This is what cities need to do by 2050 to meet climate goals

Urban areas make up about 75% of all worldwide carbon emissions, but by using technology that already exists, humanity could cut carbon emissions by 90% by the year 2050. About 30% of emissions could be cut if buildings were made to be more efficient in their energy consumption by improving insulation so hot or cold air doesn't leak from the buildings, or by using more eco-friendly methods to power larger buildings such as solar or wind energy. A 15% reduction in emissions could come from using better materials to build infrastructures or by reusing the buildings already in existence. Another 20% could be cut by improving public transportation or reducing the amount of carbon emissions created from using cars.

    How is a 15% emission cut possible from reusing existing buildings in urban areas? Especially since it was established that many current buildings aren't insulated properly wouldn't these buildings need to be treated to be more environmentally friendly?

    While greenhouse gas emissions are definitely a major issue in our world, I think that most of the issue lies with large corporations emitting those gasses, rather than ordinary city buildings. I think stricter regulations on those corporations would be more beneficial than reusing existing buildings, for example. Overall, it is still good to hear that major reductions of greenhouse gases can be made using current technology, but I believe their are more beneficial ways of going about it.

    It is crazy that we can reduce emissions by so much with simple things like better building materials and improving our transportation with things like energy efficient cars. I hope that we start doing some of these things because a small improvement is better than nothing. If we start to do small things like this we can start to tackle bigger issues that cause climate change.

    It is interesting to hear where all of this carbon is coming from. But even with all of this given information, it only adds up to 65%, where is the remaining 25% coming from and how are we able to help it? I do find it fascinating though that a majority of carbon emissions are coming from the way we build buildings.

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
