Earth System Science (ESS)
This is the study of Earth's land, oceans, and atmosphere as a single system.
What is Earth System Science (ESS)?
Reactions that push climate change in the same direction as the original forcing.
What are positive feedbacks?
The natural repository of clues about past climate conditions is called this.
What is the archives of nature?
This term describes the new geological era heavily influenced by human actions.
What is the Anthropocene?
The study of climate using information from nature and society is known as this.
What is climate history?
ESS views the Earth as this, composed of interacting subsystems.
What is a single system?
Melting polar ice, which further warms the climate, is an example of this type of feedback.
What is a positive feedback?
Human-produced records of past climate conditions are found in these archives.
What are the archives of society?
The Anthropocene is proposed to have begun around this year.
What is 1950?
This field scrutinizes claims about climate's impact on human society.
What is the history of climate and society (HCS)?
These are the four subsystems in ESS.
What are the geosphere, hydrosphere, atmosphere, and biosphere?
Feedbacks that counteract the original forcing and moderate climate change.
What are negative feedbacks?
Can reveal atmospheric conditions from as far back as hundreds of thousands of years through this technique.
What is ice core sampling?
The current geological epoch we live in, according to the formal geological time scale.
What is the Holocene?
The term for the idea that climate determines the course of human history.
What is climate determinism?
The geosphere consists of all the land, earth, and rock, and is sometimes called this.
What is the lithosphere?
Cloud cover that cools the Earth by blocking sunlight is an example of this feedback.
What is a negative feedback?
This type of record provides precise and accurate information about climate trends.
What are instrumental records?
The Anthropocene emphasizes the role of these in the current climate change.
What are human actions?
This historian pioneered the field of climate history by using sources from society.
Who is Christian Pfister?
External forces that alter the climate and cause reactions are known as these.
What are forcings?
These feedbacks can push climate change to a tipping point.
What are positive feedbacks?
Analyzing tree rings to study past climates is known as this.
What is dendrochronology?
The concept of the Anthropocene suggests climate change today is comparable to these.
What are past geological epochs?
Combining climate history and human history helps us better understand this.
What is our changing climate?
