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 FAQ - What Causes Global Warming? - 0 views

  • Question: What Causes Global Warming?Answer: Scientists have determined that a number of human activities are contributing to global warming by adding excessive amounts of greenhouse gases to the atmosphere. Greenhouse gases such as carbon dioxide accummulate in the atmosphere and trap heat that normally would exit into outer space.
  • driving cars, using electricity
  • While many greenhouse gases occur naturally and are needed to create the greenhouse effect that keeps the Earth warm enough to support life, human use of fossil fuels is the main source of excess greenhouse gases. By driving cars, using electricity from coal-fired power plants, or heating our homes with oil or natural gas, we release carbon dioxide and other heat-trapping gases into the atmosphere. Deforestation is another significant source of greenhouse gases, because fewer trees means less carbon dioxide conversion to oxygen.

Climate Change Facts - An Introduction | NRDC - 0 views

  • Carbon dioxide and other global warming pollutants are collecting in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up.
  • over the past 50 years the average global temperature has increased at the fastest rate in recorded history
  •  
    Carbon Dioxide and other harmful things are piling up in our atmosphere. The bad gases are causing the global warming. Apparently, the temperature could be from 3-9 degrees higher by the end of the century.

Little Change in Opinions about Global Warming | Pew Research Center for the People and... - 0 views

  • Views about the existence and causes of global warming have changed little over the past year. A new Pew Research Center poll finds that 59% of adults say there is solid evidence that the earth’s average temperature has been getting warmer over the past few decades. In October 2009, 57% said this.

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.

Are humans responsible for global warming? - Debate.org - 0 views

  • Humans are incresing polution which is harming our planet by making global warming more usual
  • There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity, such as the burning of fossil fuels and changes in land use, including agriculture and deforestation.
  •  
    This is a opinion that demands that we ARE responsible for global warming.

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.)

Global Warming Facts, Causes and Effects of Climate Change | NRDC - 0 views

  • When it comes to connecting the dots between climate change, extreme weather and health, the lines are clear. The earth is saying something with record heat, drought, storms and fire. Scientists are telling us this is what global warming looks like
  • Climate change will have a significant impact on the sustainability of water supplies in the coming decades. A new analysis, performed by consulting firm Tetra Tech for the Natural Resources Defense Council (NRDC), examined the effects of global warming on water supply and demand in the contiguous United States. The study found that more than 1,100 counties -- one-third of all counties in the lower 48 -- will face higher risks of water shortages by mid-century as the result of global warming. More than 400 of these counties will face extremely high risks of water shortages. Read more »

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.
