A UN meeting this week considered a motion on a suite of technologies known as ‘solar radiation modification’, but no consensus could be reached on the controversial topic.

Last year was the hottest in recorded history. That heat led to a range of unusually intense weather events across Australia.

The early heat melted snow and warmed rivers, heating up the land and downstream ocean areas. The effects harmed salmon fisheries, melted sea ice and fueled widespread fires.
Sea ice around Antarctica has always followed a predictable seasonal cycle. Now, we’ve experienced a sudden dramatic loss, and the changes are here to stay.
Climate change and the nuclear threat are raising concerns about our planet’s future ability to support human life. If we launch a species survival mission, who should go?

Sea ice extent in July 2023 has been around 10% below last year’s record low for the month.
Landfast ice ‘breaks out’
More trouble in Antarctica: the extent of frozen seawater fastened to the coast (called landfast ice) hit a record low in March 2022. If this trend persists, the consequences could be catastrophic.
The Indian Ocean’s heat is having effects on land, too.

Drought in Europe, dwindling Arctic sea ice, a slow start to the Indian monsoon – unusually hot ocean temperatures can disrupt climate patterns around the world, as an ocean scientist explains.

We are on a trajectory that takes Earth across thresholds humans have never experienced, into a climate where Antarctica’s ice shelves can no longer exist, leading to several metres of sea-level rise.
The Weddell Sea helps power the great ocean conveyor, which moves heat, carbon dioxide and nutrients around Earth’s ocean basins.
Freshening seawater around Antarctica is disrupting a global ocean conveyor which regulates the climate.

A short history of predicting an ice-free Arctic – and why you should listen to this one.
Scientists have detected a 30% slowdown of the deep ocean currents that form in Antarctica, with profound consequences for Earth’s climate, sea level and marine life.
The world’s oceans regulate our climate, but they are entering uncharted territory, with record surface warming and changes to Antarctica’s deep meltwater which drives global currents.

In the years since the Supreme Court rejected Kivalina’s appeal on May 20, 2013, the community’s search and rescue team has faced increasing climate disasters: ‘We just can’t adapt this fast.’
Rain and warm air make it harder for sea ice to grow.

Atmospheric rivers can melt fragile new sea ice. When these storms arrive in waves, the sea ice doesn’t have a chance to recover.
Penguins are at risk as a warming climate affects sea ice in Antarctica.

Emperor penguins survive in a ‘Goldilocks zone’ between too much sea ice and too little. Climate change is having an impact.
Scenes like this one are becoming increasingly common in the Arctic.

Polar bears are increasingly seeking sustenance in human trash because of melting sea ice and a loss of hunting opportunities. The result is a rise in human-bear conflict – and dead bears.
The sound of the marine environment has been underestimated, mainly because it is not audible to the human ear.
The ocean is often considered a silent universe. But many recent studies highlight the importance of the soundscape for many marine species, both large and small.
Sea lions, otters and birds were some of the many wildlife species that were hit hard by the 1989 Exxon Valdez oil spill in Alaska. Oil spills like these expose the wildlife to new contaminants and can be fatal.

ToxChips study the changes in the DNA of animals exposed to contaminants, like those found in oil spills.
