Legal protection was inspired by science to help the Great Barrier Reef



One involves the spraying of a biodegradable reflective polymeric calcium carbonate film to reflect the sun's radiation, while others would spill colder water from depths of 10 to 30 meters to mitigate the thermal stress of surface corals.

Funds for feasibility studies of three geoinstruction technologies for ridge protection have been provided: (1) "floating sun shield" from
reflective surface film of calcium carbonate reflecting sunlight and lower water temperature; (2) flooding the sea cloud; and (3) water
mixing.

The third suggestion is that microscopic particles of the salt are pushed into low-sea clouds to increase their reflexivity and reduce the amount of sunlight reaching to the surface of the sea.

"Australia currently does not have a national law or policy that regulates geoengineering or solar radiation management or even how such activities can fit into the national climate response response strategy," the article states.

Jan McDonald, professor of environmental and climatic rights at the University of Tasmania, and chief author of the article, said the "prognosis [for the reef] looks quite grim, "and scientists estimate that most of the world's corals will be lost even if global warming is maintained at the low end of the Paris climate climate of 1.5 to 2 degrees.

As a result, it will inevitably be an attempt at climate action even without avoiding our "serious carbon reduction commitment," said Professor McDonald.

Experience in the UK where a project funded by the government aimed at assessing the feasibility of particle injection into the stratosphere, halted in 2012, indicated that public consultation and transparency were needed at the beginning, # 39; she said. Without this, public confidence in regulators or research would be lost, "probably a dangerous way to descend."

"Australia has the opportunity to do the right thing with the help of the Great Coral Reef, but also to provide a good governance model to other countries that are fighting this issue," said Professor McDonald.

Federal Environment Minister Melissa Price was contacted for comment.

Workplace spokeswoman Tony Burke said, "We are the guardians of the most precious and most endangered resources on the planet.

"If we win in the elections, we will listen to experts about individual projects, as well as the general framework for the protection of the Great Coral Reef."

Green Spokeswoman on the Great Coral Reef Larissa Waters noticed Nature a paper released last week found that 89 percent of new corals did not survive.

"[That] it is clear that renewal and other projects are insufficient – there must be urgent action to address climate change, "said Senator Waters.

"There should be a framework for assessing geoengineering experiments to ensure that no new problems are created."
