In this Thursday, Aug. 1, 2019, photo, evidence of a Cascadia earthquake's awesome destructive power is visible at the beach in Neskowin, Ore. A "ghost forest" of Sitka spruces juts up from the beach in the tiny town. The trees were likely buried by tsunami debris 2,000 years earlier, and partially uncovered by storms in 1997.

FILE - In this June 13, 2012, file photo, Asian carp, jolted by an electric current from a research boat, jump from the Illinois River near Havana, Ill. A newly released study says if Asian carp reach Lake Michigan, they probably would find enough food to spread far and wide. Some experts have questioned whether there’s enough plankton in the lake to sustain the invasive carp away from shoreline areas. But the new report released Monday, Aug. 12, 2019, by University of Michigan scientists says despite a drop-off of plankton caused by exotic mussels, the voracious carp could feed on other organic material when venturing into deeper waters.

FILE - In this Oct. 5, 2017, file photo, residents move a "no wake," sign through flood waters caused by king tides in Fort Lauderdale, Fla. Federal scientists, according to a report released Wednesday, July 10, 2019, predict 40 places in the U.S. will experience higher than normal rates of so-called sunny day flooding this year due to rising sea levels and an abnormal El Nino weather system.

In this undated handout photo provided by the Pelagos Cetacean Research Institute on Friday, June 21, 2019, researchers Alexandros Frantzis and Voula Alexiadou lie on a tennis court next to the plastic that was in the stomach of a dead sperm whale found on the Aegean Sea island of Mykonos. The collection includes a Greek souvlaki restaurant bag, Turkish trash bags and biscuit packaging. A study of whales and dolphins that have washed up dead in Greece over a 20-year period has found alarmingly high levels of plastic trash - mostly bags - in the animals' stomachs, which can condemn them to a slow and painful death.

FILE - In this Wednesday, July 8, 2015 file photo, herring are unloaded from a fishing boat in Rockland, Maine. A study published Tuesday, June 11, 2019 finds a warmer world may lose a billion tons of fish and other marine life by the end of the century. The international study used computer models to project that for every degree Celsius the world warms, the total weight of life in the oceans drop by 5%. (AP Photo/Robert F. Bukaty, File)

In this May 24, 2019 photo, teachers and students from Northwest Montessori School in Seattle examine the carcass of a gray whale after it washed up on the coast of Washington's Olympic Peninsula, just north of Kalaloch Campground in Olympic National Park. Federal scientists on Friday, May 31 opened an investigation into what is causing a spike in gray whale deaths along the West Coast this year. So far, about 70 whales have stranded on the coasts of Washington, Oregon, Alaska and California, the most since 2000. (AP Photo/Gene Johnson)

In this undated photo provided by the New England Aquarium in May 2019, Dr. Rosalind Rolland, Director of Ocean Health and a Senior Scientist in the Research Department at the New England Aquarium in Boston, poses on a boat next to a southern right whale taken during an expedition to the Auckland Islands, an archipelago of New Zealand. Whale researchers in New England say they’ve found a new way to measure the amount of stress felt by giant whales, and the technique could help protect the massive sea creatures.
