WHO experts urge climate-health emergency declaration
A WHO-convened pan-European commission says the climate crisis should be declared a public health emergency of international concern, or millions more people could die unnecessarily. The report is set to go to European ministers on Sunday ahead of the WHO World Health Assembly and cites extreme heat, floods, vector-borne disease, food and water insecurity, air pollution and wildfire smoke. It also calls for ending fossil-fuel subsidies, expanding climate-health impact assessments and treating climate change as a mental health crisis.
Why it matters
A PHEIC-style declaration would elevate climate from a long-term policy issue to the highest level of international health alert.

The Guardian coverageNew Jersey wildfire risk climbs after winter delays
New Jersey wildfire officials say fire spread risk is elevated by warmer temperatures, below-normal precipitation, low humidity and stronger winds. A 14-alarm blaze in Belleville Township on May 3 burned for days under those conditions, while February snow from a nor'easter and a 2024 drought limited prescribed burning. The state says it has treated only 35% of a 25,000-acre burn goal, with roughly a quarter of homes in the wildland-urban interface.
Why it matters
It shows how prevention backlogs can collide with worsening fire weather in a densely populated state.

Inside Climate News coverageStates advance geothermal repurposing for abandoned wells
Oklahoma, Alabama, North Dakota and Colorado are moving to create rules or studies for converting inactive oil and gas wells into geothermal or underground energy-storage sites. Oklahoma's Senate is considering a Well Repurposing Act after the House passed it in March, Alabama enacted a conversion law last month, North Dakota ordered a feasibility study and Colorado launched a technical study. Researchers at the University of Oklahoma and Penn State are testing whether old wells can provide direct-use heat, campus heating and storage, but the concept remains early-stage and technically difficult.
Why it matters
If the approach proves viable, it could turn leaking fossil infrastructure into a source of clean heat and storage.

Will WHO adopt the climate emergency call?
The commission's recommendation could materially change how climate threats are coordinated across the global health system.
OPEN QUESTION
Can abandoned-well geothermal scale economically?
The state policy push is real, but the technical and cost hurdles still determine whether it becomes a deployable climate solution.
