Global Warming a Hoax?

There are many people that believe that global warming is just a hoax, and that it is not a serious issue. All of the people that don't believe in global warming all have their different opinions on why they don't believe the issue about global warming. Some say that there is no real evidence supporting global warming, that one record year is not good enough evidence, that glaciers have always grown and receded, that one hundred years of global surface temperatures is not enough time, and that basing global warming on the temperature record is not reliable. There is also some evidence that could show that global warming is just a hoax, but with that evidence you ned to look deeper, and see what actually is happening. Some evidence shows that Antarctic ice is growing, some evidence shows that global warming stopped in 1998, Antarctic sea ice is increasing, the sea level in the Arctic is falling, and glaciers are not melting. These are the many reasons why people think that global warming is just a hoax, but you must see the big picture in order to get the overall view.

Global Warming Causing Bigfoot to Move North?

At a Bigfoot convention, called Bigfoot night, Bigfoot enthusiasts had a discussion on how Bigfoot was moving north due to global warming. They say that a nine-foot tall animal covered in dense fur would want to move north. They were migrating across Yosemite National Park, but due to the hot temperatures, Bigfoot is moving north to Canada.

Greenhouse Gas Effect

Greenhouse gases are chemical compounds that are found on Earth. The sunlight from the sun is re-directed towards space, and captured by the greenhouse gases. These gases are essential to living because they allow the Earth to keep warm. If all of the greenhouse gases were gone the Earth would be very cold, and we would not be able to live. The Earth emits its own greenhouse gases that is just enough to keep the Earth at the right temperature. The emission of greenhouse gases that we emit harm the atmosphere, because if to much greenhouse gases are in the atmosphere, more heat is trapped, and the Earth heats up. Some chemicals are water vapor, carbon dioxide, methane, nitrous oxide, ozone, and CFC's. Carbon dioxide is one of the most abundant gases that are emitted by humans.

Carbon Dioxide levels

Carbon dioxide is one of the major pollutants, that aid to global warming. America is one of the biggest contributors to global warming. America makes up 4% of the world's pollution, and produces 25% of the worlds carbon dioxide pollution. The United States emits more carbon dioxide then China, India, and Japan combined.

What is Global Warming

Global Warming is when carbon dioxide and air pollutants cause a "blanket" in the earth's atmosphere. The heat from the earth and the sun is getting trapped under this thick blanket. This is making the planet to warm up. The Earth is actually getting warmer, over the past 50 years the average global temperature has increased the fastest ever.

Update: the warming trend for the last 50 years is 0.13^oC per decade, nearly twice that for the previous 100 years. The total global average temperature increase from 1850-2005 is now 0.76^oC.

Anomalies are often used, rather than absolute measures, as the nature of the data frequently shows changes in quantities better than absolute. The anomaly is plotted against some reference figure, in this case the 1961 to 1990 average temperature. As shown, global average surface temperatures have been higher than this average for at least 20 years. Also, since 1979, land temperatures have increased about twice as fast as ocean temperatures, 0.25^oC per decade against 0.13^oC per decade respectively (Smith, 2005). Update: 11 of the last 12 years (1995-2006) were among the warmest on the surface temperature record.
