California’s ongoing extreme drought must be a lesson for managing water in a warmer, more densely populated world, says a team of NOAA and University of California climatologists and hydrologists in an essay this week in Nature.

With the August 22 arrival of the NASA Global Hawk unmanned aircraft on Virginia’s eastern shore, scientists and pilots are now ready to start the NOAA-led mission to improve hurricane forecasts of track and intensity using data collected by the Global Hawk during the season’s hurricanes.

New research appearing online today in the journal Nature Climate Change by NOAA and partners forecasts the effects of climate change on countries' economic output and suggests that rising greenhouse gases may contribute to more extreme El Niños, the climate phenomenon that can trigger severe weather.

Scientists from NOAA and the Cooperative Institute for Marine and Atmospheric Studies at the University of Miami have documented a dramatic shift from vibrant coral communities to carpets of algae in remote Pacific Ocean waters where an underwater volcano spews carbon dioxide.

NOAA Ship Okeanos Explorer will begin two months of dives using unmanned remotely operated vehicles, or ROVs, to explore marine protected areas in the central Pacific Ocean. Starting on Aug. 1, anyone with an internet connection can virtually explore the deep sea with scientists and researchers from their computer or mobile device.

The hot and dry Santa Ana winds are associated with many of Southern California’s destructive wildfires, and even take the blame for tense, ugly moods. Now, NOAA researchers have found that on occasion the winds have an accomplice in contributing to California’s wildfires: atmospheric events known as stratospheric intrusions, which bring extremely dry air from the upper atmosphere down to the surface.

New collaborative research between NOAA, University of Alaska and an Alaskan shellfish hatchery shows that ocean acidification may make it difficult for Alaskan coastal waters to support shellfish hatcheries by 2040 unless costly mitigation efforts are installed to modify seawater used in the hatcheries.

From our nation’s founding, the Fourth of July has been synonymous with fireworks. While many grew up learning that fireworks can be dangerous to the eyes and hands if not handled properly, fireworks also produce air pollutants, including particulate matter, that are linked to short-term or long-term health effects.
NOAA has authored a new study appearing in the journal Atmospheric Environment that quantifies the surge in fine particulate matter – particles that are two and one half microns in diameter (PM2.5) – on July 4, using observations from the 315 U.S. air quality monitoring sites that operated from 1999 to 2013. The new study is the first nationwide quantitative analysis of the effects.

New research by NOAA, University of Alaska, and Woods Hole Oceanographic Institution in the journal Oceanography shows that surface waters of the Chukchi and Beaufort seas could reach levels of acidity that threaten the ability of animals to build and maintain their shells by 2030, with the Bering Sea reaching this level of acidity by 2044.
