Dense Ice

As the glaciers off the coast of Greenland go through melt cycles water drips into crevasses and then freeze. This is leading to denser sheets of ice. The problem with dense ice is that if there are larger cracks near the bedrock layer it will create lubrication for the glaciers to slide on creating the possibility for the ice to slide into the ocean raising overall sea level. Another issue surrounding this is that ice does not reflect sunlight like snow does. this means that the ice will melt even faster contributing to rising sea levels more rapidly. I think this is incredibly important because the melting of glaciers is already causing sea levels to rise by millimeters each year. Imagine how drastically that can change if the glaciers actually do start to break off into the ocean in larger more prevalent chunks than we have now.

    If the glaciers would begin to slide into the ocean, I wonder what the predicted rise in sea level would be? Would it create a natural disaster or only accelerate the rising of the oceans?

    With rising sea levels, I wonder how much this will change the world as we know it. Eventually, it will change the landscape of the entire Earth, PA could be a beach front property if levels continue to rise, which would cause many problems and increase the population issues that the world faces.

Dual-fuel vehicles

A recent study shows that dual- fuel vehicles are benefiting the population but, turns out they are costing the environment. While substituting gasoline for ethanol gases, it causes an increase of ultra fine particle matter, with a 30% increase of atmospheric concentration. The problem is that they are less then 50 nanometers in diameter. The nano particles are also not track or regulated by the environmental agencies. We inhale these gases everyday, inhaling ethanol. The most practical way to reduce greenhouse gases is using electric, hybrid and biofuel care.   https://www.sciencedaily.com/releases/2017/08/170828124546.htm

Acid Zone in Chesapeake Bay Found

     According to the University of Delaware, the Chesapeake Bay is becoming acidic as it has gone to 7.4 pH from an average of 8.2. The oxidation of ammonia and hydrogen sulfide may be the factor that is leading to the higher acidity levels in coastal oceans, but it can eventually lead to more of open oceans. Naturally the waters of the Chesapeake Bay have a regulatory system that holds back the increase of acidity levels in the area, and this works as the dissolving of living shells, non-living aragonite, and calcite minerals. Though nature has a path to keep the waters in the Chesapeake Bay, humans should take more care of our Earth as we have a role in polluting the water and rising the acidity levels in coastal oceans. https://www.sciencedaily.com/releases/2017/08/170828093737.htm
