Carbon dioxide emissions from fossil fuels rose again in 2023, reaching record levels, according to estimates from an international team of scientists.

Every year, more than one million deaths globally occur because of exposure to short-term (hours to days) fine particulate matter (PM2.5) in air pollution, according to a new report, with Eastern Asia reporting more than 50 per cent of deaths attributable to short-term PM2.5 globally.

Looking for solutions to manage the global crisis of microplastics pollution, particularly in marine environments, will be the focus of the 1st Nano and Microplastics Australian Conference at Flinders University (7-8 March 2024).

UFZ analysis shows a mix of chemicals that endanger invertebrate organisms in particular.

Getting climate models to mimic real-time observations when it comes to warming is critical – small discrepancies can lead to misunderstandings about the rate of global warming as the climate changes. 

A novel approach using laser-made nanomaterials created from nonprecious metals could lay the foundation for globally scalable remediation techniques.

Scientists led by an Oregon State University chemistry researcher are closing in on a new tool for tackling the global problem of weedkiller-tainted groundwater.

The new analysis, led by scientists at British Antarctic Survey (BAS), suggests that the decline was more gradual than some previously believed and that large-scale land use changes as Europeans colonised the Americas are likely responsible.

The cost of removing large quantities of CO2 from the air will fall in the medium term, but not as much as previously hoped. 

A team of researchers from the University of Massachusetts Amherst that specializes in accounting for the carbon dioxide release by streams, rivers and lakes recently demonstrated that the chemical process known as “carbonate buffering” can account for the majority of emissions in highly alkaline waters.
