Lecture 3: Climate Change, Vet Med, & One Health (Exam 1)

Question 1

What are the faces of climate change we see

Answer 1

• Shrinking ice sheets in greenland & Antarctica by satellite analysis
• Declining arctic sea ice
• Rising ocean levels
• Glacial retreat in the alps, himalayas, andes, rockies, alaska, & africa
• Coral bleaching

Question 2

What was the hottest year on record (highest in 125,000 years)

Answer 2

2024

Question 3

Which two countries contribute 40% of CO2 emissions

Answer 3

US & China

Question 4

What is one of the most mobile forms of carbon

Answer 4

CO2 (carbon dioxide)

Question 5

What is carbon sequestration

Answer 5

• Taking carbon out of the air & taking it into a system where it doesn’t get recycled
• Pull excess carbon out of & takes it out of the system

Question 6

Explain greenhouse gases

Answer 6

• Act just like the glass of a green house
• The heat of the sun comes in through the atmosphere but then is absorbed & re-emitted in all directions by greenhouse gas molecules
• Not all incoming heat is outgoing
• Some heat is trapped w/in the lower atmosphere & warm the earth’s surface
• The higher the concentration of green house gases in the atmosphere the more heat is trappped

Question 7

how much of GHG are going into the atmosphere per year

Answer 7

51 billion tons (gigatons)

Question 8

Define climate

Answer 8

The long-term prevailing pattern of temp, precipitation, & other weather variables @ given location, described by statistics, such as means & extremes

Question 9

Define weather

Answer 9

The environmental conditions that we experience outside every day over a smaller, regional area

Question 10

How does the international panel on climate change describe the climate change

Answer 10

Adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities

Question 11

List some adaptations to climate change

Answer 11

• Biological
• Physical/technological
• Economic
• Societal/cultural
• Legal/policy
• Systems
• Economic

Question 12

Bovine generation time: 500 generations = how many years

Answer 12

1000 years

Question 13

Human generation time: 500 generations = how many years

Answer 13

10,000 years

Question 14

(higher/lower) life forms will be able to adapt through natural selection faster than (higher/lower) level life forms

Answer 14

Lower; Higher

Question 15

T/F: We will be able to naturally evolve a biological solution

Answer 15

False we will not be able to

Question 16

Describe genomics

Answer 16

• Applying the tech of genetics & molecular biology to the genetic mapping & DNA sequencing of sets of genes or the complete genomes of selected organisms with organizing the results in databases & with applications of the data
• Can help evolving/adapting to climate change

• Job loss & creation
• Climate poverty pockets
• Climate boom pockets
• Population shifts
• Political shifts (democratic or non-democratic or terror)
• Mass migration
