Atlantic currents could recover if climate cools, study says

What this story says

  • An Atlantic Ocean current system weakened by global warming could recover if the climate cools, according to a study by the Danish Meteorological Institute.
  • The study found no sign of an irreversible tipping point for the Atlantic Meridional Overturning Circulation (AMOC), which brings warm water northwards.
  • However, the Greenland ice sheet, which contributes to weakening the AMOC, could not be restored once melted.
  • A disrupted AMOC could still destabilise global rainfall and accelerate sea-level rise, with an estimated 20cm rise from Greenland melt after a 1.5C warming.

Thin on the left so far

None of the 9 outlets with a published leaning rating that ran this story are rated left.

This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.

A system of Atlantic Ocean currents, known as the Atlantic Meridional Overturning Circulation (AMOC), could regain strength if global temperatures decrease, a study by the Danish Meteorological Institute has shown. This circulation brings warm water from tropical regions towards the Arctic, influencing Europe's climate. The research, published in the journal Science Advances, indicated that the AMOC might slow significantly with a substantial rise in global temperature but would recover if warming were reversed. However, the study cautioned that the Greenland ice sheet, a factor in the AMOC's weakening due to freshwater runoff, is not restorable once melted.

While the study found no evidence of an irreversible tipping point leading to a collapse of the AMOC, it noted that a disrupted system could still lead to destabilised global rainfall patterns and faster coastal sea-level rise. Researchers estimated that melting of the Greenland ice sheet following a 1.5C temperature increase could result in approximately 20cm of long-term sea-level rise. The study's lead author, Chuncheng Guo, stated that recovery of the AMOC could take centuries even after temperatures fall, and that preventing warming in the first place is a safer strategy than relying on future cooling.

Disagreement on tipping points

Previous studies have suggested the possibility of an irreversible tipping point for the AMOC. However, the Danish Meteorological Institute study found no sign of such a point, stating that the circulation gradually weakens but immediately regains strength if global warming is reversed. Lead author Chuncheng Guo said, "In our model, we do not see a tipping point leading to a collapse."

What the coverage left out

None of the left-rated reports ran this story. The right-rated reports did not mention the specific journal in which the study was published (Science Advances), nor did they include the specific figure for the AMOC's potential slowdown to around 6 million cubic metres of water per second from 17 million at around 7 degrees Celsius of global warming. The potential limitations of the single-model study and the need for further testing against other models were also not mentioned in the right-rated digests.

  • The centre-rated report led on the study's finding that the Atlantic Meridional Overturning Circulation could recover if the climate cools. It included details about the AMOC's role in bringing warm water northwards and the study's conclusion that there was no irreversible tipping point. The report also mentioned the potential consequences of a disrupted AMOC, such as destabilised rainfall and accelerated sea-level rise, and the estimated 20cm sea-level rise from Greenland ice melt following a 1.5C warming.

  • The right-rated reports highlighted the study's conclusion that Atlantic Ocean currents can recover from severe climate weakening if the climate cools. They noted the AMOC brings warm water towards the Arctic and that the study found no sign of an irreversible tipping point. These reports also mentioned that the Greenland ice sheet could not be restored once melted, and that a disrupted AMOC could destabilise global rainfall and accelerate sea-level rise. The estimated 20cm sea-level rise from Greenland melt following a 1.5C warming was also included in these reports.

Questions about this coverage

How did the left and right cover Atlantic currents could recover if climate cools, study says?
Of the 9 outlets on this story carrying a published leaning rating, 0% are rated left, 22% are rated centre, 78% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 10. The sections above set out what each side emphasised, in its own terms.
Is Atlantic currents could recover if climate cools, study says left or right?
Too few of the outlets on this story carry a published leaning rating to say. 9 of them do, and this site does not characterise a field under 12: at that size one newsroom filing moves the share by ten points. The percentages above are the count as it stands.
Is the coverage of Atlantic currents could recover if climate cools, study says biased?
Atlantic currents could recover if climate cools, study says is one event reported by 10 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which side is not reporting Atlantic currents could recover if climate cools, study says?
When we first saw this story, outlets rated left had barely covered it. Coverage accretes for hours after an event, so that is where to look rather than a verdict — the split above is the current count, and it is the one to read.
Which outlets covered Atlantic currents could recover if climate cools, study says?
10 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
Could the Atlantic Ocean currents recover from climate change?
Yes, a study by the Danish Meteorological Institute suggests that the Atlantic Meridional Overturning Circulation (AMOC) could recover its strength if global temperatures were to decrease. The research indicated that while the current system might slow down due to warming, it could regain its pace if the climate cools.
What is the Atlantic Meridional Overturning Circulation?
The Atlantic Meridional Overturning Circulation (AMOC) is a system of ocean currents that transports warm water from tropical regions northward towards the Arctic. This flow plays a significant role in regulating global climate patterns, including influencing the mild winters experienced in Europe.
Did the study find an irreversible tipping point for the AMOC?
No, the study by the Danish Meteorological Institute found no sign of an irreversible tipping point that would lead to a collapse of the AMOC. The researchers observed that the circulation gradually weakens with warming but can recover immediately if global warming is reversed.
What are the potential consequences of a disrupted AMOC?
A disrupted AMOC could lead to significant global climate instability. Potential consequences include destabilised rainfall patterns across the world and an acceleration of coastal sea-level rise. The study also estimated a long-term sea-level rise of around 20 cm from Greenland ice melt following a 1.5C warming.
