Chapter 2 Flashcards
What is the IPCC? When was it created? What does it do?
- Intergovernmental panel on climate change
- the top association of climate scientists
- created in 1988
- scientists volunteer to provide a summary of what is known about the drivers of climate change
- UNFCCC binds member states to work toward an international treaty on climate change
What is the NIPCC
- Non-governmental panel on climate change
- organization of climate deniers funded by fossil fuel companies
What percentage of people actual deny climate change according to a Harvard study?
10%
Why is there debate over the reality of climate change?
- because it is both a physical phenomenon and a set of cultural ideas
- our discussions about climate change as a physical phenomenon are filtered though ideas about what it means to us (threat, challenge, blessing, etc.)
Greta Thunberg and EU’s largest school strike
- 1.4million students joined Greta to protest climate change
- what is your circle of influence?
Our Children’s Trust and Kelsey Juliana
- sued the US government in 2015, claiming they violated the younger generation’s rights to life, liberty, and property
- climate change as an issue of inter generational justice
Climate Fatigue
hearing too much about climate change, fear you cant help, and hoping it wont be so bad; fed by corporations
Climate Denialism
emotional state similar to denialism that mourners and victims of trauma experience; usually related to deep beliefs in conservatism, market fundamentalism, and Christian doctrine
What is climate change?
- long term pattern of temperature and precipitation averages and extremes at a location (NOAA)
- WMO requires 30yrs of data before determining a ‘normal’ climate
Climate vs. Weather
- Weather = what’s possible for temperature and precipitation in a location
- Climate = what is likely
- with climate change, extreme weather is more likely
What is the Holocene and what is its significance to climate change?
- The Holocene is the period that humans evolved in
- it had an unusually stable, warm climate which allowed humans to create agricultural civilization
- If our current environment conditions have changed from those of the Holocene period, civilization must change as well
What causes climate change?
- Changes in atmospheric chemicals (greenhouse gases)
Increases in carbon dioxide, methane, and nitrous oxide trap more solar radition
What are environmental “sinks”?
things like soil, plants, and oceans which can absorb some greenhouse gases
What is anthropogenic climate change?
climate change caused specifically by humans
How does lag time relate to climate change?
- The Earth has a lag time between a change in course and when you actually see the results of said change
- you won’t see the changes until the moment they instantly happen
- we are just beginning to see the effects of climate change
