Climate change: how Australia's oceans are faring

The CSIRO has released Marine Climate Change Impacts & Adaptation: Report Card Australia 2009.

Based on the science it is stated with confidence that ocean temperatures have become warmer since the first half of the 20th Century and are expected to become even warmer over our lifetime and beyond, there has been a thirty percent increase in hydrogen ion (acid) concentration in sea water over the last 250 years, sea levels rose 20cm between 1870 and 2004 and are expected to keep rising (with every centimetre of rise expected to take one metre of vulnerable land), ocean wave processes are becoming more variable in certain instances, coastal estuary habitat is starting to change and fish population spatial distribution is also altering, first observations of sea birds beginning to react to changes in temperature and food availability, the East Australian Current is becoming stronger while the Leeuwin Current on the other side of the continent appears to be weakening.
Climate change is happening now.
