climatic changes
The mass extinction of life in the sea and on land 251 million years ago, at the Permian-Triassic boundary, was undoubtedly the largest mass extinction of all time. Sedimentological and geochemical evidence shows that global temperatures rose, that there was extensive oceanic anoxia, and that there was massive erosion of sediment, especially soils, from the land. These phenomena might have been a consequence of the massive eruptions of the Siberian Traps, which produced carbon dioxide, and greenhouse gas, as well as acid rain, which killed plants and led to stripping of soils.
This article considers the questions of influence of the planetary highrise frontal zones (PVFS) on the climatic regime of the Northern hemisphere. Shows the dynamics of the areas PVFS relatively natural climatic periods state the earth’s climate system. The connection of the speakers areas PVFS with the wind regime change in the hemisphere
In the present article influence of a planetary high-rise frontal zone on variability of global climate is considered. It is revealed the high-rise frontal zone loudspeaker during various natural climatic periods of a condition of the Earth’s climate system and their statistical importance is estimated
