California's oceans are breaking temperature records during a historic heat wave, with Scripps Pier recording 71°F in March—its warmest on record—breaking daily marks for days. A strong marine heat wave has developed off Southern California's coast, driven by an atmospheric ridge that weakened upwelling, allowing warm surface water to dominate instead of cold, nutrient-rich deep water rising. This pattern threatens ecological and meteorological impacts into summer, with experts monitoring whether conditions worsen or fade. These unprecedented ocean temperatures signal the intensifying effects of climate change on marine ecosystems.

More notes from the live chat by Weather West (Dr. Daniel Swain) on the chaos being wrought upon the National Weather Service:
Dept of Commerce terminated an agreement with a university regarding weather/climate research stated "this cooperative agreement promotes exaggerated climate threats...promoting anxiety..."
A doc from the White House states that the proposed close the NOAA office that does and funds research on weather and oceanographic. NASA is targeted for larger cuts regarding planetary research. Many cooperative research centers will be closed. Proposed is the canceling the partnership between NASA and NOAA, which would end weather satellite updates.
