Southern California experienced a surprising surge in temperatures this week, with several locations shattering February records. While a brief heat spike isn't uncommon, experts are increasingly focused on the broader trend: a warming climate leading to more frequent and intense heat events.

Why it matters

The recent heatwave underscores the growing pattern of climate change, with implications for public health, energy grids, agriculture, and ecosystems. Adapting to these changes will require comprehensive strategies from communities across Southern California.

The details

A combination of factors, including a persistent high-pressure system and the influence of Santa Ana winds, pushed temperatures significantly above seasonal norms. Record-breaking temperatures were recorded at key locations like LAX (87°F), UCLA (88°F), and Long Beach (88°F). While the forecast calls for cooling, the event highlights a broader upward trend in average temperatures and extreme heat days across the state.
