NORWAY: The world’s oceans are under greater threat than previously believed from a “deadly trio” of global warming, declining oxygen levels and acidification, an international study said on Thursday.
The oceans have continued to warm, pushing many commercial fish stocks towards the poles and raising the risk of extinction for some marine species, despite a slower pace of temperature rises in the atmosphere this century, it said.
“Risk to the ocean and the ecosystems it supports have been significantly underestimated, “according to the International Programme on the State of the Ocean (IPSO), a non-governmental group of leading scientists.
“The scale and rate of the present day carbon perturbation, and resulting ocean acidification, is unprecedented in Earth’s known history,” according to the report, made with the International Union for Conservation of Nature.
The oceans are warming because of the heat from a build-up of greenhouse gases in the atmosphere. Fertilizers and sewage that wash into the oceans can cause blooms of algae that reduce oxygen levels in the waters. And carbon dioxide in the air can form a weak acid when it reacts with sea water – R.
What is the topic of the text?
The greenhouse effects
The deadly trio of threats to the world
The global warming and marine species
The worst condition of the world's oceans
The threat of global warming to the world's ocean
Berdasarkan informasi ‘The world’s oceans are under greater threat than previously believed from a “deadly trio' of global warming’ yang ditemukan dalam paragraf pertama, dapat diketahui bahwa ada tiga ancaman global warming pada lautan di planet bumi, yakni pemanasan global, penurunan tingkat oksigen, dan pengasaman sehingga pilihan jawaban (E) adalah yang paling tepat.
