Leaders confront climate costs, AI energy use and soaring fuel prices in New York

In New York this week, government leaders and corporate executives convened for the UN General Assembly and Climate Week to grapple with intensifying climate threats. Recent heatwaves, wildfires and a sudden flood that killed over 1,300 people on the Nepal-China border highlight the human toll, while conflicts in Iran and Ukraine have driven fossil-fuel prices to record highs, raising food and energy inflation globally.

Delegates warned that the surge in artificial-intelligence workloads and data-center construction, now using about 1.5% of global electricity, could boost carbon emissions and household energy bills unless sourced from zero-emission power. Climate analysts stressed the urgency of accelerating renewable-energy deployment, noting that 2025 saw a peak addition of 693 gigawatts but that capacity must increase even faster through 2030. The dialogue also noted the paradox that geopolitical actions by leaders such as Donald Trump and Vladimir Putin, intended to protect fossil fuels, are inadvertently hastening the shift toward renewables.
