Scientists Studying Tiny Cloud-Forming Particles in Nunavut Air

Wednesday, July 9th, 2014

In order to see your breath in winter, there have to be tiny particles floating in the air so the moisture in your breath will have something to cling to and form molecules visible to the human eye. Those tiny airborne particles, known as aerosols, come from naturally existing things such as plant pollen, dust and sea spray, and also from human made pollution such as black carbon. Scientists are not just looking for air pollution that can create health problems, however.  They are also seeking to determine how the particles affect cloud formation and may lead to climate changes.  Nunatsiaq Online

Climate change could cause some fish species to shrink by nearly 25%

Wednesday, October 3rd, 2012

A new study that modeled the impact of climate change on more than 600 fish species says that most of those species could shrink by between 14 and 24 percent by the year 2050. Additionally, as the concentration of oxygen in the Earth’s waters decreases, some species may move away from equatorial waters toward the Arctic. The study, conducted by researchers from the University of British Columbia, Princeton University and the National Oceanic and Atmospheric Administration, has broad implications — not only for the Earth’s ecosystems, but for the seafood industry as well as sport fishermen. If that doesn’t get you excited, take this theoretical figure: in 2011, Alaska brought home 5.4 billion pounds of seafood worth $1.9 billion, by far the most among U.S. states. If that catch were reduced by 25 percent, it would mean a loss of 1.35 billion pounds and $475 million from state fisheries. Alaska Dispatch
