of the Americas. “When this happens the fish either die or migrate into areas that they will find more to eat” (wildlife.ca.gov). When this happens in the in the Pacific close to the Ecuador the Galapagos fur seals struggle to find food. When the fish are gone the wildlife that depend on them for food will die also.

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.

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

If the climate change would be the same in the future, the Mount Kilimanjaro 's glacier would likely be to disappear in the next decade. Disappearing of the environment from sea life animals would be the next affect. The polar bear and the walrus are 2 of the many sea life animals who live near ice sheets. Due to the ice melting, these ice sheets are decreasing quickly. Soon there will be no place for them to live anymore.

This conclusion also leads to an upset in tourism and recreational activities. As suggested by the Third R&D Forum on high-density oil spills, "sunken heavy fuel oil may have significant impact on seabed resources and fishing and mariculture activities. " Oil soaked sands and water often result in restrictions from swimming and boating in an area, thus giving people concerns that their heath may be compromised, deterring people from vacationing. Therefore, even hotel and restaurant businesses who make their income from recreational activities and scenery in the coastal

In Wildlife in peril as the Arctic melts). The plants dispersing makes it harder for them to reproduce and grow, and with the plants comes animals that is another contributor to the plant’s demise. Another way the Arctic is changing Is in the sea ice surrounding it. The Arctic’s sea ice is melting at a rapid rate and the damage it is having on the world is almost irreversible. Since 1980 there has been a 30% drop in sea ice which is an alarming number for a short period of time (Kolbert 27).

This issue that I have chosen is the impact of global warming on polar bears. A polar bear major/main threat is due to global warming is the loss of sea ice habitant. These polar bears are marine mammals, which mean they spend most of their time in the sea than on land. The polar bears make their living on the arctic ice. Global warming also has an impact on the population of polar bears (population size decreasing), the sea ice platforms are moving farther apart; which is making swimming conditions more dangerous for the polar bears, it is impacting on their hunting opportunities (fewer), and increased scarcity of food.

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).

The mammoths became extinct because of Climate Change, Human Hunting and Hyper Disease. Over the years global temperature has been increasing democratically, therefore climate change is one of the causes of mammoth’s extinction. Mammoths are large woolly animals that lived in cold climate. According to the Illinois state museum the temperature of the earth

Many, many animals are going endangered and even extinct because of human caused climate changing. One of those notable examples is the polar bears, which only have a population of 20,000-25,000. The reason polar bears are going extinct is because warmer temperatures in the north is causing the ice caps to melt more, and in the summer, polar bears use the ice caps to travel to get food after hibernating. But if the ice caps melt too much and break away, then polar bears

Ocean levels dropped and exposed a land bridge known as Beringia. Siberian hunters used this mass to cross into Alaska and begin spreading into North America, a great milestone. However, the deep freeze did not last and the climate began to warm up. Glaciers melted, the sea levels rose, and the bridge was no longer accessible.

These problems are not going to fix themselves without help the plant will warm up 0.6 celsius without any greenhouse gases influence. According to meteorologists from 1890 to 1990 temperatures have risen 0.72 degrees fahrenheit to 1.26 degrees fahrenheit. In fact through the 20th century global temperatures have rises 1.4 degrees fahrenheit which could lead to surface temperatures increasing. There has been efforts to help with global warming considering from 1998 to 2009 $99 billion dollars have been spent on climate change.

This debris is deposited in what today looks like giant mounds of sand in comparison to the mighty size of a glacier. These mounds are moraines and they are what is left when a glacier melts. They have
