1. Climate Change: Evidence
Why did we focus on climate over the past ~400,000 years in our discussion of climate change?
Continents and mountain ranges were much like they are today.
Controls on climate should be similar, with human influence perhaps the

Continents were in similar places as they are now so
it is a good benchmark for whats happening now.
Ice cores that we have contained also go back
400,000 years. Sun controls the temperature. Albido

In a sequence of sedimentary rocks, the oldest layer is at the bottom and is overlain by
progressively younger layers
the scientific law that describes the age relationship between sedimentary rock layers is
called the law of superposition (law of superpo
