A University of Wyoming researcher contributed to a paper that determined a “Snowball Earth” event actually took place 100 million years earlier than previously projected, and a rise in the planet’s oxidation resulted from a number of different continents -- including what is now Wyoming -- that were once connected.

Tropical Cyclone 04S formed north of La Reunion Island on February 4 and continued to track slowly toward the island. This ended an unusual drought of tropical cyclone formation in that part of the Indian Ocean that began in July 2016. When NASA's Terra passed over the newly-formed tropical cyclone imagery showed a concentration of strong thunderstorms around the center of the compact storm. The storm was later renamed Tropical Cyclone Carlos.

Researchers have developed an infrared imaging system that could one day offer low-cost, real-time detection of methane gas leaks in pipelines and at oil and gas facilities. Leaks of methane, the primary component of natural gas, can be costly and dangerous while also contributing to climate change as a greenhouse gas.

Nitrogen deposition caused by human activities can lead to an increased phytoplankton production in boreal lakes. The response of boreal lakes to nitrogen deposition will strongly depend on each lake’s content of organic carbon, which are predicted to increase with future warmer and wetter climate. This according to a thesis at Umeå University.

The worldwide increase of inorganic nitrogen deposition via fossil fuel combustion, fertilization and forestry has been intervening drastically with the Earths’ natural nitrogen cycle. Food webs of boreal lakes, that have historically received little nitrogen deposition until now, are expected to be especially susceptible to increases in inorganic nitrogen availability.

As the world struggles to make progress to limit climate change, researchers are finding ways to adapt to warmer winter temperatures — by developing environmentally friendly ways of producing artificial snow.

Chances are if you know anything about Norway, you know it’s a place where skiing was born.

Norse mythology describes gods and goddesses hunting on skis, and 4000–year-old petroglyphs from northern Norway include some of the earliest known drawings of people on skis. One of the most recognizable Norwegian paintings worldwide depicts two skiers in 1206 fleeing to safety with the country’s two-year-old prince, Håkon Håkonsson.

World-first research on the Great Barrier Reef has shown how ‘weed-like’ algae will kill vital coral because of increased carbon dioxide concentrations in the atmosphere.

How viruses like Ebola, influenza or even the common cold adapt is a question that affects the health of everyone on earth.  A new Yale University study reveals that gradual exposure to new host species leads to major genetic changes in these pathogens — and possibly makes them more dangerous.

Global methane and ethane emissions from oil production from 1980 to 2012 were far higher than previous estimates show, according to a new study which for the first time takes into account different production management systems and geological conditions around the world.

Methane is a potent greenhouse gas, which scientists rank as the second-most important contributor to climate change after carbon dioxide. Yet while methane concentrations in the atmosphere can be easily measured, it is difficult to determine the contribution of different sources, whether human or natural. This is necessary information for reducing emissions.

Dust released by an active coal mine in Svalbard, Norway, reduced the spectral reflectance of nearby snow and ice by up to 84 percent, according to new University of Colorado Boulder-led research.

The study illustrates the significant, localized role that dark-colored particulates — which absorb more solar radiation than light-colored snow and keep more heat closer to the Earth’s surface — can play in hastening Arctic ice melt.   

The study was published today in the Journal of Geophysical Research: Atmospheres, a publication of the American Geophysical Union.

In the global effort to mitigate carbon dioxide levels in the atmosphere, all options are on the table—including help from nature. Recent research suggests that healthy, intact coastal wetland ecosystems such as mangrove forests, tidal marshes and seagrass meadows are particularly good at drawing carbon dioxide from the atmosphere and storing it for hundreds to thousands of years.
