What two words make up Anthropocene
Anthropos and Kainós
Anthropos
Human
Kainós
new
What is plutonium-239
An artificial element
Where can plutonium-239 now be found
sediment core sample (keep in mind it is an ARTIFICAL ELEMENT)
Why is plutonium-239 in sediment core samples
Nuclear weapons testing from 1950
Who were the first to use the term Anthropocene
Paul J. Crutzen and Eugene F. Stoermer
When was the term Anthropocene first used
The year 2000
What did Paul J. Crutzen and Eugene F. Stoermer think about the term Anthropocene
It signifies a new chapter were that shows the “central role of mankind in geology and ecology”
When did Paul J. Crutzen and Eugene F. Stoermer suggest that the Anthropocene started
late 1700s which coincides with the steam engine becoming popular and the amount of greenhouse gases started to grow in the atmosphere
What is the late 1700s commonly labeled
the beginning of the Industrial Revolution
Great Acceleration
when many of the developments that began around
the start of the Industrial Revolution increased in
number.
Ice ages
cycles of cold periods
Anthropogeneic
Human-related
What has sent the Earth’s climate into warming instead of cooling
Anthropogenic causes
Charles Dickens
A British writer that popularized the modern think process about the industrial revolution; large, fiery factories fueled by coal and lines of workers standing in front of machines, covered in dust
Why is the start of the Anthropocene at 1950 and not at the 1800s
Because the size of the emissions grew exponentially at the 1950 not the 1800s
Who labeled the increase in greenhouse gases starting in 1950
J.R. McNeill
What did J.R. McNeill call the increase in greenhouse gases starting in 1950
the “Great Accleration”
What was a key factor of the Great Acceleration according to J.R. McNeill
The rise in the global human population
What was the human population at 1780, the start of the Industrial revoultion
less than a billion
What was the human population in 1930
2 billion
What is the current population
8 billion
How did much the population increase from 1930 to the present
the population quadrupled from 1930 to the present
Do rising carbon dioxide levels effect all of the levels of the atmosphere in the same way
No
Is the troposphere getting hotter or colder
it is getting hotter
Are the layers above the troposphere getting hotter or colder
the layers above it are getting colder
What happens when difference parts of the atmosphere heat up and cool down
it causes problems
What must we look at to understand the releasing of greenhouse gasses into the environment by humans
Human social and political history
When did people become aware of the consquences of burning fossil fuels
After mechanisms for extracting and burning fossil fuels were developed
Eunice Newton Foote
mid nineth century scientist (1819- 88)
What Eunice Newton Foote argue
She argued that the atmosphere water vapor and carbon dioxide could interact with solar rays to raise the temperature of the Earth
