In response to the newest analysis, glaciers worldwide have misplaced 5% of their quantity since 2000.
A examine printed by 35 groups, together with the French National Center for Scientific Research (CNRS), reveals that on average, this equates to a yearly loss of 300 billion tons of ice. The publication states that that is roughly the identical as shedding three Olympic swimming swimming pools’ value of ice each second.
As local weather change continues to snowball, findings comparable to these ring the alarm bell for humanity. With 2024 being the hottest year on record, maybe this will probably be one of many research to make 2025 the 12 months of efficient and lasting local weather motion.

What Did The Glambie Glacier Report Uncover?
Ice loss is accelerating at alarming charges
The examine, entitled “Community estimate of global glacier mass changes from 2000 to 2023,” was printed within the journal Nature on Feb. 19, 2025.
Orchestrated by the international consortium Glambie, the analysis undertaking had a number of targets in accordance with the entity, together with:
- Outline a set of standards to standardize the evaluation and its uncertainty
- Accumulate and analyze regional assessments from the group throughout the vary of obtainable strategies
- Produce and publish a consensus estimate at regional and international ranges
- Work will result in a set of suggestions for standardized future assessments
The examine discovered that not solely was file ice mass loss occurring in 2024, however the identical had been the case for the 2 years earlier. In different phrases, every year retains breaking the final 12 months’s record-breaking figures.
The Pyrenees and Alps are dwelling to probably the most ice mass loss. In less than 25 years, these regions have lost 40% of their total volume — actually, climate change forced popular French ski resorts in the Alps to close in 2024. From the primary half of the examine’s interval (2000-2011) to the final half (2012-2023), annual ice loss worldwide elevated by 36%.
Altogether, knowledge units like these replicate scientists’ longstanding warnings that worldwide soften is accelerating.
Satellite tv for pc knowledge was mixed with measurements of each glacial area on the planet for the examine. Nonetheless, the Antarctic and Greenlandic ice sheets had been disregarded. Their giant dimension resulted in delayed local weather change-caused ice loss and due to this fact aren’t correct representations of danger in comparison with different glacial areas.

How Do Glaciers Have an effect on Local weather Change?
Ice loss is devastating the planet in a number of methods
The true influence of glacial ice loss is multifaceted as a result of interconnected nature of the planet’s local weather methods.
For one, glaciers act as reflective surfaces that cool the planet, bouncing heat back into space. The impact is just like the best way that sporting white clothes retains one’s temperature down. On the flipside, sporting darkish clothes heats one up, simply as darkish surfaces of the planet improve warming.
When glacial ice is misplaced, it reveals much less reflective surfaces that not solely don’t bounce again warmth however take up it and speed up local weather change, due to this fact inflicting extra glaciers to lose ice.
As meltwater trickles down through the ice in the warming climate, it causes holes to form in the glacier, granting the hotter water a pathway to the ocean. The plume from the glacier base to the ocean is extra light-weight than ocean water resulting from its lack of salt, which makes the meltwater rise to the floor and churn hotter seawater to the floor. This solely additional melts the glaciers and causes calving, or when ice breaks off in giant chunks and types icebergs.
This, for apparent causes, raises sea ranges. Nonetheless, this isn’t the one influence glacial loss has on the ocean.
As freshwater is added to it, the ocean’s movement methods are disrupted. This includes the Atlantic Meridional Overturning Circulation or the AMOC, which distributes heat globally and regulates weather systems. When this life-saving mechanism is damaged, storms comparable to hurricanes grow to be extra frequent, excessive, and unpredictable.
For instance, the AMOC keeps the climate mild and livable in Western Europe and other highly-populated areas around the planet. When disrupted resulting from glacial ice loss, these crowded and fragile areas are prone to climate methods they’ve traditionally not been uncovered to and ready for.
Although life has for millennia discovered a method by way of planetary shifts — new research shows that Paleoindians used unique tools to survive extreme climates — these transformations have additionally led to dying and shifts in dominance, together with that of the dinosaurs, which might be able to credit their power to climate change.
Although humankind has enjoyed its own ruling era, the Holocene, for 11,700 years now, maybe the tables are turning.

Why Is The Glambie Glacier Report A Large Deal?
As local weather change continues, analysis will probably be key in combating the fee
Because of the “range and complementarity of the strategies used,” in accordance with the CNRS, knowledge gathered through the examine is taken into account to be fairly dependable, even contemplating the difficult subjects at hand. This accuracy will allow scientists to watch glacial soften at elevated charges not solely extra frequently, however from a hyper-informed standpoint.
This publication can be slated to be included within the upcoming Intergovernmental Panel on Local weather Change (IPCC) report, which is able to go stay in 2029.
The following IPCC launch will probably be particularly noteworthy, because it drops simply forward of 2030, which has lengthy been labeled because the 12 months of no return. In different phrases, on the finish of this decade, scientists imagine that no matter injury we’ve accomplished to the planet will probably be largely irreversible if we hit sure tipping factors. As a way to keep away from this, humanity must restrict international warming to 1.5°C, or 2.7 levels Fahrenheit.
Nonetheless, last year’s record-breaking heat alone surpassed this limit, which was set by the 2015 Paris Climate Agreement — not solely was 2024 the most well liked 12 months since record-keeping began in 1850, nevertheless it was suspected to be the most well liked within the final 125,000 years.
It was throughout these 12 months that 27 climate disasters occurred, every costing the USA no less than $1 billion in damages. Hurricane Helene alone put the nation again $79.6 billion and killed 219 folks. In complete, disasters in 2024 value the U.S. $182.7 billion.
Regardless of these pricey and lethal occasions, the world continues its march towards elevated disasters, breaking tips set by climate-saving plans contrived by scientists and international superpowers.
Merely hours after taking office in January 2025, President-elect Donald Trump took to a Capital One Arena to sign the order that pulls the U.S. out of the 20215 Paris Climate Agreement. On stage, he made the argument that the accords burden the American economic system.
This was accomplished in opposition to the backdrop of the raging Los Angeles fires, which, with a $250-$275 billion price tag, are the most expensive natural disaster in the nation’s history — the price of the fires formally surpasses Hurricane Katrina’s $200 billion in damages.
Meteorologists are warning governments of how climate change is impacting natural disasters, stating that they’re making them extra excessive, frequent, lethal, and due to this fact, pricey.
As talked about, glacial ice loss particularly exacerbates the difficulty, so having an in depth and correct understanding of the phenomenon can arm scientists with useful knowledge; knowledge that reveals the place the world is on its path to disaster, and the way a lot time is left to alter course.
The Glambie report gives this, and maybe, will encourage lawmakers to get nations on monitor to fight local weather change. Or, it would simply be one other alarm bell that’s left ignored by probably the most highly effective folks on the planet as wildfires, hurricanes, sea rise, and extra eat away on the economic system, land, and lives of their communities. Solely time will inform.
