The Great Barrier Reef Can No Longer Be Saved by Current Efforts, Scientists Warn
The Great Barrier Reef can be saved by plans to protect the existing ecological site, experts have warned, saying efforts should move to a smaller backup plan to maintain the “ecological role” of the reef.
Scientists told an Australian government committee that the current strategy to protect the reef – Coral’s long-term sustainability plan in 2050 – is not feasible in light of recent events of mass whitening, especially in the plan Does not include measures to counteract climate change.
The 2050 US $ 2 billion Plan Reef was launched in March 2015 to enhance the “universal value” of the world’s largest coral reef, each decade prior to 2050.
But at a meeting last week, scientists have warned the advisory committee overseeing the plan by which the goal of improving the reef environment is unrealistic of postal bleaching events in 2016 and 2017, contributing to the worst loss of Record of coral.
Recent figures on coral mortality from recent whitening events are also higher than expected, with new coral reefs expected in 2017, according to Russell Reichelt, president of the Great Barrier Reef Marine Park Authority .
Previously estimated lives of 22 percent of shallow water corals have increased to 29 percent, according to the latest data.
Ahead of this, experts said that revising the plan for a more achievable goal of maintaining ecological function would be more realistic, while accepting the overall health status of reef declines over time, reports Michael Slezak for The Guardian.
“The concept of” maintaining ecological function “refers to the balance of ecological processes required for the reef ecosystem as a whole remains, but perhaps in a different way,” said a spokesman the High Authority of the Marine Park of the Great barrier reef, taking into account the composition and structure may be different to what is currently seen today. ”
This seems rather ambiguous (and fatalistic), but unless further efforts to revise the Coral 2050 plan will be launched soon – including plans to address climate change directly in the strategy, as scientists have urged – this could Be the result we get.
The warnings follow a statement released by the Independent Coral Panel in early 2050, which argued that reducing greenhouse gas emissions should be at the core of protecting the reef, in addition to efforts to strengthen capacity Recovery of coral and reef ecosystems.
“[E] n our lives and our clocks, large areas of the Great Barrier Reef and surrounding ecosystems are significant long-term damage that may be irreversible if no action is taken now,” the panel said.
“The world has changed by what science tells us is unprecedented in the history of mankind. While this in itself may be a cause of action, the extraordinary speed of the changes we observe makes more action Urgent. ”
According to group chairman and former Australian chief scientist Ian Chubb, the 2050 reef plan needs significant overhaul to directly address the elephant in the room: ocean warming, the main contributor washed coral.
“We can not be passive spectators in this area. We are the reef keepers and their ecosystem for the world,” Adam Morton told the Sydney Morning Herald.
“We are not saying that the launch plan and start from scratch – actions on water quality, sediment and fertilizer are still important, but the events we refer to is removed.”
