Global warming

Different eras bring different fears and related myths to humanity. The fantasies and imaginations of ordinary people simply did not keep pace with the increase in the number of inventions and innovations in everyday life.

The end of the 20th century and the beginning of the 21st century were marked by new fears - of the financial crisis, nuclear war, environmental problems. One of the most discussed topics was the problem of global warming, which threatens humanity with big troubles. Let's reveal some of the myths about this phenomenon.

Global warming does not exist at all, this is the invention of scientists. Unfortunately, the facts stubbornly insist that the average annual temperature of the atmosphere began to rise steadily with the onset of rapid industrial growth. So far, this is all - only 0.7 degrees, but further forecasts really make one think - in the 21st century the average temperature may rise to 6 degrees, and in Europe - generally up to 10 degrees.

This phenomenon is a natural process. Temperature rise graphs are directly related to industry growth graphs. Such human activity leads to the emission of greenhouse gases, which cause heating of the atmosphere. Therefore, for this problem, the influence of natural causes is incomparable with the anthropogenic factor.

Carbon dioxide emissions are too small to affect global warming. On the contrary, it is these emissions that are the main problem with which humanity can and must fight. In 1980, the leading countries emitted more than 100 million tons of CO2 into the atmosphere. And if now the advanced countries are reducing these volumes, the developing ones, on the contrary, are increasing. It is no coincidence that over 160 countries signed the Kyoto Treaty in 1997, which obliged advanced countries to reduce carbon dioxide emissions into the atmosphere. The graphs of the temperature of the atmosphere and the concentration of CO2 in it coincide.

Do not be afraid of warming, as its consequences will enter life gradually. Climate change is leading to an increase in the number of natural disasters such as hurricanes, droughts and storms. Moreover, history knows examples when the climate can change dramatically, in just a few years.

Global warming will lead to a worldwide flood. The average rise in sea level over a century was 0.5 meters. This figure has now doubled. Assuming that all the glaciers will melt overnight, we get a 10-meter rise in ocean level on the planet. But the average land height above sea level is more than 800 meters, so we are not threatened with flooding.

It is global warming that is the only reason for sudden changes in weather and natural disasters. Nature is a rather complex mechanism that has not yet been fully explored. There are a great many natural processes in it that lead to warming, cooling, typhoons and droughts. Something is affected by ocean currents, something by cyclones, changes in the Earth's magnetic field also play a role. It is enough to study history to find out that natural disasters and climatic transformations of mankind regularly experienced, even in those times when there was no warming at all.

Global warming will lead to a rapid rise in temperature and death of humanity. As mentioned above, the rise in average temperature in the worst case will rise 0.7 to 4.6 degrees per century, which, of course, poses a certain danger to humanity, but is not critical. More restrained forecasts speak of an increase in temperature generally only up to 2 degrees. In addition, according to experts' forecasts, climatic changes may affect the functioning of the Gulf Stream, which heats Europe, which may cause it to get a little colder on this continent.

Global warming and warm weather will only be beneficial. Of course, in some areas the winter will become milder and the summer hotter, but the cost of negative consequences will be disproportionately higher. Climate change brings devastating natural disasters, epidemics of unprecedented diseases, deaths due to unbearable summer heat. For example, in the summer of 2003 alone, an unprecedented sultry summer killed more than 20,000 people in Europe. It is believed that warming will benefit agriculture, but as the yield of some crops rises, weeds and pests should also increase. In addition, climatic shifts will negatively affect the life of plants, which may no longer be able to grow in new conditions.

Governments are solving this problem. The Kyoto Treaty only limits harmful emissions, but not all countries have signed it, including with the United States, which is the largest "supplier" of carbon dioxide to the atmosphere. It is impossible to effectively combat emissions without economic consequences, which, of course, does not suit anyone. Therefore, while the main struggle is reduced to the expression of intentions, meetings, protocols and nothing more.

This is not as serious a problem as, say, national security. The fact is that global warming will affect each of us, no one will be left on the sidelines. That is why this problem is called global. Therefore, do not underestimate her.

All causes of global warming are known. There is a common misconception that man and his industrial activities are to blame for everything. If you stop it, you can prevent a catastrophe. In fact, this problem is quite new, so it is impossible to say with certainty about the reasons for its occurrence. There are several versions. The most common version says that this process is quite natural, as it is a reflection of what occurs in the Sun-Earth-Space system. The climate changes periodically depending on the parameters of the orbit, volcanic activity, the rhythms of the Sun. Therefore, there are a lot of deep factors and this problem cannot be unequivocally explained, although no one denies the influence of the human factor.

Modern technologies are helping to combat warming. There are many large-scale plans that will help us deal with this problem, but they are rather strategic and are still in the realm of fantasy, and their implementation will require significant funds, comparable to the budget of a developed country. Therefore, so far no one is in a hurry to implement them.

This process is irreversible and nothing can be changed. In fact, each of us, simply observing everyday rationalism, is already making a small contribution to the fight against this danger. We may not notice our contribution, but it will have a beneficial effect on the future of our children and grandchildren.
