The hunting ability and growth of sharks will be dramatically impacted by increased CO2 levels and warmer oceans expected by the end of the century, a University of Adelaide study has found.
Published today in the journal Scientific Reports, marine ecologists from the University of Adelaide’s Environment Institute report long-term experiments that show warmer waters and ocean acidification will have major detrimental effects on sharks’ ability to meet their energy demands, with the effects likely to cascade through entire ecosystems.
Did you know that electricity is the biggest single source of carbon emissions in Britain? The absorption of carbon dioxide emissions by the ocean has a direct impact on marine ecosystems. The good news is reducing our carbon footprint can be as easy as making the switch to renewable energy.
The decline of Caribbean coral reefs has been linked to the recent effects of human-induced climate change. However, new research led by scientists at Scripps Institution of Oceanography at UC San Diego suggests an even earlier cause. The bad news – humans are still to blame. MORE
Oceans Day 2011 addressed several issues related to marine biodiversity, including the ecosystem approach, payment for ecosystem services (PES), invasive marine species, ocean acidification, coral bleaching and fish stocks depletion.
Large scale "geoengineering" solutions to climate change will not reverse rising acidity in the oceans which damages marine life, conservationists have warned.
The International Union for Conservation of Nature (IUCN) issued a call at the UN climate talks in Durban for countries to urgently address the issue of ocean acidification, caused by greater levels of carbon dioxide in the atmosphere.
