The year 2024, much like 2023, will be remembered as a pivotal moment in the Netherlands’ climate history. The Royal Netherlands Meteorological Institute (KNMI) has confirmed that the Dutch climate experienced a striking warmth over the entire year, with temperatures on par with last year’s record-breaking heat. Remarkably, this marks the second consecutive year that the average temperature has surpassed the previous record, set back in 2023.
A Tale of Two Seasons
While the news of another record-breaking year might come as a surprise, the weather pattern throughout 2024 was quite varied. The summer, which followed a record-warm spring, was perceived as unpleasantly muggy and cool by many in the Netherlands. Months of July and August were notably colder than average, contributing to a seemingly unremarkable summer. However, the remaining ten months of the year more than compensated for this dip, with significantly higher temperatures, ultimately driving up the annual average.
The KNMI’s Climate Stripes Code Unveiled
The KNMI’s announcement arrives alongside the institute’s updated ‘climate stripes code,’ a visual representation of Dutch temperature fluctuations since 1901. Introduced in 2018, the stripes code, inspired by British climate scientist Ed Hawkins, assigns a unique color to each year’s average temperature. The spectrum ranges from dark blue for cooler years to dark red for warmer ones, offering a clear and impactful illustration of the Netherlands’ warming climate.
Karin van der Wiel, a climate scientist at the KNMI and creator of the Dutch stripes code, explains, "By visualizing the entire dataset, you get a striking pattern that demonstrates both the long-term warming trend and the year-to-year temperature variability. It’s an excellent tool for sparking conversations about climate change."
2024: Another Year of Record Heat
Notably, the new stripes code for 2024 features another deep shade of red, mirroring the warmth of 2023. This trend illustrates the Netherlands’ ongoing warming, consistent with global temperature increases linked to the burning of fossil fuels.
In a fitting display, Utrechters were treated to a preview of the KNMI’s latest stripes code on Christmas Eve. The newest version was projected onto the restored Domtower, as part of a winter light art installation.
Global Context: A World Beyond 1.5°C
The лютRed streak¿ extending across the KNMI’s 2024 stripes code echoes a broader global trend. In November 2024, the European climate agency Copernicus warned that global temperatures had risen by an unprecedented 1.5°C above pre-industrial levels—an alarming milestone first outlined in the Paris Agreement. However, Van der Wiel reminds us that direct comparisons between the global and Dutch average temperatures are challenging. "While 1.5°C is a worldwide metric, it’s a slower process. Netherlands warms faster than the global average because it’s a land country, not an ocean.”
Rethinking the Red and Blue: KNMI’s Color Dilemma
As the Dutch climate continues to warm, the KNMI faces a unique challenge: running out of red hues to depict increasing temperatures. Van der Wiel admits, "I’ve been adding darker shades, but how much redder can the stripes get? In England, they’ve switched to black, but we at the KNMI aren’t keen on that approach."
Fortunately, for the global stripes code, a reprieve from the warming trend may be in sight. Following several consecutive El Niño years, which pushed global temperatures upward, 2025 is expected to see a shift towards cooler temperatures as the world recovers.
Back in the Netherlands, forecasting the 2025 average temperature proves more complicated. Nevertheless, based on the unyielding global warming trend, one thing is certain: the days of cool blues that defined the early 20th century are long gone.
Visualizing the Unseen: The Power of KNMI’s Climate Stripes
The KNMI’s climate stripes code, set against the backdrop of another record-breaking year in the Netherlands, serves as a powerful reminder of our warming world. As the stripes turn redder with each passing year, we are confronted with the stark reality of climate change and its consequences—and the urgency to act. By harnessing the potency of visual storytelling, the KNMI’s climate stripes code transforms data into actionable insights, propelling us all to engage with and address this pressing global challenge.
