Earth System Science (ESS)
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?
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 science or environmental science?
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 - esecially in Antarctica are found in these archives.
What are ice cores?
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 climatology or environmental science?
This is the study of Earth's land, oceans, and atmosphere as a single system.
What is Earth System Science (ESS)?
Cloud cover that cools the Earth by blocking sunlight is an example of this feedback.
What is a negative feedback?
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?
Reactions that push climate change in the same direction as the original forcing.
What are positive feedbacks?
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 young activist has brought attention to the climate crisis.
Who is Greta Thunberg?
Methane is an example of this group of compounds, but this is the most detrimental.
What is CO2?
These feedbacks can push climate change to a tipping point.
What are positive feedbacks?
Tree ring analysis to study past climates
Dendochronology is the study of?
The concept of the Anthropocene suggests climate change is different today than in the past because of this.
What is human activity?
Combining climate history and human history helps us better understand this.
What is our changing climate/climate change?
