Dutch Task Force Investigates Potential for Colder Climate Due to Weakening Atlantic Current

A Dutch government task force is investigating a new climate scenario where the weakening Atlantic current could lead to a colder Netherlands, causing more droughts, storms, and sea level rise within 20 years; this challenges the long-held expectation of warming.

What are the broader global impacts of a potential AMOC slowdown, and how do these connect to changes in the Netherlands' climate?

The Atlantic Meridional Overturning Circulation (AMOC), a system of ocean currents influencing Northwest European temperatures, is weakening. New climate models show a higher than previously thought probability of the AMOC slowing or stopping, causing a radically different climate in the Netherlands.

AMOC Weakening Unlikely to Collapse This Century, But Impacts Remain Severe

A new study in Nature suggests the Atlantic Meridional Overturning Circulation (AMOC) will weaken this century due to climate change, but a full collapse is unlikely due to Southern Ocean upwelling; however, a weaker AMOC will still significantly impact global climate.

What are the immediate and specific impacts of the AMOC weakening, even without a complete collapse?

A new study published in Nature suggests that while the Atlantic Meridional Overturning Circulation (AMOC) is expected to weaken this century, a complete collapse is unlikely. The research, using 34 climate models under extreme conditions, indicates that persistent upwelling in the Southern Ocean driven by strong westerly winds compensates for AMOC weakening. This mechanism prevents a total collapse, even under extreme climate scenarios.

What are the immediate implications of January 2025's record global temperature, exceeding the pre-industrial average by 1.75 degrees Celsius, and what does this suggest about the accuracy of current climate models and projections?

Global average temperatures reached record highs in January 2025, exceeding the pre-industrial average by 1.75 degrees Celsius and surpassing the 1991-2020 average by 0.79 degrees. This increase occurred despite the onset of a La Niña weather pattern, which typically cools the planet, raising concerns about the accuracy of climate models and the possibility of surpassing critical warming thresholds.

2024: Hottest Year on Record Exceeds Climate Model Predictions

2024 is the hottest year on record, exceeding 1.5 degrees Celsius above pre-industrial temperatures; this surpasses climate model predictions, largely due to human-caused climate change exacerbated by reduced sulfate pollution from shipping and China.

What factors beyond the expected effects of fossil fuel combustion contributed to the record-breaking temperatures in 2023 and 2024?

The discrepancy between predicted and observed warming, approximately 0.2 degrees Celsius, is significant; this amount typically represents a decade's worth of warming. Reduced sulfate pollution from stricter shipping regulations and decreased pollution in China are partially responsible, yet the primary driver remains human-induced climate change from fossil fuel combustion.

"What is the projected temperature increase in Europe by 2060, and how does this compare to the global average increase in 2023?"

"Europe's temperature could rise by at least 3 degrees Celsius above pre-industrial levels by 2060, based on a new AI-driven analysis. This warming trend is faster than the global average; 2023 was already 2.3 degrees warmer in Europe compared to the global average of 1.48 degrees."

"What caused the 0.2-degree Celsius discrepancy in global warming in 2023, beyond the effects of greenhouse gases and El Niño?"

"In 2023, the planetary albedo, Earth's reflectivity, reached a record low, contributing to a 0.2-degree Celsius warming beyond what was explained by greenhouse gases and El Niño. This reduced reflectivity resulted from a decrease in low-level clouds, which typically reflect sunlight and cool the planet."

Study Finds Atlantic Current Collapse Unlikely This Century

A new study using 34 climate models suggests a complete collapse of the Atlantic Meridional Overturning Circulation (AMOC) is unlikely this century, although a significant weakening is probable, leading to considerable climate impacts but not a European ice age.

How does this study's methodology and focus differ from previous research on AMOC collapse, and what accounts for the differing conclusions?

The study's findings contrast with previous predictions of imminent AMOC collapse. The researchers found that even under extreme climate change scenarios, a secondary current in the Antarctic Ocean would likely maintain the AMOC, albeit weakened, until 2100. This contrasts with studies focusing solely on the North Atlantic.

AMOC Slowdown: Europe Faces Colder, Drier Future

What factors contribute to the AMOC's resilience, even with global warming?

The study, published in Nature, examined 34 future scenarios and found the AMOC unlikely to completely stop, yet a significant slowdown would have similar global consequences to a complete collapse, causing extreme cooling in Europe and reduced rainfall. While increased wind may partially sustain the current, the effects of reduced salinity from melting ice remain a major concern.

What are the contributing factors to the unexpectedly high temperatures in January 2025, beyond the established impact of greenhouse gas emissions?

The record warmth is attributed to increased greenhouse gas emissions, but scientists are investigating additional factors such as the ocean's prolonged response to the 2023-24 El Niño and a potential reduction in atmospheric aerosols. These aerosols have a cooling effect by reflecting sunlight, and their decrease may be exacerbating warming.

How did the decrease in low-lying ocean clouds contribute to the extreme temperatures in 2023?

This reduction in cloud cover, a decade-long trend, amplified warming by decreasing the reflection of sunlight back into space. Areas like the North Atlantic experienced particularly significant cloud cover decline, exacerbating the temperature rise.
