Moreton Bay seagrass projected to drastically decline with sea level rise

Submitted by takver on Sat, 18/05/2013 - 11:02pm

To most of us, what is hidden beneath the waves of our coastal environment remains invisible and is little thought about or cared about. Yet seagrass meadows, though hidden from our direct view, contribute valuable ecological services supporting valuable fish nurseries, as food for dugongs and turtles, and as a highly efficient blue carbon sink sequestering carbon.

A new study of the seagrass meadows in Moreton Bay, Queensland found that a significant proportion of valuable seagrass habitats would be lost without action to offset the affects of climate change. "The area of seagrass habitat was predicted to decline by 17% by 2100 under a scenario of SLR of 1.1 m." said the study.

Planners need to allow for Coastal wetlands migration due to sea level rise, climate change

Submitted by takver on Sat, 19/01/2013 - 5:28pm

Coastal Wetlands are under pressure. They face rising seas from climate change, but their biggest obstacle to migrate naturally inland is human development with roads, houses and other infrastructure blocking their way. And our urban planners are largely unaware of this tricky situation.

Climate change, sea level rise and Australia

Submitted by takver on Tue, 04/10/2011 - 12:33am

Average global sea level is rising at the fastest rate in 2000 years according to scientists, and north and western Australia is copping more than double the global average in sea level rise. The rate of increase has accelerated in the last 20 years which has been attributed by scientists to thermal expansion, small glacier melt and accelerating ice sheet loss from the Greenland and West Antarctic ice caps caused by climate change and global warming. A peer reviewed scientific study published in June 2011 from the Potsdam Institute for Climate Impact Research has shown the rate of Sea level rise is connected to global temperature rise.

Scientists affirm Australia's climate already changing

Submitted by takver on Tue, 16/03/2010 - 3:43am

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.

Walkers mark the dangers of rising sea level for Melbourne

Submitted by takver on Sat, 21/11/2009 - 10:17pm

Community and environment groups today started a 100km walk from Sorrento to Port Melbourne around Port Phillip Bay, to raise awareness about climate change and rising sea levels in Victoria and around the world. Markers were placed along the way to show where the sea level will rise to by the end of the century if efforts to reduce greenhouse gas pollution do not happen immediately.

Report assesses climate risks of sea level rise for Australia

Submitted by takver on Sun, 15/11/2009 - 1:11am

A new report published by the Australian Government - Climate Change Risks to Australia's Coasts povides a risk assessment of climate change and rising sea level to Austrlian coastal communities. The report shows between 157,000 to 247,600 existing residential buildings will be at risk from sea inundation by 2100, under a sea-level rise scenario of 1.1 metres.
