Study flags extreme flood risk on coasts
Weather reports that a University of Alabama team assessed flood exposure from Texas to Maine using 16 factors, FEMA damage records, and three AI models. The study says 17.5 million people are at very high flood risk and another 17 million are at high risk; for FEMA-style top 1% floods, 4.3 million are in the highest-risk tier and 20.5 million in the next tier. New York City and New Orleans stand out, with New Orleans placing about 99% of residents in the top two risk categories.
Why it matters
It gives coastal planners and emergency managers a sharper map of where flood losses are likely to be concentrated as climate-driven risk keeps rising.

Weather coverageSanta Marta opens first fossil-fuel phaseout conference
The Conversation says delegates from 53 countries and the European Union are meeting in Santa Marta, Colombia, for the first Conference on Transitioning Away from Fossil Fuels. The gathering is designed as a concrete coalition process rather than formal UN treaty talks, with work organized around fossil-revenue dependence, supply-and-demand transition, and climate diplomacy, including investor-state dispute settlement. The co-hosts are expected to issue a report, and the COP30 presidency has said it will consider the results for a roadmap to COP31.
Why it matters
It is a rare attempt to turn COP28-era fossil-fuel phaseout language into an actionable, smaller-scale diplomatic process.

THE CONVERSATION
The Conversation coverageNYK, HEPCO launch onboard carbon capture trial
Carbon Herald reports that Nippon Yusen Kabushiki Kaisha and Hokkaido Electric Power Company signed an MOU to explore onboard carbon capture and storage for maritime transport. The three-year demonstration, running through fiscal 2028, is planned for Tomakomai using NYK's coal carrier Pirika Moshiri Maru and will study capture-system design, ship operations, and how captured CO2 could be offloaded, transported, reused, or stored.
Why it matters
It tests whether ship-based carbon capture can become a practical decarbonization option for one of shipping's hardest-to-abate segments.

OPEN QUESTION
Which coastal cities act on the risk map first?
The new flood-risk rankings will matter most if cities like New York and New Orleans use them to change zoning, drainage, and retreat planning.
OPEN QUESTION
Will Santa Marta yield a phaseout roadmap?
The conference's value depends on whether it produces concrete commitments on fossil fuels, subsidies, and legal barriers like investor-state dispute settlement.
