In this post we find that the 2020 global average surface temperature was 1.25°C hotter than pre-industrial, equal first with 2016, according to The European Copernicus Climate Change Service. This is important for the Great Barrier Reef, because in a little known report in 2013 scientists found that 1.2°C is the warmest compatible with the Reef remaining a coral-dominated system. Focus recently has been on the emergence of annual severe bleaching (ASB) when the affected reefs are effectively dead. Climate change action of the type we are engaged in will only delay the emergence of ASB on average from about 2034 to 2045.Continue reading Temperature pushes Great Barrier Reef to tipping point→
James Cook University has sacked academic Professor Peter Ridd, he claims because he “dared to fight the university and speak the truth about science and the Great Barrier Reef”. He rejects the scientific evidence linking human activity to degradation of the Great Barrier Reef, and takes the view that the Reef is doing fine.
“We defend Peter’s right to make statements in his area of academic expertise and would continue to do that until we are blue in the face,” Gordon says.
“The issue has never been about Peter’s right to make statements – it’s about how he has continually broken a code of conduct that we would expect all our staff to stick to, to create a safe, respectful and professional workplace.”
including $200 million in funding to reduce agricultural pollution and $100 million for “reef restoration and adaptation,” which includes a project to grow stronger corals in laboratories. Other projects include killing off invasive species like the crown-of-thorns starfish and community engagement and enforcement
We plant about 9 billion trees each year. Unfortunately we also clear about 15 billion, leaving a deficit of 6 billion.
A system of using drones is being developed which could plant trees at 10 times the rate of hand planting and at 20 per cent of the cost by firing germinated seeds into the ground. Continue reading Climate clippings 211→
Secondly, Terry Hughes, the lead author of the paper was embarking on aerial surveys to chart the effects of the latest 2017 bleaching event, the first in consecutive years, and the first in a non-El Niño year.
Third, Queensland government officials were in Paris meeting with UNESCO officials to appeal for more time to make good on conservation efforts to ward off an “in-danger” listing for the reef. This conservation plan does not mention global warming, concentrating on such things as water quality.
Our government seems bent on saving the tourist industry by airbrushing the Great Barrier Reef out of UN reports. The report “World Heritage and Tourism in a Changing Climate”, published jointly by UNESCO, the United Nations Environment Program and the Union of Concerned Scientists, initially had a key chapter on the Great Barrier Reef, as well as small sections on Kakadu and the Tasmanian forests.
