Climate DATA, Feedback Loops, Albedo Flashcards
How do Scientists study Earth’s climates
Temperature and Rainfall (Rulers and Thermometer)
What are the limitations of satellite and instrumental records when studying climate
satellites and instruments have not been around forever
Where can scientists find clues about climate for timeframes before the 19th century
tree rings, glaciers, records
Why are layers, bands, and rings in natural enviromental records useful to studying climate
They tell seasons, temperatures, rainfall, and age
Can scientists use evidence from one form of data to determine the details of an ancient climate? Why or Why not?
No because not every place has the same climate, like not every place has trees
Data is an estimate
Proxy (Indirect) data
examples of proxy/indirect data
tree rings, ice cores, corals, lake and ocean sediments, tree pollen, or human archives
direct measurement example
current temperature and CO2 levels are in the atmosphere
How is direct measurement collected
air samples and greenhouse gases
__% solar radiation is reflected back to space

__% solar radiation is absorbed by the earth’s system
70
__% scattered and reflected by clouds
20
__% absorbed by clouds
51

4
__% absorbed by atmosphere and clouds
19

6
Radiation is absorbed by
the earth and ground
% of the suns energy that is reflected by the surface
albedo
light surfaces
high albedo
dark surfaces
low albedo
the effects of global climate change are widespread and can trigger futher change
feedback loops
