New wave of coral bleaching raises concerns for Great Barrier Reef

Given the Greenie lies about the last bleaching  -- Peter Ridd won a court case over his criticisms of them --  this report is fit only to be ignored

Perhaps the most amusing part of the previous scare was when the Federal minister visited the reef to see for herself how bad it was.  She found it looked fine.  We read:  "The Great Barrier Reef Marine Park Authority has supported Environment Minister Sussan Ley's appraisal that the reef is "good" and has "a vibrant future"."

They completely walked back their cries of doom.  I guess not all Greenies are crooks but most of them seem to be


Another wave of coral bleaching is hitting the Great Barrier Reef as temperature levels surge above average.

The federal government’s lead reef protection agency on Wednesday discovered significant bleaching on three reefs in the far north of the world’s largest coral reef ecosystem.

“That is the first time we’ve seen significant bleaching so far this summer,” said David Wachenfeld, chief scientist with the Great Barrier Reef Marine Park Authority.

“It is a confirmation of our growing concern about what is happening out on the reef at the moment.” Heat stress that has built up on the far northern, central and southern parts of the reef over the summer has intensified over the last week. “These levels of heat stress are definitely capable of causing coral bleaching and we are now at a heightened level of alertness for what is happening out there in the park,” Dr Wachenfeld said.

A bleaching warning has been issued for large parts of the Torres Strait and far northern management areas of the marine park, where significant bleaching across multiple hot spots is likely.

Most of the area covered by the marine park was 0.5 to 1.5C above average as of February 11, with some central and southern parts being 2 to 3C warmer. “February is the hottest month of the year on the reef so these anomalies are really very concerning,” Dr Wachenfeld said.

The reef authority has been told of bleaching in other areas and is sending staff to survey the damage.

Further heat stress is expected over the next few weeks as temperatures remain high.
