spamsinkКстати об озоновых дырах: Как известно, наличие озонового слоя, защищающего поверхность Земли от ультрафиолетового излучения, в атмосфере Земли обеспечивается ее магнитным полем, которое защищает этот слой от уничтожения солнечным ветром:
The magnetosphere is the region above the ionosphere and extends several tens of thousands of kilometers into space, protecting the Earth from the charged particles of the solar wind and cosmic rays that would otherwise strip away the upper atmosphere, including the ozone layer that protects the Earth from harmful ultraviolet radiation.
Это с одной стороны. С другой стороны (ibid),
At present, the overall geomagnetic field is becoming weaker; the present strong deterioration corresponds to a 10–15% decline over the last 150 years and has accelerated in the past several years; geomagnetic intensity has declined almost continuously from a maximum 35% above the modern value achieved approximately 2,000 years ago.
Вот и интересно, в какой степени в этих пресловутых озоновых дырах виноваты фреоны, а в какой - ослабление магнитного поля.
