Venus as possible future of the Earth

... years ago. At this time, the Earth saw the formation of the modern oceans, continents, and biosphere (Dobretsov, 2010, 2014). Over the past 200 million years, the Earth’s surface has come to look as it does today while the Venusian atmosphere and volcanism have been functioning at the same relatively stable level. Thus, the evolution of the Solar System as a whole is a most complex phenomenon, whereby the termination of activity on one planet is accompanied by the beginning or an increase ...

Major Supereruptions in the Earth’s History Were Caused by Deep Water Migration

Siberian scientists, in collaboration with colleagues from France and Saudi Arabia, used a comprehensive geophysical study of the deep structure beneath the Toba Caldera on Sumatra to simulate the processes leading to the recurrent supereruptions. The results of this study have been published in the prestigious journal Nature Communications The supereruption is an explosive eruption ejecting, in a single event, over 1000 cubic kilometers of material in the dense rock equivalent. Over the past...

Climate in Time and Space

... relative movement of the continents results in changes in the configuration of oceanic currents, even though it takes millions of years. One of the most significant factors in climate variation is associated with the changes in the nature and intensity of volcanism with the periodicity of up to tens of thousands of years. They result in enormous amounts of greenhouse gases (carbonic acid, methane, etc.) emitting into the atmosphere which exceed the waste from industrial enterprises and thermal power plants ...
