News report and educational content raising awareness of climate change refers to the
Anthropocene
For Paul Crutzen and Eugene Stoermer, “Anthropocene” designated a new geological epoch that recognizes the
“central role of mankind in geology and ecology”
What did the Anthropocene coincide with in the late 18th century according to Paul Crutzen and Eugene Stoermer
The popularization of the steam engine and early records of growing greenhouse gas concentration in the atmosphere
What did the AWG offer a list of that is associated with the Anthropocene
phenomena
The Holocene is best described as what kind of period
interglacial
What was the Holocene characterized by
the significant ice cover across the globe
What influences the interaction between solar energy and the Earth System
The orbit of Earth
Led to previous cycles of ice ages and interglacials
the orbit of Earth
Set the Earth’s climate in the direction of rapid warming instead of a cooling period
Anthropogenic/Human-Related causes
A study of what shows the largest warmind trends
temperature variability
Is happening more evenly around the glove than past climate change
Global Warming
Cooler temperatures on average does not mean
temperature were cooler everywhere at once
What was LIA caused by
solar forcings and volcanic forcings
Discussions of the Industrial Revolution brings to mind
large coal-powered factories and soot-covered workers who were sometimes still children
Paul Crutzen And Eugene Stoermer argued making the popularization of the what is the starting date of the Anthropocene
Steam Engine
The introduction of the coal-powered steam engine was a land moment in the history of
humans burning fossil fuels to produce the energy that powers the machines
1800 might have marked the start of technology that has
resulted in large greenhouse gas emissions
A story of the human conquest of nature and of the human capacity for perpetual growth
the Industrial Revolution
What began to increase around 1950
The scale of human activities that altered the Earth System
A key factor in the “Great Acceleration”
the rise in the human population
New research supports that what is causing global warming
higher concentrations of carbon dioxide and other greenhouse gases in the atmosphere
What causes different types if changes at different layers of the atmosphere
Rising carbon dioxide levels throughout the atmosphere
Temperatures are rising in what layer of the atmosphere
troposphere
Which atmosphere layers is air thinner and colder
The higher layers
What is created due to the different temperature reaction in the atmosphere layers
instability
What do graphs that represent the correlation between high greenhouse gas concentrations and rising global surface temp. not show
Why or how humans are releasing those gases into the atmosphere
Fossil fuels are formed from
the remains of living organisms from past geological epochs
Where are the remains of living organisms that form fossil fuels located and what is the carbon restricted from doing due to it
The remains are stored within the Earth, so the carbon in the fossil fuels won’t interact with the Earth’s subsystems in the surface
How do humans utilize fossil fuels
Burning them for energy
What was coal burned for in the 19th century
To power steam machines
What was coal continued to be used for in the 20th and 21st centuries
Power electric plants and petroleum, and to power machines
