Research at the University of Southampton determined that the 2010 eruption of Eyjafjallajökull supplied dissolved iron to a large area of the North Atlantic. This stimulated photoplankton growth but the abundance of iron caused the rapid removal of biological nitrate which applied a throttle on the phytoplankton.
“Warmer spring temperatures since 1980 are causing an estimated 20 percent loss of snow cover across the Rocky Mountains of western North America. [...] Runoff from Rocky Mountain winter snowpack accounts for 60 to 80 percent of the annual water supply for more than 70 million people living in the western U.S.
Researchers have discovered evidence of life 500 meters below the seafloor of the Juan de Fuca Ridge. “They found genetic evidence of Methanosarcinales, anaerobic archaea known to metabolize methane. Further experiments showed that microbes have affected the chemical signature of sulfur in the host basalt, suggesting they could harness energy from the breakdown of sulfates.” Quoted from the Deep Carbon Observatory press release.
Exactly where the extra methane, a powerful greenhouse gas, is coming from in Los Angeles has finally been identified. [...] The research explains why the estimates of methane given off by various sources are 35 percent lower than the levels that have actually been measured in the atmosphere.
Energy companies have submitted permit requests for 20 natural gas export projects. The projects will create jobs, income for natural gas companies and property owners, and improve our trade balance. Opponents believe that exports will increase prices and accelerate the landscape impact of drilling activity.
“Seismic activity at Pavlof Volcano increased this morning commensurate with the presence of an intense thermal anomaly at the summit observed in latest satellite imagery. Similar patterns of seismicity and elevated surface temperatures have previously signaled the onset of eruptive activity at Pavlof. Although not yet visually confirmed, a low-level eruption of lava has likely begun from a summit vent.” Quoted from the Alaska Volcano Observatory.
Carbon dioxide levels reported at Mauna Loa Observatory and several other locations are breaking the 400 PPM level. Researchers believe that carbon dioxide levels have not been this high for millions of years.
“The team operating NASA’s Curiosity Mars rover has selected a second target rock for drilling and sampling. The rover will set course to the drilling location in coming days.” Quoted from the NASA press release.
In this Arizona Public Media video, Jane Poynter interviews Lee Allison, Director of the Arizona Geological Survey on the benefits of geothermalenergy along with how a project led by AGS is making geothermal data and data analysis tools available to the public.
“In 2012, the United States became a net exporter of liquefied petroleum gases (LPG) for the first time. LPG includes the natural gas liquids (NGL) components ethane, propane, butanes, and marketed refinery olefins.” Quoted from the Energy Information Administration press release.
“Researchers studying the origin of cirrus clouds have found that these thin, wispy trails of ice crystals are formed primarily on dust particles and some unusual combinations of metal particles – both of which may be influenced by human activities.” Quoted from the Oregon State University press release.
