Антарктику ожидает беспрецедентная катастрофа

В целом 34% площади всех шельфовых ледников Антарктики, то есть, полмиллиона квадратных километров, окажутся на грани разрушения.

Исследователи Университета Рединга в Великобритании предсказали, что как минимум треть площади шельфовых ледников в Антарктике могут обрушиться в море. Об этом специалисты сообщили изданию Geophysical Research Letters.

Ученые смоделировали климат в данном регионе и спрогнозировали состояние Антарктики после таяния ледников.

В нынешнем столетии глобальное потепление спровоцирует повышение уровня температуры на полтора-два и четыре градуса Цельсия. Таким образом, шельфовые ледники, которые играют роль так называемой пробки для схода льда с берега в океан, начнут стремительно таять. Это приведет к неминуемой катастрофе.

Каждый год лед с поверхности шельфового ледника тает, стекает в зазоры и опять замерзает. Однако проблема в том, что большое количество талой воды может расколоть ледник, вследствие чего он рухнет в море.

Среди самых «опасных» ледников, которые подвержены таянию в первую очередь, Ларсена С, Шеклтона, Пайн-Айленда и Уилкинса.

Напомним, бразильские ученые зафиксировали в Антарктике рекордно высокую температуру. Впервые в истории белого континента воздух прогрелся там до +18,3°C.
