Researchers Warn Gulf Stream Collapse Could Make Sweden 20°C Colder

A new open letter by 48 researchers warns that a collapse of the Gulf Stream could cause Sweden's temperatures to plummet by up to 20°C within a century, posing severe risks to the region's climate and welfare states.

    Key details

  • • 48 researchers warn of a possible Gulf Stream collapse affecting Sweden's climate.
  • • The collapse could drop Sweden's temperature by up to 20°C within 100 years.
  • • Melting Greenland ice is disrupting ocean currents critical to the Gulf Stream.
  • • Political leaders urged to act to protect Nordic welfare states.
  • • Studies suggest a tipping point may be near, with collapse timelines spanning 2025 to 40 years ahead.

Forty-eight researchers have issued a stark warning to the Swedish government about the potential collapse of the Gulf Stream, which could cause catastrophic climate changes in Sweden and the broader Nordic region. The scientists emphasized that the risk of this ocean current collapse has been significantly underestimated, with a recent study indicating that a tipping point may soon be reached. Should the Gulf Stream collapse, it could result in temperature drops of up to 20 degrees Celsius in Sweden over the next century, alongside a sea-level rise of around one meter.

The researchers pointed out the threat posed by large volumes of meltwater from the Greenland ice sheet disrupting major ocean circulation systems, including the Gulf Stream, leading to irreversible climatic shifts. This development could dramatically alter the mild climate Scandinavia currently enjoys, posing severe risks to modern welfare states.

Johan Rockström, a leading climate scientist among the signatories, criticized Scandinavian political leaders for not adequately addressing these warnings, underscoring the urgency needed to mitigate this potential crisis. While some earlier studies suggested the Gulf Stream collapse could happen as early as 2025, others see a likely timeframe of 30 to 40 years, but the message remains clear: action is crucial now to protect Nordic societies and their environments.
