If greenhouse gas emissions stopped now, Earth still would likely get warmer
While governments debate about potential policies that might curb the emission of greenhouse gases, new University of Washington research shows that the world is already committed to a warmer climate because of emissions that have occurred up to no…
Rising seas will affect major US coastal cities by 2100
Rising sea levels could threaten an average of 9 percent of the land within 180 U.S. coastal cities by 2100, according to new research led by University of Arizona scientists.
The Gulf and southern Atlantic coasts will be particularly hard hi…
Ocean fertilization summary for policymakers published
Failure to tackle rising greenhouse gas emissions effectively has led to intensifying debate on geoengineering – deliberate large-scale schemes to slow the rate at which Earth is heating up. The public debate often mixes opinion with fact so scie…
The undead may influence biodiversity, greenhouse gas emissions
EAST LANSING, Mich. — It’s commonly known, at least among microbiologists, that microbes have an additional option to living or dying — dormancy.
Dormant microbes are less like zombies and more like hibernating bears. What isn’t known, howev…
