<p>The human development of our planet has a variety of negative impacts on the composition of its atmosphere at every scale – locally, regionally, and even globally. One of these dramatic changes has been the increase in the mass concentrations of sub-micrometer particles by one to sometimes two orders of magnitude over populated areas in the Northern Hemisphere. These atmospheric aerosols can cause serious health problems, reduce visibility, contribute to acidic deposition and material damage, but are also cooling the planet by reflecting sunlight back to space. Atmospheric chemistry occurs within a fabric of complicated atmospheric dynamics and physics. This interplay often results in nonlinear and often counterintuitive changes of the system when anthropogenic emissions change. A major goal of our research has been to gain a predictive understanding of the physical and chemical processes that govern the dynamics, size, and chemical composition of atmospheric aerosols.</p><p>To illustrate the advances in the experimental techniques and theoretical tools in atmospheric aerosol science, we will go back to the beginning of the 21<sup>st</sup> century and we will revisit the design a particulate matter control strategy for the Eastern US based on the data, knowledge, and tools available at that time. We will then look at the effects of the parts of this control strategy that have been materialized and their effects on public health using the current understanding. Finally, we will look forward in ways of further improving air quality in the US and Europe.</p>

COVID-19 had a huge mortality impact in the US in 2020 and accounted for the majority of the 1.5-year reduction in 2020 life expectancy at birth. There were also substantial racial/ethnic disparities in the mortality impact of COVID-19 in 2020, with the Black and Latino populations experiencing reductions in life expectancy at birth over twice the reduction experienced by the White population. Despite continued vulnerability of the Black and Latino populations, the hope was that widespread distribution of effective vaccines would mitigate the overall impact and reduce racial/ethnic disparities in 2021. In this study, we use cause-deleted life table methods to estimate the impact of COVID-19 mortality on 2021 US period life expectancy. Our partial-year estimates, based on provisional COVID-19 deaths for January-early October 2021 suggest that racial/ethnic disparities have persisted and that life expectancy at birth in 2021 has already declined by 1.2 years from pre-pandemic levels. Our projected full-year estimates, based on projections of COVID-19 deaths through the end of 2021 from the Institute for Health Metrics and Evaluation, suggest a 1.8-year reduction in US life expectancy at birth from pre-pandemic levels, a steeper decline than the estimates produced for 2020. The reductions in life expectancy at birth estimated for the Black and Latino populations are 1.6-2.4 times the impact for the White population.

The article examines the features of the US foreign policy towards the Central Asian states in the post-bipolar period. The imperatives and constants, as well as the transformation of Washington’s Central Asian policy, have been characterized. It is shown that five Central Asian states have been in the focus of American foreign policy over the past thirty years. In the process of shaping the US foreign policy in Central Asia, the presence of significant reserves of energy and mineral resources in the region was of great importance. Therefore, rivalry for Caspian energy resources and their transportation routes came to the fore. In addition to diversifying transport and logistics flows and supporting American companies, the US energy policy in Central Asia was aimed at preventing the restoration of Russia’s economic and political influence, as well as countering the penetration of China, which is interested in economic cooperation with the countries of the region. During the period under review, the following transformation of mechanisms and means of Washington’s policy in the Central Asian direction was observed: the policy of “exporting democracy”; attempts to “nurture” the pro-American elite; striving to divide states into separate groups with permanent “appointment” of leaders; involvement in a unified military system to combat terrorism; impact on the consciousness of the population in order to destabilize geopolitical rivals; building cooperation on a pragmatic basis due to internal difficulties and external constraints. Central Asian states sympathized with the American course because of their interest in technology and investment. At the same time, these states in every possible way distanced themselves from the impulses of “democratization” from Washington. Kazakhstan was a permanent regional ally of the United States, to which Uzbekistan was striving to join. The second echelon in relations with the American side was occupied by Kyrgyzstan, Tajikistan and Turkmenistan. A feature of the positions of the Central Asian countries is the maximum benefit from cooperation with Washington while building good-neighborly relations with Russia and China, which is in dissonance with the regional imperatives of the United States. In the future, the American strategy in Central Asia will presumably proceed from the expediency of attracting regional allies and stimulating contradictions in order to contain geopolitical rivals in the region.
