Blood Red Skies Over China Explained 300 Years Later

In September of 1770, the above China, Japan, and Korea changed to what was described as an "eerie red" colored aurora. This continued for 8 nights. No one could explain this phenomenon and it was eventually forgotten. However, researchers recently began investigating the event again after finding historical documents in East Asia describing it. They have found that this was most likely caused by a geomagnetic storm. A geomagnetic storm occurs when the magnetosphere of Earth is hit by solar eruptions. Sunspots occur with most geomagnetic storms, and there were also drawings and records of sunspots occurring at the same time as the auroras.

I found this article very interesting because I have never heard about geomagnetic storms before. There were informative descriptions about what geomagnetic storms are and what can occur along with them. Multiple forms of evidence proving that these auroras were caused by one of the storms were also discussed in the article.

    I think this article is really cool, I wonder if it correlates to why we see the Northern Lights the way we do! If so that would be a really cool relation.

    I think it would've been a little scary to see an 'eerie red' color in the sky, but it would also probably be really cool and beautiful to see. Like Ariyanna said, it sounds like this relates to the Northern Lights.

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
