Europe Takes Heat: Top 10 Fastest-Warming Countries Revealed

According to recent United Nations figures, the ten nations with the most significant rises in temperatures are all located in Europe.

All of these European countries, such as Switzerland and Ukraine, saw temperatures climb more than 2.5°C above the 1951-1980 average in 2023.

The analysis of the decade-long average from 2014 to 2023 indicates that for ten consecutive years, up until 2023, the group of 15 nations with the most significant temperature increases also comprised solely European countries.

How quickly is Europe heating up relative to the rest of the globe?

Based on the UN Food and Agriculture Organization (FAO) data regarding changes in land temperatures, the average yearly increase in global land temperature was recorded at 1.8°C higher than the 1951–1980 reference point in 2023.

This represents the most significant increase in temperatures documented so far. Moreover, it’s even more alarming that the past nine years, beginning from 2015, have seen the hottest average global temperatures on record.

The highest temperature increase was observed in Europe, where the mercury climbed by 2.4°C. This represents the seventh occasion within the last nine years that regional temperatures have exceeded 2°C.

The 1.5°C cap set by the Paris Agreement Was surpassed across all regions in 2023, with the exception of Oceania, where there was a rise of only 0.9°C.

In which nations were the most significant rises in temperatures documented?

Out of 198 countries and 39 territories, Svalbard And in 2023, the Jan Mayen Islands in Norway stood out as they recorded the largest temperature rise globally, with an increase of 3.6°C.

"We shouldn't place too much importance on short-term temperature data, particularly yearly stats for smaller areas, due to the impact of internal variability," says Sebastian Sippel, a professor specializing in climate attribution at the Leipzig Institute for Meteorology, speaking with Euronews Green.

Moldova, Ukraine Andorra, Switzerland, and Belarus all saw temperature increases surpassing 2.7°C relative to the 1951-1980 baseline.

Within the European Union, both Romania and Slovenia experienced the largest increase in yearly temperatures, amounting to 2.62°C.

Out of 49 countries and territories in Europe, 27 made it into the top 30 list for the most significant temperature rises. Included in this group are France with an increase of 2.59°C, Spain at 2.57°C, Russia at 2.53°C, and Germany at 2.44°C.

Warming was strongest in western and eastern Europe. Only three non-European countries made the top 30: Kazakhstan (2.58°C), Morocco (2.56°C) and Tunisia (2.4°C).

This indicates that Europe is heating up significantly quicker compared to most other areas around the world.

Francesco N. Tubiello, who serves as a senior statistician and team leader at FAO’s Environment Statistics Unit, points out that this situation arises due to Europe (encompassing Russia within its total figures) having the most extensive land area located at northerly latitudes.

Which European nations remained more temperate in 2023?

Iceland And notably, the Faroe Islands stood out in Europe as they experienced the lowest warming in 2023, with temperatures rising less than 0.65°C.

Norway, Sweden, and the UK came next with the least increase in temperatures, showing an annual rise of 1.2°C to 1.5°C.

"Sippel notes that countries adjacent to the Atlantic Ocean generally exhibit a minor temperature change, whereas those stretching into northerly (Arctic) areas usually demonstrate a more significant rise in temperatures," he explains.

Rebecca Emerton, a climate scientist at the Copernicus Climate Change Service (C3S), points out that this variation can stem from various elements like atmospheric circulation patterns, oceanic impacts, and localized aspects including snow coverage, soil dampness, and geographic features.

10-year average: What explains Europe's rapid temperature increase?

Experts stress the significance of analyzing long-term patterns, so we computed the decadal mean for 2014-2023, which represents the latest complete ten years of data. Throughout this timeframe, the leading 15 nations and regions experiencing the steepest rise in temperatures are also found within Europe.

" Europe has been heating up at a rate double that of the global average, making it the quickest-warming continent globally," according to Emerton.

"The Arctic is warming at the quickest rate," she says. According to Copernicus's 2023 European State of the Climate report. report examines the factors behind this, such as the percentage of land in the Arctic region and alterations in air currents that lead to more common summertime heat waves.

The ESOTC utilizes the 1991-2020 baseline; however, it doesn’t provide temperature variations data for individual countries.

"Due to Arctic amplification, northern areas tend to heat up faster than the global average, and numerous European nations are situated quite far north," Sippel clarifies.

The Arctic is experiencing much more rapid warming compared to the global average. This occurrence, known as Arctic amplification It is fueled by the reduction in sea ice, which increases the transfer of heat from the ocean to the atmosphere.

Dr. Robin Lamboll, a research fellow at Imperial College London, also highlights how the size of a country can influence temperature fluctuations.

"European countries tend to be smaller compared to those elsewhere, and this means they're more prone to experiencing significant fluctuations in temperature. This occurs because temperature variations aren’t smoothed out across such vast regions," explains Lamboll.

Erik Kjellström, who is a professor at the Swedish Meteorological and Hydrological Institute, proposes that the decrease in atmospheric aerosols might be one reason why Europe has experienced greater warming compared to many other regions.

" Europe has simultaneously reduced its aerosol emissions, often referred to as smog. While this leads to cleaner air, these particles previously helped block sunlight temporarily. Consequently, areas with decreased historical smog experience extra warming," according to Lamboll.

The quickest temperature increase in European nations within ten years

The 10-year average highlights Svalbard (Norway) as an exceptional anomaly, with a significant 3.44°C rise in temperature relative to the 1951-1980 baseline. This leap surpasses all other regions considerably.

Daniela Schmidt, a professor at the University of Bristol’s School of Earth Sciences, points out that regions closer to the equator experience less warming, whereas areas nearer the poles see greater warmth (a phenomenon known as polar amplification). "Consequently, we observe increased heating toward the poles," she notes. Svalbard ,” she says.

Belarus (2.29°C), Russia (2.27°C), Estonia (2.26°C), Latvia (2.24°C), and Lithuania (2.24°C) stand out as some of the regions experiencing the most rapid temperature hikes, placing Eastern Europe and the Baltic countries at the forefront of climate change impacts.

Central and Western Europe are experiencing rapid increases in temperatures as well. Countries such as Germany (with an increase of 2.14°C), Poland (showing a rise of 2.15°C), and Switzerland (demonstrating a change of 2.16°C) show pronounced trends. Meanwhile, Belgium, the Netherlands, and France have each seen their average temperatures climb above 2°C when compared to the baseline period from 1951 to 1980.

In contrast to northern and eastern parts of Europe, Southern Europe and regions around the Mediterranean are experiencing a more gradual increase in temperature. The countries showing these trends include: Italy with an increase of 1.81°C, Spain at 1.78°C, Portugal at 1.65°C, Turkey at 1.59°C, and Greece at 1.29°C.

"The Earth’s surface has experienced greater warming compared to the oceans. This occurs because oceans can store heat within their depths and require considerable time to become warmer, while the shallower regions of land absorb heat much faster," explains Lamboll.

Among European nations, Iceland has experienced the smallest increase in temperatures, remaining slightly under 1°C warmer. Following closely behind are the United Kingdom at 1.28°C, the Isle of Man at 1.18°C, Ireland at 1.16°C, and the Faroe Islands at 1.06°C, all recording some of the lowest increases in mean temperature levels.

NASA Reports Unexpected Surge in Sea Levels Globally in 2024

In 2024, which has been recorded as the warmest year ever, sea levels have escalated beyond expectations, as reported by NASA. This rise can be linked to exceptionally elevated seawater temperatures along with the thawing of glaciers.

This increase is attributed to climate change caused by human activities, with rising temperatures on Earth causing higher sea levels because of greenhouse gases being released into the atmosphere.

NASA stated that based on satellite data, sea levels climbed by 0.59 centimeters in 2024, exceeding the forecasted figure of 0.43 centimeters. In the last thirty years, sea levels have gone up by 10 centimeters. While the primary cause remains the thawing of glaciers and ice sheets, one-third of this increment in 2024 can be attributed to the heat-induced expansion of ocean water as global temperatures soared.

Specialists forecast that sea levels will keep increasing, posing risks to coastal areas and islands.

Winter Ice Path Vanishes for 7 Years: Is Global Warming to Blame?

SUWA, Nagano — For the seventh consecutive winter, the natural occurrence known as "Omiwatari" has failed to materialize on Lake Suwa in Nagano Prefecture. This phenomenon involves ice formation on the lake’s surface splitting into a pattern resembling mountain ranges. Experts suggest that climate change might be contributing to this absence.

Based on records dating back to the Muromachi era (from 1336 to 1573), the frequency of winters lacking the "ake no umi" phenomenon has significantly increased since 1951. Kiyoshi Miyasaka, the 74-year-old head priest at Yatsurugi Shrine located in the city of Suwa within the prefecture, noted that "The effects of climate change and global warming are clearly visible on the lake."

It is said that according to legend, Omiwatari was the path taken by Takeminakata, the male deity of Kamisha Shrine within the Suwa Taisha shrine complex in Suwa, when he visited the goddess Yasakatome at her shrine, Shimosha Shrine, located in the nearby town of Shimosuwa. Because of this, it is often referred to as the “divine path of love.”

Miyasaka states that the Omiwatari was initially documented in 1397. These records were preserved in documents handed down through the Moriya family, who formerly led the Kamisha Shrine of Suwa Taisha. Following a temporary halt, annual documentation began again in 1443 during the middle Muromachi period, marking this as the 583rd instance of recording whether it occurred or not.

Over eight decades, from 1936 onwards—accounting for five missing years—"Ake No Umi" has taken place 81 times. Since 1951 specifically, within this 75-year span, it has happened 40 times. Notably, after the year 2000, this occurrence seems to be less frequent; out of these recent years, only 18 experienced the Omiwatari phenomenon. Importantly, it hasn’t appeared again since Japan transitioned into the Reiwa era in 2019. Concerned about this trend, Miyasaka remarked, “The traditional sights of Lake Suwa we’ve known might vanish soon. Soon enough, ‘Omiwatari’ could merely remain a legendary memory.”

This year also saw a scarcity of extremely cold days. On January 20, at a weather station located on the southern shore of the lake—a time typically considered the coldest day of the year in Japan—the thermometer read 3.2 degrees Celsius for the water temperature and zero degrees Celsius for the air. These figures matched those usually recorded around late March. Despite a frigid spell from February 9-10 causing temperatures to drop to -10°C, leading to widespread freezing across most of the lake’s surface, significant portions thawed again the following day. As forecasts did not predict additional cold fronts, officials termed this season an “akénoumi.”

On February 15th, Miyasaka announced the absence of an Omiwatari at his shrine. However, he cheerfully remarked afterwards, "Even though we didn’t have the Omiwatari this time, it’s invigorating to feel that spring has arrived."

The Ake no Umi Winters took place over the most extended consecutive duration of eight winters from 1507 to 1514, which falls within the Sengoku (Warring States) era of the late fifteenth and early sixteenth centuries. During this period, each year’s absence of Omiwatari was briefly documented in contemporary records. This prolonged sequence ranks as the second-longest; the next longest series spans six winters, occurring continuously from 1992 to 1997.

Miyasaka hypothesized that the eight-year gap occurred during the tumultuous times of war, suggesting it might not have been an appropriate moment for the ceremony. He further commented, “Considering this as the second longest interval, we should contemplate the impacts of global warming. Often, people view climate change as though it’s happening far away from them; however, we must acknowledge that even our own Lake Suwa is undergoing transformations—such changes are evident through the absence of ice cover on the lake. My wish is for everyone to reflect upon these findings.”
