A heatwave across northern Australia comes as a shock to the system. The impacts of heat are worst in early summer when we’ve had less time to acclimatise, so it’s important to heed health warnings.

Seventy-two per cent of native bumblebee species in North America are cutting their winter hibernation short by timing their emergence to earlier spring onsets.
Processes like La Niña set the scene for the sort of extreme weather that has hit eastern Australia. But what decides which towns and suburbs are hit hardest, and which ones are spared?
Evacuations can save lives, as in the case of post-tropical cyclone Fiona. As more frequent extreme weather events are set to occur, it is important to have evacuation plans in place.
Hurricane Fiona is the most devastating storm to hit Atlantic Canada. International collaboration between ocean measurement institutions is necessary to help efficiently plan responses to hurricanes.
Hurricanes don’t usually maintain high wind speeds as they make their way toward Atlantic Canada. But ocean warming may be linked to the increasing intensity of storms like Fiona.
A project to transcribe Dutch colonial records of the weather in Cape Town can benefit modelling of future climate scenarios and assist in forecasting weather now.
Are severe and extreme weather events on the rise? And does this have anything to do with manmade climate change? The simple answer is: it’s complicated.
