Ocean biodiversity may collapse within the next decade

By 2030, tropical oceans may lose much of their biodiversity, according to an international team of researchers. Some areas of the globe are more affected than others by global warming.

Global warming is a real threat to our planet and, if greenhouse gas emissions do not go down, we will lose a lot of biodiversity in the coming years. New research shows that tropical oceans may collapse within the next decade.

Some regions are more affected than others due to a variety of factors. According to Science Alert, scientists estimate that taking into account current emissions, the temperature on Earth could rise 4ºC by 2100.

A team of researchers analyzed more than 150 years of climatic data and crossed information with the spread of more than 30 thousand species of birds, mammals, reptiles and fish. The results of the study were published last week in the scientific journal Nature.

In the current situation, experts predict the warming of the oceans will affect up to 73% of the species, which will suffer from potentially disastrous effects on their populations.

Alex Pigot, the co-author of the study, suggests that animal populations may experience collapse if a temperature limit is exceeded. “As we pass this threshold, we expect the risk of local extinction to increase substantially,” Pigot told AFP.

However, it all depends on greenhouse gas emissions. If the levels proposed in the Paris Agreement are reached, “only” 2% of animals will face extreme heat that can cause “irreversible damage”.

In the case of tropical oceans, the situation may start to deteriorate as early as this decade. Recent events, such as the mass bleaching of the Great Barrier Reef, suggest that this is already occurring in some locations.
