The reverse was true on the other side of the Pacific, around 13,000 kilometres away. From California down through Mexico to Chile and Peru, we saw beaches narrow during El Niño periods and widen out again during La Niña periods.
Why? Storms and sea levels. During El Niño events, large storms develop in the northern Pacific, sending energetic waves crashing onto the coastlines of California and Mexico — creating the perfect conditions for big wave surfing. During this period, the sea level is well above average too. Combined, bigger waves, storms and a higher baseline pillage sandy beaches. This is particularly pronounced in the eastern Pacific.
With tools like these, we can monitor coastal changes across thousands of beaches over the last 40 years.

ABC did a great job of triggering the cookers with this post
74 has the highest hide tide mark in Sydney Harbour on record, which was also in the middle of a Triple La Niña.
It was more than 'beaches' that disappeared off Collaroy - it was back yards built on sand dunes where the State govt overruled Council opposition to building on sand.
Yeah there's lots of weather effects around the globe, La Nina, El Nino and even El Toro not sure what he does
So NOTHING to do with so called man made global warming?
OH you mean nature?

Current NASA Sat data shows temps currently under 1998 and below the 30year average... Yes lefties, It's still warmer than '79 when global cooling was a thing. Take a chill pill.
Rapid sea-level rise cause CC must one of ABC's biggest lies ever 😅, ABC should be totally humiliated & embarrassed, if they did these things sad
They're not going to recover from climate change induced sea level rise. ClimateActionNow
