Key developments
UN General Assembly backs world court climate opinion
The UN General Assembly adopted a resolution endorsing a landmark World Court advisory opinion that says countries have legal obligations to address climate change. The vote was 141 in favor, eight against, and 28 abstentions; the resolution urges states to transition away from fossil fuels in energy systems, asks the next UN secretary-general to report in 2027, and adds a follow-up item for 2028. Delegates also rejected amendments that would have weakened the legal framing, shifted the temperature reference from 1.5C to 2C, or removed the 2028 review.
Why it matters
It strengthens the legal and diplomatic case for more aggressive climate action and future accountability.

Carbon Brief coverageStudy projects severe range loss for plants
Researchers modeled future ranges for more than 67,000 vascular plant species using millions of occurrence records and emissions scenarios for 2081-2100. The study, published in Science and reported by Marta Serafinko, found that 7% to 16% of species could lose more than 90% of their suitable range, including examples such as Catalina ironwood, bluish spike-moss, and about one-third of Eucalyptus species. The authors said extinction risk changed little even when plants were allowed unrestricted dispersal, suggesting that shrinking habitat, not just migration limits, is the main driver.
Why it matters
It suggests climate impacts on plant biodiversity may be broader and harder to offset than assisted migration alone can solve.

AOL.com coverageNOAA forecasts below-average hurricane season
NOAA said the Atlantic is likely to see 8 to 14 named storms, 3 to 6 hurricanes, and 1 to 3 major hurricanes this year, with El Niño possibly suppressing storm formation. The agency also launched new flood prediction tools, including street-level mapping and an experimental Urban Rain Rate Dashboard for 60 cities, and said it will use uncrewed aircraft data in intensity models for the first time. Climate scientists quoted in the report warned that record-warm oceans linked to greenhouse-gas pollution can still drive stronger rainfall and more intense storms.
Why it matters
A quieter forecast does not reduce flood risk, and NOAA is adding tools to better track that risk in a warming climate.

OPEN QUESTION
Will the UN resolution change domestic policy?
The resolution and World Court opinion raise the question of whether states will translate legal language into enforceable national action.
OPEN QUESTION
Can plant conservation offset shrinking habitats?
The plant study found extinction risk stayed high even with unlimited dispersal, suggesting habitat restoration and protection may matter more than relocation alone.
