Lakes Changing Color due to Climate Change

What a Lake's Color can tell you about its condition

Scientists have discovered that the warmer a lake gets, the more pigmented their color gets. Lakes with high levels of phytoplankton become greener in warmer temperatures because it increases. Lakes with a blue color become even bluer in warmer temperature because its levels of phytoplankton decrease. The warming temperatures either increases the phytoplankton or decreases the amount of animals that would eat it.  The blue lakes trap the nutrients needed for the phytoplankton at the bottom of the lake due to the heat that the lake only gets bluer as the temperatures get warmer.

    This is an interesting example of how climate change is effecting our environment in new ways. Not only is the temperature of the lakes producing effects that we are not accustomed to, but it is also causing detrimental effects to the lakes inhabitants. This is just another example of why climate change is ever pressing and requires attention in order to start combating it.

    I agree with Mackenzie in saying that this is a very interesting article topic. I would have never guessed that climate change would affect the color of a lake's water. I always just assumed that some lakes look blue and other had more of a greenish tint to their water color just because that how they looked. It was interesting to read that the color of a lake's water is greatly determined by the amount of phytoplankton and nutrients in the water.

    I have seen some interesting lake and lagoon colors (like a deep deep blue or crystal clear, sometimes a pinkish color). I wonder what is causing them to take that pigment. These lakes are tourist attractions so I wonder if there is an effect on those who swim in these bodies of water.

    I never realized that when the lakes change color it is because of the climate change. I find this very interesting how lake's react to climate change by changing their colors.

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
