It has been a summer to remember, but not in a good way.

A weekly update describing soil moisture patterns across the country to show where dry to extremely dry conditions are occurring or imminent. Regions experiencing significant soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought.

New research suggests large-scale wildfires may be changing the chemical makeup of our atmosphere. Jessica Rowley explains.

Beachgoers could be safer thanks to a new technology with the potential to give real-time updates of rip currents.

Prior to 15 January, Hunga Tonga-Hunga Ha'apai was a little-known undersea South Pacific volcano with a long name. Within 24 hours, it  was a global phenomenon – the site of the largest atmospheric explosion in almost 150 years. Jessica Rowley looks at why a remote Tongan volcano took the world by storm.
