Greenhouse Gases and Their Effect On Our Planet

Greenhouse gases, are they as big of a problem as people say? People who know little about greenhouse gases, truly are not aware how its effects on our earth, so hopefully this information will show you how serious this problem actually is.

For 2.5 million years, the earth's climate constantly been changing, from ice age to warmer years, but in the last century our climate's temperature has been rising unusually fast, from about 1.3 to 1.5 degrees Fahrenheit. Scientists believe that it is our own human activity, that's driving the temperature up, and this process is called "global warming".

Dating back to the times when the industrial revolution began, factories, trains, and eventually cars, have burned fossil fuels such as oil and coal, which were and still are, releasing huge amounts of carbon dioxide, and other gases into our earth's atmosphere. These greenhouse gases, or trapped heat near the surface of the earth, are formed by a natural process of the sun, and this is called the "greenhouse effect". The greenhouse effect, begins with the sun and the imagery it radiates to the earth. The Earth and the atmosphere absorb some of this energy, and the rest is radiated back into space. Now with that being said, these naturally occurring gases, in the atmosphere trap some of this energy and reflect it back, thus, warming the earth. Scientists now believe that the greenhouse effect is getting intensified by all the extra greenhouse gases that humans are releasing.

Signs of global warming, include a recent pattern of very warm years. 1998 was one of the warmest years in history, with 2005, a quick runner-up. Furthermore, readings taken from ice core samples, show that greenhouse gases, CO₂, and methane, have hit their highest levels in 420,000 years, and our sea ice is also shrinking. Our sea ice has declined 10% in the last 30 years.

As long as our nations around the globe, consume these energies, and increase their fuel consumption the overall mass of greenhouse gases will continue to rise. Researchers predict that our temperature will increase by 2 - 10 degrees Fahrenheit by the end of the century. What is uncertain is what rising temperatures, will mean for our planet. Some forecast rising sea levels which, of course, would mean floods, along coastal areas around the world. Weather patterns are changing also, making hurricanes more frequent, severe drought is more common in warm areas, and species which are unable to adapt to this change will face a huge drop in numbers, and inevitably, extinction.
