In 2017, Hawai‘i set high tide records for four straight months. It turned out to be because of a combination of factors including sea level rise, and an El Nino effect. Today, HPR’s Planet808 takes a look at the high tides we’ll be experiencing this week.

Some very high tides are expected later this month, Nov. 25 to Nov. 28. Hawai‘i’s last "king tide" event happened at the end of July. Combined with a freak south swell, ocean levels rose over three feet and reached their highest point of the year so far. One water expert explains how Honolulu will cope with rising sea levels.

A hardy band of UH faculty and state and county officials is just back from a learning trip to U.S. East Coast cities that are wrestling with climate change. This week’s Future Focus conference brought academic, business, and government leaders together to collaborate on climate adaptation.

In 2012, the city of Hoboken, New Jersey experienced flooding in excess of 9 feet above normal levels. The city of 50,000 people, which sits just across the Hudson River from Manhattan, had sustained a nearly direct hit from a Category 3 hurricane. One source of flooding was a long-forgotten river, which had been paved over decades earlier.

A national scientific report on Climate Change released over the Thanksgiving holiday has underscored what communities across the nation need to do to adapt to global warming. Honolulu Mayor Kirk Caldwell said that both the urban core will need to adapt and more rural communities may need to move.

Research published this week shows that sea levels will rise at least three feet by the year 2300, and that’s a best case scenario. Rising waters already threaten low-lying island nations in the Pacific and will eventually trigger mass migration. We have more from Neal Conan in today’s Pacific News Minute.

Severe weather is dominating national headlines—from Hurricane Irma’s move toward Florida to the aftermath of Hurricane Harvey. It’s also bringing closer attention to the potential effects of climate change. And a new report from the World Bank highlights particular risks in the Asia Pacific. HPR’s Bill Dorman has more in today’s Asia Minute.

Today on Bytemarks Café, we’ll explore the rising tides, climate change and a phenomenon called King Tides. We’ve seen the physical effects of the recent King Tides but what can citizens do to help researchers studying potential.

Scientists studying sea level rise at the University of Hawaiʻi at Mānoa need your help. Impacts of some of our highest tides of the year are predicted to be seen this week. And the general public is being summoned to document those impacts along the thousand or more miles of coastline across the island chain. HPR reporter Kuʻuwehi Hiraishi explains how anyone with a smartphone and coastline access can contribute to science.
