Week 9: Planetary Boundaries Framework Pt. 4 - Post 3

Planetary Boundaries Framework Pt. 4 - My Thoughts 

              This week was one of my favorites, as the final lecture was a synthesis of all previous information. The conclusions of the nine planetary boundaries is global sustainability, which was the point of the class. I am glad that I can see global sustainability as a big picture issue, now I just wish for ways to operationalize it. Since I have been through the in-depth explanations of each boundary its exciting that I understand the graphic by the SRC, or the Stockholm Resilience Center. This graphic is the focal point of their research. It was heavily referenced in the first couple of weeks, so I am glad I actually know what it means now. I am getting close to my presentation date, so I am preparing for that. I believe it will be an informative, if not complex, synthesis of all the information from this course 
              My questions for this week come from the topic of novel entities. In the lecture Dr. Sarah Cornell referenced the synthetic chemical DDT, but I am curious as to what other synthetic chemicals are considered dangerous novel entities? I wish to know what they are, where they come from, and the issues they cause? I think novel entities are a very good example of anthropogenic interference with the Earth's natural systems.

Week 3: Welcome to the Anthropocene - Notes  Lecture 1: Humanity’s Period of grace: the Holocene What is the desired state of planet earth?    On the Y axis you see that temperatures on average change with only +/-4 degrees Celsius, and that's the difference between having two kilometers of ice above our heads, and the warm, lush environmental conditions that we are so used to in the world of today. So this is one reminder of the extraordinarily important insight that the environmental conditions on Earth vary and that we have stable states. The Holocene : is an extraordinarily stable phase for human development. In fact temperatures vary with only +/-1 degrees Celsius. And even though the genetic diversity has been around for millions, often hundreds of millions of years, it is now that everything we know in terms of ecosystems, nature, the biosphere, settles in. This is where the rainforest, the coral reef s...

Week 10: Planetary Boundaries and Global Equity - Post 2

Planetary Boundaries and Global Equity               Planetary boundaries are important because they create the ceiling, or the maximum resilience, of Earth system processes. However, none of the planetary boundaries would ever be reached if not for human action. It is time to put humanity back into the equation, and find solutions for a sustainable future within the limitations and opportunities of modern society.              It is time to couple biophysical analysis of Earth system science with human dimensions. While it is necessary to think in terms of a safe ecological operating space, it is just as important to think within a just and fair operating space for people. When moving along this new pathway of thinking it is vital to recognize that no boundary operates independent of itself. Each of the nine Earth systems are interlinked with each other through feedbacks. If humanity pushes one boundary towards...

Planetary Boundaries Framework - Notes Lecture 1 – Aerosol Loading – Dr. Sarah Cornell  - Aerosol is a rather technical term to describe the phenomenon of liquid droplets or particles, very small particles that are held suspended in the atmosphere. -T hey can both absorb and reflect light, so they're important in Earth's heat balance, and in the climate system. They provide condensation nucleus points; water condenses on aerosol particles and affects where clouds are formed and where rainfall happens. And they also provide microsurfaces for chemical reactions in the atmosphere. So, they influence atmospheric chemistry. For example, the reactions leading to stratospheric ozone depletion, or the ozone hole, happened on polar clouds that formed on stratospheric aerosols in the upper atmosphere.  - Aerosols can be emitted directly into the atmosphere and they can also be formed through chemical processes in the atmosphere. That's what we call secondary aerosol. + ...
