Australia UNESCO Barrier Reef report says 'outstanding values' have worsened
In New York lab, centuries-old corals hold clues to climate shifts
In New York lab, centuries-old corals hold clues to climate shiftsPALISADES, N.Y. (Reuters) - Some 20 miles north of New York City, a team of scientists is searching for clues about how the environment is changing by studying organisms not usually found in the woods around here: corals.
Coral bleaching, a series of cyclones and crown-of-thorns starfish have worsened the "outstanding universal values" of the Great Barrier Reef, a federal government report prepared for UNESCO has found.
The 348,000-square-kilometre reef off the Queensland coast has been a UNESCO World Heritage Listed site since 1981.
It is a multibillion-dollar tourism drawcard that generates about 64,000 jobs in tourism and tourism-related industries.
Whale shark expedition on Great Barrier Reef uncovers great mysteries of world's largest fish
The whale shark may be the world's largest fish but locating them on the Great Barrier Reef is like "finding a needle in a haystack".Unlike Western Australia's Ningaloo Marine Park — a known aggregation site the species frequents — sightings off the east coast are sporadic.
In 2020, UNESCO will decide if the decline in those "outstanding universal values" warrants listing the site as "in danger", meaning it could lose its status.
On Monday, the federal government's State Party Report to UNESCO's world heritage committee made three significant findings on Australia's progress since 2015 to protect the Great Barrier Reef.
First, it found mass coral bleaching events in 2016 and 2017, six tropical cyclones, flooding and a coral-eating crown-of-thorns starfish outbreak had "impacted the outstanding universal values" of the reef.
Second, it reported the Great Barrier Reef Marine Park Authority had found the long-term outlook for the reef’s ecosystem had "deteriorated from poor to very poor", as previously reported.
Sydney and Melbourne house values surge on lower interest rates
The biggest jump in Sydney house values since 1988 help propel national market through November.CoreLogic's monthly measure of values showed dwelling values across the nation's capitals jumped by 1.7 per cent in November, the biggest monthly lift since 2003.
It also found climate change, especially the rise in sea temperature, remained the most serious and pervasive threat to the Great Barrier Reef.
The report traced policy initiatives under the federal government's Reef 2050 Long-Term Sustainability Plan and acknowledged it was crucial to keep atmospheric temperature increases to 1.5 degrees.
"Concerted global action to limit global warming is needed to turn around the deteriorating outlook for the Great Barrier Reef – and all other coral reefs," the report said.
"We are actively managing the pressures over which we have direct control through investment and regulation based on the best available science."
The report met with a muted response from the Greens and conservation groups.
Greens deputy leader Larissa Waters described the report as "an exercise in spin" and said not enough action was being taken in Australia to reduce climate change.
Bob Irwin comes clean on the family feud that's left him estranged from grandkids Robert and Bindi - and says he hasn't heard from her since her engagement
Bob Irwin has not received a response since writing a letter to his grandchild wishing her will after she announced that she was engaged to fiance Chandler Powell, 22, in July this year. He told Courier Mail it stemmed from a misunderstanding after a reporter walked onto his property hoping to get a few comments on what he thought about the engagement.When Mr Irwin refused to answer it was mistakenly taken as a begrudged silence - photos of him at his home were also splashed in the tabloid only fuelling the false impression he was unhappy with the planned marriage.
“The World Heritage Committee gave Australia homework four years ago, to show why the reef shouldn’t be listed as 'in danger'," she said.
“In that time, half the coral cover of the reef has bleached to death and its outlook has been downgraded to 'very poor', while the federal government has refused to address climate change and has questioned reef water science. They have failed their homework."
Australian Marine Conservation Society director of strategy Imogen Zethoven said Australia needed to encourage other nations to reduce emissions to mitigate atmospheric temperature increases.
"It is in Australia’s interest to play a leading role in getting the world to act, and the only way it can do that is by acting at home while urging other countries to follow our example," Ms Zethoven said.
"The report states that 1.5 degrees is widely cited as a critical threshold for the reef, but it doesn’t commit Australia to do our fair share of global emissions reduction to limit temperature rise to 1.5 degrees centigrade."
