A UBC-led research team has developed a new global coral bleaching database that could help scientists predict future bleaching events.

By examining the cooling rate of rocks that formed more than 10 miles beneath the Earth’s surface, scientists led by The University of Texas at Austin Jackson School of Geosciences have found that water probably penetrates deep into the crust and upper mantle at mid-ocean spreading zones, the places where new crust is made. The finding adds evidence to one side of a long-standing debate on how magma from the Earth’s mantle cools to form the lower layers of crust.

Nick Dygert, a postdoctoral fellow in the Jackson School’s Department of Geological Sciences, led the research which was published in May in the print edition of Earth and Planetary Science Letters. Collaborators include Peter Kelemen of Colombia University and Yan Liang of Brown University.

A vigorous weather system has generated severe weather over the mid-section of the U.S. and satellites are providing a look at it as it is moving toward the East Coast.

NASA and NOAA satellites have been tracking a storm system that has generated flooding and tornadic thunderstorms in the central U.S. and is expected bring severe weather to the U.S. Mid-Atlantic region. At NASA's Goddard Space Flight Center in Greenbelt, Maryland, data from NOAA's GOES-East satellite were used to create images and an animation of the movement of the powerful storm.

Global warming is a concept very well-known to people today, even those who are not particularly invested in such matters. However, this knowledge becomes obsolete very quickly. Take the greenhouse effect. We all have heard about the ??2 emissions and their detrimental effect on our planet. According to the US EPA data, 76% of all greenhouse gas emissions are carbon dioxide, and 16% - methane (??4). However, despite this great differential, methane is actually much more dangerous. Intergovernmental Panel on Climate Change gives a good insight into that. As per their research, the greenhouse activity of methane is 28 times higher than that of carbon dioxide in the timeframe of 100 years and 80 times higher if the next 20 years are taken into account. Moreover, methane concentration in the atmosphere grows exponentially. And the explanation for that may be derived from our distant past.

The soils and sediments beneath our feet can contain an astonishing amount of carbon – more than in all of the world’s plants and the atmosphere combined – and represents a significant potential source of the greenhouse gas carbon dioxide.

In a new study, Stanford scientists have uncovered a previously unknown mechanism that explains why microbes sometimes fail to break down all the plant and animal matter, leaving carbon underfoot. Understanding where, and how long, this buried organic matter lingers is crucial for scientists and policymakers to better predict and respond to climate change.

From atop this grassy mesa in 1967, scientists with the federal Environmental Science Services Agency carefully launched a weather balloon carrying a new instrument that could measure ozone levels from the ground to the very edge of outer space -- and radio the data back to a ground receiver.

The United States is considering a $1 trillion budget proposal to update infrastructure, including its crumbling bridges. An obstacle to spending the money wisely is that the current means of assessing bridges may underestimate their vulnerability, according to a new study published in the Journal of Infrastructure Systems. 

Case in point is a bridge along California’s iconic Big Sur coast, which collapsed in March, isolating communities and costing local businesses millions of dollars. Although California’s recent unprecedented rains were likely to damage infrastructure, standard risk assessments made it hard to identify which bridges were most vulnerable.

Tropical rainforests are often described as the “lungs of the earth,” able to essentially inhale carbon dioxide from the atmosphere and exhale oxygen in return. The faster they grow, the more they mitigate climate change by absorbing CO2.

This role has made them a hot research topic, as scientists question what will happen to this vital carbon sink long-term as temperatures rise and rainfall increases.

Conventional wisdom has held that forest growth will dramatically slow with high levels of rainfall. But CU Boulder researchers this month turned that assumption on its head with an unprecedented review of data from 150 forests that concluded just the opposite.

The ability of some Western conifer forests to recover after severe fire may become increasingly limited as the climate continues to warm, according to a new study published today in Global Change Biology, by ?HF Senior Ecologist Jonathan Thompson and fellow scientists from the Smithsonian Conservation Biology Institute (SCBI) and UVA.

Although most of the evergreen trees in the study region are well adapted to fire, the study examined whether two likely facets of climate change — hotter, drier conditions and larger, more frequent and severe wildfires — could potentially transform landscapes from forested to shrub-dominated systems.

Vertical wind shear can weaken a tropical cyclone and that's what's happening to the now weaker Tropical Depression Muifa in the Northwestern Pacific Ocean. NASA gathered rainfall information about the storm as wind shear continued to weaken it.

The Global Precipitation Measurement mission or GPM core observatory satellite again passed over Tropical Storm Muifa in the western Pacific Ocean on April 26, 2017 at 0721 UTC (3:21 a.m. EDT). GPM data revealed that there was very little precipitation around Muifa's low level center of circulation. A red tropical storm symbol shows the approximate location of tropical storm Muifa's center. Rain was measured by GPM's Dual-Frequency Precipitation Radar (DPR) falling at a rate of over 193 mm (7.6 inches) per hour in storms located well to the east of the tropical cyclone's center.
