Evidence of climate change Flashcards
1
Q
What are 4 ways we can prove that climate change exists
A
- rising sea levels
- tree rings
- Ice cores
- extinction of species
(+change in global temp and increased frequency in drought and forest fires, along with flooding)
2
Q
what do tree rings show
A
- how old a tree is
- what weather conditions were like for each year
3
Q
what do ice cores show
A
- how much carbon is in the air from the past
4
Q
what does extinction of species show
A
- species used to thrive and now find it hard to survive
5
Q
what does rising sea levels show
A
- the ice caps are melting (causing flooding)
6
Q
what way can we get the best evidence for climate change?
A
tree rings and ice cores. This is because it is scientific evidence and not politically motivated
