Beachgoers glimpse what coastlines would look like 50 years hence

Sydney, Jan 13 (IANS) Beachgoers at New South Wales and South East Queensland experienced huge ‘king tides’ - a glimpse of what coastlines would look like in the next 50 years. “By 2060 to 2070 we could be experiencing tides of at least this magnitude every month, rather than just twice a year due to climate-change induced sea level rise,” said Kathy McInnes, research scientist with CSIRO’s Climate Adaptation National Research Flagship.

King tides are natural events that happen twice a year. McInnes said observing the king tide can assist communities to plan and prepare for the effects of climate change, according to a CSIRO release.

“This king tide can help us picture what our coastlines might look like in the future.”

According to the Intergovernmental Panel on Climate Change, sea levels are projected to rise by between 18-79 cm or more this century.

“Photographing or recording the effect of the king tide on seawalls, jetties, coastal infrastructure and foreshore areas creates a helpful visual record for use in adaptation planning,” McInnes said.

Scientists from the CSIRO Climate Adaptation Flagship are working with communities, governments and industry to understand and prepare for the impacts of climate change.
