Floodwater carries dense clouds of sediment, choking the lush seagrass meadows on which these gentle grazers rely.
A climate scientist explains the forces behind the summer’s extreme downpours and dangerous heat waves, and why new locations will be at risk in the coming year.
Millions of mangroves died off along Australia’s northern coast. The cause? El Niño - and the moon’s wobbly orbit causing extremely low tides.
A third La Niña event in a row could bring dangerous conditions for people with allergies – but we’ll need better continuous monitoring to be sure what’s coming in the future.
La Niña is officially here for the third year in a row. You probably associate it with flooding, but how might it affect future drought and bushfires? And could a fourth La Niña be possible?
Catchments are full. Dams are at capacity, soils are saturated and rivers are high. In some cases, there’s nowhere for the rains to go except over land.
Will spring bring an end to the cold and the rain?
Determining whether a region or farm is “in drought” is a longstanding and complex problem which remains important to our future drought response.
Governments have known about the flood risks in the Hawkesbury-Nepean Valley for more than two centuries. All have failed to protect the community.
The collapse of the Atlantic meridional overturning circulation would profoundly alter the anatomy of the world’s oceans and climate. New research explores the consequences.
When Melbourne had to isolate during COVID lockdowns, Greg Moore and his family discovered the pleasure of a very fine fungi-spotting season.
Driving into floodwater is the leading cause of flood-related death. So why do people do it?
Efforts to save the reef aren’t tackling the main cause: climate change. What we need from our next federal government is strong leadership to avert the climate crisis.
Fire season is getting longer, and the result is transforming iconic desert ecosystems. The start to 2022 has been so dire, one governor called for a federal disaster declaration.
This score is a massive four points higher than the year prior. But as La Niña subsides, we’ll quickly feel the long-term warming trend again, with bushfires picking back up next season.
On a hot and humid day, the fan is your friend. But ice cream won’t make the difference you think it will.
Southern Africa’s current above-average rainfall is a climate variability signal - a short-term fluctuation in average wet-season conditions.
Extreme heat over 50℃ is likely to become more common, giving us yet another reason for Australia to act fast on climate change.
Severe coastal flooding inundated islands in the Pacific last week, including the Marshall Islands, Papua New Guinea and Solomon Islands. It’s a taste of things to come.
After one La Niña, the Pacific sometimes retains cool water which enables a second La Niña to form.
