Study Predicts UK Temperatures Could Plummet to -30°C If Gulf Stream Collapses Amid Climate Crisis

UK Faces -30°C Freeze if Gulf Stream Collapses, Warn Scientists

The UK could face Arctic temperatures as low as -30°C if climate change disrupts the Gulf Stream, warns a new study. This scenario, reminiscent of the film The Day After Tomorrow, would see Britain’s climate resemble northern Canada’s, with extreme cold, expanded sea ice, and fiercer winter storms.

Key Findings

Researchers modeled the impact of a collapsed Atlantic Meridional Overturning Circulation (AMOC)—the system that includes the Gulf Stream—coupled with 2°C global warming. Their results predict:

• Edinburgh: Nearly half the year below 0°C, hitting -30°C extremes.
• London: Temperatures plunging to -19°C, with 60+ additional sub-zero days annually.
• Norway’s west coast: Potential lows of -40°C.
• Oslo: A chilling -48°C.

The AMOC’s Role

The AMOC acts as Earth’s oceanic "conveyor belt," moving warm tropical water northward and moderating Europe’s climate. Freshwater from melting ice caps could stall this system, triggering abrupt cooling.

AMOC Fact Box

• Function: Transports heat from tropics to northern latitudes.
• Collapse Mechanism: Freshwater influx reduces ocean salinity, stopping warm water flow.
• Impact: Without AMOC, Europe loses its mild climate buffer.

Expert Warnings

Lead researcher René van Westen stressed, “Every fraction of a degree of warming brings us closer to AMOC collapse.” Co-author Michiel Baatsen highlighted Edinburgh’s drastic shift: “164 days below freezing—a 133-day increase from pre-industrial times.”

While summers may warm slightly, winters would grow harsher, with more storms and sea-level rise. Agriculture, infrastructure, and energy systems would struggle under prolonged freezes.

A Call for Action

Gareth Redmond-King of the Energy and Climate Intelligence Unit urged: “Net-zero emissions are the only way to avert disaster.” Dr. Bablu Sinha called the findings “plausible,” while Prof. Jon Robson warned of “sharp temperature drops and increased storminess.”

Caution Amid Predictions

Some experts, like Dr. Alejandra Sanchez-Franks, note that observational data hasn’t yet captured an AMOC tipping point. However, the study underscores the urgency of mitigating climate risks.

Conclusion
The research, published in Geophysical Research Letters, paints a stark future unless emissions are slashed. As van Westen states: “Europe faces a freezing fate if we ignore this planetary emergency.”
