"[C]limate change is just a very, very expensive form of tax."

"I believe in climate change caused by human beings. What I'm skeptical about is the glib notion that it means the end of the world as we know it."

"The clock is no longer just ticking, it is banging."

"There is no long-term prosperity without action on climate change."

"The time for seeking global solutions [to climate change] is running out."

"The climate crisis is the existential threat. That's not hyperbole; it's a fact."

"[W]e are killing our planet."

Climate change is "above all, an existential crisis."

"Climate change is one of the greatest challenges mankind faces."

"If we don't take action, the collapse of our civilisations and the extinction of much of the natural world is on the horizon."

"Humanity is on thin ice — and that ice is melting fast."

"We haven't yet exceeded the bounds of viable human civilisation, but we're getting close."

Is Climate Change an Existential Threat?

According to researchers from the University of Southampton, Antarctica has lost sea ice equivalent to the size of Greenland since 2015, marking the largest environmental shift detected anywhere on Earth in recent decades.

According to researchers from the University of Southampton, Antarctica has lost sea ice equivalent to the size of Greenland since 2015, marking the largest environmental shift detected anywhere on Earth in recent decades.

In a paper published Monday, the researchers found that the Southern Ocean's surface water has unexpectedly become saltier rather than fresher, reversing a decades-long trend that had helped protect sea ice from melting since the early 1980s.

In a paper published Monday, the researchers found that the Southern Ocean's surface water has unexpectedly become saltier rather than fresher, reversing a decades-long trend that had helped protect sea ice from melting since the early 1980s.

Additionally, the researchers discovered that saltier surface water allows deep ocean heat to rise more easily, creating a feedback loop where less ice leads to more heat, which leads to even less ice.

This has coincided with the re-emergence of the Maud Rise polynya, a massive hole in sea ice nearly four times the size of Wales, in the Weddell Sea for the first time since the 1970s, signaling unusual current conditions.

Researchers used European Space Agency satellites and underwater robots to monitor these changes in real-time, combining satellite observations with data from floating robotic devices for the first time.

The findings challenge previous climate models that predicted enhanced surface freshening would help sustain Antarctic Sea ice cover, suggesting current understanding may be insufficient to predict future changes.

While these changes are concerning, they highlight the need for better scientific understanding rather than panic. Current climate models clearly need updating based on new satellite data. The focus should be on improving monitoring capabilities and research funding to accurately predict future changes in this complex system.

This dramatic shift highlights a planetary emergency that demands immediate attention. The Southern Ocean's transition to saltier conditions creates an unstoppable feedback loop accelerating global warming. Without continuous satellite monitoring and urgent climate action, we're heading toward permanently reshaped oceans and catastrophic sea level rise.

There's a 50% chance that the minimum Antarctic sea ice extent will be 2.25 million km² in 2030, according to the Metaculus prediction community.
