Sharks Surge Summer

Southern California is expected to see more white sharks this summer, due to unusually warm waters and a brewing El Niño.
Marine biologist Chris Lowe notes baby white sharks have been spotted earlier than usual, suggesting warmer temperatures trigger earlier births.
Predictions indicate a significant July influx of sharks, including potential arrivals of tiger and bull sharks during strong El Niño events.

Marine Heatwave Threatens

Record-high water temperatures along California's coastline are caused by a persistent high-pressure system, not El Niño currents.
The marine heatwave threatens phytoplankton, sea lions, and halibut by potentially disrupting upwelling essential to ecosystem health.
Warmer waters attract tuna and boost recreational activities, but overall effects of these heatwaves are detrimental.
Experts emphasize the need to understand the causes and the potential long-term consequences for marine ecosystems.
