The Earth’s climate system (ECS) is considered as a linear system whose input is a change in the solar constant ΔI( t) and the output is an anomaly of the globally averaged surface temperature ΔT( t). The system input can be affected by other factors, and at the output their own temperature fluctuations and a random noise manifest themselves. All these factors are assumed to be independent of ΔI( t). The spectral analysis of monthly mean values of ΔI( t) and ΔT( t) shows the existence of statistically significant coherence. The amplitude-frequency response A( f) of the ECS is different from zero up to the Nyquist’s frequency 0.5 month−1. The results areconsistent with the previously obtained estimate of the equivalent time constant of the ESC 1.31 ± 0.03 month.

An assemblage of chondrichthyans is described from the new locality near Serafimovich town (the western part of Volgograd region). More than 2500 fossils were collected from the basal gravel-pebble bed and phosphorite-bearing layer from the lower part of the Buzinovka formation (upper Paleocene). There are reworked Cretaceous and Paleocene chondrichthyans (6 species) and synchronous 21 species of sharks and 2 species of chimaeroids. The presence of synchronous Gluekmanotodus heinzelini, Odontaspis winkleri, Paraorthacodus eocaenus, Xampylodon loozi allows correlating the described lower part of the Buzinovka formation with NP8 – NP9 nannoplankton zones or Alisocysta margarita – Axiodinium augustum dinocyst zones (Thanetian – basal Ypresian).

This article describes the skeletal fragments of new species of ichthyosaurus Nannopterygius mikhailovi sp. nov. and Nannopterygius yakimenkae sp. nov. from the Upper Volga sublayer of the Upper Jurassic of the West Kazakhstan region of the Republic of Kazakhstan (Shchuchkino section). The species are assigned to the genus Nannopterygius. As studies show fragments of skeletons of representatives of the genus Nannopterygius are often found in Late Jurassic sediments at the location of the village of Shchuchkino in the Krasnovsky rural district of the Bayterek district of theWest Kazakhstanregion. Theselection of newspecies is based on thestructure of the forelimbwith awider diaphysis and a large base of the first finger, the two-facet structure of the femurs which make up 2/3 of the forelimb and the peculiar structure of the main occipital bone and the main sphenoid bone, reinforced by outgrowths along the lateral edges, an enlarged area of the humerus indicating an increase in the area of the forelimbs, the interclavicle having a triangular distal shield.

The analysis of changes in alcohol consumption by the population of Russia for the period from January 2019 to December 2020 in the context of the development of the COVID-19 pandemic was made. The main psychological and social reasons for the increase in the amount and frequency of alcohol consumption during this period are considered, and a discrepancy between the annual dynamics of alcoholic beverages sales and the development of the epidemic is revealed. It is shown that during the coronavirus epidemic sales of strong alcoholic beverages – vodka and liquor products with an alcohol content of more than 25% – are increased. Groups of regions with positive and negative dynamics of alcohol sales during the pandemic were identified.

The results of rock-magnetic and paleomagnetic studies of two sections of the Lower Syzran subformation (Paleocene) of the Saratov Right Bank – the Syrt Mountain (Nizhnyaya Bannovka village) and Lysaya Gora (Saratov city) are presented. For the first time the possibility of obtaining paleomagnetic data on the Paleocene of the Volga region and their use for magnetostratigraphic purposes despite the partial remagnetization of rocks has been established. The prospects of using rock-magnetic characteristics of deposits for detailed correlations of sections and sedimentological reconstructions are demonstrated.

A comparison of average daily values time series of the axial component of the global wind angular moment and galactic cosmic ray (GCR) flux was made. Using the superposed epoch method it is shown that the Forbush decreases of the GCR flux are accompanied by an increase in the average angular velocity of atmosphericcirculation and, accordingly, by an increase in the zonal transfer.

The morphological diversity of diosculumic sponges, known as Paracraticularia cylindrical, results from the fact that many fossils assigned to this species prove to be fragments of the apical segments of internodes (branches) from major colonies that are rarely encountered as totally preserved fossils. The structures of the branch apical segments and the oscula outlines reflect various manifestations of hexactinellida synchronous division conductive to morphological diversity of the descendants, the succeeding complicatedly structured colonial sponges. Some morphs (parataxa) are considered to belong to the species which are mostly fragments of the apical segments from the braches of the Paracraticularia primary colonies.
