Scientists come with more alarming news this year. They warn about an imminent and widespread coral reef bleaching in the Great Barrier Reef.
The Great Barrier Reef Marine Park Authority performed surveys and found that the reefs showed a high risk of bleaching. Apart from their own surveys, they received reports that stated bleaching from scientists, marine park rangers, tourism operators, and even community members.
The massive bleaching of coral reefs around Australia was caused by a heatwave that caused wildfire and incredibly high temperatures. Alarmingly high numbers of corals were killed by the extreme heat last year.
Also, the satellites of thermal imaging showed that waters in the area had again unusually high temperatures, which raised the concern of imminent bleaching.
Last month, the environmental ministry in Japan reported the largest coral reef bleaching that had ever occurred in their country. The reports showed that over 70 percent of the coral reefs in the area around Japan was killed after sea temperatures were one or even two degrees Celsius higher than they should have been.
Since the trend in the rise of sea temperature is so widespread and their effects are so devastating to coral reefs, the scientists predicted a new massive process of bleaching for the fourth year in a row.
Scientists and environment officials are trying to take measures against sea surface temperature rise, but are they enough to stop coral bleaching? They have warned that the current targets that aim to reduce greenhouse gas emissions are not enough to prevent the massive loss of coral and they will render bleaching inevitable.
The reports conducted by the scientists show that drastic measures should be taken immediately against climate change all around the globe or massive coral death will keep occurring.
After all, what is in fact coral bleaching? This process occurs when corals expel algae that perform photosynthesis. This is usually caused by water temperatures higher than normal and makes the corals lose their color and eventually die.
The Australian Marine Conservation Society is trying to notify the government to take quick action against new coal mines that are set to run soon. These mines would only make the bleaching worse. If they fail to control these activities, the future is not so bright for the coral reefs and the next four weeks are predicted to bring high rates of coral bleaching and deaths.
