This study investigates the impact of combined drought and extreme heatwave events on air quality in South Africa during October 2022 (study period). An analysis of meteorological data revealed a sharp increase in surface air temperature and a significant decrease in precipitation, resulting in an extreme heatwave and drought period. The Standardized Precipitation Evaporation Index (SPEI) for October 2022 showed an extreme dro...

Central Asia (CA) is among the world's most vulnerable regions to climate change. Increasing anthropogenic greenhouse gas concentrations (GHGs) are the primary forcing of the current and future climate system for the time scale of a century. By analysing observation datasets, we show that a warming of 1.2°C led to a decrease of 20% in snow‐depth CA during the last 70 years, especially over the mountains. In recent decades, lon...

We study the impact of recent global warming on extreme climatic events in Central Asia (CA) for 1901-2019 by comparing the composite representation of the observational climate with a hypothetical counterfactual one that does not include the long-term global warming trend. The counterfactual climate data are produced based on a simple detrending approach, using the global mean temperature (GMT) as the independent variable and...

Background Previous studies suggest that chemical constituents present in Pinus eldarica Medw ( P. eldarica ) nut possess antioxidant properties that may positively influence lipid profile. The present study was conducted to evaluate the efficacy of P. eldarica nut on the experimental atherosclerosis development in hypercholesterolemic rabbits. Methods Forty male 6 months old white New Zealand rabbits (1.8–2 kg) were randomly...
