Global Warming Due To Contrails

GLOBAL WARMING DUE TO CONTRAILS

 You may have seen an airplane flying across the sky, leaving a white trail behind it. These lines are called "contrails". Actually, when any type of fuel is burned in an engine, two things are produced in the form of impurities. One is carbon dioxide and the other is water vapor. The engine of the ship also produces this water vapor and carbon dioxide which the ship emits out of its engine. At the height at which the plane flies, the atmosphere is quite cold, due to this cold, these water vapors freeze in a way (condense) and due to their freezing, those white lines are seen behind the plane.

These lines may look good, but they cause global warming. What is global warming? Heat actually comes from the Sun to our Earth in the form of waves, which heat the Earth, but some of these waves hit the Earth and radiate back into space. But due to some gases and air pollution, a layer of polluted gases is formed in the upper atmosphere of the earth, which does not allow the waves that hit the earth to return, and thus these waves are trapped on the earth and the temperature of the earth decreases. Grows. This process is called global warming. This rise in temperature leads to various problems like melting of glaciers, floods and weather disasters etc.

The frozen water vapor in these lines also becomes part of this layer causing global warming and thus is also a cause of global warming. Rather, they are nearly four times more dangerous than carbon dioxide in terms of global warming. It is currently a major source of aviation pollution. Various methods have been adopted to reduce carbon dioxide emissions from ships. But no successful practical method for "contralls" of these vapors has emerged.

But then the woman "aeronautical engineer" Dr. Sara Qureshi of Pakistan created an engine that would not only prevent these water vapors from going out and form contrails, but would also keep it inside, but also make these stored water vapors rain. Can also be used for. That is, two kills with one arrow. I came to know about Dr. Sara Qureshi's feat a month ago (seeing a question about her in an exam). Credit for Sara Qureshi's success goes to her father, who is a physicist himself, and the father-daughter duo (pictured) have also created a company to bring their inventions to the world.
