Extreme measures to save corals at GBR

by TNP Editor 2021-4-30

SCIROUsing “cloud brightening” technology, controlling the spread of a predator starfish, and introducing heat-tolerant corals, scientists at CSIRO, Australia’s national science agency, hope to slow the demise of corals at Australia’s Great Barrier Reef (GBR).

The cloud brightening technology is experimental; it is based on spraying salt crystals into the air above the GBR, making clouds more reflective of sunlight and thus cooling waters around the reef.

Likewise, by introducing different corals, scientists hope to maintain coral coverage with more hardy and heat-tolerant species.

The simulation work done by CSIRO suggests a reprieve of up to 20 years based on these combined interventions. A key assumption of the model is that global temperatures will not rise beyond 1.8 degrees Celsius by the year 2100, and the emission of greenhouse gases and other climate factors will need to be addressed.

14th International Coral Reef Symposium at Bremen – registration now open

by TNP Editor 2021-4-27

The 14th International Coral Reef Symposium (ICRS) 2021 will be held at Bremen, Germany this summer on July 19-23.

14thICRS

This symposium is a great opportunity for marine biologists, policy experts, scholars and students to present their research findings, policy and scientific papers, as well as student posters. This is a premier event for the global scientific community to promote reef conservation and advance their research and professional development.

This will be the first VIRTUAL event in the 50+ year history of the ICRS. All presentations will be archived so that attendees can view them afterwards. Thus, attendees will not miss any oral or poster presentations at the 14th ICRS 2021 VIRTUAL when compared to prior ICRS and other large international conferences where many concurrent sessions were running at the same time.

Registration is now open. Click here to register.
