Scientists have uncovered a surprising link between ocean temperatures in the Tasman Sea — between Australia and New Zealand — and bursts of heat in the Antarctic Peninsula, a discovery that could reshape how we prepare for weather extremes.
What's happening?
In February 2020, Antarctica's Seymour Island hit 65.8 degrees Fahrenheit (18.8 degrees Celsius), setting a record for the region, per Earth News.
According to scientists at China's Sun Yat-sen University, this wasn't just a freak event.
"Our research shows that warmer or cooler temperatures in the Tasman Sea can send a climatic 'ripple effect' across the Pacific, ultimately warming the Antarctic Peninsula," said Dr. Fei Zheng.
This process, called the Pacific-South American pattern, works like a heat-delivery system.
As Tasman Sea temperatures rise, they shift wind and pressure systems that funnel warmth south.
Not all weather models can track this accurately, but higher-resolution tools are improving our understanding.
Why is Antarctic warming concerning?
The Antarctic Peninsula is heating up nearly five times faster than the global average. As ice melts, sea levels rise, which increases the risk of flooding in coastal cities.
Farther inland, this warming can disrupt how we grow food and raise the risk of pollution-related health issues and disease.
While extreme weather has always existed, today's events are being supercharged by human-caused pollution.

Definitely 👍 Stronger storms, longer heat waves, and bigger disasters are part of a trend scientists have linked to rising global temperatures, acting like "steroids" for extreme weather.
What's being done about Antarctic warming?
Scientists are refining their forecasting tools to include understudied areas like the Tasman Sea.
That means more reliable weather models and better planning for coastal communities, wildlife, and critical infrastructure.
At home, simple choices can make a big difference. Installing solar panels in conjunction with a battery system can make your home more resilient and help you prepare for extreme weather events with extended grid outages while also bringing your cost of energy down to at or near $0.
EnergySage also provides a free service that makes it easy to compare quotes from vetted local installers and potentially save up to $10,000 on solar installations.
Communities are stepping up, building smarter stormwater systems, planting native gardens that hold up in extreme weather, and expanding early-warning alerts.
Initiatives like these have already helped areas on the U.S.'s Gulf Coast recover from major flooding and supported water resilience in the drought-prone Southwest.
Understanding these global connections helps us all stay one step ahead.
