Arctic shipping routes quadruple as geopolitical risk reshapes global trade

The Northern Sea Route is experiencing a structural shift. Climate change has made Arctic passages viable year-round, while Houthi attacks in the Red Sea have made the traditional Suez Canal route too costly and risky for major carriers.

Google's AI Reroutes Planes to Dodge Contrails

Google and the UK are testing real-time contrail prediction to nudge aircraft into flight paths that avoid ice-crystal formations, which can warm the atmosphere as effectively as the fuel they burn. This is the first production-scale trial of a tool that bypasses regulatory delays—airlines can implement it now without hardware retrofits or new regulations, making it a climate intervention with immediate adoption pathways.
