A new study says nearly 40 percent of the total mass of the world’s glaciers is doomed. CNN’s Derek Van Dam looks at some recent events back that up.

A recent scientific study has found that nearly 40 percent of the total mass of the world's glaciers is projected to be lost, regardless of future efforts to halt global temperature increases. This irreversible loss is expected to contribute to a significant rise in global sea levels, with recent events in Switzerland, Argentina, and Nepal illustrating the ongoing impact of glacier melt.

The study warns that if current climate policies remain unchanged, the percentage of glacier mass loss could increase to 76 percent. Researchers emphasize that while the outlook is dire, every reduction in global warming can help preserve more glacier ice, offering hope that stronger action could mitigate some of the damage.

Study: Glaciers on track to lose 40% of their mass

Scientists have a new warning about the effect of climate change on the world's glaciers. They estimate glaciers will lose nearly 40 percent of their mass relative to their size in 2020. And there's nothing we can do about it. CNN meteorologist Derek Van Dam has more. A glacier's partial collapse buries a village in the Swiss Alps. Thankfully, its roughly 300 residents had already evacuated. But even the few homes that weren't engulfed by ice, mud and rock flooded in the aftermath. One resident is still missing. What you see is just something that on paper you knew could happen, but then when you see it, it just takes your breath away. Days earlier, cracking sounds within Argentina's Perito Moreno Glacier. A last second signal before an ice block the height of a 20-story building falls into the water below. Climate change is happening. It's present not only in the melting or retreat of glaciers, but we also see it reflected in the instruments we have installed around the region. And last month, U.N. Secretary General Antonio Guterres issuing a warning to the Nepali government. Record temperatures have meant record glacier melt. Nepal today is on thin ice, losing close to one-third of its size in just over 30 years. These phenomena mark a bleak new reality. A new study says nearly 40 percent of the total mass of the world's glaciers is doomed, even if global temperatures stopped rising today. With this irreversible trend likely to cause a 113 millimeter rise in global sea level, meaning more scenes like those in Switzerland and Argentina in all corners of the planet. But that's assuming matters don't get worse. If world climate policies continue as they are, the study finds that 40 percent figure will jump to 76 percent. The difference between those numbers, one scientist says, is the difference between whether or not countries will be able to adapt to this glacier loss. The study's authors don't want to be alarmist, but rather provide facts and spread an encouraging message. Co-leader Lillian Schuster told CNN her team wants to show we can preserve this glacier ice with every tenth of a degree less of global warming. A beacon of hope for a world prognosis that is nothing short of dire. Derek Van Dam, CNN.
