A 2021 Nature Geoscience paper argued that the Atlantic Meridional Overturning Circulation (AMOC) started slowing in the 19th century, and slowed more in the mid-20th century. But a new Nature Geoscience paper suggests that AMOC changes are still uncertain.
A newly published study suggests a major sea-surface freshening during the mid-20th century, and a southward migration of the Intertropical Convergence Zone, affecting tropical rainfall patterns.
Better understanding of this ozone sink is essential for improved modeling and prediction of air pollution, ecosystem health, and climate .
A team of scientists partially funded by CPO's Atmospheric Chemistry, Carbon Cycle, & Climate (AC4) program published a Chemical Reviews article on the chemistry of atmospheric "brown carbon,"-- the…
With help from NOAA, a caucus of Chicago’s metropolitan mayors released one of the first regional climate plans in the United States. It calls for reducing greenhouse gas emissions by at least 80 percent from 2005 levels by 2050.
Tropical storms like 2011’s Hurricane Irene experienced cooling in the coastal surface waters ahead of the eye of the hurricane, which reduced storm intensity, according to a CPO-funded study by ...
Learn what goes into growing these staples of holiday festivities, and how they are affected by weather and climate.
Members of the Carolinas Integrated Sciences & Assessments (CISA), a NOAA RISA team, compiled an integrated assessment of the conditions which contributed to the October 2015 extreme rainfall and ...
New research shows that atmospheric concentrations of a class of ozone-depleting chemicals used as refrigerants, foam blowing agents, and solvents peaked in 2021, and are now beginning to decline as nations comply with Montreal Protocol restrictions.
