The impact humans are having on mother Earth is increasing its effects with the rising of sea levels. Global warming is causing polar ice sheets to melt, which is a major cause of adding volume to our oceans. Furthermore, the troposphere thickens, due to greenhouse gases, increasing the amount of radioactive waves that causes the seawater to warm up, resulting in ocean expansion. Most climatologists are expecting a rise in oceans around the world to be between 1.5 and 5 ft by the end of this century
many animals are endangered. Ice is the habitat of polar animals because they have to rely on sea ices for resting, food, and reproduction. With the climate change and the decrease of sea ice, the number of polar animals is decreasing and their health is threatened. For example, the average weight of female polar bears in 1980 was about 650 pounds, but the number reduced to about 500 pounds in 2004 (Djoghlaf 15). The earlier breakup and later condensation of sea ice shortens the hunting season of
Alejandra Reyes Tyler D. Watson 10 March 2014 Climate Change: Polar Regions and Marine Mammals As a result of climate change, specifically rising temperatures, there have been increased changes in sea ice and sea level in the Polar Regions. The melting ice creates a positive feedback, more rapidly changing the environment for marine mammals such as pinnipeds and cetaceans. Negative health effects of changes in their environment depend on species sensitivity. Because the most obvious effects of climate
melting ice sheets in the polar region. The Arctic is becoming warmer at a high rate, and contractions in the extent of sea ice are currently changing the habitats of marine top-predators dependent on ice (Prop 1). However, what many people don’t know is that the melting
Polar bears are one of the Earth’s largest and most powerful carnivores. These bears are dependent on sea ice as their primary habitat and are thus found on the Arctic coasts of North America. The scientific term used to describe polar bears, Ursus maritimus translates to sea bear because polar bears spend most of their lives on the Arctic ice. A common misconception the public holds is that polar bears are white; their fur is actually consists of two transparent layers: hollow guard hairs and an
the most well-known is Global Climate Change. However many people refuse to consider the evidence, and continue to peddle ridiculous conspiracy theories. Global Climate Change is not a conspiracy theory because minor climate aberrations, expanding sea ice, and no supporting statistics are all non-legitimate arguments against it. There are copious amounts of evidence to disprove these fallacies. Many conspiracy theorists will tell that because their area is cold, global warming isn’t real. However
the first marine mammal added to the endangered species list attributed primarily to climate change? As climate change melts the ice, it is projected that two thirds of polar bears will disappear by 2050. This drastic decline in the polar bear is occurring in our lifetime, which is but a miniscule fraction of the time polar bears have explored the vast Arctic seas (National Wildlife Federation, 2014). Unfortunately, that is the polar bear (Defenders of Wildlife, 2013). The climate change endangers
The earth’s polar regions are the ice-covered areas located at the northern and southern ends of the globe known as the Arctic and Antarctica respectively. Life in these regions are incredibly difficult thus there are few and specific species living there. The north pole; the Arctic is affected most by the increasing temperatures as it has been proven to be heating up twice as fast as the rest of the world. This heat is therefore resulting in the melting of the ice. The Arctic region is home to the
rainfall and weather patterns. We may not like it but climate change is one of the most important issues that have effects in many parts in our daily lives. If climate change isn’t slowed down it will have a significant impact on global temperature, sea levels, human diseases, and wildlife. Climate change will have an impact on global temperature. Greenhouse gases, emitted by power plants, automobiles, and fossil fuels, are keeping more heat in the Earth's atmosphere. This heat trapping is causing
causes cardio-respiratory diseases in urban areas (Richard, 2009). In summary, climate change has physical and social effects on both human being and animals. The physical effects include increased temperatures, famines, high precipitation, and high sea levels. On the other hand, social effects include low food production due to high temperatures, spread of diseases and many others. The effects are unlikely to reduce unless a quick action is taken to curb the adverse climatic changes. In the wild,
On Thin Ice written by Susan McGrath explains the negative affects of global warming on polar bears. Green house gases being emitted into the atmosphere is causing the earth to become hotter. The ice that the polar bears live on continues to shrink because of rising temperatures. In 1979, there was approximately thirty percent more ice in the summer compared to now. Polar bears spend almost their entire life on the sea ice (McGrath). The only time that they go to land is to build maternal birthing
By: Loriann Malcom There is a long list of endangered animals. On that list is the animal I am currently researching, and that is the polar bear. Polar bears are animals that mostly lives in the North Pole and other ice covered oceans. The mass of an adult female polar bear is 330-350 pounds and an adult male is 990 pounds. Their speed is twenty-five miles per hour and the height of an adult female is 6.6 feet (on hind legs) and an adult male is 4.4 feet at shoulder
Warmer, sea ice-free oceans could also increase melting from Greenland's glaciers. The quicker sea ice loss causes Arctic temperatures to rise, the faster the Greenland ice sheet is likely to melt and while it isn't going to disappear any time soon, this contributes more to sea level rise. According to Carbon Brief, it states, ¨ temperatures rise faster in the Arctic than at lower latitudes, this changes largescale temperature and pressure gradients which has consequences for northern hemisphere
fur is thicker than any other bears' and covers even their feet for warmth and traction Polar bears are marine mammals, and spend much of their time on Arctic sea ice. Many adaptations make polar bears uniquely suited to life in icy habitats. Their fur is thicker than any other bears' and covers even their feet for warmth and traction on ice. Belugas are related to another type of white whale — the "unicorn" whale known as the narwhal. However, instead of a large horn on its forehead, like the narwhal

Alaska is very cold and could get colder.I don’t know how people stay there for that long there's a lot of snow and ice and the water is freezing cold probably.The wind is another thing if you’ve ever
An ecosystem is made up of all the biotic and abiotic features in a specific area, the living correlating with the nonliving, and vice versa. Depending on where the ecosystem may be, organisms may have different relationships with the things amongst them. The tundra ecosystem is an example in this case. Because of its location in the Arctic Circle and its infamous living conditions, organisms use the abiotic and biotic features to their advantage. These kinds of interactions are key to what makes
warming is causing is the melting of sea ice in the arctic. Due to the melting of the sea ice, global temperature suffers. In order to stop the global climate change, the congressional committee on environment must pass a legislation to regulate the use of fossil fuels, because climate change in the arctic is causing all the ice to melt, the permafrost to thaw, and it has huge impact on the vegetation and the wildlife. Over the years the loss of extensive amount of ice serves as the evidence that, arctic
earth’s temperature has risen by over one degree Fahrenheit over the past century, based on land and sea level measurements. The temperature is expected to continue rising at a faster pace over the next century, possibly increasing by as much as seven degrees Celsius. In comparison, the earth’s average global temperature was only twelve degrees cooler than it is now during the last great ice age. A vast majority of species now living do so within a narrow spectrum of temperature ranges and
threats to wildlife and habitat, rise in sea level, and health impacts on humans. One main effect of global warming is the threat to wildlife and habitat. The increase in global warming disrupts wildlife species and causes extinction to animals that cannot adapt (NRDC, n.d.). One example is the decrease in polar bear population. As the ice continues to melt, some polar bears are drowning because they have to swim longer distances to reach the ice sheets. The U.S. Geological Survey has predicted
