Walter Munk might be the most under-appreciated man in surfing, but he is a big deal in ocean science. If you've ever checked a surf forecast before paddling out, you have him to thank.
The same beach on Henderson Island, in 1992 and 2015.
After making worldwide headlines with the story of the Pacific "garbage island", researchers were sent a photo of the same beach, white sand free of litter, as recently as 1992.
The tropical Pacific has a large say in how fast the world warms.
If the Pacific Ocean enters an 'El Tio' phase, it could speed the world towards 1.5 degrees of global warming, one of the crucial benchmarks of the Paris Climate Agreement.
Cyclone Debbie looms over Queensland on Monday afternoon March 27.
The category 4 cyclone - the fifth storm of this year's season, and the strongest so far - has buffeted the Queensland coast across a wide area centred on Airlie Beach.

Since 1999, Australia has swung between drought and deluge with surprising speed, because El Niño has fallen into sync with similar patterns in the Indian and Southern Oceans.
The site of the hillfort of Vugala, northern Viti Levu island (Fiji). This was one of many hillforts in the area – home to a few hundred people according to reports from the 1840s – that were probably established around AD 1400 in response to conflict resulting from a food crisis that had come about as a result of an enduring fall in sea level.
Rising seas are one of the major concerns of Pacific Island nations, and looking at past sea-level change can help understand the future.

Corals are experiencing only the third global bleaching event in recorded history, caused by warming seas. But worse is yet to come.
El Nino brings drought to Indonesia, and warmer weather to almost the entire globe.
El Niño has a hugely pervasive effect on global temperatures - for every degree the tropical Pacific warms, land temperatures warm by 1.5 degrees. How? Because the tropical ocean is a very good heater.
More frequent disasters – such as Cyclone Pam which struck Vanuatu this year – will leave Pacific islands struggling to recover.
As Prime Minister Tony Abbott attends the Pacific Island Forum summit today, attention has again turned to how the low-lying islands will deal with global warming.
