The scientific reason global warming is explained by a universal phenomenon called greenhouse effect. Most people know about this scientific explanation, but do not know the invention or the inventor.
Charles David Keeling is the scientist, who explained on the basis of the scientific environment of global warming in the first place. In 1958, he created an instrument called a legacy meter can measure greenhouse gases gnarliest of all carbon dioxide (CO2). So for a year, took daily measurements of atmospheric carbon dioxide at Mauna Loa, Hawaii, where he created his caliber. After we did a table reading. Found the level of CO2 decreased in summer and winter, has increased. This is because in summer the plants are grown and full of leaves. Through a series of reaction called photo and dark reactions of CO2 is transformed into carbohydrates, amino acids and lipids within chloroplasts in leaves. This process is called photosynthesis. So if there is a lot of leaves, which can absorb more CO2, then CO2 levels decreased. This is the reason to call the plants as a sink for CO2.
In winter, the leaves have fallen and the link does not go so well. So the CO2 levels have risen, because a smaller amount of CO2 is consumed. He called this an annual cycle of atmospheric carbon dioxide
Keeling was fascinated by this discovery and continued his research for three decades and has taken steps daily. After tracing all his reading, was stunned by what he found. He noted that the high concentration of CO2 in the winter increases each year and the low concentration of CO2 in the summer also is increasing every year. After analyzing all the information, it was found that the concentration of CO2 in the atmosphere is increasing and that the world knows. Table Keeling fact reading is now known as the "Keeling curve.
In 2004, the British Antarctic survey team is known as "Down" is a search based on the ice sheet of Antarctica. They pierced the ice about 3 miles and took ice core samples. The oldest layers in the samples were approximately 650,000 years. Then analyzes the air bubbles had been trapped in frozen ice. After these tests found that the concentration of CO2 has increased by 27% over the 650,000 years. They also found the slow increase of the concentration of CO2 over the last 650,000 years, when modern man took only 17 years because of the same kind of growth. Again, the connection between global warming and CO2 has been tested.
The latest estimates show that CO2 gas is the main greenhouse gases (GHG) emissions and their impact on global warming is about 85%. The main source of this CO2 is the burning of fossil fuels. Every day 100 million tons of CO2 released into the atmosphere by human activities. So how could such a world will make a statement about carbon neutrality? Thanks to the agreements so the authorities should be more practical. Otherwise the world would have no disaster, but more carbon.
