Climate change plays ‘Russian roulette’ with the world’s oceans

The world’s oceans will see dramatic changes thanks to climate change, affecting hundreds of millions of people who depend on the sea according to research published today in the online journal PLOS Biology…

Global warming’s evil twin: ocean acidification

Greenhouse gas emissions have warmed the oceans in regions such as the Baltic by as much as 1.3°C. It is now thought that 90% of the heat added to the climate system by humans has been absorbed in the…
Fish, corals and molluscs are all affected by a more acid ocean. Tony Shih

Change the fundamentals and you are in an ocean of trouble

Recent studies have shown several marine species are struggling to adapt to the excess carbon dioxide and heat which oceans are absorbing. Evidence is mounting of the risks we’re taking with our oceans…

Ocean acidification is chemistry, not conjecture

As a scientist working on the impact of climate change on marine ecosystems, one of my duties is to communicate my work. My main goal is to convince students, citizens, economists and politicians that…

Test tube reveals coral’s secrets

Scientists have used test tubes to discover coral’s secret to building their external skeletons. The Rutgers Institute study…

Sea urchins rolling with the punches

Purple sea urchins have been found to be able to evolve extremely rapidly in relation to their environment. Experiments conducted…

Warning bells: what Antarctica can teach us about ocean acidification

When it comes to climate change, temperature is only part of the story. Climate gases released by human activity are dissolving into the oceans, and the increased levels of CO₂ are making the waters more…
Recent research shows an acidifying ocean is more damaging to coral than we’d hoped. Community Eye Health

Jumps in ocean acidity put coral in more peril

Ocean acidification - where the ocean becomes less alkaline as it absorbs excess CO2 from the atmosphere - has been described as the evil twin of global warming. Yet, remarkably, it is only over the past…

Life of Pi’s acidic island a warning for our warming world

The recently released film Life of Pi directed by Ang Lee and based on Yann Martel’s novel of the same name, is a fable for our climate change times. Much of the plot involves the struggles of a teenage…
Everyone wants good news about coral, but we shouldn’t misinterpret the latest findings. Phil Camill

Research good news for coralline algae, but not necessarily for reefs

As Doha disappoints on delivering any real progress on reducing global CO2 emissions, new research demonstrates that a key component of coral reef structures may be more resilient in the face of increasing…

Ocean winners and losers revealed in Marine Report Card

Fish are on the move in Australia’s waters. In southern Australia, scientists, commercial and recreational fishers, divers and beach-goers are reporting the presence of new species. The movement of species…
There will be “winners and losers in the oceans” as its chemistry changes. AAP

Some corals could survive a more acidic ocean

Internal “pumps” found in some corals may help them to endure gradual ocean acidification, giving rise to hope that coral reefs might escape climatic devastation, according to new research. A team of scientists…
