Many people believe that Global Warming is a topic that has been used to “scare” the public into living greener. Although there is nothing wrong with wanting people to use less energy and put off less pollution, creating a worldwide problem to benefit your own cause is wrong. The most respected scientific bodies have stated unequivocally that global warming is occurring, and people are causing it. The only real debate is about how fast warming will occur, and how much damage will be done.
As a result of human activities that produce heat-trapping CO2 and other greenhouse-gas emissions. The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by ...view middle of the document...
This surprised researchers, who expected that only the West Antarctic ice sheet would shrink in the near future because the East Antarctic ice sheet is colder and more stable.
In Greenland there are worrisome signs that ice melt is accelerating. In fact, historical evidence and computer models predict that Greenland's massive ice sheet could soon reach a tipping point that would trigger an irreversible meltdown and an eventual sea-level rise of over 20 feet.
Meanwhile, the Arctic region as a whole is warming 2-3 times as fast as the rest of the globe. Since 1979, Arctic sea ice has declined by 11.2 percent per decade. While melting sea ice won't contribute to sea-level rise, it can accelerate the warming that does affect sea level rise. Scientists believe the polar ocean, including the geographic North Pole, could be entirely ice-free in the near future. Their predictions range from as early as 2013 to as late as 2100.
According to Godard Institute of Space Studies (GISS), the years 2000-2010 have been the warmest years on record. Contrastingly, the other three major climate monitoring agencies-the Hadley Meteorological Centre (HadCrut), University of Huntsville at Alabama (UAH) and Remote Sensing Systems (RSS) - all record as 1998 remaining marginally hotter than other recorded years. So how can three agencies say one thing and the other agency come up with completely different numbers? Well according to Paul MacRae’s article “The past decade: warmer or cooler? Response to a reader II”, the numbers that the GISS has given are adjusted.
Which is what former Hadley director Phil Jones said in February 2010 in an interview with the BBC: there has been no “statistically significant” warming since 1995, and since 2002 there may have been some cooling, although he doesn’t consider this cooling “statistically significant.” Of the two options, though, he prefers the “statistically insignificant” warming over the “statistically insignificant” cooling.” In his movie “An Inconvenient Truth”, Al Gore discusses a few main points that are of interest. The first is the topic of the last 14 years being the warmest in recorded history. As we have already discussed in a previous paragraph, that fact is reliant on “adjusted” facts. He also uses the emotional side of the issue by showing some pictures of a few famous places such as Mt. Kilimanjaro 30 years ago and now. The snow levels have indeed dropped considerably. On that same topic he says that if Antarctica was to melt then the sea levels would rise 20 feet. If the sea rose 20 feet it would be a catastrophe, fortunately, the odds of Antarctica melting are extremely slight. The third point he uses is the fact that global warming has caused bigger more dangerous storms. Most of what is talked about in his film is based on speculations or incorrect information.
