WHO declares Ebola outbreak in Congo a global health emergency
The World Health Organization declared the new Ebola outbreak in the Democratic Republic of Congo a public health emergency of international concern, citing rising cross-border risk. Officials noted it is not considered a pandemic emergency, and there is no known vaccine for this Bundibugyo strain yet, though an experimental candidate is being studied .
Scientists rebut US government climate claims
A group of leading climate scientists formally challenged a US Department of Energy report they say misrepresented evidence on human-caused warming. In a new analysis, they reaffirmed the well-established climate fingerprint of tropospheric warming and stratospheric cooling, warning the report should not be used in regulatory decisions .
Climate change is reducing oxygen in rivers worldwide
A recent climate story highlighted evidence that warming is slowly lowering oxygen levels in rivers around the world. Researchers warn that this trend could threaten fish, aquatic ecosystems, and other river life as temperatures continue to rise .
Antarctica is melting from below faster than expected
Scientists reported that hidden warm-water pathways beneath Antarctica’s ice shelves may be accelerating melting and sea-level rise. The findings suggest ice loss could be happening faster than many earlier projections anticipated .
Deep drilling begins at Thwaites Glacier
Researchers are drilling into the Thwaites Glacier, one of the most important glaciers for future sea-level rise. The work is technically difficult but aims to recover samples and data that could improve understanding of how quickly the glacier may destabilize .
New study explains how CO2 cools the upper atmosphere
A Columbia Climate School analysis explains how carbon dioxide affects different layers of Earth’s atmosphere. The study says CO2 helps warm the surface while cooling the upper atmosphere by interacting with different wavelengths of light .
U.S. climate science cuts could harm global sea-level research
Scientists warned that cuts to U.S. sea-level research could erase decades of progress just as rising seas create greater need for monitoring and forecasting. The article argues that reduced funding and data gaps could weaken decision-making worldwide .
Climate researchers defend the human fingerprint in satellite data
New analysis cited in the climate-science dispute says satellite observations match long-predicted signs of human-driven warming. Researchers emphasize that warming of the lower atmosphere and cooling of the stratosphere are strong, measurable indicators of greenhouse-gas influence .
Officials intensify cross-border Ebola surveillance
Following the Congo outbreak declaration, the African CDC said it is working with health agencies, nonprofits, and pharmaceutical firms to strengthen surveillance and outbreak response. Health authorities are monitoring the spread closely, especially after a related death in Uganda was reported .
Scientists warn the Congo Ebola outbreak may already be large
Public health experts said the outbreak could be larger than initially recognized, with one specialist noting it may already be widespread despite late detection. The strain is less common than the Zaire strain, which makes it less understood and harder to control .
