Global warming has been reversed but glaciers lead to recovering for centuries, revealing the study
The study predicts the scenario of extreme overcoming the evolution of glaciers, where global temperatures continue to rise, reaching 3 ° C in 2150, which will be stabilized to 1.5 ° C around 2300.

Mountain glaciers are not recovering from defrost for centuries, although human intervention is able to cool down, according to a study published on Monday Nature climate change.
Investigations headed by Bristol University (United Kingdom) and University of Inbruck (Austria), part of a project ‘offering’ from the European Union (EU) “Excessively” The weather, when the planet’s heating exceeds 1.5 ° C, is the period in the middle of the century or before.
The study predicts the scenario of extreme overcoming the evolution of glaciers, where global temperatures continue to rise, reaching 3 ° C in 2150, which will be stabilized to 1.5 ° C around 2300.
Shows that the results are a condition of glaciers It is more worse than in the world that stabilizes temperatures in 1.5 ° C without exceeding it, Another 16% glacier is lost up to 2200 and 11% up to 2500, along with 35%, already soluble at 1.5 ° C.
In addition, this excess molten water will eventually reach the surface of the glacier, according to a study by the EFE agency quoted.
“The current climatic policies are putting the earth closer to 3 ° C., however, that such a world is very bad for glaciers, in which the 1.5 ° C limit is placed,” said Fabian Mucian, Associate Professor at Bristol University.
The goal is to know if the planet is cold: “Is this the question of many people asks if glaciers will grow again in our lives or in our lifetime? Our research is unfortunately,“The researcher was warned.
Increased global temperatures indicate that the boundaries of the Paris Agreement are likely to overcome the boundaries of a decade. For example, The hottest and the first calendar year exceeded the 1.5 ° C mark on Earth last year.
The investigation used a pioneering model developed at the University of Bristol, which mimics past and future changes in all the glaciers in the world — excluding two layers of polar ice-and combined with global weather expectations made by the University of Bern (Switzerland).
“Great polar glaciers have been noticeable for several centuries, although not millennials, but for small glaciers such as alps, Himalayas and tropical Andes to recover from excess of 3 ° C.
In these mountainous areas, the water of the glacier’s digs is very important for the lower classes, especially dry seasons. When the glaciers are dissolved, they temporarily release more water, called “peak water” glacier.
“If glaciers grow again, they will start storing water in the form of ice, which means lower lower water. We call this ‘water of valley’ effect to contrary to ‘peak water’.
For the myosian, “More than 1.5 ° C, even temporarily, causes the loss of glaciers for centuries.”
“Our study shows that most of the loss will not be repelled, even though temperatures have returned to a safe level later. We will postpone the reduction of emissions, and we will overload more with the recovery of future generations.”
