GLOBAL WARMING AND CLIMATE CHANGE
July 21, 2014
Global warming is still a debate between us. Most people do not believe that our world is warming up, they believe the climate is in a cycle, and that humans do not contribute to the warming of our climate. Research supports the fact that Global warming is a huge factor in climate change and that human activities are increasing the warming of our world. When we look around the world today, we see that our seasons come in later times than usual, glaciers are melting rapidly than it did thirty years ago, animals are migrating farther than they usually do, to find food and water because it is too hot and the waters are drying up and food source is scarce. Our climate is changing, and this is as a result of global warming. The earlier people are educated and aware of this, and take caution to help preserve and save our environment; the better it is for our climate, if not I fear the future impact.
The Concept of What Global Warming Means Global warming is the continual rise in the average temperature of the earth’s climate system. In Layman’s terms, global warming, just like the name implies is the heating up or the warming of the earth. Global warming was discovered since the 1800’s, the scientific study of the causes of global warming has become broad. Since the early 20th century, the global air and sea surface temperature has increased about 0.8 °C (1.4 °F).” (Source: National Geographic). Global warming is primarily a result of too much carbon dioxide (CO2) gases and other greenhouse gases in the atmosphere. Green house gases are gases, which act as some sort of layer, that trap heat in the atmosphere. The green house gases have different heat-trapping abilities. Examples of these gases are methane, carbon dioxide, water vapor, nitrous oxide, ozone, and chlorofluorocarbon. One of the first things scientists learned about green house gases is that, they all have different heat trapping abilities. Some of them can even trap more heat than CO2. One molecule of methane produces more than 20 times the warming of a molecule of CO2. Nitrous oxide is 300 times more powerful than CO2. Other gases, such as chlorofluorocarbons, have heat-trapping potential thousands of times greater than CO2. But because their concentrations are much lower than CO2, none of these gases adds as much warmth to the atmosphere as CO2 does.

Humans emit them in a multiple ways, most come from the combustion of fossil fuels, coals, the release if CO2 gas from factories and so on… But none of these gases add as much warmth to the atmosphere as CO2 does, due to its concentration.

Effects Of Global Warming Signs are appearing all over the world, of the impacts of global warming: There are a lot of impacts the climate change brings about to our environments. In wildlife, plants, ecosystem, agriculture, health, forest, coastal areas, energy, recreation. To elaborate: Rapid melting of ice: It is no shock that our climate is rapidly changing due to Global warming. Ice is melting rapidly, especially in the Northern American continents. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice. (Source: National Geographic) Wildlife: Due to severe changes in our climate, animals have to leave their habitats to migrate father away to find food, water and even mate. Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas. For those who cannot adapt,...
