(55,894 posts)And here's the thing that climate change deniers ignore which applies here-
The capacity for Nature to bounce back after a dry spell/sardine crash is severely undermined by human activity.
Like a healthy person can survive and bounce back after pneumonia but a heavy smoker might succumb to it because their lungs and heart in such bad condition.

The reason for the drop is unclear. Sardine populations are famously volatile, but the decline is the steepest since the collapse of the sardine fishery in the mid-20th century. And their numbers are projected to keep sliding.
One factor is a naturally occurring climate cycle known as the Pacific Decadal Oscillation, which in recent years has brought cold, nutrient-rich water to the West Coast. While those conditions have brought a boom in some species, such as market squid, they have repelled sardines.

Since the 1940s scientists have debated how much of the collapse was caused by ocean conditions and how much by overfishing. Now, researchers are posing the same question.
"It's a terribly difficult scientific problem," said Russ Vetter, director of the Fisheries Resources Division at NOAA's Southwest Fisheries Science Center.
