Climate change on the planet, coupled with rising sea levels destroy half of the sandy beaches of the Earth by 2100, reports article published in the journal Nature Climate Change. Even in if humanity can significantly reduce the level planet fossil fuel pollution, which is the main cause global warming, more than a third of all sand the coastlines of the planet will disappear, thereby causing significant damage to coastal tourism in several countries of the planet. Really have humanity will soon be unable to relax on the famous resorts?
Where do the beaches disappear?
It seems that soon we will forget about the summer vacation on the sea coast. Specialists from the Joint Research Center European Commission forecasts significant reduction in beaches by to the whole world. Once again, the fault is global warming, which is accused not only of the destruction of marine resorts, but also in an unprecedented heat in Antarctica (perhaps we can rest soon we will go there), and even in a change in character spiders. In a new study, scientists argue that the absence beaches can adversely affect climatic conditions of our planet. So, according to their new report, sandy beaches may to be not only a great goal for summer tourism, but also to play a huge role in containing coastal storms and floods. Without them natural defense, humanity is at risk of facing extreme weather events threatening coastal cities and countries with devastating consequences.
The authors of the article claim that some countries, such as the United States, already planning extensive defense systems, however in in most countries of the world such large-scale engineering schemes will be an impossible task for a number of reasons. So, one of these countries will be Australia, which over the next 80 years at risk of losing nearly 15,000 kilometers of his famous beaches. Australia will be followed by Canada, Chile, already mentioned above. United States, China, Mexico, Argentina, Russia, Brazil and India.
The published article also mentions that sandy beaches occupy more than a third of the entire world coast, often located in the most densely populated areas. In order to estimate the rate of disappearance of coastlines, scientists analyzed data from satellite images over the past 30 years, which showed the possibility of erosion in accordance with two scenarios of climate change.
One of the proposed scenarios suggests that emissions carbon will continue to grow further; less frightening scenario relies on humanity slightly exceed the current rate of global warming, but not will go beyond the limits provided for in the 2015 Paris Agreement. The results of the simulation surprised scientists: according to first estimates, by 2100 the world risks losing almost half of all the sandy beaches of the planet, taking a rest on the coast (perhaps even in the Black Sea) is quite an expensive and inaccessible occupation. A more likely version showed that by 2100 “only” 30% from the entire coastline will go under water, and most of it – already over the next 30 years.
Researchers believe that no matter what it is humanity’s scenario that will burn fossil fuels could be even more catastrophic than that assumed currently. Is it worth the wait climatic apocalypse in this case? Scientists haven’t yet. answer, however, the accelerating melting of glaciers in a number of regions planets, including in the Himalayas, Antarctica and Greenland, may lead not only to a decrease in the area of sandy beaches, but also to erosion of deltas in water bodies around the world. And here it is may lead to more sad consequences for us than reduction in the area of beaches suitable for recreation.
