Exam 1: Lecture 3: Climate change, veterinary medicine, and one health Flashcards
Shrinking of ice sheets in greenland and Antartica, declining artice sea level, rising ocean levels, and coral bleaching are examples of what effect on earth?
Climate change
________ is offically the hottest year on record
2024
The planet has warmed ______ since the pre-industrial age
1.5 C
U.S. and China contribute to ____ of CO2 emissions
40%
2024 was the hottest year on record. Its also likely to be the hottest in the last _______ years
125,000 years
What is the biggest driver of the heat to cause the build up of green house gases
burning fossil fuels
Who is the overseerer of the Climate Change Adaptation and Resilience and why this particular group?
Department of Defense
- this is because increasing water levels, food supply and other issues that are important surrounding climate change
______ is naturally present in the atmosphere due to the earths carbon cycle
Carbon
What is one of the most mobile forms of Carbon?
CO2
The main problem around climate change is?
Carbon dioxide
Define Carbon Sequestration
This type of industry gets removes CO2 from the atmosphere + makes it into a form that is enviornmentally safe
- Gets out of the normal carbon cycle
The heat of the sun comes in through the atmosphere, but then is absorbed and re-emitted in all directions by ?
Greenhouse gas molecules
- Greenhouse gases act just like the glass of a greenhouse
In the greenhouse effect how does heat cause the warming of earths surface
All of the heat is not outgoing. Some heat is trapped within lower atmosphere = warming earths surface
The ______ the concentration of greenhouse gases in the atmosphere, the more heat that is trapped?
Higher
How many tons of GHG per year are released into the atmosphere
51 Billion tons
1 billion tons = 10,000 fully loaded aircraft carreries
51 billions tons = 510,000 aircraft carriers
Define Climate
Is the long-term, prevailing pattern of temperature, precipitation and other weather variables at a given location, described by statistics, such as means and extremities
Define weather
The enviornmental conditions that we expierence outside every day over a smaller, regional area
Climate Change adaption:
- The international panel on climate change describes it as adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates _____ or exploits ______ oppertunities
Harm
beneficial
How can/will we adapt to climate change
- biological
- physical / technological
- economic
- societal / cultural
- legal / policy
- systems economics
How has bacteria such as E. coli survived using Biological Adaptation
E. Coli has a cell divison rate of about once every 30 minutes
- meaning every 75 days they can do through 500 generations
How many years would it take to go produce 500 generations of cattle?
1000 years
- this is important because we have to compare how fast E.coli reproduces compared to the same amount of generations in cattle
Will lower or higher level life forms be able to adapt through natural selection faster than Higher or lower level life forms and espeically human
- We will not be able to naturally evolve a biological solution
Lower
higher
Give examples of the Impact of Climate Change on Human Health
Injuries, astham, lyme disease, respiratory allergies, cholera, air pollution, water and food supplies impacts, extreme heat and sever weather
What is defined as applying the techniques of genetics and molecular biology to the genetic mapping and DNA sequencing of sets of genes or the complete genomes of selected organisms, with organizing the results in database and with applications of the data
Genomics
Computer models suggest that blocking _____ of the suns earth bound radiation would effectively counteract the warming effect of our CO2 pollution
8%
What type of particles reflect part of the suns radiation back into space, reducing the amount of heat that reaches the atmosphere
Sulphate particles
Although Mass transport is a viable option what do we have to think about for smaller communities
may not be an option due to community, terrain and other obsticles
How can Economics be used for adaptation of climate change
- trade restrictions
- Insurance (increase or loss of insurance policies)
- Incentives
- Stock market fluctuatior
- Property valvues increasing
- Job loss / job creation
Although there is a large amount of uncertainty about exactly how climate change might impact world food production over the coming decades, will there be a positive or negative overall effect?
negative
The negative effect if climate change states further exacerbated by the growing issue of water security, which is accelerated at such a pace that two-thirds of the worlds population could live under water stress conditions by what year?
2025
How can we as a society adapt to climate change
- Job loss / creation
- Climate poverty pockets
- Climate boom pockets
- Population shifts
- Political shifts (democratic + non-democratic terror)
- Mass migration
Two german shepards use more resources just for their annual food needs than ______ average Bangladeshi use each year in total
1
- decisions may seem far fetched and far off, but it will have to be asked / thought about one day
What was the Irish Potato Famine from 1845 - 1852
During the famine, approximately 1 million people died and a million more emigrated from Ireland, causing the islands population to fall between 20-25%
What was the Dust Bowl of 1934 to 1937
The ecosystem disruption unleashed plagues of jackrabbits and grasshoppers
by 1940, more than 2.5 million people had fled from the regions affected by the dust bowl
nearly 10% moved to california
Why/How could Climate change be beneficial to Russia for example?
More areas for farming and longer farming seasons
- This is beneficial because Russia is considered the coldest country in the world
Hydrocarbons fules are _______ % of eletricity source
62%
