Explorers are set to deliver the first live video broadcast from deep below an ocean's surface. Early next week, a submersible is expected to dive to 300 meters (nearly 1,000 feet) off the Seychelles in the Indian Ocean and send images to a satellite transmitter on the mother ship. The Associated Press will send that footage around the world. The British-led Nekton Mission highlights the state of the oceans as fears grow over climate change. The Indian Ocean is the least explored in the world, and there is almost no data from the Seychelles below scuba depth. That's about to change.

We've gone from white to blue," said a former NASA scientist, adding that he normally wouldn't use the word "scary" but it applies.

A third of Guam's coral reefs have died because of rising ocean temperatures, researchers said. University of Guam researchers said increased temperatures killed 34% of Guam's coral reefs between 2013 and 2017. About 60% of the reefs along Guam's eastern coast are gone, scientists said.

Greta Thunberg's two-week voyage to the United States will be no pleasure cruise. The 16-year-old climate change activist who has inspired student protests around the world will leave Plymouth, England, bound for New York in a high-tech but decidedly low-comfort sailboat.

Hundreds of U.S. states, cities, businesses and churches planted the American flag at the U.N. climate talks Friday in an effort to show that many people in the United States remain committed to curbing global warming despite the stance of their president.
