Final Review Flashcards
Define Weather:
Short term natural events in a place
Define Climate:
Long term weather trends often defined by temperature and precipitation
Define Climate Variability:
Deviations of climate variables
from a given mean state at all spatial and temporal scales
beyond that of individual weather events
Define Climate Change:
A change in the state of the climate
that can be identified (e.g., by using statistical tests) by
changes in the mean and/or the variability of its properties
and that persists for an extended period
What are some key insights from the paleoclimate record?
Climate has been in constant flux throughout the history of Earth, but it is not warming at an unprecedented rate
What are the 5 natural drivers of climate change?
Global energy balance, sun spot cycles, earth’s orbit, volcanoes, and ocean cycles
What are the physical effects of increasing CO2 concentrations in the atmosphere?
Increased greenhouse effect – rising global temperatures, sea level rise, extreme weather events, desertification, etc.
Define a climate impact:
The consequences of realized risks on natural and human systems due to climate change.
Define a Hazard:
The potential occurrence of a natural or human caused physical event that could cause loss of life or injury, and/or cause damage to infrastructure
Define exposure:
The presence of people, services, social or cultural places that could be effected by a hazard
Define vulnerability:
predisposition to be adversely
affected… [as a] product of intersecting social processes
that result in inequalities in socioeconomic status and
income, and are exacerbated by exposure
List 5 categories of climate impact that the IPCC tracks:
Water scarcity, agriculture/crop production, infectious diseases, heat/malnutrition/other, and damages to infrastructure
Climate risk =
hazard + exposure + vulnerability
What are 5 key takeaways about global climate impacts?
- climate impacts everything
- hazards have generally gotten warmer and more extreme
- a little bit of warming can make a big difference
- not all impacts are negative
- some impacts are reversible, others are not
- impacts are compounding and cascading
According to Eve Darian-Smith, what are the 3 ways to interpret wildfires?
- About fire (empirical dimensions)
- With fire (relational dimensions)
- Through fire (spatial/temporal dimensions)
