FFor unknown 18,600 glaciers cover around 66,000 km2 of our planet's surface, located in a total of 50 UNESCO World Heritage sites. In total, this represents 10% of the total glacier area on Earth. Half of humanity depends directly or indirectly on glaciers as a source of water for domestic use, agriculture and energy. Glaciers are also pillars of biodiversity and feed many ecosystems. However, due to CO2 emissions that are increasing global temperatures, many of these glaciers have been melting at an increasingly accelerated rate. Especially since 2000. Currently, in fact, about 58,000 tons of ice are lost each year. According to UNESCO data , the glaciers that are melting the fastest are those in the Three Parallel Rivers Protected Areas of Yunnan (China). There is also a high probability that the glaciers of all World Heritage sites in Africa, such as those in Kilimanjaro National Park and Mount Kenya, will disappear by 2050.
By this date we will also see European glaciers completely melted, such as those in the Pyrenees: the Monte Perdido glacier (France, Spain) and the Dolomites (Italy). Ordesa and Monte Perdido, Aragon Ordesa and Monte Perdido, Aragon. By Jose Stopping this bleeding is not an easy problem. In addition to drastically reducing Colombia Mobile Number List carbon emissions, UNESCO advocates the creation of an international fund for glacier monitoring and conservation. However, we are still far from these measures being agreed upon internationally, so the glaciers continue to release liters and liters of water, as David Farrier explains in his book Traces : In total, there is enough ice locked in the planet's ice sheets and glaciers for sea level to rise 60 meters from today's level. If all the ice melted, the oceans would redraw the world map. North America would sink on its west side; South America would be consumed by the growth of huge deltas inland.
The United Kingdom would be a very reduced version of what we know today. In Australia, the water would enter through the Spencer Gulf towards the Red Center of the continent. China's coast would retreat to Beijing, 150 kilometers from its current position. As if that were not enough, the melting of glaciers is releasing organic material that had remained encapsulated for thousands or millions of years. In fact, a new study led by Arwyn Edwards of Aberystwyth University in the United Kingdom suggests that glaciers that are melting rapidly due to global warming are also releasing tons of unknown bacteria . It is still unknown whether this could represent a danger to human health, and also to the health of planet Earth itself.
