Asian Air Pollution In Hawaii Is Tied To Climate Variability
2014-01-28 12:48:57

Princeton University Air pollution from Asia has been rising for several decades but Hawaii had seemed to escape the ozone pollution that drifts east with the springtime winds. Now a team of researchers has found that shifts in atmospheric circulation explain the trends in Hawaiian ozone pollution. The researchers found that since the mid-1990s, these shifts in atmospheric circulation have caused Asian ozone pollution reaching Hawaii to be relatively low in spring but rise significantly...

Increased Mercury Levels In Arctic Ice Found Pushing Into Sea Water
2014-01-16 10:15:32

Gerard LeBlond for redorbit.com - Your Universe Online Researchers Dr. Chris Moore and Dr. Daniel Obrist, from Nevada's Desert Research Institute, have recently discovered an increased level of mercury in Arctic sea ice. The study, published in the journal Nature, also found that the element is contaminating sea water below. The researchers claim that the air above large cracks found in the ice of the Arctic is mixing vigorously pushing mercury down to the exposed seawater. This process...

Global Warming Is Changing The Chemistry Of Ice

redOrbit Staff & Wire Reports - Your Universe Online Researchers analyzing the atmosphere above the Alaskan city of Barrow have found unexpectedly high levels of molecular chlorine in the air, according to research appearing in Sunday’s edition of the journal Nature Geoscience. The substance, which comes from sea salt that is released when ice in the region melts, interacts with sunlight to create highly reactive chlorine atoms, the researchers said. Those atoms can increase the...
