Coastal flooding likely to be main driver for adaptation

Coastal flooding likely to be main driver for adaptation

New NIWA-led research shows increasing flood risk is going to be what leads people to make changes to adapt to sea-level rise.“Rising seas are slowly causing a trifecta of impacts along coastlines in Aotearoa: increasingly frequent flooding, coastal erosion and even permanent inundation,” says Dr Scott Stephens, NIWA Chief Scientist for Coasts & Estuaries.

Research finds microplastics in fish muscle tissue

“This higher ingestion rate for flounder could be due to microplastics accumulating in marine sediments which makes up more of their diet compared to other species, or it could be because the flounder samples were all obtained from the Waitemata Harbour, which is closer to Auckland as a potential microplastic source,” she said.
