Global Warming

Global Warming is the rising of the Earth’s surface temperature due to chemicals in the
atmosphere. Global Warming has many threats on the climate and even the health of the people
on this planet. Some of these threats include the altering of crop seasons and even effect the way
organisms survive on the planet. The first thing I think I should discuss when talking about
global warming is what causes it to occur. Gases such as carbon dioxide, methane and nitrous
oxide, which are known as greenhouse gases, all build up in the atmosphere of the earth. All
these gases make it so that it becomes harder for the radiation that the sun shines into the
atmosphere to escape. The heat continues to build up and this is what causes the temperatures to
increase. I know this seems like the temperatures increase massively but in the last hundred
years the average temperature of the Earth has gone up between 0.8 and 1.0 degrees
farenheight(1). Also, in the last fifteen years, we have had the ten warmest years in record.(1)
Global warming is not always a negative process though. Without global warming, the
Earth’s temperature would be a lot lower than the 60-degree average. Unfortunately due to there
being many more harmful “greenhouse gases” being placed into the atmosphere, instead of the
temperature staying at a constant, its rising(1). There are many dangers associated with the
Earth’s temperature rising. First of all it causes many of the glaciers that are floating in the
Arctic and Greenland to melt. This in turn causes the sea levels to rise around the world. In the
last hundred years alone the seas around the planet have risen anywhere from four to ten inches.
I know it does not sound like a massive change but being able to raise all the seas in the world a
whole ten inches is a huge problem. Sea levels also continue to rise is because the hotter
temperature cause the ocean water to expand. An example of the sea le...
