Atmospheric rivers cause warm winters and extreme heat events.
Nature

Yale University, Department of Earth and Planetary Sciences, New Haven, CT, USA.
Atmospheric rivers (ARs) are narrow regions of intense water vapour transport in the Earth's atmosphere. These transient phenomena carry water from the subtropics to the mid-latitudes and polar regions, making up the majority of polewards moisture transport and exerting control on the precipitation and water resources in many regions. In addition to transporting moisture, ARs also transport heat, but the impact of this transport on global near-surface air temperatures has not yet been characterized.

In the context of global warming and rapid urbanization, the frequency of simultaneous occurrence of extreme high temperature, ozone pollution, and particulate matter pollution has increased. However, independent and composite characterization of PM, ozone, and extreme heat pollution events has not been systematically analyzed so far. This study combines meteorological and pollutant data with the GTWR model in an attempt to reveal the patterns of independent heat days (IHD), compound PM-ozone pollution (CPOP), and composite heat-PM-ozone pollution (CHPOP).

Heatwaves have substantial but poorly quantified impacts on surface ozone photochemical regimes. As heatwaves of increasing severity occur, communities face more serious exposure to ozone, necessitating a more comprehensive understanding of the impact of heatwaves on the nonlinear response of ozone to its precursors for guiding policies in emission reductions. Here we estimate the spatiotemporal evolution of global ozone chemistry based on machine learning and in situ observations and show that emission changes and heatwaves alter ozone photochemical regimes, leading to diverse ozone changes across regions.

Department of Culture and Media Studies, Umeå University, 901 87 Umeå, Sweden. Electronic address:
In recent years, a relatively large number of articles in the Swedish media have reported on the problems that afflict nursing homes due to prolonged and climate-related heatwaves during the summer months. Older residents are badly affected by the heat, especially as many nursing homes in Sweden lack air conditioning. This paper aims to explore how nursing homes are depicted in the Swedish press in relation to climate-related heatwaves, professional care, and risk management.

J Clin Endocrinol Metab
November 2024
Department of Endocrinology, Austin Health, Heidelberg, Australia.
Objectives: To determine the relationship between ambient air temperature and the incidence of hyponatraemia in a heat-prone region.
Design And Setting: We conducted a retrospective study that correlated serum sodium concentrations documented at The Austin Hospital in Melbourne over ten years from January 2014 to December 2023, with publicly available temperature data from the Australian Bureau of Meteorology.
Main Outcome Measures: Serum sodium concentrations and incidence of hyponatraemia admissions when correlated to temperature, and following heatwave events, defined as temperature above 30°C over five consecutive days.
