Geoengineering

Question 1

What was the CO2 level in 1950 and what is it today?

Answer 1

Was 300ppm and is now 400ppm.

Question 2

What is the keeling curve?

Answer 2

Plots the ongoing change in concentration of CO2 in the earth’s atmosphere since the 1950s.

Question 3

What does Geoengineering refer to?

Answer 3

Large-scale efforts to diminish climate change resulting from greenhouse gases that have already been released into the atmosphere.

Question 4

What are the two main types of GeoEngineering?

Answer 4

Solar Radiation Management (SRM)

Carbion Dioxide Removal (CDR)

Question 5

In what ways can SRM be implemented?

Answer 5

Whitening roofs
Growing reflective crops (ineffective)
Brightening marine clouds (ineffective)
Atmospheric aerosoles (effective)

Question 6

What is the termination effect?

Answer 6

Refers to the consequenes of a sudden halt or failure of the geoengineering system

Question 7

Would could failure of geoengineering lead to?

Answer 7

Failure of Geoengineering systems could lead to relatively rapid warming which would be more difficult to adapt to than climate change itself. Risky game.
