Experiment shows coral reefs in peril in a high CO2 climate change world

Professor Ove Hoegh-Guldberg takes us through and explains a controlled experiment his Institute is conducting in coral reef ecosystem reaction to various temperature and carbon dioxide environments. He argues that Coral Reef ecosystems have already changed significantly from pre-industrial times, and will change even further as human carbon emissions increase in the atmosphere with many species likely to be pushed to extinction due to heat stress and ocean acidification from anthropogenic climate change.

Hoegh-Guldberg is Director of the Global Change Institute at the University of Queensland and an important authority on tropical marine biology, coral reef ecosystems and climate change.

Oceans at high risk of unprecedented Marine extinction scientists warn

A report issued last week from the International Programme on the State of the Ocean (IPSO) has strongly warned of the damage to the health of the world's oceans and marine life from several factors including the impacts of climate change. The report warned that if the current business as usual trajectory of damage continues "that the world's ocean is at high risk of entering a phase of extinction of marine species unprecedented in human history."

Scientists affirm Australia's climate already changing

In a joint statement released on Monday by the CSIRO and Bureau of Meteorology the stark facts on global warming were outlined: that Australia's climate has already changed with more extremely hot days, fewer cold ones, wetter in the north and drier in the south-east and south-west. The statement outlined in five sections a snapshot of temperature, rainfall, oceans, atmosphere, and what this means for Australia in coming decades.
