It is established that the water of the soda lakes is more enriched with oxygen-18, but in smaller - with deuterium. It is shown that the enrichment of the waters of salt lakes with heavy isotopes is due not only to the evaporation process, but to the interaction of water with the rock. The participation of the reactions of hydrolysis of alumosilicates in the fractionation of oxygen is confirmed by the direct dependence of the magnitude of the oxygen shift on pH, the value of which depends on the degree of such interaction.","PeriodicalId":24047,"journal":{"name":"Доклады Академии наук","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88051940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accounting for changes in climatic conditions can strongly influence the indicators of the impact of various greenhouse gas emissions on the climate system, especially at large time horizons. Moreover, depending on the planning horizon, the role of the natural fluxes of greenhouse gases into the atmosphere from terrestrial ecosystems may change. Currently, terrestrial ecosystems in the Russian regions affect global temperature in both directions: absorbing CO2 from the atmosphere contributes to slowing its growth, and emitting CH4 into the atmosphere accelerates warming. The net effect of the natural fluxes of these greenhouse gases from the Russian regions in modern conditions helps to slow down warming. This net effect is increasing in the first half of the 21st century, and after reaching a maximum (depending on the anthropogenic emission scenario) decreases by the end of the century under all the considered anthropogenic impact scenarios due to an increase in natural CH4 emissions and a decrease in CO2 absorption by terrestrial ecosystems.","PeriodicalId":24047,"journal":{"name":"Доклады Академии наук","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75356292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this case, the short-period stage (period ~ 0.5-0.8 min) and long-period stage (period ~ 5-20 min) of increased geomagnetic variations are clearly distinguished. The maximum amplitude of induced geomagnetic variations is 1.5-2 nT and 2- 4 nT, respectively, for short-period and long-period variations.
