A strong low pressure system brought raging southerly winds, which have caused extensive beach erosion. I took this image the day that it all began to settle down, but the waves were still large (and the water very dirty from river run-off).

Over recent weeks there's been severe weather in eastern Australia. My area has been fortunate to have been spared the ongoing record floods affecting places further up the coast, but an unusual weather pattern did bring gale force winds which have resulted in major beach erosion. In one area the breaking waves crossed the beachfront (see PiP1), passed under the trees, across the road behind and almost to the houses in the background. The following day I took the image (in PiP 2) of the reducing but still significant waves. At Andy's request, the PiPs are now viewable as separate images. This seems very appropriate with the release in the past few days of the 3rd part of the report of the expert Intergovernmental Panel on Climate Change. The IPCC report stresses the need for urgent action to limit emissions and minimise the effects of climate change which include extreme weather.

Significant erosion at part of the beach, as a result of an intense low pressure system that brought high winds and giant surf. Hopefully the well established Norfolk Island Pines will not be affected by their exposure to salt water, as a result of waves running past them at the height of the storm

The dunes at our local beach are gradually but steadily being eroded. This is entirely consistent with what is expected due to rising sea levels associated with climate change. The causes are melting ice from glaciers and ice caps, plus expansion of the ocean water as its temperature rises. As explained in this link, ocean levels have risen by about 25cm since 1880 and the rate has increased to about 3cm a decade now. No wonder the people on low-lying islands are concerned!
