'Zero recovery' for corals in back-to-back Australia bleaching
April 10, 2017

Australia's Great Barrier Reef is suffering a fourth round of coral bleaching this year, after being hit in 1998, 2002 and 2016

Coral bleached for two consecutive years at Australia's Great Barrier Reef has "zero prospect" of recovery, scientists warned Monday, as they confirmed the site has again been hit by warming sea temperatures.

Researchers said last month they were detecting another round of mass bleaching this year after a severe event in 2016, and their fears were confirmed after aerial surveys of the entire 2,300-kilometre (1,400-mile) long bio-diverse reef.

Last year, the northern areas of the World Heritage-listed area were hardest hit, with the middle-third now experiencing the worst effects.

"Bleached corals are not necessarily dead corals, but in the severe central region we anticipate high levels of coral loss," said James Kerry, a marine biologist at James Cook University who led the aerial surveys.

And too many people don't care. They don't understand our impact on the seas, and they don't understand the potential issues that go with it.

If the chances of recovery is zero ... why worry about it?

Don't the fucking liberals still travel in big SUVs and jet aeroplanes? Get back to us when they don't.

Don't the fucking liberals still travel in big SUVs and jet aeroplanes? Get back to us when they don't.

Before I entered pre-school, my mother taught me not to use the behavior of other people to excuse my own.

You apparently never learned that lesson. Most conservatives didn't. Their morality literally doesn't even reach pre-schooler level.

3-year Global Coral Bleaching Event Easing, But Still Bad
June 19, 2017 | WASHINGTON — A mass bleaching of coral reefs worldwide is finally easing after three years, U.S. scientists announced Monday.

About three-quarters of the world's delicate coral reefs were damaged or killed by hot water in what scientists say was the largest coral catastrophe. The National Oceanic and Atmospheric Administration announced a global bleaching event in May 2014. It was worse than previous global bleaching events in 1998 and 2010.

The forecast damage doesn't look widespread in the Indian Ocean, so the event loses its global scope. Bleaching will still be bad in the Caribbean and Pacific, but it'll be less severe than recent years, said NOAA coral reef watch coordinator C. Mark Eakin. Places like Australia's Great Barrier Reef, northwest Hawaii, Guam and parts of the Caribbean have been hit with back-to-back-to-back destruction, Eakin said.

University of Victoria, British Columbia, coral reef scientist Julia Baum plans to travel to Christmas Island in the Pacific where the coral reefs have looked like ghost towns in recent years. “This is really good news,” Baum said. “We've been totally focused on coming out of the carnage of the 2015-2016 El Nino.” While conditions are improving, it's too early to celebrate, said Eakin, adding that the world may be at a new normal where reefs are barely able to survive during good conditions.

Eakin said coral have difficulty surviving water already getting warmer by man-made climate change. Extra heating of the water from a natural El Nino nudges coral conditions over the edge. About one billion people use coral reefs for fisheries or tourism. Scientists have said that coral reefs are one of the first and most prominent indicators of global warming. “I don't see how they can take one more hit at this point,” Baum said. “They need a reprieve.”
