Large-scale coral bleaching observed again on Great Barrier Reef in rare anti-Christian year

The adverse effects of global warming and climate change on the environment continue. Even though this year is an anti-El Niño year with cooler sea temperatures, Australian government officials have confirmed that Australia’s Great Barrier Reef is facing another large-scale coral bleaching event; there is also a large iceberg in Antarctica. Shelf collapsed.

The Great Barrier Reef is the largest and longest coral reef group in the world, covering an area of ​​345,000 square kilometers and home to more than 1,600 species of fish and more than 600 types of coral, but due to climate change, over-tourism and other reasons, the condition of the Great Barrier Reef is deteriorating, and the coral bleaching crisis is increasing day by day. Serious day.

Rising sea temperatures have led to large-scale coral bleaching, and this is the fourth time in six years that the Great Barrier Reef Marine Park Authority has observed such severe and large-scale bleaching. Scientists believe that if the world’s largest coral reef system is to be protected, Action on climate change is needed as soon as possible.

What is worrying is that this year is still the anti-elius phenomenon, that is, the sea level in the eastern and central Pacific Ocean is colder than usual, which means that even though the sea temperature is relatively cold, coral reefs are still bleached. What degree of damage will be caused to corals in the year of the Holy Child, when the temperature is abnormally warmed?

The Great Barrier Reef Marine Park Authority has warned that water temperatures on some reefs are 4 degrees warmer than the March average, and weather in the coming weeks will also affect the severity of bleaching.

The Australian Conservation Foundation said it was heartbreaking to see mass coral bleaching again, and the ongoing bleaching events have hit tourism hard, as well as everyone who loves the natural wonders of the Great Barrier Reef.

For the record, scientists first observed mass bleaching of corals on the Great Barrier Reef in 1998 and have since become more frequent, with observations in 2002, 2016, 2017 and 2020.

On the other hand, hot weather is also affecting the Antarctic below Australia. Satellite imagery shows another massive ice shelf collapsed in Antarctica after a record-breaking heat of 40 degrees higher than usual.

The US National Ice Center said on March 17 that the Concordia Research Station, just a few thousand kilometers from the South Pole, observed a record high of -11.8 degrees Celsius, iceberg C-38 Conger (Conger) Ice The rack is detached from Wilkes Land. It is reported that the area of ​​the Conger Ice Shelf is about 1,200 square kilometers, which is the size of Los Angeles.
