This section contains some works of our colleague V.L. Syvorotkin. He is the author of a concept which explains a wide range of simultaneous disasters that periodically violate the evolutionary stages of the planet. Intensification of deep degassing causes volcanic outbreaks and induces seismic activity. Emissions of the reducing gases to the bottom waters lead to massive loss of aerobic biota. When hydrogen rises to the stratosphere it causes ozone layer destruction. Ozone holes let through additional thermal energy causing weather and climate anomalies, and let through UV radiation which depresses biota.
