The present is key to the future Flashcards
1
Q
Palaeoclimate proxies
A
Biological, physical or chemical measurements made in geological archives that serve as surrogates for climate parameters studied by modern climatology
2
Q
Direct measurement
A
GHGs trapped in ice bubbles
3
Q
Indirect measurements
A
Tree ring width to record rainfall
4
Q
Alkenones
A
Calcium carbonate plates which can be detected by satellite pictures = a lighter colour
5
Q
Stable isotopes
A
Matter with larger amounts of heavier isotope 18^O has more positive values.
16^O is major in atmosphere the light mass is more active. Evaporated in hydrological cycle due to it being light so 18^O is first to condense due to heavier mass
