The twin stress factors of ocean warming and acidification increasingly threaten coral reefs worldwide, but relatively little is known about how various climate scenarios will affect coral reef growth rates. Our research, published today, paints a grim picture. We estimate that even under the most optimistic emissions scenarios, we’ll see dramatic reductions in coral reef growth globally. The good news is that 63% of all reefs in this emissions scenario will still be able to grow by 2100. But if emissions continue to rise unabated, we predict 94% of coral reefs globally will be eroding by...

Share When Dr Christopher Cornwall began his biological research career, three unanswered questions bothered him about how climate change might affect marine organisms. The Te Herenga Waka—Victoria University of Wellington Rutherford Discovery Fellow has now won this year’s Prime Minister’s MacDiarmid Emerging Scientist Prize for helping answer them. Dr Cornwall, in the School of Biological Sciences, becomes the third Te Herenga Waka researcher to win the $200,000 award. His success follows the awarding last year of the top Prime Minister’s Science Prize to a team from the Universit...

Another household name, University of Otago epidemiologist Michael Baker, won the Prime Minister's Science Communication Prize. Otago University said in a statement Prof Baker had been New Zealand's go-to science professional since the start of the pandemic. "Prof Baker wrote the book on New Zealand's hugely successful COVID-19 elimination strategy, using multiple forms of science communication to actively promote a move away from a mitigation strategy in early March 2020." Prof Baker said he was relieved when the Government implemented the COVID-19 elimination strategy. "I felt absolutely co...

The increased temperatures, caused by our use of fossil fuels, are also a problem. Marine heatwaves stress out species such as coral and kelp. During these events, marine life can die in a matter of weeks, and it can take up to a decade for the ecosystem to recover, Cornwall said, if it recovers at all. Although these events are depressingly frequent in Australia, they’re also occurring here as well. “I like to think of Australia as a canary in a coal mine,” he added.
