Many animals in Antarctica are dependent on ice, but as temperatures increase and ice melts, their populations decrease. There are many ice-loving penguins that are predicted to either drop dramatically in population or even go extinct, but this will allowed for open-water penguin populations to increase. To conclude, the environment of Antarctica is dependent on how the temperature changes, but no matter what, it will change with the temperature and changes will
The Earth’s average temperature has risen 0.6°C, while areas in the Arctic have risen up to 3.0°C in the last 20th century (Gardiner, 2008). Increasing temperatures have already caused changes in the Arctic such as; sea ice covering the Arctic has decreased in area and thickness due to melting of ice and snow, the warming of permafrost, snow cover area has also decreased, and ice on the rivers will freeze later during fall and break up earlier in spring. But why are these Polar Regions more vulnerable to climate change? This is due to the light colour of snow and ice and high albedo, which reflects the solar energy back into space. Due to the increase in greenhouse gases less solar energy is reflected back into space and more solar radiation is absorbed by the Earth causing the increase in ice and snow melting (Main & Ahlenius, 2011).
It would change our climate, but it would not bring us close to the level of uninhabitable Venus. A doubling in CO2 levels would make agriculture much more difficult due to shifts in climate that occur as a result of increasing temperature. CO2 can indeed cause a significant degree of warming if it is suddenly released into the atmosphere, as we have been doing for the past 150 years. Aside from that, increasing temperature can also cause the rising of sea level as the glaciers are going to melt at a faster rate like never before. Next, is the change in environmental health.
During this season they mate in the sea and give birth on land or ice floes. Changes in the climate are affecting them just as they are affecting other species in the arctic. Global warming may seem more realistic for a mammal living in the north than it does to humans living in urban regions. Some of the coldest spots on Earth have warmed up and continue to warm up which is resulting in centuries old ice caps melting, rivers running dry, and coasts eroding and as a result, threatening communities[1]. Winters are shortening and sea ice is diminishing at a rate of about 3% per decade.
This in turn has cause the average temperature over the past century to raise about 1 degree, and another 4 degree increase is expected during the 21st century. But average temperatures in the Arctic increased at nearly twice the rate of the rest of the world meaning that a temperature rise of 5 to 9 degrees is expected over land and up to a 13-degree change over the ocean. Also over the past century tidal gauges have shown nearly a 7-inch rise in ocean levels cause by the melting ice. Scientist predict that by the year 2090 the water will have risen 11-inches to well over 3 feet. Due to the actions of man the packed ice that serves as the key part of the polar bear’s existence is being melted away which could leave the great white bear literally out to sea.
Endangered Polar Bear Envision a world with an increased water and food scarcity, stronger hurricanes, melting glaciers, wildfires, rising sea levels, heat waves, and catastrophic effects on wildlife. Global warming is when the earth’s temperature heats up which is caused by greenhouse gases such as carbon dioxide, methane, and water vapor that traps heat and light from the sun in the earth’s atmosphere making it hotter than usual. The effect of the high temperatures leads to a decrease in the existence of plants, animals, and humans. Polar bears were listed as endangered species under the United States endangered species act (ESA) in May 2008. Why are polar bears endangered?
EAP VI/A R/W YUCHENG WAN 11/27/12 Is Global Warming Manmade? Abstract Global warming is caused by numerous activities such as driving, taking airplanes, generating electricity, displaying fireworks, using air conditioning, developing industry and logging because those activities emit so much carbon dioxide that global temperatures rise up. Trees store CO2 in the forest system, so if forests are damaged, much CO2 will be released, which will increase the global temperatures. As this paper illustrates, natural climate cycles have already changed from warm to cool, so global warming is not because of natural factors. The solutions for global warming may include improving the efficiency of energy, protecting forests, producing more energy from renewable sources, generating electricity by wind, traveling in more fuel-efficiently vehicles, riding bicycles and using more efficient electrical appliances.
As Williams E. Rees states in his book “Our Ecological Footprint”. This is shown in the Climate Change view because our pollution results in temperatures rising. Due to this increase of temperatures the Arctic sea ice is melting, glaciers are retreating and sea levels are rising. At the top of the food chain are the producers. In society’s case the producers are the natural resources.
Factors of concern, such as ecosystem composition and pathogen virulence, are said to be related to climate changes. Climate change will have significant effects on wildlife, domestic animal, and human diseases, according to scientists. There is scientific agreement that the world’s climate is changing and that the evidence demonstrates that global warming and climate changes are happening. It is anticipated that continuing changes to the climate will have serious negative impacts on public, animal and ecosystem health due to extreme weather events, changing disease transmission activities, new and old diseases, and changes to habitat that are important to wildlife conservation. It’s very important to know that the majority of recent emerging diseases have a wildlife origin.
The United Nations Food and Agriculture Organization (FAO) “estimates that the annual rate of deforestation is about 1.3 million square km per decade, with the main deforestation occurring in the tropics where a wide variety of forest exist”. (“Deforestation”). Forest provide the planet with a wide variety of benefits, one being the absorption of carbon dioxide. Carbon dioxide is a greenhouse gas that in large amounts has a potential to alter the climate of the earth. With the depletion of the forest that converts the carbon dioxide into oxygen it has monumental negative effects on the planet as a whole.
