Unusually intense spring heat is spreading across the Western and Central U.S., with forecasts that about 800 high-temperature records may be tied or broken at 165 locations over the next week. March was the warmest on record so far for daytime highs nationally, and this early-season heat surge is expanding into April, raising wildfire and emergency risks. Similar record-breaking early heat in Western Europe, including shattered UK temperature records and heat-related deaths, suggests these anomalies are part of a broader pattern of early-season extremes. New research indicating that colored microplastics absorb sunlight suggests a possible small additional factor that could marginally amplify regional temperature spikes and fire danger.
