The Importance Of Climate Change

Global average Earth 's climate is defined by energy which coming from the sun, the properties of the Earth and its atmosphere such as the ability of reflection, absorption and emission of energy in the atmosphere and on the surface. Although changes in received solar energy, for example caused by fluctuations in the orbit of the Earth 's rotation around the sun, are inevitable, the energy balance of the Earth also affect the properties of the atmosphere and the earth 's surface. We cant know is this changes good or bad, but we can say for sure - people must prepare themselves to climate change. In the atmosphere and in the Earth 's surface there are changes that change global energy balance of the Earth and therefore can lead to climate change.…show more content…
Sun "feeds" the Earth 's climate, radiating energy at very short wavelengths in the visible and invisible, ultraviolet, spectral region. About a third of the solar energy reaching the upper atmosphere of the Earth directly reflected back into space. The other two-thirds absorbing surface and, to a lesser extent, the atmosphere. To balance the energy is absorbed, the Earth must emit an average back into space the same amount of energy. Because the Earth is much colder from the Sun, it radiates energy at much longer wavelengths, primarily in the infrared spectrum. Much of this thermal radiation emitted by land and ocean is absorbed by the atmosphere, including clouds, and radiated back to Earth. This phenomenon is called the greenhouse…show more content…
But rainfall is not spread evenly Earth. In regions that also happens to date are sufficient rainfall, their loss will be more intense. In regions with insufficient moisture more frequent dry periods. Secondly, Modern glaciation of the Earth can be considered one of the most sensitive indicators of global changes that are taking place today. Satellite data show that since 1960, there was a decrease in the area of snow cover around 10%. Since 1950 in the Northern Hemisphere sea ice area decreased by almost 10-15%, and the thickness decreased by 40%. Accelerated melting of glaciers creates a number of direct threats to human development. For very populated mountain and foothill areas special danger of avalanches, flooding or, conversely, lower water levels in rivers, and as a result - reduction of freshwater. Melting glaciers will lead to rising of sea level, in this case, appears the most vulnerable coastal areas and small islands. In addition, more frequent high tides. Finally, climate change will have affect on human health. It will increase risks of different disease to human health, especially the less affluent sections of the population. Thus, reduction of food will inevitably lead to malnutrition and hunger. How we can see climate change will lead to different problems. 
However, we cant stop climate change, but we can slow down this process. Already a lot of scientist working on climate change problem. Each of
