What is global cooling?

Global cooling is the first time that in the age of 70 is Russian scientists, which states that the global annual temperature is constantly falling. The idea of ​​global cooling was created in the 70 and 80s. The modern frightening Ice Age, but popular culture was largely ignored after global warming. Global cooling may be caused by human pollution, orbital forced or global warming. Aerosol particles, such as smog, are imprisoned in the atmosphere and block some sun rays, reducing the temperature on the ground. However, scientists believe that this effect is generally minimal and is not the main contributor to global cooling, although it is still a problem. Orbital forced is a completely natural phenomenon that occurs, because the Earth fluctuates slightly on its axis when it spins. Thje fluctuations marginally change the orientation of the Earth and the shape of its orbit over time, which in turn changes the amount of sunlight that the ground reaches. Orbital urge is theorized to cause a fingertipsthe oze icy ages.

In addition, global warming can also cause global cooling. When greenhouse gases are captured in the atmosphere, they raise the temperature and melting of the ice cap, it will plunge large amounts of cold water into the ocean, reducing the temperature and causing the climate shift. However, this concept is only theory and later testing has determined that it is unlikely to have drastic consequences in a short time.

Initial research in 70 and up to 80. Although the initial reports in 1972 claimed that the next Ice Age was approximately 20,000 -year, the proposal that human intervention could accelerate the process was worried that the world's population could move the approaching ice age enough to be immediate concern. However, these reports were exaggerated and now with more accurate data on samples and climate change believe that even at theSahu to man is another Ice Age still tens of thousands of years.

In the end, global cooling is still a debate subject, even if it does not receive as much publicity as global warming. However, this is often used in an effort to discount the validity of global warming. Despite the debates and scientific disagreements, one thing remains the same. World temperatures fluctuate. Through the recorded history and probably previously there was a period when temperatures are constantly rising and the period when they were constantly falling.
