UK peatland fires are supercharging carbon emissions as climate change causes hotter, drier summers
2025-02-21
A new study led by the University of Cambridge has revealed that as our springs and summers get hotter and drier, the UK wildfire season is being stretched and intensified. More fires, taking hold over more months of the year, are causing more carbon to be released into the atmosphere as carbon dioxide.
Fires on peatlands, which are carbon-rich, can almost double global fire-driven carbon emissions. Researchers found that despite accounting for only a quarter of the total UK land area that burns each year, dwarfed by moor and heathland, peatland fires have caused up to 90% of annual UK fire-driven carbon emissions since 2001 – with emissions ...

A new approach for breaking plastic waste down to monomers
2025-02-20
Researchers have reported a method for breaking down commercial polymers like Plexiglass into monomers, a form more desirable for reuse. This could help alleviate the growing plastic waste stream. Most current plastic recycling methods rely on macroscopic mechanical shredding, cleaning and reprocessing. As a result, the properties degrade relative to the virgin polymer. Chemical decomposition to the original monomer would enable more thorough purification and then repolymerization to restore ideal performance. Here, Hyun Suk Wang and colleagues report the discovery that in dichlorobenzene solvent, violet light irradiation ...
