Climate Change, Veterinary Medicine, & OH (3) Flashcards
What are the faces of climate change?
- shrinking ice sheets in Greenland & Antarctica by satellite analysis
- declining arctic sea ice
- rising ocean levels
- glacial retreat
- coral bleaching
2024 may be the hottest in the last ______ years
125,000
Which initiative clears the way for looking at climate change adaptation and resilience?
DoD Directive - Climate Change Adaptation & Resilience
What is the most mobile form of carbon?
carbon dioxide
What is carbon sequestration?
taking carbon out of the air and putting it into a system or process where it’s not recycled, gets out of normal carbon cycle
What is the greenhouse effect?
the heat of the sun comes in through the atmosphere but then is absorbed and re-emitted in all direction by greenhouse gas molecules
Why are greenhouse gasses bad?
not all of the incoming heat is outgoing - some heat is trapped within the lower atmosphere, warming the earth’s surface
the higher the concentration of greenhouse gases in the atmosphere, the more heat is trapped
What is climate?
the long-term, prevailing pattern of temperature, precipitation, and other weather variables at a given location, described by statistics, such as means and extremes
What is weather?
the environmental conditions that we experience outside every day over a smaller, regional area
What is climate change adaptation?
adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities
What is Bovine Generation Time?
calf to replacement calf time = 357 days breeding
500 generations = 1000 years
biological adaptation through genetic modification will take much longer than in e. coli - every 75 days =10.714 weeks 500 generations
What about human generation time?
500 generations = 10,000 years
What is the bottom line with adaptation?
lower level life forms will be able to adapt through natural selection faster than higher level life forms and especially human
What is the impact of climate change on human health?
How might genomics be altering beef herds?
select genes for heat tolerance
What is climate engineering?
spreading various compounds in the air to help combat what we see with the climate
doesn’t work well
How can we counteract the warming effect of our CO2 pollution?
blocking 8% of the sun’s Earth-bound radiation
sulphate particles reflect part of the sun’s radiation back into space
What can help decrease the burden of CO2?
other forms of power
What are the economic impacts of climate change?
- insurance
- incentives
- stock market fluctuation
- property values
- job loss/job creation
T/F: Although there is a large amount of uncertainty about exactly how climate change might impact world food production over the coming decades, there is general consensus that the overall
effect will be negative
TRUE - also water scarcity 2/3 population
What are the societal impacts of climate change?
- job loss/job creation
- climate poverty pockets
- climate boom pockets
- population shifts
- political shifts - democratic, non-democratic-terror
- mass migration
What is 62% of our electricity source?
hydrocarbon (fossil fuels)
