HowStuffWorks "If the polar ice caps melted, how much would the oceans rise?" - 2 views

  • You may have heard about global warming. It seems that in the last 100 years the earth's temperature has increased about half a degree Celsius. This may not sound like much, but even half a degree can have an effect on our planet. According to the U.S.
  • But the rising temperature and icebergs could play a small role in the rising ocean level. Icebergs are chunks of frozen glaciers that break off from landmasses and fall into the ocean. The rising temperature may be causing more icebergs to form by weakening the glaciers, causing more cracks and making ice mo­re likely to break off. As soon as the ice falls into the ocean, the ocean rises a little.
  • The main ice covered landmass is Antarctica at the South Pole, with about 90 percent of the world's ice (and 70 percent of its fresh water). Antarctica is covered with ice an average of 2,133 meters (7,000 feet) thick. If all of the Antarctic ice melted, sea levels around the world would rise about 61 meters (200 feet). But the average temperature in Antarctica is -37°C, so the ice there is in no danger of melting. In fact in most parts of the continent it never gets above freezing.

  • There is a significant amount of ice covering Greenland, which would add another 7 meters (20 feet) to the oceans if it melted. Because Greenland is closer to the equator than Antarctica, the temperatures there are higher, so the ice is more likely to melt.
  • But there might be a less dramatic reason than polar ice melting for the higher ocean level -- the higher temperature of the water. Water is most dense at 4 degrees Celsius. Above and below this temperature, the density of water decreases (the same weight of water occupies a bigger space). So as the overall temperature of the water increases it naturally expands a little bit making the oceans rise.

    the temperature of the world has increased .5 degrees Celsius over the last 100 years. The heat is melting the icebergs. The sea levels have risen 15-20cm over the last 100 years.90% of the world's ice is in Antarctica.

Global Warming, Arctic Sea Ice, and Climate Feedbacks | Duke Dean's Blog: The Green Grok - 0 views

  • There are lots of reasons to be concerned about this trend, not the least of which is the amplification of global warming through a positive feedback. (Since ice is a lot more reflective of sunlight than ocean water, melting sea ice allows more heat from the Sun to be absorbed instead of reflected, causing temperatures to rise more rapidly, thus melting more ice, and so forth, creating a positive feedback and raising the Earth’s reflectivity, also known as its albedo.)

How Does Global Warming Affect Animals - 0 views

  • Animals become affected by global warming due to changes in their habitats caused by changes in climate.
  • The changes in temperature caused by global warming will have a number of effects on the habitats of animals. The melting ice will cause the loss of habitat for species such as the polar bear. Warmer water will also cause the population of fish such as trout and salmon to decline.
  •  
    Temperature is one f the main causes of global warming. Animals can loose there homes. Apparently warm water can cause the death of fish or any kind of sea animal.

Global Warming: News, Facts, Causes & Effects | LiveScience - 0 views

  • Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. There is great debate among many people, and sometimes in the news, on whether global warming is real (some call it a hoax). But climate scientists looking at the data and facts agree the planet is warming. While many view the effects of global warming to be more substantial and more rapidly occurring than others do, the scientific consensus on climatic changes related to global warming is that the average temperature of the Earth has risen between 0.4 and 0.8 °C over the past 100 years. The increased volumes of carbon dioxide and other greenhouse gases released by the burning of fossil fuels, land clearing, agriculture, and other human activities, are believed to be the primary sources of the global warming that has occurred over the past 50 years. Scientists from the Intergovernmental Panel on Climate carrying out global warming research have recently predicted that average global temperatures could increase between 1.4 and 5.8 °C by the year 2100. Changes resulting from global warming may include rising sea levels due to the melting of the polar ice caps, as well as an increase in occurrence and severity of storms and other severe weather events.
