The results of a new high-resolution climate model indicate that global warming made the 2018 Cape Town “Day Zero” drought five to six times more likely than it would have been in the 19th century. Models project that, without significant reductions in greenhouse gas emissions, such extreme droughts in the Cape Town region will become more frequent, occurring every few years or almost every year by the end of the 21st century.
Even in years with record-breaking fire seasons, overall fire occurrence remains below historical levels, but fire severity has increased, contributing to greater forest loss and heightened risk.
Called El Niño’s little brother, Atlantic Niño is the Atlantic equivalent of El Niño-Southern Oscillation (ENSO). New research finds that Atlantic Niño can be induced by the Indian Ocean Dipole, independent of ENSO activity.
The South Atlantic Ocean is the only ocean basin that transports heat towards the equator instead of the poles . It transfers vast amounts of Pacific and Indian Ocean waters to the North Atlantic. New research shows the South Atlantic Ocean has warmed from its surface to the deep ocean, upper ocean salinity has increased, and intermediate, deep water masses are freshening.
New research finds that diffusion of sunlight from particles in Earth’s stratosphere could indirectly make marine clouds thousands of feet below more reflective.
November 30 marks the official end of the 2024 Atlantic hurricane season. Throughout this active season, NOAA scientists set new records in tropical cyclone research.
For decades, NOAA has used jets to collect data from around hurricanes. A new study finds that a second flight path closer to the hurricane’s center improves forecast accuracy.

Urban areas can better reduce their greenhouse gas emissions with detailed, timely, comprehensive emission data. The Integrated Global Greenhouse Gas Information System (IG3IS), intended to meet new reporting goals, is now open for comment.
