Cirrus clouds form around mineral dust and metallic particles, study finds
At any given time, cirrus clouds—the thin wisps of vapor that trail across the sky—cover nearly one-third of the globe. These clouds coalesce in the upper layers of the troposphere, often more than 10 ...
Storms' lingering cold water paths restrict intensity of following tropical cyclones
It's an oceanic case of sibling rivalry. Large, first-born cyclones drink in most of the ocean's warmth, leaving cold water leftovers for sibling storms that cross its path. Pacific Northwest National Laboratory ...
NIST 'combs' the atmosphere to measure greenhouse gases
By remotely "combing" the atmosphere with a custom laser-based instrument, researchers from the National Institute of Standards and Technology (NIST), in collaboration with researchers from the National Oceanic ...
Warming Earth heading for hottest year on record (Update)
Earth is on pace to tie or even break the mark for the hottest year on record, U.S. meteorologists say.
New method efficiently estimates surface reflectivity from incoming sunlight bounced back by clouds
Capturing sunlight reflected off the Earth's surface and bounced off a cloud back to the Earth is an effective measure of surface reflectivity—or surface albedo, the measure of how mirror-like the Earth's ...
World breaks monthly heat record two times in a row (Update)
The globe is on a hot streak, setting a heat record in June. That's after the world broke a record in May.
NOAA says world in 2013 was fourth hottest on record (Update 2)
Last year tied for the fourth hottest year on record around the globe.
Safety in numbers? Not so for corals
Traditionally, it was assumed that corals do not face a risk of extinction unless they become very rare or have a very restricted range. A team of scientists from the University of Hawaii – Manoa (UHM), ...
Study finds climate link to atmospheric-river storms
(Phys.org) —A new NASA-led study of atmospheric-river storms from the Pacific Ocean may help scientists better predict major winter snowfalls that hit West Coast mountains and lead to heavy spring runoff ...
Water in stratosphere plays key role in Earth's climate
Water vapor changes in the stratosphere contribute to warmer temperatures and likely play an important role in the evolution of Earth's climate, says a research team led by a Texas A&M University professor.
US studies humpback whale endangered list removal
The National Oceanic and Atmospheric Administration has launched a review of whether it should take North Pacific humpback whales off the endangered species list.
New study shows tornadoes tend toward higher elevations and cause greater damage moving uphill
(Phys.org) —The first field investigations of the effect of terrain elevation changes on tornado path, vortex, strength and damage have yielded valuable information that could help prevent the loss of human ...
Study finds novel worm community affecting methane release in ocean
Scientists have discovered a super-charged methane seep in the ocean off New Zealand that has created its own unique food web, resulting in much more methane escaping from the ocean floor into the water column.
Seasonal carbon dioxide range expanding as more is added to Earth's atmosphere
Levels of carbon dioxide in the atmosphere rise and fall each year as plants, through photosynthesis and respiration, take up the gas in spring and summer, and release it in fall and winter.
