Science and environment coverage today is dominated by a stark warning from Europe’s early, record-breaking heatwave, which UN climate chief Simon Stiell says is a direct signal of a worsening fossil-fuel-driven climate crisis. With deaths reported in France and drownings in Britain as people tried to escape the heat, the episode underscores how rapidly extreme weather is becoming a public-safety issue, not just an environmental one. Elsewhere, technology and safety were in focus after an Air India Boeing 777 bound for San Francisco turned back to Delhi following a mid-flight technical problem, landing safely after hours in the air. And in the media world, veteran “60 Minutes” correspondent Sharyn Alfonsi says CBS declined to renew her contract after she challenged the shelving of a report on El Salvador’s CECOT prison, raising fresh questions about editorial independence and newsroom pressure.
