Session One Flashcards
Anthropocene
A proposed geological epoch succeeding the holocene, where the impact of men over the biosphere reaches such a level that humans become a major geological force able to shape the lithosphere
AKA human dominance of biological, chemical, and geological processes on Earth
Sustainable Development
a development that “meets the needs of the present without compromising the ability of future generations to meet their own needs.”
Denning Kruger Effect
People who are the most incompetent are the least aware of their own incompetence
The Great Acceleration
Socio-Economic and Earth System trends have experiences EXPONENTIAL growth since the indistrial age
Human impact explains ____% of current climate change
100%
How many gigatons of CO2 do we emit annually?
more than 43GT
global net anthropogenic emissions have continued to rise across all major groups of greenhouse gases
Carbon Budget
A carbon budget refers to the toal net amount of CO2 that can still be emitted by human activities while limiting gloal warming to a specified level
Carbon Budget 1.5-2 degrees Celcius in 2100
Why do temperatures continue to rise even if emissions decrease?
Bathtub analogy: Even if water input is slowed or stopped, the bathtub is already full of water. Must find way to let the water out (aka carbon sinks or “negative” emissions) if we want to reverse temperature otherwise it will only slow the increase.
Climate is a “stock problem”
Key driver for increase in temperature
Quantity of CO2 in the atmosphere (CO2 concentration), since it remains in the atmosphere for several centuries
Consequences of Bathtub Analogy
- Decreasing anthropic emissions does not lead to a decrease in average temperatures as long as we continue to emit. It only decelerates the increase
- Carbon Neutrality is a situation where mankind removes the same quanitty of CO2 as it emits. Which would stabalize the temperture not cool it
- Until then, temperature will continue to increase and we are only negotiating intensity and rapidity of temperature increases
- Decreasing average temperature required negative anthropic emissions (aka more removals than emissions)
Mitigation
Reducing impacts and sufficiency
Efficiency- learning to do better with less
Avoiding the unmanageable
Adaptation
Adapting companies to climate change / biodiversity / resource scarcity
Crisis Management
Managing the unavoidable
Mitigation vs Adaptation
Key challenge to align mitigation and adapation practices
AND avoid maladaption (i.e. AirCon)
