Twenty-first century surface UV radiation changes deduced from CMIP6 models. Part II: effects on UV index and plant growth weighted irradiance.

This paper investigates the evolution of changes in surface ultraviolet (UV) radiation globally, emphasizing the significant impacts of key factors influencing its variability, i.e., total column ozone, aerosols, clouds, and surface reflectivity.

Continuing benefits of the Montreal Protocol and protection of the stratospheric ozone layer for human health and the environment.

The protection of Earth's stratospheric ozone (O) is an ongoing process under the auspices of the universally ratified Montreal Protocol and its Amendments and adjustments. A critical part of this process is the assessment of the environmental issues related to changes in O. The United Nations Environment Programme's Environmental Effects Assessment Panel provides annual scientific evaluations of some of the key issues arising in the recent collective knowledge base.

Complex Regulation of Protocadherin Epigenetics on Aging-Related Brain Health.

Life expectancy continues to increase in the high-income world due to advances in medical care; however, quality of life declines with increasing age due to normal aging processes. Current research suggests that various aspects of aging are genetically modulated and thus may be slowed via genetic modification. Here, we show evidence for epigenetic modulation of the aging process in the brain from over 1800 individuals as part of the Framingham Heart Study.

FIR agreement Indonesia - Singapore: What are the legal implications?

This paper explores the implications of Indonesia's agreement to delegate the Flight Information Region (FIR) of air navigation services to Singapore, specifically in the airspace of the Riau and Natuna islands, as stated in Presidential Regulation Number 109 of 2022. Using the normative juridical method, this study examines the intricate details of the agreement, with a focus on its potential legal consequences for Indonesia's national and international obligations. Although Indonesia retains sovereignty over its territory, this analysis scrutinizes the nuanced provisions of the agreement and their implications, particularly in terms of the technical aspects of air traffic services provided by the Singapore Air Traffic Services Provider above Indonesia's territories, which the agreement does not explicitly delineate the responsibilities or shared consequences in law.

Environmental plastics in the context of UV radiation, climate change, and the Montreal Protocol.

There are close links between solar UV radiation, climate change, and plastic pollution. UV-driven weathering is a key process leading to the degradation of plastics in the environment but also the formation of potentially harmful plastic fragments such as micro- and nanoplastic particles. Estimates of the environmental persistence of plastic pollution, and the formation of fragments, will need to take in account plastic dispersal around the globe, as well as projected UV radiation levels and climate change factors.
