The statistics for recent years of weather and climatic cataclysms that happened in Russia are presented. Threats for various sectors of the economy resulting from the above cataclysms are indicated. The need for adaptation measures aimed at preventing and mitigating the consequences of such threats is discussed.

Calcium silicate hydrates (CSH) are widespread in nature and are commonly used in cement production. Their cationic composition consists only of Ca and Si, and the chemical variations of this family result from the variations of Ca/Si ratio, anionic composition, and hydration degree. The structural diversity of this family is related to the variations of Ca polyhedral fragments and Si radicals as well as to their topology and symmetry in the structure. Earlier I presented in “Priroda” the structure of fukalite and closely related calcium silicate hydrates with infinite oxygen radicals. This work is dedicated to the X-ray analysis of another member of the CSH family, afwillite, with isolated SiO4 tetrahedra and other calcium silicate hydrates with finite Si-radicals and their combinations.

The article represents data on tiger records in Bureya Nature Reserve in the north of the Amur River region. In the Reserve, for the first time traces of a tiger were noted in November 2018, and then traces (from one animal) were found in September 2020. In October 2020, for the first time in the Reserve, a tiger was caught by a camera trap located on the right bank of the Levaya Bureya River near the mouth of the Lan River. In November, probably, the same individual was photographed again at the same location. The tiger caught by the camera in October 2020 was again recorded in June 2021. It was an adult female. The valley of the Levaya Bureya River, near the mouth of the Lan River, provides the best habitats for elk and red deer in the Reserve. Information about the tiger population in the vicinity of the Reserve is considered.

One half (1/4 each) of the Nobel Prize was awarded to climatologists Syukuro Manabe and Klaus Hasselmann “for the physical modelling of the Earth’s climate, quantitative variability and reliably predicting global warming”. This is not the first time the Nobel Committee has noted the problem of climate change. However, for the first time, scientists who laid the foundations of modern climatology were awarded directly.

Новую книгу Н.С.Розова бесспорно следует считать новаторской. По богатству содержания ее можно сравнить только с фундаментальной сводкой «Эволюция языка» Уильяма Фитча (W.T.Fitch) [1]. Впрочем, две эти книги резко отличаются по характеру организации материала. У Фитча он строго рассортирован по стандартным традиционным категориям, таким, например, как археология, палеонтология, эволюция анатомических особенностей антропоидов, гоминид и человека (мозг, аппарат вокализации и пр.). В книге Розова основной интерес сосредоточен на выявлении генезиса, взаимосвязей и взаимовлияний различных факторов, значимых в процессе эволюции языка — не только в области трансформаций коммуникативных систем как таковых, но также палеоклиматических, экологических и социальных. Последним уделено особое внимание. Такой подход, ориентированный на синтез сведений, накопленных в разных разделах эволюционной антропологии, предопределил характер изложения — обилие классификаций при систематизации эволюционных явлений самых разных уровней общности. Тому же служит иллюстративный материал, представленный весьма многочисленными блок-схемами.
