Week 7: Planetary Boundaries Framework Pt. 2 - Post 3

Planetary Boundaries Framework - My Thoughts 

          This week was a nice review of my learning from last year. I got a refresher on climate change and ocean acidification. However, it also added new information. I learned about specific, quantitative tipping points and control variables. I also had to look up the current concentration of carbon dioxide in the atmosphere. I was shocked when I realized it had risen by 2 ppm since only a few months ago. We really are emitting carbon dioxide at exponential rates. This week was a bit easier then previous weeks. It was all focused science and less theory. I think that I like learning from a more scientific base then a theoretical one. But, that isn't to say I am not completely enjoying this course, because I definitely am. 
          For this week I want to know exactly the boundary for stratospheric ozone depletion. The lecture noted the control variable, which is the ozone's thickness, but not what the threshold is or how close we are too it. I only know that we are in a danger zone.

    How did "they" get people to understand the issues with the ozone layer caused by the use of aerosols?

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. + ...
