A decade of BGC-Argo and plankton records shows North Pacific heatwaves reshape food webs and trap small particles in midwater, slowing deep-ocean carbon export. Impacts vary by event, underscoring the need for sustained ocean monitoring.

Architects have a responsibility that is being tragically ignored. The built environment is responsible for 40% of emissions. You can’t graduate from design school over the past 25 yrs without knowing that. Yet we still crank out and celebrate projects with high upfront and operational carbon. Why?
So much money is being invested in new parks to help lower Manhattan become resilient to climate change and yet the architecture and landscape architecture are blind to their own climate impacts, with large carbon footprints and no on-site renewables. Missed opportunity to showcase net-zero design.
