Some ant species that can only survive indoors in cooler regions could begin to move outdoors due to climate change, according to a new study. It is among the first studies  to show how global warming may increase the risk of invasive species by enabling indoor-dwelling insects to expand into outdoor environments.

Deaths by suicide and drug overdose significantly increased in the aftermath of the August 2023 Maui wildfire, according to a new study published in the Journal of the American Medical Association (JAMA). The study, led by Alex Ortega, dean of the Thompson School of Social Work and Public Health, and Keawe‘aimoku Kaholokula, chair of the Department of Native Hawaiian Health, in the John A. Burns School of Medicine, both at the University of Hawaiʻi at Mānoa, along with Jonathan Purtle, associate professor at New York University’s School of Global Public Health, is one of the first to show that wildfires can lead to immediate deaths from suicide and drug overdose.

Climate change is starving the Arctic Ocean of essential nutrients, with the region's six largest rivers now delivering far less of the type of nitrogen that marine ecosystems need to survive.

University of Queensland research shows emissions from the global chocolate industry could be reduced by growing more shade trees over farms in the region that supplies 60 per cent of the world’s cocoa.

Hot air is just one contributor to heat stress. Health experts say we need a radical rethink to prevent more deaths during heatwaves.
