Well I am glad you asked me that question, and so here comes the answer as I after much reading understand it.
Global warming is a gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
Global warming can be best understood as the gradual heating of Earth’s surface, oceans and atmosphere. Since the late 1800s scientists have documented the rise in average temperatures worldwide. Earth’s average temperature has risen by 1.4 degrees Fahrenheit (0.8 degrees Celsius) over the past century, according to the Environmental Protection Agency (EPA). Scientists say the temperatures are projected to rise another 2 to 11.5 degrees F (1.133 to 6.42 degrees C) over the next 100 years. Is that a scary thought to more people than me????
Most of the leading scientific organizations in the world acknowledge the existence of global warming as a fact, according to a NASA report. Furthermore, 97 percent of climate scientists agree that the rate of global warming trends the planet is now experiencing is not a natural occurrence, but is primarily the result of human activity. That consensus was made clear in a major climate report released Sept. 27, 2013, by the Intergovernmental Panel on Climate Change (IPCC). In that report, climate scientists indicated they are more certain than ever of the link between human activities,and global warming.
The greenhouse effect:
Global warming begins with the greenhouse effect, which is caused by the interaction between the Earth’s atmosphere and incoming radiation from the sun. The basic physics of the greenhouse effect were figured out more than a hundred years ago by a smart guy using only pencil and paper Svante Arrhenius in 1896 was far ahead of his time.
Solar radiation passes through the atmosphere to the surface of Earth, where it is absorbed and then radiated upward as heat. Gases in Earth’s atmosphere absorb about 90 percent of this heat and radiate it back to the surface, which is warmed to a life-supporting average of 59 F (15 C). This very helpful process is called the greenhouse effect.
Personally I find the topic of global warming/the greenhouse effect, and how it affects us deeply terrifying but interesting at the same time. Once you start reading on the topic you find how little you really know, and how much you truly ought to understand plus read up on when it comes to this topic. The topic is something we hear so much about, and try to discuss without really knowing what we talk about. When we choose to have an opinion on such a large, and well researched topic. We should do our very own research, and read multiple sources at the same time. That way you can make up your own mind, and have as informed opinion as possible. We should be more critical of what the media prints, but that is an entirely other topic 🙂
The topic of global warming, and greenhouse gasses is something I will be writing a whole lot more on in the future!
