Why do dead whales keep washing up in San Francisco?

The stench lingered on the evening breeze as seabirds circled the animal, a juvenile fin whale. The whale was the fifth to wash ashore in the area this month. The other four were gray whales – giant cetaceans who migrate an astounding 11,000 miles each year from Alaska to Baja and back – all found on beaches near the city over a span of just eight days.

California s legacy of DDT waste: underwater dump site uncovers a toxic history

California’s legacy of DDT waste: underwater dump site uncovers a toxic history Aaron Cantu in Los Angeles © Provided by The Guardian Photograph: David Valentine/AP The discovery of tens of thousands of underwater barrels containing what scientists believe to be chemical waste has raised alarm and reopened scrutiny into a history of toxic dumping that persisted off the California coast into the 1970s. A team of scientists announced this week that they had found more than 25,000 containers, many of which they believe to be DDT waste, which has been linked to cancer and disease in humans and mass die off events in the natural world. The barrels cover a seafloor area double the size of Manhattan off the coast of the Santa Catalina Island, near Los Angeles.

The expedition was the first of its kind to lay bare the scale of the offshore dumping that occurred for decades, and its size “was a surprise to everyone who has worked with the data and sailed at sea”, said Eric Terrill, the chief scientist of the expedition and director of the Marine Physical Laboratory at Scripps Institution of Oceanography, at a press conference about the findings. “As we started to run the survey and realized what we were beginning to observe on the seafloor, it was staggering to see the spatial extent.” Scientists who spoke with the Guardian expressed shock at the extent of the dump ground. And hopes about the innovative technology used to map out the area is tempered by looming questions about what to do about the waste – not just off the coast of Los Angeles, but in sea waters across the country that various industries treated as a cheap alternative to landfills for decades.

What to Know About California s Drought - The New York Times

Yes, I’m referring to the drought gripping much of the state. It’s a problem that scientists are expecting to get worse this year, particularly because tinder-dry conditions are likely to lead to another devastating — not to mention long — wildfire season. But experts say the outlook isn’t all bad.
