Serbian mathematician Milankovic has developed the theory about the cause of the change of the ice sheet of the earth. He believes that small changes in the orbit of the Earth may lead to extreme changes in the climate. During about 41,000 years, the axis of rotation varied from 22 degrees to 24.5 degrees, melting the glacial ice caps in the Northern Hemisphere. Climate warming and cooling are directly affected by glaciers. Recent technology has led the scientists to see that glacial changes are related to changes in the Earth's orbit over the past millions of years.
Global warming is a major environmental and economic challenge that we face in the 21st century. Global warming is often referred to as greenhouse effect. Global warming affects the entire ecosystem and the climate as a whole and therefore may affect people's lifestyles. We will not see the main impact of global warming during our lifetime; however, it remains a big problem. As we all know, the rapid temperature rise in the last century was the result of the industrial revolution. During the Industrial Revolution, when new machines were used, the amount of atmospheric carbon dioxide increased significantly. And that is one of the main causes of the greenhouse effect. This is the main reason why scientists think that temperature rise is a human influence rather than climate change.
Global warming is due to the effects of greenhouse gases and the temperature rise of the earth's surface. The main causes of global warming are the greenhouse effect, the fossil fuel of automobiles, and global emissions. Global warming affects our environment including sea level rise and changes in rainfall pattern. The measures we can take are reducing emissions and reducing greenhouse gas emissions. In this article we will focus on what the global warming brings to our environment. The greenhouse effect is one of the causes of global warming. The greenhouse effect is global warming that occurs when gas in the atmosphere of the earth is captured by heat. An example of a greenhouse effect is that sunlight passes through a transparent window. This happens because the gas absorbs the ultraviolet radiation that radiates to the universe. When irradiated, carbon dioxide absorbs this heat and air becomes hot as more carbon dioxide in the atmosphere is.
